In the first part I posted some numbers, do you remember them? They were the percentage that each SE held of the search market in 2007.
Here, let's refresh your memory:
Google: 50%
Yahoo: 30%
Live: 10%

is less biased-toward revelance and links than Google, but it still analyzes a site's trust and authority to rank it.
About its way to rank websites:
  • Gives a lot of weight to a site's metadata
  • Sometime, it's index is manually edited to avoid spam entries

  • Poor at links and revelance analysis
Live Search takes it's popularity from Micrsoft predominance in the OS world and as a default SE in Internet Explorer

The Forgotten One

Ask Jeeves holds a mere 5% of the search engine market share. But 5% of bilions of searches everyday is still alot...
About its way to rank websites:
  • Biased toward link revelance and
  • Topical authority
  • As Google, it advantages off-page optimization more than on-page
