How PPC can make your business, and how click fraud can break it...

Digital marketing has opened up the world to everyone. Where once your small company might have struggled to make an impact in your local area, now the world is your oyster by using pay per click advertising (PPC) and whole world of marketing tools.

In 2020 more than 4.57 billion people in the world are connected to the internet, and more than 2 billion of those buy online. For every business nowadays a well targeted PPC campaign is the difference between sinking and swimming.

Add in the fact that there are 5.6 billion searches on Google every day, and you’ll understand how big a deal PPC is.

But in any bustling marketplace, there are always more than a few rats.

Permanently lurking around the online marketplace, click fraud is one of the most damaging and thriving practices. Click fraud works by targeting your PPC campaigns, causing you to lose money, miss out on valuable sales opportunities and could even, potentially, put you out of business.

There is a whole industry that has been built up to defraud internet advertisers and users. This includes hackers, app and bot developers, click farms and even sneaky business rivals.

The issue of click farms is widely reported, often used for artifically inflating engagement on social media or spreading ‘fake news’. But click farms can also be used for more traditional financial fraud, with enterprising gangs making millions a day using complex technological solutions and malware.

In fact, these click farms are available for hire for anyone willing to pay for their services – not just criminals.

Is click fraud really that damaging to your business? Well, there are a lot of factors that can come into play:

  • Competitiveness of your industry
  • Amount of money at stake on each click (Cost Per Click)
  • Visibility of your campaign

Not every business has the same risk when it comes to click fraud.

But, as a general rule, if your cost per click is high, your industry is very competitive (I mean, aren’t they all) and you run an extensive PPC ad campaign then you are very likely at risk of click fraud or ad fraud.

Although you will find click fraud in almost any industry, it’s very likely in the following:

  • On-demand services such as plumbers, locksmiths etc
  • Financial services
  • Medical and dental services
  • Legal services such as lawyers
  • Telecoms 

These high cost and high volume services are of course a magnet for fraudsters. But, you don’t have to be KPMG or Bank of America to get hit by click fraud.

Competitive local service markets are also prime territory for click fraud. This competitor click fraud is where rival businesses click on your paid search results to sap your ad budget and stop your ad showing up.

Locksmiths, plumbers, dentists, real estate and waste disposal  are all industries with relatively high cost per click and often fierce local competition. 

This guide to click fraud will be taking an in depth look at what click fraud is, how it affects businesses and how to avoid it.

A Brief History of PPC

Where were you on the 6th August 1991? Well, you may or may not have even been born, but that’s the day the World Wide Web ran its first web page.

Tim Berners Lee, a British computer scientist who had been working at CERN in Switzerland proposed that by networking computers via phone connections, we could share data around the world.

It took a few years for it to catch on, with browsers becoming available for the Commodore Amiga, Unix, Windows and Mac OS in 1993.

Anyone remember Netscape?

The beginning of online advertising. How did it all start?

But it’s in 1994 that much of the online activity that you might recognise today started to happen. With around 11 million American households equipped to get online, we saw the White House launch a web presence; the first online purchase – a pepperoni pizza from Pizza Hut; the launch of Yahoo! – which was the Google of it’s day; the first piece of spam mail and… The first ever online banner ad.

American telecoms company AT&T paid $30,000 to website (now to place a HTML banner ad on their homepage. The incredibly simple design said:

“Have you ever clicked your mouse right here?” with an arrow pointing to a separate piece of text saying: “You Will”.

the worlds first ever PPC ad

Once they clicked on the banner users were taken to a landing page that took them on a tour of the world’s greatest museums. So it wasn’t even a blatant sales approach, it was designed to encourage engagement and built AT&T as a brand that offered information. An early form of content marketing…

That banner had a 44% click through rate!

Today’s marketers are happy to see an average click through rate of around 0.5%…

Of course, today’s internet users see hundreds, possibly thousands of ads a day. But at the time, the process was unique. A way for websites to monetize their content so they could pay writers? Who would think that would catch on?

But sure enough banner ads became one of the most popular forms of online advertising, with sites like Time getting in on the act, and with companies paying anything up tothousands of dollars to place their banner ads on websites.

Targeted and sponsored ads

With banner ads becoming commonplace, advertisers started to wonder if there were ways to target specific demographics. Up to this point, advertisers had simply hired space on whichever web page they wanted and their ad would be displayed for a set amount of time.

