Google Analytics and Salesforce have released a native integration, but it has two major downsides:

  1. It only supports Google Analytics 360 (which costs $150k/year).
  2. It only supports a small set of data points from Salesforce (Lead Statuses, Opportunity Stages etc). If you need to send something beyond that to GA, GA Connector can help – because it supports sending any type of Salesforce objects and fields to Google Analytics.
