There has been debate in the SEO industry for awhile regarding whether or not using a dedicated IP address is better than having a shared IP for your website…
- Some SEOs suppose that there really is no good reason to obtain static IP Web hosting. Your site will not perform any better by having its own static IP.
- Some others theorize that your choice of dedicated IP hosting vs. shared hosting might slightly affect your rankings (i.e. it’s a factor considered by search engines).
- Yet others suppose that sharing an IP address with known spam or adult sites raises a warning flag with search engines, so some of them may respond by banning the entire IP address from their index.
Most probably, these fears are greatly exaggerated. Since the majority of sites on the Web are hosted via shared IP, it would be unprofitable to search engines to penalize a site based on IP. Search engines are able to ban anything on a domain name instead of an entire IP neighborhood. So it is search engine safe to use a shared IP hosting. Moreover, almost all hosting will eventually be shared in order to preserve IP addresses.
