This document discusses common misconceptions about Google's Quality Score metric. It addresses six misconceptions: 1) There is not a single Quality Score, but multiple scores used for minimum bids and ad ranking; 2) Changing keyword match types does not impact Quality Score; 3) Higher ad position does not necessarily benefit Quality Score; 4) High click-through rate does not guarantee high Quality Score; 5) Optimizing an account does not reset the history used to calculate Quality Score; and 6) Pausing ads does not directly penalize Quality Score. The document provides facts to clarify each point and dispel these misconceptions.
