Companies Using Spider AF

Spider AF is a Japanese ad-fraud tool, and its tag is easy to read. Advertisers install a snippet that calls sptrk('config', ...) with an account id, and the visit report goes to sp-trk.com under that id. After cleaning, our October 2026 crawl finds 1,594 live domains, 12th of 32 in the category. Reading the accounts is also what forced the cleaning, so I'll start there.

Whose tag is it?

The tag reaches pages from two addresses. sp-trk.com is the advertiser's own install. sp-gn.com is a second loader, and the two never overlap: 166 domains load only sp-gn.com. They are publishers, Japanese and Indonesian news sites, blogs and forums, and 120 of the 140 I fetched carry Geniee's ad tag. Geniee, the Tokyo ad platform, announced in December 2022 that its DSP would use Spider AF's IP blocklist. None of the 25 such pages that rendered in our browser loaded Spider AF, which fits a tag that arrives with Geniee's ads rather than with the site. Those 166 domains, 9.43% of the 1,760 left after title filtering, aren't Spider AF customers, and we removed them from every count on this page.

Sales signal: if you build a Spider AF list from raw tag data elsewhere, drop publisher and news domains first. A Japanese news site carrying the tag is usually a Geniee publisher, not an advertiser that bought fraud protection.

Accounts behind the advertisers

On the other side, I could read the account id on 1,142 domains, from the page itself or from the site's Google Tag Manager container, and they belong to 877 accounts, about 1.3 domains each; 698 accounts sit on one domain. The large accounts are single businesses: 28 domains of a knee-joint and cosmetic clinic group, 13 sites for Brillia-branded condominium developments, 11 osteopathic clinics and 10 wedding-photo studios. One account looks like an agency's, covering 18 unrelated brands from Iittala and Arabia's Japanese store to Dr.stretch. To test the tag, I opened 60 random advertiser domains: 54 rendered and 45 sent Spider AF's visit report, and two more carried the tag in Google Tag Manager.

Sales signal: roughly 900 accounts is the real prospect count, and most of them actively report traffic: 45 of the 54 sampled pages that rendered.

Reading the trend

The chart shows a single October reading, because the cleaned count starts there; earlier monthly totals included the Geniee pages. Those totals also moved with our crawl: the set of domains we crawl turns over every month, and the signals we detect Spider AF with have widened, so I wouldn't read them as adoption anyway. Exits are low: 135 domains dropped Spider AF on at least one hostname since 4 August 2026, and about 49 of them still run it on another hostname.

"Spider AF's list reads like a Japanese marketing department's: recruiters, housebuilders, education groups. These buyers pay for leads as well as clicks, and they protect both." - Emma Davies, Data Analyst at TechnologyChecker.io

Sales signal: low churn means few switching windows. Target new advertisers in the same verticals rather than waiting for these to leave.

Who buys it

Spider AF's buyers are bigger than the click-fraud norm. 88 of the 387 matched companies with a known size have more than 200 staff, against under 4% at Fraud Blocker. Bridgestone runs it on its tyre store, Sekisui House on its owners' portal, Benesse on its corporate site and freee on its main site. Recruitment stands out: about one in five of the 50 companies on our list are staffing or HR firms, from JAC Recruitment to SmartRecruiters. Founding years are older too, with 37.71% in the 2010s and only 8.05% in the 2020s. Spider Labs' about page claims more than 600 companies protected as of May 2026; on the domains we could check, we read 877 account ids.

Sales signal: sell to the marketing or recruitment-marketing team of a mid-sized company. These buyers have budgets and procurement, so a $150-a-month tool is a line item, not a gamble.

Japan and Singapore

Japan has 248 of the 444 matched companies and Singapore 99; the United States has 39 and no other country reaches ten. Singapore's count is spread across separate accounts: banks (RHB), schools (Kinderland, Seriously Addictive Maths), attractions (Science Centre Singapore, Timezone) and clinics. Retail leads the industry data at 8%, and no industry goes above it.

Sales signal: Singapore is the best English-language list here. For anything sold to performance marketers in Southeast Asia, these 99 organisations already pay for traffic verification.

Next to ClickCease

We have no switching flow to report. 52 domains run Spider AF and ClickCease today, of 57 ever seen with both, so where they meet, advertisers keep both. ClickCease is 33,001 domains to Spider AF's 1,594, but it serves a different market.

"When 52 of the 57 sites that ever ran both tags still run both, nobody is switching. These advertisers want a second opinion on their traffic." - Emma Davies, Data Analyst at TechnologyChecker.io

Sales signal: the 52 dual-tag sites spend enough on ads to pay for two fraud tools, which makes them prime prospects for anything that cuts wasted ad spend.

The stack around it

On the 1,597 domains behind our stack figures, Google Analytics runs on 98.43%, DoubleClick Floodlight on 72.7%, Yahoo Advertising on 56.61% and Microsoft Advertising on 47.65%. Intimate Merger (24.05%) and Criteo (22.17%) point to Japanese audience data and retargeting. WordPress carries 37.07%, and Shopify only 5.57%.

Sales signal: advertisers on Yahoo's network are the core. Agencies and tools that manage Yahoo and Google search side by side will find most of their market here.

What it costs

Spider AF's pricing page, read on 15 October 2026, lists Performance at $150 a month billed monthly, or $120 billed annually, for up to 50,000 clicks, Elite at $990 or $790 for up to 150,000, and custom Enterprise pricing above a million clicks, with a 14-day free trial. That starting price is about twice Fraud Blocker's $79.

Key takeaways

• 1,594 live domains once 166 Geniee publisher pages are removed.
• About 900 advertiser accounts; 45 of 54 sampled sites were actively reporting.
• Japan (248) and Singapore (99) hold most matched companies.
• Larger buyers than most click-fraud tools: 88 of 387 sized companies have over 200 staff.
• Recruiters, housebuilders and education groups stand out.
