How do I make spider friendly urls, that say the keywords of the post in the url
 

I see some vb forums have the major words from the post in the actual url.
Like this forum http://www.askmehelpdesk.com/interne...on-245982.html how do I do that?

Thanks!:confused:

There are a number of modifications that do this, some are paid mods such as vBSEO

Search the mod section here at vBulletin.org though and you'll find many free ones that do the same wuch as tFSEO and Zoints SEO

Those are not spider friendly URL's, they are human friendly URL's. For a SE spider the URL doesn't make a difference.