An advertising company called WebConnect were one of the first to pioneer tracking user activity online and using algorithms to change the adverts shown on a web page. Before this, a banner ad was static for the duration of the advertising contract. By using WebConnect, a company could add their banner ad to a variety of different websites based on price and demographic.

Another breakthrough was being able to rotate banner ads on websites to avoid ‘banner fatigue’. Once a site visitor had been shown a banner two or three times, the banner would change, a clever tactic designed to catch the attention and maximizing the chances of a click through.

In 1996 came DoubleClick, another online advertising agency that made it easy for companies to find the right site and for websites to make money from ads. In fact, DoubleClick’s ability to give websites easy access to advertisers caused a rapid expansion in the amount of websites offering advertising space.

Add in the ability for advertisers to track their ROAS and to customize their ad spend by focusing on high performing websites, and you had the fuel to the fire for online marketing.

The software underpinning this was D.A.R.T (Dynamic Advertising, Reporting and Targeting) which gave advertisers an easy way to see where their money was going. DoubleClick were also one of the first sites to bring in a new pricing model for online advertising; CPM or Cost per Mille, meaning advertisers were now paying for the ad’s performance, not just for it’s placement.

The rise and rise (and rise) of Google

Around this time, two students at Stanford University called Larry Page and Sergey Brin were developing a piece of code that was designed to make sense of all of the websites that were popping up every day. Their program, ‘Backrub’, was part of their mission to organise the masses of information that the internet was spawning by categorising links.

Sites like Yahoo!, Excite, Lycos, AOL and AltaVista were the search engines of choice for most internet users in the 90s. And although they worked, their algorithms were perhaps too simplistic for the growing World Wide Web.

For example, Yahoo! required a team of real people to input websites into its database so that when you ran a search it would show in the results. If you hadn’t submitted your website to Yahoo! then it wasn’t going to show up.

At the time it was a revolutionary approach, and one that put a huge strain on sites like Excite and AltaVista who used simple text searches to find results.

But Page and Brin had worked out a way to map the relevancy of a website to a user’s search terms by a complex web of link crawling, keyword analysis and PageRank, or relevancy. At a relatively early point the project got renamed Google and with an investment of $100,000 from the co-founder of Sun Microsystems, Andy Bechtolsheim, the Google project began its ascendency.

Although early websites like Yahoo and Lycos also offered a sort of online directory, news pages and weather reports, Google kept it simple. Their thing was search results and the more the word got out about how effective Google was, the more they grew.

At some point between 2000-2001, Google became the dominant search engine and the phrase ‘Google it’ was born. Even Yahoo! switched it’s search engine over to Google to make sure people didn’t stop using Yahoo!

Google gives birth to AdWords and AdSense

Having cornered the marketplace in effective search results, Google had to monetise. Between August and October 2000, Google launched its Premium Sponsorships and AdWords platforms.

Using Premium Sponsorship enabled advertisers to pay to have their company appear at the top of the Google SERPs on a CPM basis. Whereas using AdWords meant that your advert would appear as a text banner on the side of the search results. Although at the time Google was still in it’s relative infancy, the popularity of the service took of quickly.

In 2003 Google launched their AdSense platform which allows publishers to host advertising on their websites and make money from clicks and views. Like DoubleClick, it revolutionised how website owners could get paid for their content.

Suddenly you didn’t need to be selling anything, or even have an online shop… You could set up a blog or information portal and host ads and banners and get paid. All you needed to do was channel the traffic.

So by offering the most efficient search results and giving people what they were looking for easily, Google became the dominant search engine. Then by giving businesses a way to maximise their visibility on these search results, they built a growing tide of income that would establish them as one of the world’s biggest tech companies.

And then, by offering publishers a way to host and get paid by adverts, Google became the world’s biggest advertising agency.

With their growth Google continue to offer highly effective tools to manage, research and track your advertising spend: Analytics, Trends, MyBusiness…. Today there are something like 251 Google services, covering everything from productivity and study to entertainment, web browsers and actual hardware.

The Other Guys: Facebook, Amazon & Microsoft

As Google grows to become the dominant search engine, other players are doing their thing. As a savvy internet user, you’ve no doubt heard of some quirky startups such as Facebook and Amazon. Both of these popular platforms have grown alongside Google to become the biggest at what they do.

