Ensure Conversion Coverage
Account for as many observable ad-click-to-conversion journeys as possible.
Start with a strong tagging infrastructure
Tags are the foundation of privacy-centric measurement. Sitewide tagging, using the Google tag or Google Tag Manager, allows you to make the most of the data that customers share with you by placing first-party cookies on your website to measure conversions.
Benefits of sitewide tagging
Maintain measurement accuracy
Ensure more accurate conversion tracking by specifying which interactions should be counted as Google Ads conversions.
Streamline integration
Sitewide tagging provides faster, easier integration across other Google products, like Google Analytics 4.

Frequently asked questions
Google Ads only collects data on pages where you have deployed the associated tags. It’s important to provide users with clear, comprehensive information about the data that you collect on your website, and to get consent where legally required or required by Google’s policies.
To help you keep pace with industry changes and continue measuring performance, Google has further improved the tagging experience. The Google tag is a single, reusable tag that replaces the global site tag and simplifies measurement with new capabilities that don’t require additional code. If you have the global site tag set up already, you will not need to make any changes. Your existing tag implementations will continue to work and will be automatically updated to the Google tag.
If you need to manage multiple tags on your website, we recommend using our comprehensive enterprise tag management system, Google Tag Manager. It allows you to configure and deploy tags from a variety of Google and non-Google products within the same interface. If you’re looking for a simpler implementation directly on your site, we recommend setting up sitewide tagging via the Google tag to power measurement across Google Ads and Google Analytics.
