I have a website that is currently hosted with GoDaddy's $6.99 deluxe plan that allows unlimited domains/websites. The site has a PR of 4. I just bought a domain that has a PR of 3. I was wondering if it would effect PR it I put them on the same hosting plan or does that even matter at all? Would it be better to get a seperate hosting plan for the new domain? Obviously, I want to keep the PR for both. Thank you.
PR has nothing to do with your hosting plans or your hosting provider. You can host several domains under one account or you can use dedicated server for each domain its not going to affect the PR.
