Search engines listing
 

Do you think it's better to have sites here and there on different hosts/part of the world with different Ips for search engine placements ?

I wonder if they will list sites coming from the same place (server,ip etc...)
Like if you have gay, lez, bdsm or whatever domains.You will probably not wind on the top page for all your stuff

Surely not, to kinda like "give a chance to everyone"

Your views

that's why you should use unique ip's for your domains.
