In fighting fraud, it’s important to monitor not just IPs, but also devices sending ad clicks. Some of them act oddly, not like real users.
Signs of a suspicious device:
- same user-agent across thousands of sessions;
- abnormal screen size (too small or too large);
- strange resolution not matching known devices;
- clicks without any interaction (no scroll, no mouse);
- night-only or timer-based activity.
Why it’s harmful:
- you waste money on fake impressions;
- your analytics become unreliable;
- ad platforms consider them valid and increase exposure.
What to do:
- Use AntiClick to track and label devices.
- Filter by resolution, activity, and behavior.
- Block by user-agent or IP groupings.
- Clean reports to reflect verified users only.
