different pagerank on forum index ?

our site have a forum,
and if you will type the url mysite.com/forum (which i really used when referring people to our site and links) - it shows PR2 on google's toolbar (i think google updated it since i didn't notice that before) but when you typed mysite.com/forum/index.php - it shows PR1 (like it used to be)

now i'm really confused as to what our forum's real pagerank is

 

I dont know much as i am also a newbie but as far as i know the page rank difference is due to different pages. It means Google has indexed your home page more than the sub pages. I am also developing blogs and they also have the same thing

You are leaking PR between the versions of your urls. Use a .htaccess file to 301 redirect to one version, also making sure you choose to use either use www or not.

This is known as canonical urls (canonicalization)

 

PR is given to pages not whole websites so your situation is very common, i had the same deal before - my blog had PR5 and then Pr4 inside and etc..

 

^but it's the same "index" , the only difference is that you access it using the folder name only (which is /forum), while the other one is /forum/index.php

both url's have a "www", the only difference is the ending - which is /forum and forum/index.php - but both url are the same page (index)

 

This sort of problem is quite common. It occurs if you have links (both internal and external) pointing to /forum/index.php instead of just /forum/.

 

For Google - mysite.com/forum and mysite.com/forum/index.php are to separate URLs. Hence different PRs. Naturally it is hampering the inbound PR juice to your forum . So you should try to either make a redirect or remove one of them.

 

becouse both of them google see as diffrent pages

 

how can i remove it?

can i delete the index.php on my /forum folder? i thought index.php is the reason why you have a folder index page? or should i just redirect it? (/forum/index.php to -> /forum only) ?

 

it depends on the backlinks.. I guess you have different backlinks for both /forums and /forums/index.php

 

You have some pr leakage. Use a 301 redirect so that you are only using one url.
