An ad placement system provides functionality for users to rate advertisers associated with particular ads they view, and/or to rate particular ads. The ratings supplied by individual users in association with a given advertiser are used by the system to generate an average or other aggregate rating for the advertiser. This aggregate rating is exposed to users in association with the advertiser's ad or ads, allowing users to efficiently take the advertiser's reputation into consideration in deciding whether to click through or otherwise select such ads to access the advertiser's web page or site. For example, in one embodiment, each ad is displayed with a corresponding visual indication of the aggregate rating of the advertiser.
