I have a colocated server with 64 IP's assigned to it and 70% of my sites are all in the same industry. I only put one domain name on each IP just to be safe, but I'm wondering if I will be penalized by Google for having all these sites on IP's that are so close together. The content between all the websites themselves is about 50% different.
The only 2 factors that are the same are (1) same industry & (2) close IP's.
Anybody have any experience with this or know if it's a problem?
