I’ve only personally benefited from AMP in times when I was trying to read the news in very congested LTE situations (e.g. an indoor arena filled with spectators) so keeping the absolute number of requests down and aggressive preloading was helpful.

I am seeing far fewer AMP sites today than before though - Google promised higher search results rankings in exchange for a modest amount of work to make websites AMP-compliant - but I guess media publishers see the end-result being more work for less reward, especially if they can’t use their user-tracking scripts.

What’s the advantage of doubling pageviews from higher ranking when it means you get less than half the advertising revenue?
