Search Engine Rankings
Backlinking - The more you link back to your corporate domain you could get ranked higher in the search engines. Search engines like "backlinks" (for now anyway). Make sure you link from keywords that are meaningful in your posts. For instance if one of your keywords is "red lipstick" then link back to a page on your site from that keyword.
Categories - Flag each post or "tag" them with a popular keyword(s) or categories for the search engines to key on as well. Notice the (s) above? Put your posts in multiple categories so they can have multiple tags. The more the merrier.
