Quality Score
Google Ads' 1–10 diagnostic of ad, keyword and landing page relevance.
SEM
Definition
Quality Score estimates expected click-through rate, ad relevance and landing page experience for a keyword.
It is a diagnostic aggregate rather than the exact value used in the live auction.
Why it matters
Higher relevance lowers the price of the same position, so Quality Score work compounds directly into media efficiency.
How to apply it
- Tighten ad groups so ad copy can mirror the query.
- Align landing page headline with the ad headline.
- Prune queries the landing page cannot genuinely serve.
