Ads are short for advertisements. Businesses or individuals trying to market products or services often create ads to drive their promotion efforts. Ads appear in a channel, such as YouTube, Google search results, inside apps, on websites, and almost anywhere there is available real estate. The advertiser pays a fee to the content publisher, such as a website owner, search engine, or app developer, in order to rent that real estate for the purposes of advertising.
While print ads often run for a flat fee, online advertisements are usually cost-per-click or cost-per-mille, i.e., cost per thousand impressions. Advertising revenue is not based on whether the user actually buys something, unlike affiliate marketing, which typically pays out only when the user makes a purchase.« Back to Glossary Index
