I have been very happy with how Google has treated my site over the last year, except for AMP. I have put a lot of effort into making my pages AMP friendly, but I still have very few AMP page views.
I wonder if other posters here will comment about whether they are happy or unhappy with their AMP page views (and revenue) compared to the amount of work they have put into getting them.
Also, did you have to achieve perfection with all AMP pages to get the traffic? In other words, never have a single error?
