not that anyone really uses ask.com but how would you get them to index a site. I've tried submitting my url to them but nothing. I've heard that all their submissions are reviewed by humans before being added. How would you get ask.com to index a site?
Ask's ExpertRank algorithm provides relevant search results by identifying the most authoritative sites on the Web. Our ExpertRank algorithm goes beyond mere link popularity (which ranks pages based on the sheer volume of links pointing to a particular page) to determine popularity among pages considered to be experts on the topic of your search. This is known as subject-specific popularity. Identifying topics (also known as "clusters"), the experts on those topics, and the popularity of millions of pages amongst those experts -- at the exact moment your search query is conducted -- requires many additional calculations that other search engines do not perform. The result is world-class relevance that often offers a unique editorial flavor compared to other search engines.

I would use the same methods that I use to rank well in the three major search engines to get ask.com to index me. i.e. get more links. Since they send so little traffic my way, catering to the way they index and rank a site just isn't worth my time. Gary