Put simply, Facebook has built itself from a simple platform for interaction with the world, to an ever bigger social media platform. Encompassing Instagram, WhatsApp and Oculus (virtual reality), with around 2 billion users of its platform every month.

Amazon have gone from being a bookshop to the world’s online superstore. With acquisitions including Whole Foods, Ring (a home security company), Pillpack (an online pharmacist) and Twitch (gaming and video).

In this history of the internet, this is the first real mention of Microsoft, who have been in there the whole time. Their Windows operating system has powered the internet from the start, but their presence away from the OS hasn’t been the most consistent. However, their search engine Bing is still the second biggest search engine with over 9 billion searches a month. Microsoft also own Linkedin, Skype, Nokia, MultiMap and a whole glut of software companies.

When it comes to PPC campaigns, although Google is the leader for search engines, each of these have their own speciality that can be harnessed.

And that brings us to the issue of click fraud and how it could affect you, the modern marketer.

How click fraud works

As PPC campaigns have become more complex, allowing us different ways to target demographics and a multitude of ways to pay for our advertising, so has click fraud become more sophisticated.

But what is click fraud?

Put very simply, click fraud is the act of clicking on a pay per click advert with no intention of buying or using the product or service. It is usually done with the objective to divert or negatively impact the advertisers budget.

There most common reasons to get fake clicks on your PPC ad campaign are:

  • Vindictive competitors or customers who want to negatively impact your ad spend
  • Organised criminals who have created a way to get paid for clicking your ads
  • Apps or software created to collect the payout from ads (often with some help from bots)

When you consider that the price for some keywords in Google Ads (previously known as AdWords) can be upwards of $50, or over $100 per click, you’ll soon see why multiple fraudulent clicks can really start to add up to a bigger problem.

In 2017 it was estimated that around 1 in every 5 clicks on a PPC ad campaign were fraudulent in some capacity. Since then, the techniques have become more advanced and the sheer volume of fraudulent activity online has increased. A study by the University of Baltimore estimates that the cost of click fraud will reach $23.7 billion by the end of 2020. Some estimates of modern click fraud put the amount of fraudulent activity at 1 in 3 clicks.

What are the main sources of fake clicks or click fraud?

If clicking on someones ad repetitively sounds like a lot of hard work, you’d be right. A competitor clicking on your ad five or ten times a day might be a drop in the ocean for your advertising spend, but there are more damaging ways to create fake clicks.

High volume clicks:

Bots and web crawlers

Designed to crawl the web looking for information, usually for spam or data collection purposes. There can be ‘friendly’ bots, which are just looking to scrape contact info for example. Or deliberately vindictive bots which have the sole purpose of clicking on your ads hundreds or thousands of times to deplete your ad budget.

The issue of bot traffic is a complex one, with bots coming in a huge variety of flavours. Take a look at our guide to bot traffic to understand this issue in more detail.

Click Farms

Either automated set ups, or human powered factories designed to click multiple times on specified links. Yes they do exist, usually in developing countries where people can be paid as little as $5 for 100 clicks.

Click farms are used by all sorts of businesses, often to inflate their following or engagement, and they can be hired to do multiple actions, from liking social media accounts, watching videos, sharing links or information, leaving comments and, of course, clicking on PPC adverts multiple times.

Although the bulk of click farms can be based in developing countries, there have been increasing instances of click farms based in Europe and the USA. By hooking up phones and tablets to a computer, you can automate the activity of hundreds of people.

We recently carried out our own research about this phenomenon, so read all about click farms here.

Fraud rings and bot networks

Criminal gangs establish a mixture of publisher websites and automated bots to defraud advertisers. One of the best know is Methbot, a highly sophisticated scam bot network, with a complex set up which is designed to fraudulently collect the payout on video views using a network of computers. Thought to have originated in Russia, methbot is estimated to make around $5-6 million each day in fraudulent clicks.

Ad fraud

Publishers create a website designed to host banner and text ads, then channel fake clicks through the website to collect a payout. Ad fraud often involves placing ads on websites with little chance of genuine traffic being able to find it, but with the opportunity for the site owner to maximise their income.

As a complex issue with many threads, you can check out our ad fraud guide for more information.

