Add a conversion tracking tag to your website
When you create a conversion action in your Google Ads account, you’ll get a conversion tracking tag to add to your website. This tag tracks when someone who’s clicked your ad goes to your website and completes an action that you’ve defined as valuable, such as a purchase or sign-up.
This article explains how to add the tag to your website. Before you begin, make sure you’ve first followed the instructions to set up conversion tracking for your website.
These instructions are just for conversions that happen on your website. For other kinds of conversion tracking, like apps, phone calls, or offline conversions, find the instructions here.
