An example of detail page url is:

Code:
http://www.abcdir.com/detail/834/gamersgate.html
Where gamersgate is the tilte. If you have non-english text, the detail page url may look something like:

Code:
http://www.abcdir.com/detail/314/白猫.html
The above two examples explain that both url is not optimized for seo. Here i have better detail page url for them:

Code:
http://www.abcdir.com/detail/834/gamersgate-buy-and-download-game-online.html 
http://www.abcdir.com/detail/314/白猫-shiroi-neko-white-cat.html
Notice that now the url become more meaning full. I believe search engine will be happier with the new pattern.

How to do this? Here is the detailed instruction:
