Is It Better To Have Different Hosting Accounts For Different Sites?

I've got a resellers account with about 30 sites on it, but I can't seem to rank more than 1 or 2 of those sites at any one time.

Is it better to have multiple hosting accounts for multiple sites? Does anyone have anyb experience with this?

Check with the host how many IP addresses you can use with your account - then spread the sites across different IPs

Yeah I did get on to them and asked that very question...still waiting for a reply...
