Accelerated Mobile Pages (AMP) technology that help build faster-loading pages for all types of sites, is though supported by Google Analytics, however, webmaster face difficulties during users analysis due to site visitors being identified inconsistently across AMP and non-AMP pages.
To solve this issue, today, Google rolls out enhancement to provide even more accurate understanding across AMP and non-AMP pages on website.
The change will bring consistency to users across AMP and non-AMP pages served from publishing site domain and unifies users across the two page formats to improve user analysis. The change don't affect any AMP page served from either Google AMP Cache, or any other AMP cache.
The chnage will complete over the next few weeks across all Google Analytics accounts.
Google says, you can expect to see a down fall in user and session counts over time, because the the two formerly distinct IDs are in fact recognized as the same user. Once the change commences, the New Users metric may rise temporarily as IDs are reset.
In addition, with AMP and non-AMP pageviews will no longer being treated as multiple sessions, the metrics like time on site, page views per session, and bounce rate will rise consistent with sessions. "This is a one-time effect that will continue until all your users who have viewed AMP pages in the past are unified," google says.
Google also notes, there is no action required on customers part, as the changes will be automatically rolled out.
Further, Google explains, that currently their focus is on fixing publisher domain, so there will be no effect of unify users who view my pages outside publishing domain via AMP caches or in platform experiences.
