I think most of us understands the algo of Google listing: Linking from high PR, optimized keywords in Google, etc.

What is the algo for Yahoo and MSN? They don't have PR for measurement. Though they count links but on what basis do they count and value it?

I tried looking around for such stuff and the only thing I found was just on-page optimization for Yahoo and MSN.

Anyone care to share on that?

The algo of google is dependent on Backlinks. More Backlinks better in SERP's

The algo of Yahoo/MSN is more dependant on On page factors like Hx, Title, Bold, underline.

The algo I meant they give higher weightage factor to those.
