Working with a new client.
They have what I would describe as two virtual websites. Same domain but different coding, navigation and structure.
Old virtual website pages fail mobile friendly, they were not designed to be responsive ( there really is no way to fix them) but they are ranking and getting traffic.
New virtual website pages pass mobile friendly but are not SEO optimized yet and are not ranking and not getting organic traffic.
My understanding is NOT mobile friendly is a "site" designation and although the offending pages are listed it is not a "page" designation. Is this correct?
If my understanding is true what would be the best way to hold onto the rankings and traffic generated by old virtual website pages and resolve the "NOT mobile friendly" problem until the new virtual website pages have surpassed the old pages in ranking and traffic?
A proposal was made to redirect any mobile traffic on the old virtual website pages to mobile friendly pages. What will happen to SEO if this is done?
The pages would pass mobile friendly because they would go to mobile friendly pages, I assume, but what about link equity? Would they see a drop in traffic ?
Any thoughts?
Thanks, Toni
