Quality Score
Google's 1–10 estimate of your ad, keyword and landing page relevance.
Quality Score combines expected CTR, ad relevance and landing page experience. It influences your ad rank and your actual CPC.
A Quality Score of 6 or below on commercial keywords usually signals a mismatch between keyword, ad copy and landing page.
MyAd reports Quality Score components across all keywords and prioritises the ones where an improvement will actually move cost.
