I like this video as it features the living legend that is Hal Varian and he explains the quality score algorithm brilliantly

Google Quality Score Summary: The Google AdWords system calculates a ‘Quality Score’ for each and everyone of the keywords in your account. The system looks at a variety of ranking factors (click through rate’s key) to measure how relevant the keyword is to the ad text used and then to the user’s search query. A keyword’s Quality Score updates in relative real time closely related to its performance. In general, a high Quality Score (measured out of 10 with 7+ generally being considered ‘good’) means that your keyword will trigger ads in a higher position and at a lower cost per click (CPC)
