A Search Engine Roundtable post, reports the thread over at WebmasterWorld discussing an updated Google patent named Information retrieval based on historical data, which highlight following two out of several abstracts:
- How does Google know when a site has changed enough where they should drop all the past trust and link popularity associated with that site?
- We heard it before, "Don't get links too quickly" because it seems unnatural. Well, here it is on paper.
According to Google itself:
Stale content refers to documents that have not been updated for a period of time and, thus, contain stale data (documents that are “no longer updated, diminished in importance, superceded by another document“).
Bill Slawski summarizes the patent:
The Constitution of the United States is an old document, but it’s not stale. A news article about the “World Series” from 1918 may not be what a baseball fan wants to see when searching for “World Series” this October.
