Quality Score is Google's one-to-ten rating of how relevant and useful your ad and landing page are: a higher score lowers what you pay per click and lifts where your ad shows.
Quality Score is Google's one-to-ten rating of how relevant and useful your ad and landing page are. It sits against each keyword in your account as a diagnostic, and a higher score usually lowers what you pay per click and helps your ad show in a better position.
Google builds the score from three components: expected click-through rate (how likely people are to click your ad when it shows), ad relevance (how closely your ad text matches what the person searched for), and landing page experience (whether the page they arrive on is relevant, fast and easy to use). Each is rated below average, average or above average, and together they roll up into the one-to-ten figure.
For a business owner, the practical effect is that relevance is rewarded with cheaper traffic. Two advertisers can bid the same amount, and the one with the higher Quality Score wins a better position while paying less per click. That is why tightly themed ad groups, ad copy that echoes the search, and a landing page that delivers on the ad's promise matter so much. It is one of the biggest levers on your cost per click, and a core part of what I work on in Google Ads management.
One honest caveat: the Quality Score you see is a simplified diagnostic, not the exact number used in the live auction. Google works out ad quality afresh every time your ad is eligible to show, using real-time signals the reported score cannot capture. So treat it as a guide to where your relevance is weak, not a scoreboard to obsess over.
Key points
- Quality Score is a 1-to-10 diagnostic reported per keyword, not a live auction number.
- It is built from three parts: expected click-through rate, ad relevance, and landing page experience.
- A higher score usually means a lower cost per click and a better ad position.
- Relevance is the lever: tightly themed ad groups, matching ad copy, and a good landing page all lift it.
- Two advertisers bidding the same can pay very different prices, the higher Quality Score wins.
- Chase relevance, not the number itself, the reported score is a guide rather than a target.
Frequently asked questions
Common questions about quality score.
Work on the three things Google measures. Tighten your ad groups so each one covers a single, specific theme, then write ad copy that echoes the exact search terms in that group. Make sure the landing page delivers what the ad promised, loads quickly and is easy to use on a phone. Improvements usually show over days to weeks, not instantly, because Google needs fresh click data to re-rate the keyword. If a keyword stays stuck at two or three despite all that, it is often a sign the search intent and your page are genuinely mismatched.
Not guaranteed, but the relationship is real and strong. A higher score improves your Ad Rank, which lets you hold a good position at a lower bid, so in practice better quality tends to buy cheaper clicks. It is not the only factor, though. Competition, your bid, the time of day and who else is in the auction all move the price too. So think of Quality Score as one of the biggest levers on cost per click, not a dial that sets it on its own.
Not in the same way. Performance Max does not report a keyword-level Quality Score, because you are not choosing the keywords, Google's AI is matching your assets to searches across its networks. The underlying idea still applies, relevant assets and a strong landing page help, but you do not have the same diagnostic to look at. If you want the transparency of Quality Score, a standard Search campaign is where you get it.
