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 support@innroad.com and ask them to enable the dataLayer. We can then embed the script into the booking engine.
