Retargeting is one of the most powerful ad strategies. But if your audience list is polluted with fraudulent visits, your budget is wasted on bots — not buyers.
How fraud enters retargeting lists:
- bots trigger the Google Ads pixel;
- click farms open landing pages with no engagement;
- VPN or proxy visits look unique but aren’t real.
What happens next:
- ads are shown to non-human visitors;
- you pay for impressions and clicks with zero return;
- conversions drop, cost per action rises;
- algorithms “learn” from bots, not buyers.
How to clean your retargeting:
- Use AntiClick to filter out suspicious visits.
- Refresh audiences with only real user activity.
- Exclude IPs with repeat fake sessions.
- Segment and compare ad performance by behavior.
