That still doesn’t give you any of the ranking boost – that is only given if you allow Google to cache it on their CDN. Google does that by default, you likely don’t even notice it, but if you try to prevent it, you lose the ranking boost.
For example, none of the newspapers reporting about stuff where I live support AMP, but a few US newspapers that report about sports events that happened years ago do.
So when I search about stuff in my city, at the top there’s an AMP carousel with news from years ago, and below that only the actual results.
No, you only get the boost if you allow any CDN to cache it.
Please stop making the same baseless claim without providing sources.
How can I do that AND get the same spot in Google search?