Medium to low volume clicks:


Your direct competitor can try and siphon off your PPC budget so that their ad ranks higher for relevant searches. They might just click your ad every time they see it, or they might instruct everyone in the office to click your ad – which could be potentially quite damaging.

Although competitors can try to manually inflate your PPC spend, you might find that this is a temporary measure or occasional practice.

We actually looked recently at a case of competitor click fraud, where a business orchestrated a campaign against local competitors. You can read the case study here.

There are some simple steps to minimise your exposure to competitors clicking on your ads, which we will look at later on.

Human error

People searching for something may accidentally click on your site in the SERPs, but then click out again. They may not even realise its a paid ad. Technically this wouldn’t be classed as click fraud, but an invalid click. There is no strategic sabotage going on here, it’s simply a mistake, although repeated mistakes can cost advertisers a fair amount of money.

Vindictive parties

Your ex employee, unhappy customer or even your sociopathic ex might have a reason to click multiple times on your ad just to pee you off. You’d best go and apologise.

Is it really that big a problem?

Now, you’re probably wondering why the hell would anyone really want to go to all that trouble. Is this really something that people do?

If you haven’t already then run a quick search for ‘buy clicks’. What you’ll find is a whole industry built around fake website traffic, often designed to boost views on websites or inflate the popularity of social media accounts.

Sites like Fiverr offer plenty of options for users to buy ‘likes’ or website traffic. And most of these services can, of course, be used maliciously.

Many marketers can also run bots to find new clients or to build an email list which they can sell. These simple bots may not be fraudulent, but with enough of them you could be looking at losing quite a lot of money through non purchasing site visitors.

Bots can be used in a variety of ways and are relatively simple pieces of programming, meaning that pretty much anyone with a decent level of coding knowledge can make their own bot. You can also buy bots from a variety of sources, for everything from research to more nefarious purposes.

It’s a been proven that the bulk of internet traffic is actually bots, with some sources estimating 40% and others putting the figure at upwards of 50%. So when you’re aiming to run your next PPC campaign this is definitely an issue that you’re going to have to bear in mind.

Those running a PPC campaign might find that the amount of click fraud, sits around 20% of their total traffic. Bear in mind that Google doesn’t refer to the practice as ‘click fraud’ but prefers the term ‘invalid clicks’. This covers all bases from genuine mistaken clicks to the actual vindictive bot or click farm traffic.

Who is affected by Click Fraud?

You might think that click fraud is the kind of thing that only really affects the big boys; the Amazons, Citibanks and Hiltons of this world. Of course, they are in the firing line as they target high value keywords. But in reality every online business is at risk from click fraud to some degree or another.

Automated click fraud doesn’t discriminate, with bots often just scouring the web for specific search terms. Even accidental clicks can really add up if your banner or sponsored result is in a competitive industry.

There are 3 industries in particular though, that are more vulnerable to click fraud than others. According to a 2015 Bloomberg click fraud report, the 3 most affected industries or categories of business, are finance, family, and food. The reason for this is that they all have a relatively high cost-per-click (CPC) and search volume.

An industry with a huge amount of traffic and expensive keywords means more room for fraudsters to hide. It also means less risk of getting caught and a higher payout. Here at ClickCease we see that the most affected micro industries are: locksmiths, lawyers, water damage repair and… dentists. It seems that local service providers are prone to a higher rate of click fraud due to the competition, high CPC and the knowledge of the market.

No matter how little or how much money gets spent on campaigns, one thing is for sure. Every company that’s using PPC networks like Google AdWords or Bing Ads, is either vulnerable to click fraud or has been a victim of click fraud.

High profile cases of ad fraud

On occasion some of the bigger cases of click fraud make it into the press, especially when there is some serious money at stake. These examples can be on the more extreme end of the click fraud spectrum, but they give a good insight into the lengths some people will go to.

Like other forms of fraud, those big example are just the tip of the iceberg, with many smaller click fraud campaigns hiding under the surface.

The botnet hacker

Italian citizen Fabio Gasperini was sentenced in 2017 to one year in jail in the USA, as well as a $100,000 fine as a result of his involvement in a botnet hacking scam. Gasperini targeted servers which are used by companies for large scale data storage and transfer, gaining control of these servers to use as simulated web browsers.

