We have the following case:
Site A with domain authority 65 and 2,750 linking root domains (139K total links) and
Site B with domain authority 68 and 1,336 linking root domains (38K total links)
There's a suggestion to move Site A as a folder of Site B so it becomes something like this: domainB.com/domainA using 301 redirects for the existing domain A. We'd like to better understand what such move will result in.
I imagine at first Site A will drop in rankings, but after that will it be better for it to be under Site B domain? Also, moving all the pages a step behind in the URL path may slightly affect their rankings.
What do you think? Would you move Site A or leave it as a separate domain? I understand there can't be an exact estimation what will happen, but I'll appreciate your thoughts.
