Criminals are stealing your advertising budget.

And amost everyone is looking the other way.

Marketers are focused on KPIs, not bots.

Marketers have milestones to reach, such as the number of website visitors and leads. Blocking bots is not a priority, since bots make it easier to hit KPIs. By adding Polygraph to your website, you add marketing transparency and ensure your advertising budget is spent on real visitors.

Ad networks are focused on traffic, not bots.

Ad networks have a financial incentive to allow both humans and bots to click on ads, since they get paid for every click, real or fake. Polygraph retrains the ad networks' traffic algorithms to stop showing your ads to bots, and protects your advertising spend from click fraud.

Increase marketing effectiveness with a bot blocker.

Based on our audit data, we can estimate 8-20% of your ad clicks are from bots. Block them to save money without losing real customers.

CAPTCHA alone isn’t enough.

Today's bots use human-like behavior to bypass CAPTCHAs and submit fake leads. Blocking IP addresses doesn't work either. Polygraph detects even the most advanced click fraud bots, and prevents them from submitting fake leads.