Gasperini was able to use the servers to set up a network of around 100,000 computers around the world and use them to send automated clicks on ads which were embedded on websites that he owned. He also defrauded big businesses that were paying for these ads, including Nike and Walt Disney.

When you consider that one man was able to do such extensive damage, it just goes to show what can happen when you have a seriously organised criminal network.

We also looked at this case on the ClickCease blog back in 2017…

Search engine clampdown

Microsoft and their Bing search engine are the second biggest player in the PPC world (excludng social media sites), and they have been known to take click fraud very seriously. Back in 2009, Microsoft sued a family team based in Vancouver, BC for their part in a click fraud scam designed to drive traffic to their World of Warcraft and auto insurance based websites.

Microsoft were awarded $750,000 in damages, although they also stated that they lost out on $1.5 million in refunds as a result of fake clicks by the scammers.

Criminal bot networks

We mentioned Methbot earlier, but this huge criminal scam is a long running and hugely profitable bot network which is designed to make money off video advertising. The network makes around $3-5 million a day by using fake websites to stream videos, racking up views and huge payouts.

It is alleged that the gang have set up around 250,000 URLs that host video adverts which rack up around 300 million video ad views each day!

The sophistication of the Methbot set up is staggering, with domain names made to look like they belong to well known brands like ESPN and Vogue, around 570,000 bots and the software making the interaction with the videos look like genuine human behaviour.

Another sophisticated bot setup which was uncovered in 2017 is Hyphbot. With around a million URLs registered, Hyphbot was a prime example of ad spoofing; a practice where fake websites are made to look like big name publishers like The Economist or The Financial Times. Advertisers then place their ads on these spoofed sites which then receive a high volume of bot traffic, inflating the PPC payout.

Although there has been a decline in Hyphbot related activity, it is still thought to be active and making around $500,000 a day.

The click farm

One of the biggest click farms ever discovered was in Thailand in 2017. With around 500 smartphones linked up to 350,000 SIM cards and 9 computers, the click farm was connected to criminals from China who used the click farm to boost likes and engagement on Chinese social media sites.

The owners of the click farm were allegedly paid $4400 a month to run the set up.

Bangladesh and India are also regularly listed as some of the top places to set up click farms, thanks to the low wages paid to workers. One report suggests that workers paid $120 a year work in shifts to click on multiple smartphones liking posts and following profiles on sites like Facebook, Instagram and Twitter.

The next time you see an Instagram account which seems to have an unfathomably large following, it might be thanks to click farms. In fact many popular influencers and business accounts, and even some celebrities have used click farms to inflate their popularity online.

When it comes to Google Adwords fake clicks, companies who want to waste their competitors advertising budget can easily hire a click farm to click on ads. A simple search online will net plenty of places where you can buy fake clicks for a low price, for whatever purpose you want. Click farms are a very real and growing business.

Preventing invalid clicks in Google ads campaigns

Dealing with invalid clicks in PPC campaigns

As click fraud is a huge problem and one that is growing by the day, there are several steps you can take to minimise and mitigate your exposure to it. The good news is that the major search engines like Google, Bing and even Facebook, do have some strategies in place to combat ad fraud and click fraud. However their efforts are normally the minimum required.

For example, Google will track invalid clicks such as those coming from the same IP address, or those using suspicious activity. If these clicks are detected on your ad campaign you are usually automatically reimbursed. One issue is that Google treats click fraud activity with a fairly standard approach, so ten clicks from one IP address might seem odd to you, but for Google this is standard behaviour.

You can report suspicious activity to Google Ads (aka Adwords) but usually the stock answer is something along the line of, ‘this is normal customer activity’. In the cases that Google takes a deeper look at the issue, you’ll normally find it can take anything up to a month for the issue to be inspected and for your refund to come through. When you’re looking at batches of ten clicks on $10 keywords, this can run into the hundreds or even thousands.

Spotting these multiple clicks from specific sources isn’t the hard part, in fact we’ll be looking at how to spot fraudulent clicks later on in this guide. It is the increasingly sophisticated click fraud approaches that cause the biggest headaches. With software able to imitate human behaviour, switch IP addresses using VPNs and proxies, or even those click farms pulling the wool over the search engines virtual eyes, additional measures are often needed to minimise exposure to click fraud.

Using dedicated click fraud prevention software is the most effective way to make sure that you’re tackling those invalid clicks.

