Click Fraud

Detailed explanation

Click fraud takes a few common forms: competitors manually or automatically clicking a rival's ads to burn through their daily budget, publishers or affiliates using bots or paid click farms to inflate their own ad revenue, and automated scripts clicking ads with no genuine interest in the product at all. In every case, the advertiser pays for a click, in a CPC model, that could never have converted.

Platforms like Google Ads run automated invalid-click detection that filters out much of this traffic before it is ever billed, and advertisers have additional tools available: IP exclusion lists, geographic and device targeting to cut off suspicious traffic patterns, and manual monitoring of metrics like an unusually high click volume with an unusually low conversion rate from a specific placement or region. Persistent unexplained spikes in cost with no matching lift in conversions are the clearest warning sign worth investigating.
