Determining Suspicious Advertisements By Comparing Advertisement Content And Content Associated With An Advertisement Landing Page

摘要

A online system receives advertisement (“ad”) requests for presentation to online system users, with each ad request including advertisement content and identifying a landing page. The online system determines whether the advertisement content differs from content associated with a landing page identified by an ad request. One or more topics associated with the advertisement content are identified, as well as one or more topics associated with content on the landing page. By comparing topics associated with the advertisement content to topics associated with the landing page content, the online system determines if the advertisement content and landing page content differ. If the advertisement content differs from the landing page content, the online system may prevent the ad request from being presented or may identify the ad request for manual review.
