Multiple domains for the same site.

Best practices to buy and point the spelling mistakes domains

[craig1972]

Hi. I have a domain abc.com. This has its own NS servers under a cpanel and whm setting, so I have ns1.abc.com and ns2.abc.com.

Now, we have also discovered that other domains similar to these are common misspellings of our domain name. So we have bought several domains but they are actually the same site.

There are now two ways to point (or park?) these additional domains to my main abc.com:

1. Give all of these domains the same NS values of ns1.abc.com etc. (This is how we have it now and it works).

2. Or, let them have the default NS servers from the registrar (GoDaddy) and just set their A record to my abc.com's IP address.

My question:
Does it matter from a search engine desirability perspective which option we take to point multiple domains to our website?

Point them all at one server, then use a redirect so that all non-canonical URLs are redirected to the one domain you really do want to be used for the site. Ensure the redirect is a 301 redirect, and that it preserves the requested path-part from the original request.
