i do have 20 domains on the same host i want to interlink all of them with each other .. what would be the drawback if i do this from the same ip
In my opinion, as long you find the way to interlink each site properly and randomly everything could be ok. I have many sites and the strongest one push the weaker ones. Nevertheless, I do not link back from the weak to the strong one.
If all the websites are related to each other, have plenty of unique content...probably no harm, but also limited benefit. The thing is it should not look like a manipulated 'link scheme'.
you are trying to say that linking must be like this ? 1 to 3 2 to 4 5 to 7 and 6 to 8 ? is this you are trying to tell me ?
what could be the draw back if i wil link niche to niche with unique content on both websites ... i am linking from pr 0 to pr 2 and pr 0 is just 6 months old
