Companies Using Fraud Blocker

Fraud Blocker is an easy product to count and a slightly harder one to read. A domain counts here when a page loads its script from monitor.fraudblocker.com, and that address carries the advertiser's account id, so I can group sites by buyer as well as count them. Our October 2026 crawl finds 5,113 live domains, 6th of the 32 technologies in Fraud Prevention. Here's what I found, and what it means for a seller.

Is the script doing anything?

I opened 60 random live domains in a browser. 35 rendered for us, and on 25 of those 35 the script loaded and sent its follow-up check calls before we closed the page. Six of the other ten still carried the tag, either in the page or in their Google Tag Manager container, and it didn't fire in our short visit. One had removed it and three were behind a Cloudflare error or challenge. So the signal is working installs, with a small tail of stale tags that our monthly recrawls will clear.

Sales signal: a Fraud Blocker domain is usually an advertiser with live paid traffic, because advertisers don't pay to screen clicks they aren't buying. That makes the list a ready-made filter for anything sold to active PPC spenders.

Accounts behind the domains

On the 4,057 domains where the script address shows an account id, I count 3,287 accounts, about 1.23 domains each, and 2,857 accounts sit on a single domain. No platform or reseller runs one account across unrelated sites at any size that matters. The multi-domain accounts are mostly one company each: 31 keyword domains of Klein Epstein Parker, a bespoke-suit maker; 23 of Weening Strafrechtadvocaten, a Dutch criminal-law firm; and the domains of firms Saltus (14) and Savant Wealth (13) acquired, which now forward to the buyer. One account is different. Raymond, the forklift maker, loads the same id on raymondcorp.com and on 18 domains in total, most of them Raymond dealers such as Carolina Handling and Pengate Handling Systems.

Sales signal: treat the list as roughly 3,300 buying decisions, and sell to Raymond's marketing team once rather than to each dealer.

Reading the trend

The chart climbs from 4,199 domains in June to 5,113 in October. I wouldn't call that growth. The set of domains we crawl turns over every month, with dead sites leaving and new ones arriving, and the signals we detect Fraud Blocker with have widened. What I can measure is exit: 948 domains dropped Fraud Blocker on at least one hostname since we began tracking removals on 16 March 2026, and about 140 of those still run it on another hostname.

"A click-fraud tag is only worth paying for while the ads run. When I see one disappear, my first question is whether the campaign stopped, not whether the advertiser changed vendor." - Emma Davies, Data Analyst at TechnologyChecker.io

Sales signal: before pitching a rival tool to a domain that dropped Fraud Blocker, check whether its ad tags are still live. If they aren't, the timing is wrong.

Who buys it

55.0% of matched companies with a known size have 1 to 10 employees and 31.1% have 11 to 50, so 86.1% have 50 or fewer staff, slightly more than ClickCease's 83.21% on its own profile. Only 46 have more than 500 staff. The bigger names run it on their main site: Raymond, Weston Solutions, MIDFLORIDA Credit Union, Keppel Data Centres. Founding years skew recent, with 40.71% founded in the 2010s and 15.26% in the 2020s. Fraud Blocker's own about page says it was founded in 2019 and claims 4,500 client accounts, which sits close to the 3,287 accounts I can read.

Sales signal: pitch the person who owns the ad account, often a founder, an office manager or an outside agency. Talk about cost per lead.

Which trades and countries

Construction leads at 7.63%, then retail (5.45%), medical practices (4.94%) and advertising services (4.33%). No industry passes 8%. What these buyers share is a high price per click. Education is a cluster worth noticing: eight of the 50 companies in our list are colleges or schools, from John Carroll University to Tabor Academy, all buying enrolment clicks. The United States has 1,510 of the 3,346 matched companies, then Australia (315), Canada (261) and the United Kingdom (217). Australia and New Zealand together (404) outnumber Canada.

Sales signal: Australian and New Zealand advertisers are over-represented here relative to the usual US-tool order, so anything sold to PPC buyers in that region has a list to start from.

Next to ClickCease

ClickCease is the direct rival, with 33,001 domains in the same crawl, about six and a half times Fraud Blocker's count. We don't publish a switching flow between them, because they are stacked more than swapped: 217 domains run both scripts today, out of 284 ever seen with both. From tags alone I can't tell a side-by-side trial from a second script left behind. The smaller PPC tools, ClickGUARD (1,471) and Spider AF (1,594), are far behind both.

Sales signal: the 217 dual-tag domains are paying, or trialling, twice for one job. Whichever vendor shows more blocked spend in a month probably keeps them.

The stack around it

Of the 5,098 domains behind our charts, Google Analytics runs on 92.02% and DoubleClick Floodlight on 47.65%. WordPress carries 62.5% and Elementor 28.99%, while WooCommerce (9.3%) and Shopify (8.63%) are minor. These are lead-generation sites. Microsoft Advertising's tag appears on only 14.83%, which fits a vendor whose pricing page promises Google, Facebook and Instagram protection and leaves Bing Ads to an export of blocked IP addresses.

Sales signal: WordPress and Elementor agencies, form-spam tools and call-tracking vendors fit this list better than ecommerce apps do.

What it costs

Fraud Blocker's pricing page, read on 15 October 2026, lists Starter at $79 a month for 5,000 ad clicks on one website, Pro at $99 for 25,000 clicks on up to 50 websites, and Enterprise from $489 for 250,000 clicks. Quarterly and annual billing cut those prices, and there's a 7-day free trial. ClickCease's pricing page lists its Starter plan at $99 a month after a discounted first three months, so Fraud Blocker is the cheaper first step.

Sales signal: the Pro plan's 50-website allowance is built for agencies, and advertising services is the fourth-largest industry here. An agency already managing click fraud for its clients can carry your product to all of them.

Key takeaways

• 5,113 live domains, about 3,300 accounts: count buyers, not hostnames.
• 86.1% of matched companies have 50 or fewer staff; the buyer owns the ad account.
• Construction, clinics, colleges and agencies lead, all paying a lot per click.
• ClickCease is about six and a half times larger, and 217 domains run both.
• The stack is WordPress lead-gen, Google-first, with little Microsoft Advertising.

Sales applications

Outreach template: "You already pay Fraud Blocker to stop wasted clicks on your Google ads. We help advertisers like you [turn the clicks that remain into booked jobs]." Keep it about ad spend and leads.

Targeting strategy: on TechnologyChecker.io, filter Fraud Blocker users to construction, medical practices and higher education with 1 to 50 staff, then group by account so a forklift dealer network or a wealth group counts once.

Competitive angle: for ClickCease's team, the 217 dual-tag domains are the shortlist; for Fraud Blocker's, the same list is a retention risk.

Fraud Blocker users can be filtered alongside the rest of the Fraud Prevention category on TechnologyChecker.io, covering 5,113 domains and 3,346 matched companies as of October 2026.
