Google's Information Gain Score: Enhancing Search Results Based on User Interests

The Information Gain Score is a metric used by Google to rank search results. It measures how much more information a resource can provide to a visitor who has already read other resources on the same topic. Pages that offer additional valuable information that wasn't found in previously viewed pages are likely to receive a higher score and, consequently, may be ranked higher in search results.

Google's Information Gain Score works by:

1. Identifying the first set of pages displayed to the visitor.
2. Determining if the pages share a common topic with information previously provided to the user.
3. Calculating a score for each new page in the second set of pages, indicating whether that page contains information not found on the pages of the first set.
4. Selecting and/or ranking the new documents to provide to the user based on their respective scores.

As the visitor views more pages, the second set of pages may be re-ranked based on new Information Gain Scores. Pages are increased in ranking if they add significant information for a visitor and downgraded if they do not.
