Hey guys,
My company is in a middle of a redesign lanuch of their website. So we have m.domain.com and for desktop we just have domain.com and both rank well for their respective platforms in Google. In the current (old) structure we have a different site for mobile which is at m.domain.com. But on the new redesign we have a fully responsive site, so obviously best thing to do is redirect m.domain.com to domain.com.
My company is a bit reluctant to make the redirect switch from m.domain.com to domain.com on new design now as the next 1 month is very critical from business point of view so they want to play it safe and not do any mobile redirects incase there are any loss of rankings from the redirect as Google sometimes takes a bit of time to follow the URLs and what not. So they decided to make the redirect switch from mobile to desktop 1 month after.
So now that we are launching the new site on both m.domain.com and domain.com - both domains will have exactly the same responsive sites. How do you figure we should proceed to persevere rankings so Google doesn't see them as duplicate content? Would adding rel=alternate tag on desktop version pointing to mobile and adding rel canonical tag on mobile version to desktop do the trick in this case?
Many thanks in advance.
