Diffrent Page Rank for SAME page

[mann]

Hello There,

When I see at my site page using http://www.example.com it shows PR1.

And when I use http://example.com it shows PR2

How to over come it?
Does it means the same Page have PR3 but divided in 1+2?

Please ans my query,

Thank You

It means you have more incoming links as site.com instead of www.site.com. The fix is to decide which way (with or without the "www" you want your site linked to. Then contact those site linking incorrectly (assuming there aren't hundreds since you have a PR of 1) and ask them to update the link.

domain.com and www.domain.com aren't the same page - the www version is a sub-domain of domain.com. As Frequent says, the PR difference is due to inbound link difference to each version.

Thank you for Quick Reply,

But is this mean if I make it either www or non www than the same page after next G update will fatch PR3.

As now it is PR 1 & 2 (with & without www)

The terms "URL" and "page" don't mean the same thing. In your case there are two different URL's for the same page. This is because 1) your provider has configured DNS in such a way that the subdomain www.domain.com points to the same host as domain.com and 2) your webserver is configured to treat every URL with "wwww.domain.com" as an alias of the corresponding URL without the "www." Depending on the particular webserver (Apache, IIS, etc), this aliasing can be achieved in many different ways.

PR is associated with URL's not pages. Since you have two different URL's, each one gets a PR of its own.

URL aliasing causes problems because the search engines see two or more different URLs that return the same content. In particular, aliasing

- can lead to a duplicate content penalty,
- distributes your PageRank accross more pages leading to a weaker SEPR position of each of the URLs and
- confuses your visitors.

What should you do? As GoogleGuy recently recommended, try to be consistent with your links. Pick one hostname, either www.domain.com or domain.com and stick to that for the rest of the site's life. Ask everyone that links to the "wrong" hostname to change it to the "right" one. Change all internal links to point to the right hostname. Lastly, disable the URL aliasing and setup a 301 (permanent) redirect from each wrong URL to the corresponding right one. The last step makes sure that the search engines realize that the wrong URLs should not be used anymore. It also redirects users that type wrong URLs into the address bar of their browser or that have bookmarked wrong URLs.

After you setup the redirect or adjust all links to use the right hostname, the PR will be combined, but not by adding it up because the toolbar PR is on a logarithmic scale. A PR2 is approximately 6 times more than a PR1. Or you could say a PR1 is one sixth of a PR2. If you combine a PR1 with a PR2, you get a PR2 + 1/6th of a PR2 which is still a PR2 unless the PR2 is very close to a PR3 in which case the combined PR might be 3. How can that be? Internally, Google doesn't use the toolbar PR (TPR) for ranking. Instead it uses a more accurate and linear number, the internal PR (IPR).

An IPR of 1 to 6 becomes a TPR of 1, 7 to 60 => 2,
61 to 600 => 3, 601 to 6000 => 4 and so on. Let's assume the wrong URL of your homepage has a IPR of 6 and the right one has a IPR of 30. 30 + 6 makes 36 which is still an TPR of 2. If the right URL had a IPR of 57, the combined IPR would be 63 and a TPR3.

The logarithmic toolbar scale of 6 that occurs in my calculations is purely hypothetical. It might be a 10 or a 20 but the principle stays the same.

Thank You Hanu,

Your detail description is very intresting for me as I come to know various new things.

Sorry, but can you please tell me (as I am not a software or technical person) which one is easy to over come this problem, which one should I use "301,redirect or adjust all links to use the right hostname"

Sorry but due to very less knowledge I have to ask all these dumb questions.

Have a nice time

As Frequent said above, your relatively low PR suggests that you have only a few incoming links. So asking for the links to be changed is probably easier for you. I personally would both change the links as well as set up the redirect.

But even if you don't do the 301 redirect, you need to disable the aliasing! Even if there aren't any links using the wrong hostname, as long as GoogleBot can still retrieve pages for the wrong hostname, you risk a duplicate content penalty.

Thank You all of you, nice to be with you all.

I try some of your suggestions.

Lets hope positive for future.

Have a nice time.
