Click fraud
protection

Click fraud is the deliberate clicking of paid ads with no intent to buy or convert. The two sources are click-farm services that competitors pay for (typically $50-300/month for 200-2,000 clicks per day) and botnets that monetize clicks through arbitrage ad networks. The goal is to burn your daily budget, distort campaign CTR and push up your auction CPC.

Signs: high CTR with falling conversion rate, growing share of clicks from mobile proxies and datacenter ASNs, micro-sessions of 0-3 seconds with no events, traffic spikes from regions outside your targeting, repeated clicks from the same fingerprint within an hour. In Yandex.Metrica it shows up as a rising bounce rate from the 'Direct ads' source while impressions stay flat.

Yes — both have built-in invalid-click filters and a refund process. But the filters work after the fact and miss 'high-quality' bot traffic from residential proxies. BotHunt blocks clicks on the site side and produces a report with IP, ASN, fingerprint and timestamp — you can attach it to a Yandex Direct or Google Ads support ticket to speed up the refund.

We analyse 40+ signals: TLS signature (JA3/JA4), ASN reputation, browser fingerprint (canvas, WebGL, fonts), behavioural patterns (mouse speed and curve, timings between events). A real human moves the mouse along Bezier curves at 80-400 px/s, a click bot moves in a straight line or instantly. The combination of suspicious signals delivers 99.9% accuracy with under 0.1% false positives.

Yes. BotHunt sits between traffic and the site, so it blocks fraud clicks from any source: Yandex Direct, Google Ads, VK Ads, MyTarget, Telegram Ads. The only requirement is that the landing page is behind BotHunt (via DNS or the PHP agent).

Yandex Direct catches fraud with its own algorithms and refunds the money, but it does so with a delay and misses residential proxies and high-quality botnets. BotHunt works on the site side and blocks the click the moment it tries to reach the landing page — Direct's conversion counter sees that the visit didn't happen and the campaign's behavioural profile stays clean. Two complementary layers of defence.

No. Yandex, Google and Direct validation crawlers are whitelisted by ASN and user agent. YandexBot, Googlebot and Yandex Direct validators pass through without checks. Your site stays indexable and your ads stay moderated.

The Site plan is $9/month for one site, Studio — $29/month for five. Typical recovered budget is 10-30% of monthly ad spend, so it pays for itself within a week on any campaign over $300/month. 14-day free trial, no credit card required.
