Definition of ad tags in advertising

An ad tag, also known as an ad placement tag, is a snippet of HTML or JavaScript code that an advertiser provides to a publisher to display an advertisement on a webpage or app. The ad tag calls the ad server to fetch the ad creative and display it in the designated ad slot. It also facilitates tracking and reporting on ad performance.


Ad tags are essential for serving digital advertisements and collecting data on ad impressions, clicks, and other interactions. They enable advertisers and publishers to manage and monitor ad campaigns effectively.
