Ask's ExpertRank algorithm provides relevant search results by identifying the most authoritative sites on the Web. With Ask search technology, it's not just about who's biggest: it's about who's best. 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. |

Metasearch searches multiple engines - this means that instead of getting the best results one search engine has to offer, you'll be getting the best combined results from a variety of engines, and not just any engines, but industry leading engines like Google, Yahoo! Search, Live Search, Ask.com, About, MIVA, LookSmart and more |

| Jayde - Business to Business Search Engine |
http://www.jayde.com |
The Jayde Search Engine provides only one result per website … but, every result contains a Company Profile with organized links to internal pages within that website. Each Company Profile is organized into what we call a ContentMap for that site. Jayde also has a categorized directory containing all of it's business listings. Jayde is powered by a distinct algorithmic concept called ClickRelevance. ClickRelevance is a unique concept in search and is the most effective way to provide relevant results to searchers. ClickRelevance ranks all categories and search results by those which are clicked the most by unique searches. When multiple people click on similar listings for the exact same search phrase or within a particular category the ClickRelevance algorithm reorganizes the results for that term so that the most clicked listings gradually move up and the least clicked move down in the results. |
