link:www.domain.com different than link:domain.com

If I type the following into Google:
link:www.saynotocrack.com
I get a different # of links (1,620) than if I type in:
link:saynotocrack.com (0 links)

Why is this? I've noticed other sites, like Neatorama, don't show this difference. Is something setup wrong on the site? Can this impact SERPs?

Thanks!

I was able to access your site directly with either the www or non-www version.

As it stands, search engines may treat the two versions as different domains, confusing them a little. Also, it can mean your link equity is spread out between the two versions, possibly hurting rankings.

The standard answer is to 301 redirect the non-www version to the www version of your website. Most good hosting providers should be able to do this for you (some even have it as a control panel option). If not a techie person on here should be able to help you with some further advice (or search google for a solution).

Also, in Google webmaster tools (sitemaps etc) you can tell them which version you want them to look at, www or non-www.

It means you have always used www while building your links. As G treats these two --as separate urls --you mat be well -off doing a re-direct.

 

You may also use google sitemap and tell google about your preferred URL.

 

The non www version will also show links to the sub domains of your site

 

which one is best, www or non www? Knowing that non www show links from sub domains?

 

If you use Apache do a 301 re-direct and put this in your .htacces file

RewriteEngine on
RewriteCond %{HTTP_HOST} .
RewriteCond %{HTTP_HOST} !^www\.saynotocrack\.com
RewriteRule (.*) http://www.saynotocrack.com/$1 [R=301,L]

that will re-direct all request for hxxp://saynotocrack.com and forward it to hxxp://www.saynotocrack.com. It will also help prevent problems with search engines thinking your 2 urls are different sites.

 

Awesome suggestions, thanks all!

 

No, URL with www is URL with backlinks without www. In short, when you do the link: on the URL without www, it would show all the linked URLs having all URLs with or without www, but if you use link: on the URL with www, it would only display links having www on the URL.

 

I just received a warning for this being in the wrong category ... not complaining at all, but I am curious - why would this be classified as Reviews...SEO? I was just trying to figure out why Google results were different for each scenario and the impact.

Thanks!
