With all of the pros that come along with Google AMP, it also has its fair share of cons. With that said, many of these issues will most likely clear up as the program develops further and Google works with its users. The simple answer is that Google AMP is not for everyone, preventing sites that are not blogging or publishing articles to reap the benefits.
Another common complaint is that Google AMP does not directly impact Google ranking. As many predictions say, Google will most likely add Google AMP to the ranking algorithm in the near future. If you’ve noticed, when a user navigates to a Google AMP page, the URL provided is just added on to the already existing google URL, directly impacting website domain authority. The user is not viewing this through the publisher’s URL.
