Wondering what the consensus is for pointing url anchor text pointing is. If google is displaying NO WWW in front of the domain name on a search of that domain, are you pointing the links right at http://domain.com OR do you still get the same authority no matter what you do?
If you have a 301 which redirects the non www to www then you get the same link juice. If you don't have one set up then make sure you point the links to the proper extension that you want the links pointing to.
Google doesn't care. Decide which one you like the look of best, then send all inbound links to that version and 301 redirect the other version to the one you've chosen.
In technical terms as defined by Mattcutts of Google, this is called as canonicalization. He said that Google bots considers all these(http:// or www) as different domains! Using .htaccess file with 301 Redirect will help you solve this issue! For more information, search canonicalization in Google and read what Mattcutts explained in his blog!
I agree to the point its; known as canonicalization which means that you have the same data under two different domains yes they both are considers as different URL
Well, Best thing is use htaccess file and upload in your site you can also create google webmaster tool and it will show you how your site is working and it will providing same kind of facility.... for the example if you are open google without www. then it will redirect and open with www. Not even google infect almost every big site or search engine also using same technique....
