This article might save your Google Analytics developer a ton of time.

If you have an email or customer list that engage with your site it can be frustrating to try to figure out how to connect those data with the Google Analytics User Id.

Many tools like HubSpot, Marketo, Leadberry, and Salesforce have ways of tracking individual website browsing behavior. Hubspot has it’s own unique javascript that tracks users, Salesforce lets you connect with Google Analytics with custom dimensions, LeadBerry connects their network data with Google Analytics data to help identify customers.

There are also ways of hacking together systems that let you use the Google Analytics User Id by pushing your site’s user ID into GA. However, be warned that Google Analytics policy prohibits you from adding PII (Personally Identifiable Information) into Google Analytics. So you need no make sure the id pushed in doesn’t have this info – like email address.

The Problem

  • Google Analytics User Id’s track past 2 years of website browsing behavior on your site but they are anonymized.
  • Tools like HubSpot cost hundreds of dollars a month for this website customer tracking set up in a usable way.
  • Pushing your User ID into Google Analytics doesn’t provide a quick way to browse and access this information.
