Bill Slawski has come across some patent applications from Google that look to detail how they calculate quality score. Interesting stuff.

[seobythesea.com...]

Here are some of the factors.

- How many times a user selects a given ad in a given session.
- A duration of time, from an ad result selection, until the user issues another search query. This may include time spent on other pages (reached via a search result click or ad click) subsequent to a given ad click.
- A ratio of the time, from a given ad result selection until the user issues another search query, as compared to all other times from ad result selections until the user issued another search query.
- Time spent, given an ad result selection, on viewing other results for the search query, but not on the given ad result.
- How many searches (i.e., a unique issued search query) that occur in a given session prior to a given search result or ad selection;
- How many searches that occur in a given session after a given search result or ad selection.
- Rather than searches, how many result page views that occur for a given search query before a given selection. This can be computed within the query (i.e., just for a unique query), or for the entire session;
- Rather than searches, how many search result page views that occur for a given search query after this selection. This can be computed within the query (i.e., just for the unique query), or for the entire session;

This is good stuff!

Thank you for sharing!

Way better description of quality score than I was ever given by the google reps.

You should thank Bill. Keep in mind none of this is definite, but it seems like the patents probably apply to quality score.
