Competitor Click Fraud: How Rivals Drain Your Google Ads Budget

· 6 min read · Updated: August 14, 2026

Competitors can deliberately click your ads to burn daily budget. Signs, evidence and automated protection.

What is competitor clicking?

Competitor click fraud is when rival businesses (or people acting for them) click your Google Ads on purpose to exhaust your budget so their ads get more share of voice.

It often looks “human” — no classic bot signature — but repeating patterns give it away.

How to spot it

Manual defense is not enough

Excluding IPs in Google Ads helps, but rivals rotate IPs, use VPNs or leave office networks. Manual lists always lag. Automated scoring + exclusion sync cuts the pattern as soon as it repeats.

Protection with TOK Shield

TOK Shield scores repeating IPs, short sessions and campaign concentration. Over-threshold IPs sync to Google Ads exclusions. See why each IP was blocked and allowlist if needed.
