Would love some advice from those who know please.
Here is my situation. I had a penalized site. (Call it Site A). Site A has been penalized for a long time, with a "unnatural links" warning in Webmasters. I tried to recover it, (with some link removal and disavow file), but Google isn't doing anything. So Site A for me is dead.
Instead I created a new site, Site B, just very recently. In order to avoid a duplicate content penalty from Google, I did a temporary redirect (302), from Site A to Site B. I chose 302, to tell Google this is temporary, i.e. not to pass any link juice.
HOWEVER, today I have found out that all my Site B rankings have disappeared! But Google have not given me any warning in Webmasters.
Basically, I need advice on what to do, and how to recover Site B.
I've already removed the 302 redirect.
Many thanks.
