How Google May Identify Navigational Queries and Resources, Bill Slawski, SEO by the Sea (Dec 9)

“A patent granted to Google last week explores how to use query sessions to identify Navigational Queries and Navigational Resources.”
“If Google decides that a query is a navigational query, and a result for it is a navigational result, the patent tells us that the page identified as a navigational result might be re-ordered in search results so that it is “always shown on a first page search results provided for the user session.””
