My two cents.
Go to google.com/webmasters and submit your site there if you haven’t already.
For the pages having some keywords in the url (if it’s relevant) would help. Also keyword density is something that you need to bear in mind.
Try looking for some one way inbound links.
Make sure you have a sitemap and submit it to google.
Keep a tab on the webmaster page on google to view stats for your website and tweak it according to the keywords.
Hope this helps.
