You need keywords which you would like to promote. Once you chose them, something like "Vbulletin Modifications Board" try to add your Website into Linkdirectories. Linkdirectories are something like (submiturl123.com). It is very important that you add your website into the matching categories as google counts content related links.

Also try adding your Keywords into the VB-Page Description on the bottom of your website. on my site it is "WoW Hacks, Cheats". You get lot's of pages for that Keyword pointing to your frontpage. Google then thinks your website is important for those Keywords and automatically ranks you up higher.
