Forum Moderators: phranque
I know that this topic has been touched on before but I couldn't find the thread, so apologies if I'm going over old ground. I have 5 sites that are now all on the same IP address - I'm looking to change this and give each one an individual IP address - will this be more beneficial for my search engine ranking and linking? I understand that it will overall but just wanted to confirm.
many thanks

I think the general principle is, it might do. And although no-one other than the SE operators themselves could give you the definitive answer, given the low cost of multiple IP's these days, it's got to be a good recommendation to have one IP per domain.
But I wouldn't go too mad on interlinking unless you have IP ranges with different c-classes (at least) and even then, be very careful.

Because of that, it's a good idea to run both IP's side by side for a while.
If you have access to the TTL (Time to Live) settings on your server for the domain having it's IP changed, set it to a low value a few days before you switch. Most of them go down to 75 seconds. A few of them are set high - lowering this will speed up the process slightly.
Just leave an exact copy of the entire site on the old IP address until you see that all the bots have updated their DNS cache (your logs will tell you as all the bots will be hitting the new IP).
My own personal experience of doing this myself with two sites only a few months ago was that none of our rankings in any of the search engines suffered at all.
