Ok, I just checked out my sites in
google.com and found out a huge amount are eiter sandboxed, banned, missing or indexed. Here are the results..
Out of 24 domain.
13 Sandboxed (many of these used to be indexed, some with 100's of pages).
5 Not indexed at all (including 1 banned URL)
6 Indexed but doing fuck all in the serps..
Many of these domains have been around for awhile and contain quite a large amount of original content..
What I would like to know is the best way to link these sites together without incurring penalties...
