Online advertisements may be verified before being rendered. In one example, an ad control is incorporated into an application or web page. When the ad control is to present an ad, the ad control requests an ad from an ad provider. Upon receipt of the ad, the ad control generates one or more hashes from the ad, and may extract one or more landing pages from the ad. The ad control then submits the one or more hashes, and the URLs of the one or more landing pages, to a reputation service for verification. The reputation service may then determine whether the ad and/or its landing pages are acceptable, and returns an“OK”or“not OK”message accordingly. If the ad and its landing pages are determined to be acceptable, then the ad control renders the ad. Otherwise, the ad control requests a new ad from the ad provider. |
