With AMP page tracking has come many problems for us. First is the idea of how to track this channel. We came to the conclusion we would include it in the last touch channels, by page, for anything that contains "amp".
Our pressing Issue
We are finding that are some tracking issues specifically with safari. When comparing visits to sessions in GA (since we have our site tagged in GA as well) we are finding that AA shows visits & page views 5X greater than sessions specifically for Safari. We are wondering if GA is under counting visits, or if AA is over counting has anyone else experienced this issue?