Is click fraud illegal?

Although it includes the term ‘fraud’ and the sums of money involved can be huge, click fraud is technically not illegal. Aspects of click fraud may be subject to certain national laws, for example the Wire Fraud Act in the USA which applies to financial fraud using telecommunications.

The act of defrauding advertisers is also one that is illegal in most countries, but the problem is policing it. Although digital crime is an area that is becoming increasingly complex, and profitable, there are few resources globally to combat it.

The short answer to the question, ‘is click fraud illegal’ is simply: No.

Clicking multiple times on your ad, creating a website with your banner placed on it and then channelling traffic though it, or hiring people to click your ad 100 times a day is all obviously highly damaging. But it isn’t illegal.

There are some cyber crime authorities who you can report activity to if you believe there is a serious and organised threat occuring. These include EuroPol, the UK’s National Crime Agency, the FBI and InterPol.

However, most of these agencies are set up to tackle more obvious cyber crime threats such as identity theft, people smuggling, drug dealing, terrorism, pornography and other more tangible problems. In the case of your competitor hiring a click farm in Pakistan to click your on your PPC campaign 100 times a day, they’re unlikely to take the situation seriously.

How can you identify click fraud?

We’ve established that click fraud is a pretty big issue, with lots of variations and the potential to really sting your cash flow. So how do you identify when you’ve been a victim of click fraud?

There are several manual checks you can do yourself to see if there has been any fraudulent activity on your ad campaigns. These don’t always give a 100% accurate reflection of what has been happening, but can serve as a useful outline and possibly flag up some of the more obvious violations.

Checking IP addresses

Google doesn’t give you the tools to check IP addresses that have visited your site, but you can use tracking tools, including WordPress plugins for IP address logging. You can also check your website visitor logs to see how many times the same IP address pops up over a specified time. If you notice that the same obscure location or IP address has been visiting your site regularly then this might be a red flag for you to try and block this IP address or location.

Google does offer some protection against multiple visits from a single IP address or device. Although it isn’t perfect and the parameters might not necessarily be what you would set yourself, it is a form of damage limitation.

Checking publishers

If you’ve been subject to one of the most popular forms of ad fraud, which is channeling your ad onto a dodgy website, then checking your publisher list will help you keep an eye on it. Look in the ‘placements’ section of your Google Ads and check the high traffic sites for any suspect activity. If you think any of them might be fraudulent you can block them from your publishers list.

A few giveaways that a site is fraudulent include pages which appear to be covered in ads, no content (or very little content of any substance) and recently registered domains.

Monitor campaign activity

Suspicious timings or spikes in engagement might be a sign that someone is targeting your ads. Especially if you seem to be getting lots of clicks and little in the way of engagement.

You might also spot a high click rate from a country that might have little to do with your market. For example if you’re a US based company and you appear to be getting lots of clicks from the Philippines but no conversions/sales, that could be a marker that you’ve been the target of a click fraud campaign.

Identifying other forms of click fraud

Aside from locations, devices, IP addresses and dodgy publishers, it can be hard to spot other forms of fraudulent traffic. Forms of fraud that mimic human behaviour or hide behind proxy servers are going to be hard for you to spot yourself. And as the processes and techniques are becoming more sophisticated, keeping track of developments and fraud can be a Herculean task. This is where using click fraud protection software comes into play and can really make a big difference.

How does fraud protection software work?

One of the main benefits of using fraud protection software is that it is constantly learning about the new threats and adapting its algorithms. When a suspect IP address, device or VPN is identified it’s then added to the list of blocked sources. So if you’re running a PPC campaign and you’re protected by software such as ClickCease you’ll be able to benefit from the ongoing process of identifying suspect sources.

How to manually block click fraud

Of course you’ll want to do everything you can to limit the amount of fraudulent clicks coming through on your ad campaign. It can be tricky and a little labour intensive to get everything battened down, but it is definitely worth doing these manual fixes.

Even if you’re not that tech savvy you’ll be able to find guides to making your PPC campaigns as watertight as you can. And where possible we have linked to the resources to help you use some of the best techniques to minimise your click fraud exposure.

Set up IP and ISP exclusions

If you’ve identified a pesky IP address that seems to be doing something strange and you’re pretty sure they’re messing up your PPC campaign you can set up some exclusions. As an IP address normally refers to a specific device or location, this can cut out fraudulent PPC activity from specific users.

