Detecting click fraud that includes a server that hosts a website that includes a web page containing an advertisement. The server provides an advertisement on a web page, provides pixel clusters on the web page with the advertisement, each pixel cluster having an associated mechanism for capturing whether a cursor on the web page has transited the associated pixel cluster, and collects information based on the capturing of each associated mechanism of information regarding the transit of the pixel cluster by a cursor. The collected information is useable in a determination of a confidence level pertinent to the determination of click fraud occurring on the advertisement on the web page. The server verifies the cursor on the web page has transited at least one pixel cluster on the web page prior to a controller of the cursor clicking the advertisement.
