Quality score

From The Yaffe Center

Quality score is a measure of the relevance of the keyword for the ad. It is measured for each of the keywords used by the advertiser and these scores are frequently updated to reflect the performance of the advertiser’s keyword in generating ads. Quality score is an important factor in calculating ad rank and determining the relative position of the ad in the search page.

A higher quality score indicates that an ad can appear at a higher position at a potentially lower CPC. Quality score can be improved via several optimization techniques.
