What is the best way of inserting keywords into a social networking site

[seoworx123]

We have a social networking site called Yookos (www.yookos.com). As per the norm, many of the pages of the site carry user generated content and can only be accessed by the users themselves.

i created a keyword list that our technical person the uploaded onto the site but SEOmoz shows that these keywords cannot be picked up.
What is the best way to make sure that our site is also picked up via search engine searches.

Make sure you have a number of publicly accessible pages that really drive home your theme with good meta titles, h tags, image alt tags and key word repetition in your copy.  This could be the home page, welcome pages or about pages.  Im not sure of the target market for your network but you could plan separate landing pages for each user type you hope to attract.
A company blog never hurts also!

I would second FDFPres' suggestions. The site needs to have content accessible to the public which Google can also crawl and index. I would choose content types that best fit your target keywords, audience and brand!
