Quality Score
Quality Score is a diagnostic metric in Google Ads, rated 1 to 10, that estimates how relevant your keyword, ad, and landing page are to a searcher. It is built from three components: expected click-through rate, ad relevance, and landing page experience. Higher scores generally lower your cost per click and improve where your ads appear.
Key Takeaways
- Quality Score is a diagnostic metric in Google Ads, rated 1 to 10, estimating relevance to a searcher.
- It is built from three components: expected click-through rate, ad relevance, and landing page experience.
- A higher Quality Score generally lowers your cost per click and improves ad position.
- Quality Score is a symptom of relevance, not a lever you optimize directly.
- Improving the underlying ad relevance and landing page experience is what actually raises the score.
How It Works
Quality Score is Google's estimate of how relevant your keyword, ad, and landing page are to the person searching. It combines three signals: expected Click-Through Rate, which predicts how likely people are to click your ad, ad relevance, which measures how closely your ad matches the query, and landing page experience, which judges how useful and fast the destination page is.
The score feeds into Ad Rank, the value Google uses to order ads in the auction. A higher Quality Score can win a better position while costing less per click, because Google rewards relevance rather than simply the highest bid.
The key is to treat Quality Score as a diagnostic, not a target. You do not raise it by staring at the number, but by tightening ad copy to match keywords, improving the landing page, and pruning irrelevant traffic with Negative Keywords so your ads show mostly on searches they genuinely fit.
Why It Matters
A strong Quality Score lets you win better ad positions while paying less than competitors for the same clicks. It rewards genuine relevance, so improving it usually improves user experience and conversion rate at the same time.
Example
A dentist runs an ad group where one ad points searchers for teeth whitening to a generic homepage. Quality Score sits low and clicks are expensive. The team writes a whitening-specific ad and sends clicks to a matching whitening page. Ad relevance and landing page experience improve, the Quality Score rises, and the same ad position now costs noticeably less per click.
Common Mistake
Treating Quality Score as a number to optimize directly. It is a symptom, not a lever. Chasing the score instead of fixing the underlying ad relevance and landing page experience wastes time and rarely moves it.
Frequently Asked Questions
How is Quality Score calculated?
Quality Score combines three components: expected click-through rate, ad relevance, and landing page experience. Google rates it from 1 to 10 as a diagnostic of how relevant your keyword, ad, and landing page are to the searcher.
Does Quality Score affect how much I pay?
Yes. A higher Quality Score feeds into Ad Rank and generally lowers your cost per click, letting you win better positions while paying less than competitors bidding on the same keywords, because Google rewards relevance.
How do I improve a low Quality Score?
Do not chase the number directly. Improve the underlying pieces: tighten ad copy to match your keywords, improve the landing page speed and relevance, and use negative keywords so ads show mostly on searches they genuinely fit.
