Hello, I use GoDaddy's Premium Hosting. Right now, I have about 30 URL's and only have 6 sites on the account with little activity (just beginning SEO/Marketing). Does having all of the URL's on one account cause problems for anybody? I don't know if it would get in the way of the search engines or anything like that... But having a hosting account per URL would get extremely expensive. Thanks!
Normally it can't cause any problem. Although it is better for SEO that each domain is on a different IP
If you have a quality site with quality content, it shouldn't be a huge problem at all (I too use the same host to hold several of my websites and their rankings are fine)
I have mine setup the same way, and have never had any problems. One thing to consider, it to not link between sites since they all have the same IP.
Good point on the site linking. So, I should NOT link one site to another. Or would that just look like it is coming from the same website to the search engines?