We have a guide to setting up IP address exclusions.

Remarketing campaigns

If you’re not looking to boost your reach at the moment then remarketing could be a useful campaign strategy. It looks at visitors who have visited your site before and pops up on partner websites, ensuring your brand stays in their mind and possibly even encouraging repeat custom.

Of course one of the main benefits of remarketing campaigns is that you’ll only be showing up for people who have shown an interest in your business before. It should also limit your exposure to bots or click farms, especially if you’re not in their target area.

You can find out more about running remarketing campaigns on Google’s support pages.

Adjust your targeting

By tweaking your targeting for your ad campaign you can hugely reduce the exposure of your PPC campaign to fraudulent activity. Excluding certain geographic locations, languages, demographics and devices can make a big difference to the success of your advertising. If you see suspect activity coming from one particular demographic, exclude it and see what happens. You can always change it again later…

How ClickCease can help you prevent click fraud

How to automatically block click fraud

As the click fraud industry remains unchecked by controls and the profits just keep getting bigger, more and more companies are waking up to the impact that click fraud is having on their budgets. In fact, in 2019, we estimate that around 20% of the global pay per click budget will be wasted on click fraud.

By other estimates its more like 33% of the global advertising budget that is eaten by fraudulent activity every year. However you look at it, a sizeable portion of many businesses advertising budget will be wasted on fraudulent activity

By following our tips above you’ll be able to plug some of the leaks in the dam. But of course, you want to plug all the leaks and make sure nothing is getting past you. The best way to make sure you’re keeping all of your ad spend on target and not losing any to fraud is by using click fraud protection software.

Although it might seem counterintuitive to spend money on protecting your ad budget, when you consider that you could be losing hundreds of dollars a day it might make more sense as an investment.

ClickCease is a market leading click fraud protection software service that is used in over 2 million online ad campaigns. By using a sophisticated and constantly updated series of algorithms, you’ll be able to minimise your exposure to click fraud and ad fraud activity.

If you’re running Google or Bing ad campaigns then you’ll be able to prevent bot traffic and click farm activity, and minimise invalid clicks on your PPC ads. ClickCease works on all of the most popular web hosting platforms including WordPress, Wix, Shopify, Squarespace and Drupal.

Although ClickCease blocks the majority of fraudulent activity, if any activity is detected after it has happened then ClickCease can apply for a refund to Google on your behalf.

Do I really need click fraud protection software?

So do you really need to use click fraud protection software? Maybe it’s better to look at it from another angle.

Are you bidding on high value keywords? The more you pay for your average PPC then the higher your chance of being exposed to click fraud. Although losing clicks on $1 keywords might sting a little, its when you get to those $10 and up search terms that it you might start to notice a hole in your marketing budget. Your search term can include one of the expensive keywords, so for example, ‘travel insurance’ and ‘best value health insurance’ all fall under the banner of ‘insurance’.

If you’re wondering what are the most expensive keywords, and by extension, those most at risk of exposure to click fraud, these are the top 8 most expensive industries for PPC campaigns.

If your PPC keywords include some of these words then your campaign is at heightened risk of click fraud or ad fraud. As some of the PPC price can go anywhere up to $50 and over, per word, these are very attractive for fraudsters.

Even invalid and genuinely accidental clicks on these keywords can really add up to making a big dent in your marketing budget. If you do use any of these search terms, take a look at your historical adwords campaigns and see if you have been exposed to any invalid clicks.

Businesses that use any of these search terms could find that using a click fraud protection service, such as ClickCease, could boost their effective marketing spend by up to 30%.

  • Nice post. I recommend reviewing the design however – some images overlap the content.

    Also, it looks like the dynamic number counter in the section”Do I really need click fraud protection software?” is completely broken.

    Lastly, your page title is way too long. Optimize it for Google’s SERP.

  • Impressive explanation. I extremely encourage and recommend that as there is an option for preventing clicks from a specific ip addressees, a better option would be to prevent the clicks from the specific mobile or computer ex.. that would make you gain many and many more costumers, and even be one of the biggest companies.

  • I read in your guides that a device has a unique ID, regardless of whether it changes its IP or location. where can I find that ID in the application?

Block click fraud from ruining your campaign!
