How Google choose www. or no www. from our site?

I just checked some sites backlinks

why http://paramegsoft.com/ has no backlinks reported
but http://www.paramegsoft.com/ has many many backlinks?

another site http://dmoz.com/ has many many backlinks
but why http://www.dmoz.com/ has no backlinks listed?

How G choose www. or no www. from our site?



Thanks

 

Go to webmaster tools in your google account and you register and confirm your site, then there will be an option to select which one that you prefer

 

That would depends on the site on what URL they're using when getting backlinks. If you use URL with www on your anchor text then google will indexed your backlinks with www

 

What if some sites who do not use G webmaster tools?
How G going to select ?
Any for G default setting?

 

Its depends on how you optimize it!

If you use www. then Bk count on www.

 

Or just do a 301 redirect on your htaccess to the one you want to use

 

would that be possible
you use 301 redirect all www. to no www. but G choose all www. from your site
What will happen if like that ?

Thanks

 

Yes - you can redirect like that

redirect to www , then set www in webmaster tools

I have it redirected to my www URL. This is what i have in my .htaccess file:

 

Google takes its cue from you. So if you redirect www to no www, google will just decide to index the none-www version. Same with using webmaster tools.
