This is a very quick 'n' simple vBulletin SEO hack. It's easy to apply and it's the one I have been using here on DaniWeb for the past couple of months. I was going to wait until we went vB 3.5 to release it but I might as well do so now ... Disclaimer: This is for vBulletin 3.0.x. It should not be too complicated to port to 3.5 with their hooks system, but I have no experience with 3.5 and therefore don't want to say one way or another. If you use this hack, please link to DaniWeb in your footer. This is a free hack, and it can make or break the traffic to your site. I don't know of any other freely available hacks like this one. Please help us out in exchange for releasing this!
STEP 1: Create an .htaccess file in your forum directory and put the following into it:

$vartext = preg_replace($search_array, $replace_array, $vartext);Please do not duplicate all or part of this code elsewhere. Thanks should go out to Xenon for suggesting to me that I can rewrite URLs from within this function. Thanks!! ... And, please, give credit where credit is due - if you use this hack, please link back.
