Systems and methods for determining advertising activity
摘要:
A system may provide an advertising link in association with a document. The content of the advertising link is unrelated to a content of the document. The system may also determine a rate at which the advertising link is selected and determine whether illegitimate activity occurred based, at least in part, on the determined rate of selection.
