I have three sites in related niches. Site A is 2 years old with PR5, Site B is one year old with a PR4, Site C is one month old with no PR. Right now I have links from Site A to Site B and Site C. I also have links from Site B to Site C. (So, A->B, A->C, B->C). I am wondering whether or not to link all my sites together. That is, should I put links from B->A, C->A and C->B? I am worried that if I do that Google will view these as link exchanges and devalue all the links. What if I made the new links using a no-follow attribute? Any suggestions?
Yep. Might happen. I wouldn't do it. I'd keep the links exactly as they are now if I were you. Anyway, if you care about the SEO aspect of links, (PR transfer and link popularity), then don't use rel=nofollow. If all you wish to get is traffic from your other sites... heck, I'd still not use it, since you should only really use this tag when I can't vouch for the link, but then again: Why post a link you can't vouch for? Also, if you interlink all your sites I'm not sure Google won't see it's a link exchange anyway, even if you use rel=nofollows. There was a thread with this question raised, but I guess we don't have a reliable source to confirm it: http://forums.digitalpoint.com/showthread.php?t=111607&goto=nextnewest Hope this helps, Warkot
I have around 40 sites and most of them are cross-linked. My sites have not been penalized in a way that many fear. Cross-linking your site can help pass visitors from one of your site to another, keeping them within your network of sites rather than leave it for another site.
Reading that other thread gave me an idea. I can go ahead and use JavaScript to make these new links. (But still keep the original links as plain text links.) This way Google won't even be able to see the links, but I can still get visitors. If I'm extra paranoid, I could also do as Matt Cutts said on his blog entry: "you could also make the link redirect through a page that is forbidden by robots.txt" Excellent!
