Quality Score

Last updated: 2026-06-13

What it is

Quality Score is Google Ads' way of summarising, at the keyword level, how useful your ad is likely to be to the person searching. It is reported as a single number from 1 (poor) to 10 (excellent), and it is built from three components that Google rates as "Below average", "Average" or "Above average":

• Expected click-through rate (CTR) — how likely your ad is to be clicked when it shows for a given keyword, relative to others.
• Ad relevance — how closely your ad copy matches the intent behind the keyword.
• Landing-page experience — how relevant, useful, fast and easy to navigate your landing page is once someone clicks.

Quality Score itself is a diagnostic, not a live number used in the auction. The underlying real-time quality signals, however, feed directly into Ad Rank, which decides whether your ad shows, where it shows, and what you pay.

Why it matters

Quality Score matters because it has a direct effect on cost. In the Google Ads auction, your cost per click (CPC) is not simply your bid — it is calculated from the bid and quality of the advertiser ranked just below you. When your quality is high, you can win a strong ad position with a lower bid, so a well-optimised account often pays less per click than a careless one chasing the same keywords.

The reverse is also true: low Quality Score keywords cost more and may stop showing entirely. That makes Quality Score one of the most practical levers in any pay-per-click (PPC) campaign, because improving it lowers cost and lifts visibility at the same time.

In practice

Improving Quality Score means working on the three components Google actually reports:

• Tighten ad relevance — group closely related keywords together and write ad copy that uses the searcher's actual language. A broad ad group covering dozens of unrelated terms almost always dilutes relevance.
• Lift expected CTR — make the offer in the headline clear and specific, and use ad extensions so the ad takes up more space and answers more questions.
• Improve landing-page experience — send clicks to a page that matches the ad's promise, loads quickly, works on mobile, and makes the next step obvious. A fast, on-message landing page is often the biggest unlock.

Because these signals reflect genuine relevance, the same changes that raise Quality Score usually raise conversion rates too — which is why landing-page work sits at the centre of disciplined account management.

Related terms

Quality Score sits alongside several other paid-search concepts:

• CPC (cost per click) — the amount you pay per click, which Quality Score helps push up or down.
• PPC (pay-per-click) — the advertising model Quality Score lives inside.
• PPC Management — the ongoing work of optimising bids, ads and landing pages to keep scores high.

Frequently asked questions

What is a good Quality Score?

Quality Score runs from 1 to 10, where 10 is best. Scores of 7 and above are generally considered healthy, while keywords scoring 1 to 4 usually signal weak ad relevance or a poor landing-page experience that is worth fixing.

Does Quality Score affect how much I pay?

Yes. Quality Score is one of the inputs Google uses to calculate Ad Rank, and a higher score can let you win the same ad position at a lower cost per click than a competitor with a lower score.

How do I improve my Quality Score?

Improve the three components Google reports: tighten ad relevance by grouping closely related keywords with matching ad copy, lift expected click-through rate with clearer offers, and improve the landing-page experience with fast, relevant, mobile-friendly pages that match the ad's promise.

In short

Quality Score is Google's shorthand for "how relevant is this ad?" — and improving it is one of the few moves in paid search that lowers cost and improves results at once.
