What is Click Fraud?
Click fraud is deliberate or automated inflation of paid ad clicks without genuine user interest in the product. Motives include draining a competitor's budget, inflating publisher CTR, or billing for fake traffic. It distorts CPC, auction quality, and media buyer reporting.
Common forms
- Bots and scripts — automated clicks from datacenter IPs.
- Click farms — humans or emulators clicking ads at scale.
- Competitive drain — targeted clicks on rival ads.
- Publisher fraud — inventory inflating clicks in push/native networks.
vs bot traffic and invalid traffic
Bot traffic includes crawlers and prefetch—not always malicious. Click fraud targets billable clicks meant to cheat billing. Platforms (Google, Meta) filter some as invalid and do not charge; the remainder skews CR and ROI in the tracker.
Defense
Ad-platform filters, landing-page device fingerprinting, datacenter ASN blocks, CTR vs CR analysis by sub id. CPA networks may accuse affiliates of click fraud on anomalies—transparent tracking and source whitelists reduce risk.
