Common Issues

Since Google Analytics captures data on the client side, it's susceptible to the following behavior.
  1. Use of a script or ad blocker.
  2. The buyer navigates away from the order confirmation before Google Analytics can record data.
  3. Your website is not SSL secure. This causes referring data to disappear. 
From our experience, around 10 - 20% of transactions will go missing. However, as long as the error is consistent, you should be able to draw conclusions so perfect data isn't necessary.
