'C' Class IP Effect For SEO?

[Robert J]

If you have more than one domain directed to the same web site (or sites that appear to be the same), Google may de-rate them as being parked or some kind of auto-generated site.

If the sites all have significantly different content, the same IP & owner info does not matter.

If they are the same, you are far better off having just one with content and set up 301 redirects on the extra domains to transfer visitors to the main site.


Google understands redirects and will see all hits or links on any redirect domain as being for the main one.
You won't see the others in search results, but the main one will have far better ranking.
