Here is something fresh and Interesting from google. They now want to rank webpages in proportion with the traffic on that page. http://appft1.uspto.gov/netacgi/nph...&S1=20070088693&OS=20070088693&RS=20070088693 Apart from this, there are three new patents by google. - Document Scoring Based on Query Analysis. - Document Scoring Based on Link-Based Criteria. - Document Scoring Based on Document Inception Date.
Read the first line carefully. looks like its relevant to AdSense/AdWords patent and not a core search algirthm patent. Pierce
