For niche website hosting, how important is it to have each website have it's own IP?
Or is it no big deal to use shared IP?
I've read that if you are on an IP with a heavy spammer or something like that that it can negatively affect the other sites that share that IP.
Is that just a myth, or just very unlikely?
Look unique dedicated IP is not an attempt to make a fool anyone, but potentially it is an quality signal...Usually, search engines may use more than just IP to determine which sites are owned by the simialr person. However, having a dedicated IP address for each website is a good idea or at least you should have a one dedicated IP address for all your sites.
What hosts are good for getting different IP addresses?
