Simple Rewrite Rule SEO

[socalnate]

I'm the webmaster for egamestorm.com...been having problems with SEO for my game pages. Here's my setup:

 

Example: LINK TO HERE

http://egamestorm.com/portal/18686

 

IS MOD_REWRITED

 

Options +FollowSymlinks

RewriteEngine On

RewriteBase /portal/

RewriteRule ^([0-9]+) game.php?id=$1

 

WEB ADDRESS BAR OUTPUTS: http://egamestorm.com/portal/18686

 

Any suggestions on SEO?  Trying to maximize indexing but google isn't getting all of my pages without me submitting a sitemap.

 

Thanks!

I would suggest you to include the game name inside the URL, it will be easier to get indexed on search engine.
