Only one of the sites is ranking, but how strong is the ranking based on the extremely on topic supporting sites?
I usually try to have multiple sites at arms length to give me multiple positions in the serps, but wonder if I may be going about this wrong.
We're considering converting an old underperforming mini network to this approach, but it is hard to know exactly how far to push it. One conclusion we have drawn is that if you're going to do it, you better also have a bunch of external inbound links from sites not related to yours - those inbounds seem to provide a good level of insulation. Watch those dup filters too, if your site templates are similar. FWIW.
If your sites have different enough content, are hosted on unique C classes and have a good amount of links from other quality sources, I think the risk of linking your sites together is rather low and will give you some boost, especially in Yahoo.
at another forum, I saw someone that was really really adamant about the use of different class c's. I checked out some of his sites- sure enough, they were on different class c's. however, the domain whoises (and not to mention the location of the server) were identical. ;)
