I have a site which is doing very well in all indices except ink. It is certain that it has been given a penalty because it lists at bottom of SERPS even when there are only 20 results being returned. I suspect that they gave it because of "excessive crosslinking" .. because we made a sitemap type page and put it on another domain instead .. and had 300 links from that page to the main site (sinned yes .. but that was long back :D) .. and that might have kicked off a spam filter.
We have closed that other domain for a few weeks now and sent an email to email@example.com for review.
Is there any thing else that I can do.
Any advice is appreciated.
