In my case if i use a mobile devide i want everything to be in amp version.
That's a slightly different thing. These options are for automatically redirecting mobile visitors
to your AMP pages. We have not implemented that yet because it's an extremely rare use case. It can only be used when you have a 100% feature and content parity between your responsive pages and your AMP pages.
As Google now uses mobile version for indexing your site content:
- you are adding a redirect before each mobile page, big speed loss and negative ranking factor
- most importantly, you need to be sure that absolutely all your site content, images, structured data, sharing tools and features (newsletter signup, registration, add to cart, payment, etc) is available also on the AMP version. If not either Google or your visitors will miss part of your website.
It also has the drawback of tying your to this method. For instance you may not have now a newsletter signup or another form, but tomorrow you may add that to some pages. But if that feature cannot be implemented easily on AMP, you're stuck or you need to change the URL of the page back to non-AMP and customize the redirection tool to redirect back the old AMP version to the new HTML version. All is doable, just asking for trouble and work.
Like I said, 100% parity is doable, it's just extremely, extremely rare in your nearly 4 years of experience with AMP!
Lastly, note that if you are in that state of mind and have been able to convert all your website features and content to AMP, then I will suggest instead to create a "Standalone" AMP site where ALL the site is AMP with no HTML version at all (see the Operation mode on the main settings page).
Both Mobile and desktop users will get the AMP version, there will not be any /xxx/amp URLs anymore and that's probably pretty good for Google. This would be our recommended choice if you achieve feature parity.
Now the question was more about the links on a page and as I said, I agree the logo should go to the AMP version, if the home page has an AMP version.
