Google Ads Conversion Tracking setup - Google Tag Manager

Tracking your booking engine reservation revenue via Google Ads is a great way to understand your sources of income, as well as the performance of each ad you run.

To start the process, please send your Google Tag Manager script to [email protected] and ask them to enable the dataLayer. We can then embed the script into the booking engine.
