SEO optimization - Permanent Redirect

[jimmyz]

Search engines may think www.sitename.com and sitename.com are two different sites. You should set up a permanent redirect (technically called a "301 redirect") between these sites. Once you do that, you will get full search engine credit for your work on these sites.
Also, it shortens the URL. The 'www' is deprecated (the original purpose of the www subomain no longer exists) and shouldn't really be continued to be used.

Code: [Select]

RewriteEngine On
RewriteCond %{http_host} www\.sitename\.com [nc]
RewriteRule ^(.*)$ http://sitename.com/$1 [r=301,l]

So why you enter http://google.com it sends you to www.google.com ?
I think you should make it reverse , http:// -> http://www.

Just a few clicks arround the net (www.sitepoint.com/blogs/2005/06/14/examplecom-vs-wwwexamplecom-trouble/), and you'll see that these are two schools about this matter. I didn't really graduated none of them; I took the one mentioned above, it seems healthier to me, but I have to say, I didn't spend a lot of time investigating. If you argue with this, be my guest, enlight me, please. 
Anyway, you think redirection is a good thing?

Can you give me a famous site name that use this rule for itself?

google it's self has solved that ages ago.

if you have an acount at google-webmaster-tools you will be able to set how google will display your urls .... with or without www.
so it regognizes pretty well your site...doesn't it?

other engines? ....  who cares?

I think when search engines come to your site, they see www.yoursite.com as your main page of your site ...
Even you don't set in Google webmasters
see this :
http://www.google.com/#q=inurl%3A.com&hl=en&start=10&sa=N&fp=JJ2lHziMUzc

if you redirect your www.site.com to http://site.com , Then search engines go to that forwarded site to index the pages ...
So why we need to change www.oursite.com to http://oursite.com when search engines think your main page as www.oursite.com ?

Look go.com in the result of that page I mentioned ... in the result page it is shown as go.com , Not www.go.com , Because it forward itself to http://go.com ...

There is no different for search engines , As they index your all pages finally ... But why we need to forward our URL to http:// when they think www. as our main page ?

Didn't know that, ks-net.

other engines? ....  who cares?

So, you guys think redirecting is totaly pointless?

[ks-net]

that was a problem before a long time... thats true!

but now-days engines won't have any problem...

no need for a redirect!

[Farhad Sakhaei]

I agree with ks-net , No need for redirect , But I prefer to redirect the http:// to http://www.  Not the reverse

[Farhad Sakhaei]

Note for Elxis users :
When you are going to install the elxis , if you use http://yoursite.com in installation steps , Elxis will get your main url as http://yoursite.com not http://www.yoursite.com

So if any one come to your site , Your links (menu items) will be http://yoursite.com/blabla ...
I personaly don't like that , So when I want to install Elxis , I use www.mysite.com in my URL ... Also when I want to administrate the site (http://www.mysite.com/administrator)

[jimmyz]

I came through this, after visiting http://www.grader.com/.
grader.com itself, redirects.

My point wasn't which one should we prefer, but to redirect or not to redirect, as a SEO optimization?

I think it is better to redirect it ... But no different between http:// and http://www. for search engines ...
But I prefer http://www. because I think they go to our site and they think http://www.oursite.com as our main site

[Farhad Sakhaei]

Reason for my last post (I think it is better to redirect it):

http://www.google.com/#hl=en&q=site%3Awww.parsmizban.com&aq=f&oq=&aqi=&fp=JJ2lHziMUzc
site:www.parsmizban.com
Results 1 - 10 of about 271 from www.parsmizban.com. (0.18 seconds)

http://www.google.com/#hl=en&q=site%3Aparsmizban.com&aq=f&oq=&aqi=&fp=JJ2lHziMUzc
site:parsmizban.com
Results 1 - 10 of about 309 from parsmizban.com. (0.10 seconds)

They are different for search engines , So we should make both URLs as 1 URL (So it is better that we redirect http:// to http://www.)
Also we know www as our root of our site (known as : wwwroot )

What about when we have multiple parked domains at the main site ? What method is the best for seo ? Is need to use redirect ?
