Is Backlinking this way any good?

[ruxi]

I never thought about this before - but I have a client's landing page that has listed in the SERPs as: abc dot com - however, I backlink to his landing page as www dot abc dot com.

Should I backlink to his site the way it is listed in the SERPs (in other words - drop the www) or does it really matter?

I think its important to tell Google the preferred url (with or without www). You could use a 301 redirect for the domain without the www. Does your client or you have a lot of backlinks where the domain is without the www?

I think Google is concerned that www. site . com is a different site: to site.com - and it takes Google a very long time to merge the data. As it is difficult for them to generate and have a clear concept of your site.
Redirects are great idea.

I would use a redirect and be consistent about how you list the site. Pick one and go with it.

Yes, I would do 301 redirect to www and build more backlinks to it, should see the changes pretty soon!

If you have more (or all) www backlinks Google will eventually, it least in most cases, use that has your Canonical URL and show the www URL in the search results.

To make sure you get the “link juice” from any non-www links and avoid any duplicate content issue (the search engines may actually view the non-www and www as duplicate pages) you can use a 301 redirect.

Matt Cutts has put out a lot information on the URL Canonicalization and the duplicate content issue.

You can now (started back about February) specify your preferred version of a URL in the page header.
