Tag your pages with GPT

Now that you've created your first ad unit, it’s time to start serving ads. To do so, you'll need to insert Google Publisher Tags (GPT) on your webpage to request and display ads from Ad Manager. Google Publisher Tags are snippets of code you add to your webpage to request an ad from Ad Manager. These tags send browser, location and other anonymous information about the user as well as targeting you define such as ad units or key-values.

Choose the best inventory ad tag

Google Publisher Tags offer flexibility to accommodate different content loading techniques (asynchronous or synchronous) as well as an option to request all of a page's ads at one time, or separately. Learn more

  • Choose how your content and ads load together on a page
    GPT can load ads independently from content in separate iframes with the asynchronous tag option, or directly alongside content with the synchronous option. We generally recommend using the asynchronous GPT option as it often decreases a site's page load time by allowing the rest of your content to load while the ad is loading. The synchronous GPT option can provide greater flexibility for expandable ads or other creatives that do not display correctly in an iframe.
  • Request all of a page's ads at once, instead of using multiple tag requests
    GPT single-request mode can enhance page load performance and help roadblock creatives.
You can use different tag options on different pages of your website, but you shouldn’t mix options on the same page.

Generate your ad tags

Generate Google Publisher Tags and work with your development team to insert the tags into your content.

A few things to keep in mind:

  • It can take up to 30 minutes after tagging your pages with GPT before you see Google AdSense ads trafficked through your Ad Manager network. 
  • Only request ads you intend to display on the page. If you request ads, but never display them, your reporting is likely to be negatively affected.
  • Insert Google Publisher Tags on your page before you plan to fully launch Ad Manager ad serving for your content. This allows Ad Manager to build a forecasting profile for your content. Learn more
