I have a couple of websites around 8-10. What is the best way to link all of them to get the maximum link juice?
You own Site A and B You contact site C and ask them to link to site A and in return link to site C from site B. Then Google comes along and thinks its a one way link.
Technically, you can. Link weight is less though because its from the same C Block IP address, but it will still boost your PR.
I wonder how that works really because a main pages inner pages pr will become less by one as you dig deeper. You would think the ip wouldnt matter unless Google aknowledges is as a seperate domain.
Interlinking a bunch of sites might not be a good idea anyway. You might not get done for link farming but it definitely wont look natural.
