I have a desktop site with loads of old Flash games on it. Since there wasn't any way of easily porting that to mobile, I have a completely different mobile site with a different set of HTML5 content options.
I've been through Google's documentation on mobile redirects (here: https://developers.google.com/webmasters/mobile-sites/mobile-seo/configurations/separate-urls) and it warns webmasters to maintain a 1:1 relative structure between the desktop site and the mobile site.
The thing is, that's not something we can do. The mobile site by definition must have very different content than the desktop site which has content that won't run on mobile.
So what are the best practices for mobile redirection? I'd like to just redirect all mobile traffic to the mobile homepage (as I can't really see any other option).
But Google cautions against exactly that:
That above diagram of "what not to do" would seem to be "what I'm about to do", and I feel a bit strange preparing to implement exactly the thing they warn against doing. But I can't see any other options. Are there any special steps I should take to prevent that choice seeming like an error in terms of SEO?
