What is an ad tag?

An ad tag is a small piece of code that is placed on a website, mobile app, or other online platform in order to display an advertisement. Ad tags are used by advertisers to target specific audiences and track the performance of their ads. They enable advertisers to deliver digital ads to specific locations and demographics, as well as to manage ad campaigns across multiple platforms. Ad tags typically include details such as the ad size, placement, and targeting parameters. They can be served through a variety of ad platforms, including Google Ad Manager, DoubleClick for Publishers, and AdSense. Ad tags are an important part of the digital advertising ecosystem, enabling advertisers to deliver targeted, relevant ads to their audience.
