Hi, @TMerkel 
Thanks for reaching out! Let’s invite some of our community to the discussion — hey @Anton @Teun @alyssamwilie, do you have any experience you can share?
My guts says there are a few options to consider:
- HubSpot Specific — Create Custom Behavioral Events (Marketing Hub Enterprise) Required) to track views and retention
- Google Analytics
And I’d love to know what other options I am missing.
Thanks for taking a look! — Jaycee
