Ask.com organic
Ask.com organic results come from its Teoma technology, currently known as ExpertRank. Ask states that ExpertRank goes beyond link popularity to determine popularity among pages considered to be experts on a search query topic. Its subject-specific popularity identifies topics (also known as clusters), giving a unique editorial flavor to its results. As with Yahoo and MSN Live Search, optimize for organic visibility using traditional SEO tactics. Ask Editorial Guidelines provide information on how Ask generates its search results as well as tips for getting indexed. Ask powers Lycos, iWon and HotBot.

Since Ask gets its sponsored search results from Google, we won't get any help here.
