In order to add Google Conversion Tracking to an Instapage landing page, you will have to create a “Thank you” page, which will act as a conversion page. If you chose a template to create your page, check out the template gallery as most of them have a similar “Thank you” page already designed.
Afterward, you will have to link the conversion page to the form on your landing page. Here is the quick guide to help you.
After you have created and linked the conversion page to the landing page, all you have to do is place the Google Ads code on it. Here’s how:
1. Open HTML/CSS from the settings menu;
2. In the Body section, paste your Global site tag together with the conversion tracking tag. If you haven't created your tag, follow these instructions to create it;
3. Save the changes to your landing page and that's it.
