Textual ad impressions
Delivery of a text-based advertisement to a browser. To compensate for slow Internet connections, visitors may disable "auto load images" in their graphical browser. When they reach a page that contains an advertisement, they see a marker and the advertiser's message in text format in place of the graphical ad. Additionally, if a user has a text-only browser, only textual ads are delivered and recorded as textual ad impressions.
