The short answer
In 2026, across a sample of 1,900+ websites and ~198 million visits on the ClickCease network, roughly 22% of analyzed traffic was invalid – bots, automated agents, and other non-genuine visitors. The rate varies sharply by industry: B2B services, technology, education, real estate, and financial services see the highest invalid rates, while entertainment and consumer services sit lower. The lead-generation verticals – law firms, insurance, home services – are hit hardest of all.
TL;DR
- In 2026, about 22% of analyzed traffic across this ClickCease-network sample was invalid; the typical (median) site saw 17%.
- 43% of sites had more than a fifth of their traffic flagged invalid, and 11% had more than half.
- The hardest-hit verticals are lead-gen heavy: law firms (~32%), insurance (~30%), real estate (~29%), roofing and plumbing (~27%).
- 2026’s traffic mix has been reshaped by AI – Google’s AI Overviews and a surge in automated AI agents – a likely contributor to elevated invalid rates.
- In lead-gen industries, invalid traffic doesn’t just skew analytics – it becomes fake leads in the CRM, which is where it costs the most.
Every marketing team knows some of their traffic isn’t real. What most don’t know is how much – or how sharply it differs depending on the industry they’re in. To put real numbers behind it, we looked at aggregated invalid-traffic data across the ClickCease network in 2026: 1,900+ websites, 1,000+ accounts, and roughly 198 million visits, grouped by industry. No individual site or account is identified; every figure below is an aggregate.
The headline is stark. Across the sample, about 22% of analyzed traffic was invalid – flagged as bots, automated agents, or other non-genuine activity. But the average hides the real story, which is how unevenly that invalid traffic is distributed.
How much traffic is actually fake?
Invalid traffic isn’t a rounding error you can ignore. In this dataset, the median website saw 17% of its traffic flagged invalid, and the distribution has a long, ugly tail:
That tail is the real story. Invalid traffic isn’t spread evenly – a minority of sites carry the bulk of it, and which side of the line you land on depends heavily on the industry you’re in.
Fake traffic by industry: the 2026 benchmark
Grouped into broad categories, the differences are clear. Business-to-business, technology, education, and finance sit well above the network average; consumer-facing entertainment and retail sit below it. Here’s the share of traffic flagged invalid by category:
Share of analyzed traffic flagged invalid, by category (traffic-weighted). ClickCease network sample, 2026.
The split isn’t random. The categories at the top share a common trait: they run on leads, not transactions. A B2B software company, a law firm, or an insurance broker doesn’t sell at checkout – it captures a form fill and follows up. That makes their traffic a more attractive target, because invalid activity that produces a fake lead can waste far more than a single visit.
The verticals hit hardest
Drilling into specific industries (showing those with a robust sample of sites) sharpens the picture. These are the verticals where invalid traffic bites hardest:
| Industry | Invalid traffic (weighted) | Typical site (median) |
|---|---|---|
| Law firms | 32% | 27% |
| Insurance / brokerage | 30% | 15% |
| Real estate | 29% | 14% |
| Roofing contractors | 27% | 18% |
| Plumbing | 27% | 19% |
| Software / SaaS | 21% | 24% |
| HVAC services | 16% | 24% |
Law firms top the list at roughly a third of all traffic flagged invalid – and unlike categories where one big site skews the average, law firms show a high median too (27%), meaning the typical firm is genuinely swamped. It’s not hard to see why: a single legal lead can be worth thousands, which makes law firms a prime target for the bots, scrapers, and lead-selling schemes that chase high-value verticals.
⚠️ The lead-gen tax
The industries at the top of this list all sell through lead capture, not checkout. For them, invalid traffic doesn’t just skew analytics – it produces fake form submissions that reach the CRM, trigger automated follow-up, and send teams chasing prospects who were never real. That’s the problem Lead Shield is built for: it scores every form submission before it reaches your CRM, so invalid traffic never becomes a fake lead.
Why 2026 looks different: AI Overviews and automated traffic
Invalid traffic isn’t new, but 2026 is a different environment than even a year ago – and two shifts stand out.
First, Google’s AI Overviews and AI-driven search have changed how people, and machines, reach websites. More queries are now answered directly on the results page, which reshapes who clicks through and why. At the same time, a fast-growing share of the visits that do land on sites come from automated AI agents rather than humans – crawling, summarizing, and interacting with pages at machine scale. Second, the tools to generate convincing automated traffic are cheaper and more capable than they’ve ever been.
This is a point-in-time snapshot, so it can’t prove what caused any single site’s rate. But the backdrop matters: as more of the web’s activity becomes automated, the share of traffic that isn’t a real human rises with it – and the information-heavy, lead-generation verticals at the top of this list are exactly where that automated traffic tends to concentrate. If your invalid rate looks higher than it did a year ago, the shifting 2026 traffic mix is a likely part of the reason.

What you can do about it
The goal isn’t zero – some invalid traffic is unavoidable – but if your rate is well above your category’s average, there’s real damage being done to your data and your pipeline. A few practical steps:
- Measure your real invalid rate. Standard analytics dashboards don’t surface it, so most teams have never seen their true number. You can’t fix what you can’t see.
- Block invalid and automated visitors in real time, before they interact with your site.
- Screen your forms. In the lead-gen verticals at the top of this list, scoring every submission before it reaches your CRM is the single biggest lever – it’s exactly what Lead Shield does.
- Keep your analytics clean, so bot and automated traffic isn’t quietly skewing the metrics you make decisions on.

Methodology: Figures are based on aggregated invalid-traffic data from a sample of 1,900+ websites across 1,000+ accounts on the ClickCease network (part of CHEQ), representing approximately 198 million visits in 2026. All figures are aggregated by industry; no individual account or website is identified. “Invalid traffic” refers to visits identified and flagged as invalid or non-genuine by CHEQ’s detection engine. Category and industry rates are traffic-weighted (total invalid events divided by total events); “typical site” figures are medians across sites. Industry-level figures shown reflect verticals with a sufficient sample of sites.
