Different IP for domain and www subdomain. What will the search engines think?

Question

Search Engine Optimization

There are different IP addresses for the site domen.ru and www.domen.ru. Does it affect SEO? In particular, is it possible that search engines will identify them as two different sites?

Answer 1

Your case is very similar to Round robin DNS ( http://ru.wikipedia.org/wiki/Round_robin_DNS ), so I don't think search engines will look at the site any differently.

Answer 2

This option is possible, and it can become a problem when promoting. Set up a redirect (301) from a domain without "www" to a domain with "www" or vice versa.

Answer 3

If the sites are different, then maybe.
If they're the same, then it's unlikely.
