They can, but don't get credit for it in Google's page rank. Which to me makes the whole complaint sound dishonest. They want to have their cake and eat it too.

>don't get credit for it in Google's page rank

How do you know that? There are very few people in the world who can claim that with evidence.

I haven't tested it but google shows a lighting bolt next to amp sites so maybe the custom amp websites dont get the bolt.

That should be easy to test, given that cloudflare hosts a top-level AMP cache. Just check if a cloudflare-cached website gets the bolt.

They do get the bolt.

This isn't true. Example:

- Miami herald rolls their own amp pages: http://amp.miamiherald.com/news/business/article135187364.ht...

- Here's the icon in search for the same page: https://i.imgur.com/43Hk7tV.png

From what I understand, google bots detect the amp standard and flag it with the amp tag for mobile search results.

They host their own pages using AMP, but they still are forced to use the one centralized JS file implementing AMP.

The point was that even if websites host their own AMP standard, they still get the AMP icon in mobile search results.

I'm not sure what point you're trying to make about using js files.

What do you mean by "their own AMP standard" then? I thought that meant a customized version of the AMP elements/framework.
