Contextual advertisements embedded within content having tooltip type display functionality are provided where content can be evaluated for possible points for insertion of the advertisements. The content can be evaluated against a list of trigger points indicating advertisement should be inserted along with instructions to embed the advertisements. Using this information, the content can be modified to embed appropriate advertising. Upon returning the content, a viewer thereof can view the content normally, but certain events with respect to the trigger points can cause tooltip type display of the advertisement (such as hovering a cursor over the trigger point). In this regard, trigger points, such as keywords, having associated pop-up advertisements can be underlined or otherwise identified.
