Hi there guys i am working on a site which is made up of cgi it is also a shop does anyone have any ideas on a way i can SEO it up and start getting it listed

Search engine spiders don't execute cgi scripts, so you'll need to have a lot of good content that's spiderable.

You'll also need to work on getting links to the site from other sites that share the site's same topic. Promote the site just like you would any other site.
