Hey Max,
We’re heavy Google and Microsoft Ads as well. I use Google Tag Manager (GTM) for all tracking/pixels. That way, you can have one container (GTM code on your website) with all tracking codes. We use Analytics, HS, Google Ads, Microsoft Ads, Facebook, and LinkedIn all in one container, so we have access to all platform data.
When you add the Google Ads pixel to HS, it will track ads conversions to customers. You can also set up HS events. Using GTM to set up Google Ads conversions is odd at first, but once done it’s worth it from a maintenance standpoint.
What I really like about the HS-Google Ads integration is setting up audiences in HS for use with display and remarketing ads in Google. Targeting specific HS visitors works very well.
Good luck!
