Bill Slawski notes new Google patent applications related to algorithims built to determine how effective an online advertisement, using methods much more complicated than a simple click-through rate. Hurray to Bill for finding that one.

A trio of patent applications from Google look at estimating the likelihood that an advertisement is a good one, in a method that goes beyond counting click-through-rates (CTR).They supply an extremely detailed list of factors that might go into a quality score, as well as details of different statistical models that might be generated from gathering data about those different factors.
