Is this the correct way to think about this? When building links for your site, either always use www preceding the domain name or don't put www before it, but never mix these. Stick with one method forever. And then set up 301 redirects for any url that could be considered the same page. Where, exactly, do you do the 301 redirect? If the above is correct, which one do you do? The www one or non-www? One poster said that he chooses to use non-www from here on out because that is the more modern way and another poster said that he uses non-www because he doesn't want his domain to be considered a "sub-domain."
NO, Never WWW is not necessary for the site point of view Google. This is depend on you that do you use www or not.
It very much depends on the URL... for long domain names it can sometimes be easier to type less of the www. Sometimes aesthetic reasons mean it might look better *with* the www. Whatever you do stick to one or the other.
I always have a full 301 redirect to "www" in my htaccess as well as have that set in the google webmaster tools when I register the site. Just be consistent with whatever way you go.
I'm using without "www" because of site name - it's a 3 words domain and sometimes I start each word with capital letter: MyDomainName.com.
I don't use www. and I don't thin that causes me any problem. The only thing is you have to be consistent for your links and URLs if you use it or not.
We mostly advice to use www and 301 redirection can help google determine that with and without www is the same site.
I use with www. Though it really doesn't matter what to choose between them, just stick to one and use 301 redirect.
yes i always prefer going with WWW as whenever we use 301 or in normal cases with optimization www is an effective way to promote your website.
always use www because with www and without www both domains will treat as different domain by google... so try to use www always
webdevelopmentcompany is very right - just keep it consistent. Another aspect is which way your visitors like it? Depends on a site niche, imho.
