As with all other engine's, teoma looks at the structure of the web, and the structure of your site. The closer that you can get the structure of your site, to fit teoma's view of the web the better.
Structure in the context used: relates to the navigation and content distribution accross the site, with as WBF mention's the necessary related incoming links to back it up, within a tight as possibly related structure, so that they reinforce the content of the site.
Dependant on the scale of your site, it maybe worth a rethink, this would also help in most other search engine's for ranks. Its not so much optimization, but a well planned out web site promotional campaign.
