Google and other search engines seem to dislike basic directory. One with just links and no useful contents. Here are some tips I think one can use to enahance a directory. Please add your suggestion to this thead: 1. Contents of about 200-400 words at the begining of each category (see deeplylinked.com for what I mean) 2. Unique categories (don't just use the category creation dump script owner provides) 3. Have only absolutely necessary categories, creating lots of empty category is not good.
