apologies if this is known science around the web mastering community, I haven't had to worry about content in a number of years and don't know where to start :)I'm considering implementing Google's Accelerated Mobile Pages for my website.  It's my understanding that I can create two different versions of a page -- one for computer browsers, and one for mobile browsers, and then I can use a <link/> tag from the HTML page to point to the amp version<link rel=amphtml href=__MY_AMP_URL__>and in the AMP version of the page, include a canonical link to avoid duplicate content penalties.<link rel=canonical href=__MY_REGULAR_HTML_PAGE__>Are there any best practices, or known science, on where to put the AMP version of the page?  Should they be on the same domain, but at a different path?http://example.com/foo.htmlhttp://example.com/amp/foo.htmlor on a sub-domain?http://example.com/foo.htmlhttp://amp.example.com/foo.htmlor somewhere else?  Or does this not matter in the modern world of white hat SEO and content?
