Do you lose any points or weight or whatever for this? If I have 5 site's and all are linking to each other (off topic)..Could this hurt me? 1 has pr4 and 1 has pr5..the other 3 are pr0..should i stop doing this?
It's possible. Are the sites relavent to each other though? Are they on different C class IP addresses? These are some of the things you should be asking yourself before you start inner linking sites.
Thanks for the response. The site's are sharing the same C class IP and are not very related to each other. Because I answered yes to both of those questions im assuming this may not be the best idea inner linking them?
