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?
or on a sub-domain?
or somewhere else? Or does this not matter in the modern world of white hat SEO and content?
