How bots end up clicking your ads
Bots reach paid ads for several reasons: crude click bots hired to drain a competitor, automated fraud rings monetising ad networks, and scrapers that trip your ads while crawling. To Google's basic filters and to your reports, many of these look like ordinary clicks — so they get charged to you.
How to tell a bot from a buyer
- It comes from a server. Bot traffic overwhelmingly originates from datacenters, hosting and VPN networks — not homes or mobile carriers.
- It moves too fast, or not at all. Machine-gun click timing, or a landing with zero human movement, both give it away.
- It repeats. The same fingerprint across many IPs is automation, not a crowd.
Blocking bot clicks with ClickSheriff
ClickSheriff was built for exactly this. Its full datacenter and ASN database identifies traffic from the networks bots actually use, in well under a millisecond per lookup. Free, it flags every bot click and shows you the network behind it. In Pro, cloaking hides your ad from those networks in real time and honeypot traps catch scripted clickers that try to look human. The result: the bots keep clicking into a wall instead of into your budget.
