It's official: AMP results are now live in Google Search even though Google haven't previously announced a certain date for when this will happen.
AMP (accelerated mobile pages) will appear strictly for mobile searches and requires prior implementation and setup from website admins. Sure some functionalities will be lost in the AMP transition but Google shows it clearly that if you don't implement AMP, you will your ranks on mobile searches, therefore, your mobile traffic can greatly suffer since Google prefers showing AMP results pages rather than plain old HTML pages.
Anyways, I've made a couple of test on my android 6.0 LG smartphone and discovered that my Google Searches lack AMP results, read some rumors that AMP will actually be available from Android 7 onwards.
Guess will have to wait and see what happens, I still hope this won't become a thing and Google will let us have our own pages with our own functionalities without implementing a standard for mobile pages.
