We’re turning off AMP pages at Search Engine Land
Publishers have been reluctant to remove AMP because of the unknown effect it may have on traffic. But what our data seemed to tell us was there was just as much risk on the other side. We could keep AMP pages, which we know have good experience by Google standards, and their visibility would fall anyway due to competition in Top Stories and waning support by social media platforms.
