Google Publisher Tag (GPT)

Google Publisher Tag (GPT) is an ad tagging library for display ads, which allows you to dynamically build ad requests.

  • Create passback tag: Use in any situation where an ad request to a third-party should ultimately be filled by an ad trafficked in your network. Learn more about Google Publisher Tag (GPT) passback functionality.
  • Single request: Single request architecture (SRA) means that instead of sending individual ad requests to Ad Manager servers, the browser is able to send one request notifying the server of all ad units on the page. This activates guaranteed roadblocking. Learn more about SRA requests.
  • Collapse empty divs: If you know that the ad slot is rarely filled, you can instruct the browser to collapse empty divs. Learn more about collapsing empty divs.
  • Page-level key-values: Set custom attributes across all ad slots on the page to use less code and ensure ad slots have the same targeting attributes. Learn more about key-values.
  • Out-of-page creatives: Select whether the tag is for an out-of-page creative. Learn more about out-of-page creatives.
  • Sizes: Select the inventory sizes for the tag. You can see applicable size options by clicking into this field. More than one size may be available. This is not applicable to out-of-page creatives.
