Note: Mobile app remarketing does not yet support dynamic ads.
Tagging your website
Place the Google remarketing tag on all pages of your website. To get started, you'll need to place the remarketing tag on all the pages on your website. You can also find the code in the Shared Library section of your AdWords account.
To ensure that all the webpages on your site include the remarketing tag, you should insert the remarketing tag in one place, where it would automatically update all the webpages on your site. Typically you would do this within your webpage template.
Use tag validations tools to ensure proper implementation. Review whether the tag was properly implemented by using the recommended tag tools:
• Get the Tag Assistant Chrome Extension to verify that you've installed the remarketing tag correctly. Once installed, you can just navigate to any page of your website to see which tags are on the page. Tag assistant will also tell you if there are errors to the tag and offer suggestions on how to fix it. More information about tag assistant
• Tag Validation in AdWords allows you to see whether your remarketing tag is properly firing, provides useful statistics on your remarketing tag, and shows you common solutions to help troubleshoot in the event of a problem. More information about tag validation
If you've already created a remarketing campaign, the lists that are available in your campaign will start getting visitors or users added to them. You can also create new lists as needed.
