Web Hosting Talk : Web Hosting Main Forums : SEO / SEM Discussions : Mod_Rewrite Help Needed

[ufhosting_Leon]

I use WHMCS for my hosting client control panel.

I today decided to use mod_rewrite to try and improve SEO on the URLS for my knowledgebase. Below is the .htacess file I used:

RewriteEngine On
RewriteRule ^knowledgebase/([0-9]+)/([0-9]+)/[a-z0-9_-]+\.php$ /whmcs/knowledgebase.php?action=displayarticle&catid=$1&id=$2 [L,NC]
RewriteRule ^knowledgebase/([0-9]+)/([^/]*)$ /whmcs/knowledgebase.php?action=displaycat&catid=$1 [L,NC]

The thing is, people can still use the old URLs...

For Example:
http://www.ufhosting.org/whmcs/knowl...vious_host.php
is the same as:
http://www.ufhosting.org/whmcs/knowl...laycat&catid=1

Now I have heared having two pages with the same content can negatively impact your search rankings.

The problem goes further, if you go to:
http://www.ufhosting.org/whmcs/knowl...vious_host.php
and click on the bread crumb navigation it takes you to:

http://www.ufhosting.org/whmcs/knowl...laycat&catid=1

which again is the same content with a different address... three pages then all the same content. Google wont like that? I cannot edit the bread crumb navigation due to the source being encoded.

I hear I can use mod_Rewrite to do a 301 redirect? How would I do this. I am new to mod_rewrite.

I need to SEO my site badly and any help would be greatly appreciated.

I apologise for linking in this topic if that is not allowed, I just need to explain the situation and give examples.

Thanks for any help!

Are you using some sort of CMS to manage the websites content??

You don't need mod_rewrite help.

You simply need to add the old style URL's to a robots.txt file as exclusions. If you really want to use 301's simply add this at the end of your rewrite rules: [R=301]

I am using WHMCS which is a billing suite.

I tried adding [R=301] to the end of my rewrite rules and it made no difference .

How using rewrite rule could i redirect
knowledgebase.php?action=displaycat&catid=2
to
knowledgebase/2/Jargon_Buster

I added this rule to the bottom of my .htaccess file:

 
RewriteRule ^knowledgebase.php?action=displaycat&catid=2$  http://www.ufhosting.org/whmcs/knowl.../Jargon_Buster  [R=301,L]

But it does not work.

Like I said all help is much appreciated. Just need to get this working.
