Tag your website using Google Ads

To provide a comprehensive and consolidated view of your Audiences and make audience management and optimization simpler, you’ll see the following improvements in Google Ads:

  • New audience reporting
    Detailed reporting about audience demographics, segments, and exclusions is now consolidated in one place, the “Audiences” tab within the left page navigation menu. You can also easily manage your Audiences from this report page. Learn more About Audience reporting
  • New terms
    We’re using new terms on your audience report and throughout Google Ads. For example, “audience types” (these include similar, custom, in-market, and affinity) are now referred to as audience segments and “remarketing” is now referred to as “your data”.

Tag your website with the global site tag to set up an audience source in your website or apps that helps you reach people who have visited your website or who have used your app. The global site tag is a web tagging library for Google's site measurement, conversion tracking, and products using your data segments. It’s a block of code that adds your website visitors to your data segments, allowing you to target your ads to these visitors.

For dynamic remarketing, you’ll also use event snippets, which passes specific data to Google Ads about your website visitors and the actions that they take on your site.

This article contains instructions for how to set up tracking using global site tag, including using snippets for tracking. You can skip to one of the following sections:

Additionally, learn how to tag your site for dynamic remarketing or how to set up your app for dynamic remarketing.

Before you begin

  • You need to be familiar with your website's code. Otherwise consider working with a developer or someone with a technical background.
  • Your data segments that are comprised of your website visitors and app users need to have a minimum number of visitors in order for your ads to show.
  • Once you tag your website, people visiting your website will be automatically added to your data segments based on the rules you've set.
Google Ads does not permit the implementation of tags on pages related to policy-restricted offers. Learn more about the Personalized advertising policy

Instructions

Setting up remarketing for the first time with the Google Ads tag

To set up website remarketing for the first time in Google Ads, you'll need to add a code snippet to your website: the global site tag and the optional event snippet.

Once you’ve installed the global site tag, it will capture information about the pages viewed by your website visitors. This information includes the page URL and title, and is used to create remarketing lists.

You must install the global site tag on every page of your website, but you need only one global site tag for each Google Ads account.

Setting up event snippets

The event snippet can be used to pass specific data to Google Ads about your website visitors and the actions they take on your site, such as viewing a product, completing purchases, filling out online forms, and setting up registration. The data passed to the event snippet can be used to create dynamic remarketing lists as well.

You can also use the event snippet to measure additional actions that should be counted as dynamic remarketing events. Install this snippet on site pages you'd like to measure, where the event occurs. These events include when a customer makes a purchase on a retail site, or searching for airline tickets on a travel site. Learn more about event parameters for different business types

Please ensure you're providing users with clear and comprehensive information about data collection, and obtaining consent where legally required.

Create or edit your global site tag and remarketing event snippet

  1. Sign in to Google Ads.
  2. Click on the tools icon Google Ads | tools [Icon] in the upper right and click Audience Manager under the section labeled “Shared library”.
  3. On the left, click Audience sources. This opens a group of sources from which you can create remarketing lists.
  4. In the “Google Ads tag” card, click SET UP TAG.
    • If you’ve already set up a tag, select Edit source from the 3-dot icon 3 dot icon in the upper right of the “Google Ads tag” card. If you’re just getting the code, skip to step 6.
  5. Select which type of data the tag will collect, standard remarketing data or dynamic remarketing data, which includes specific attributes/parameters.
    • You can also choose to include the user ID parameter with the tag. Including the user ID parameter allows you to pass a user ID to the tag for each website visitor, which enables features like cross-device linking.
    • If you select specific attributes or parameters, you can choose the business type that best represents your products and services.
  6. Click CREATE AND CONTINUE.
    • This button will say SAVE AND CONTINUE for an existing tag.
  7. When the installation screen appears, your global site tag and event snippet will be ready for use. You can copy the code, use Tag Manager, download the tag, or email the tag to a web developer.
    • To integrate remarketing into your site, copy the code and paste it between the <head></head> tags of the website.
      Alert: The event snippet should not be copied and pasted as-is for use on your website. It contains placeholder values that your web developer must dynamically populate when they integrate the snippet code into their web server. Learn how to use event parameters for your business type
    • The global site tag must be added into every page of your site. Whereas the event snippet only needs to be added into the specific pages you want to track for dynamic remarketing events.
      Note: If you have already set up the global site tag using Display & Video 360, Search Ads 360, Campaign Manager 360, Google Analytics or another Google Ads account, it isn’t necessary to add it to your website again. However, for both conversion tracking and remarketing to work, you’ll be required to add the config command (a piece of code that contains your conversion ID) to every instance of the global site tag right above the </script> end tag. In the following example, “AW-CONVERSION_ID” stands for your account’s conversion ID:

      gtag('config', 'AW-CONVERSION_ID');

      If you have the global site tag implemented from products other than those listed above, it needs to be customized to enable measurement with Google Ads. If you are using the old event snippet, you may be prompted to change to the new event snippet, which is recommended.

  8. Click DONE.
  9. In the following “What’s Next” confirmation screen, click DONE again.
    • Optional: If you previously added the global site tag from another Google product such as Google Analytics, make sure you add the 'config' command from the Google Ads tag (highlighted below) to every existing instance of the tag. Note that "AW-123456789" is only an example of an ID. You'll need to replace this part of the 'config' command with your accounts' conversion ID in the global site tag box.
          <script async src="https://www.googletagmanager.com/gtag/js?id=AW-123456789"> </script>
          <script>
          window.dataLayer = window.dataLayer | | [ ] ;
          function gtag ( ) {dataLayer.push (arguments ) ; }
          gtag ('js' , new Date ( ) ) ;
          gtag ('config', 'AW-123456789') ;
          </script>

Using the Google Analytics tag in place of the Google Ads tag

To use your Google Analytics tag instead of the Google Ads remarketing tag, you’ll need to have the following:

  • Google Analytics tag on your website
  • Linked Google Ads and Google Analytics accounts (when linking your accounts, you'll need administrative access to the Google Ads account and edit access to the Google Analytics account)
  • Remarketing and advertising features enabled in Google Analytics

For detailed instructions, see Enable remarketing and advertising reporting features in Google Analytics.

Advanced options

Disable the collection of your data

You can choose to disable the collection of personalized advertising data for users who do not wish to view personalized ads or for your own compliance reasons. You can modify the global site tag and disable the collection of personalized advertising data for particular users on your site, or choose to exclude all users from California in the Audience Manager section of your Google Ads account.

Disable the first-party cookie setting

To ensure that Google Ads can measure all of your conversions, regardless of the browser that your site visitor is using, your global site tag sets new cookies on your domain that will store information about the ad click that brought people to your website.

If you don’t want your data tag to set first-party cookies on your site’s domain, add the following line to the tag configuration before you load the script tag:

var google_conversion_linker = false;

If you’re using conversion_async.js, add the highlighted portion below to the google_trackConversion call:

window.google_trackConversion( { google_conversion_linker : false } );

It's not recommended to do this because it will lead to less accurate conversion measurement.
