What is Quality Score?
Quality Score is a metric in Google Ads that assesses the relevance and quality of your keywords, ads and landing pages. You use it to understand how well your ads match users' intentions, and how effectively you deliver the experience they're looking for. The score runs from 1 to 10, where 10 is the best, and is therefore a clear signal of how competitive your account is in Google's ad auction.
The metric works as a diagnostic tool because it helps you identify weak points in your account and improve them. If your landing page doesn't convert, or if your ad doesn't speak directly to search intent, a low Quality Score can reveal it. In practice, the score reflects Google's assessment of how much value you create for the user, not just whether you pay for clicks.
How do you use Quality Score?
You use Quality Score as a benchmark when optimising your Google Ads. It's based on three core elements: expected click-through rate (CTR), ad relevance and landing page experience. When you analyse your score, you can see each part rated as “Above average”, “Average” or “Below average”. That makes it clear where you should focus to increase relevance.
Expected click-through rate tells you whether your ad copy appeals to users. A high CTR indicates that your message meets the need. Ad relevance measures how well your keywords fit the ad, while landing page experience is about usability and the relevance of the content. Design, speed and UX all play a role here. It therefore pays to draw on knowledge from digital design and content production when you work on improving this part of the score.
Why is Quality Score important?
A high Quality Score means that Google considers your ads more relevant and user-friendly than your competitors'. That gives you several advantages: you pay less per click, your ad gets better positions, and it's easier to achieve a high Ad Rank. In short, the system rewards quality, not just budget.
So your results in search ads don't depend solely on how much you bid, but also on how well you match the user's needs. That makes the metric central to an effective SEM strategy, because you reduce waste while creating more value per click. In other words, you get better performance without your costs necessarily going up.
What types and variants are there?
Quality Score is mainly used in Google Ads, especially in search campaigns, but you'll see similar assessments on other platforms such as Microsoft Ads and Yahoo. The basic idea is the same: an internal quality measure at ad, keyword and landing page level. When you work with large accounts, you'll only find the score for keywords that have triggered actual ads, because the data collection requires history.
Although most people think of Quality Score in connection with search ads, the principle affects your entire campaign hierarchy. Relevance between keyword, ad group and landing page is closely linked, so you should keep a structured setup throughout the account. That strengthens both the score and overall performance.
How do you work with Quality Score in practice?
You'll find your Quality Score in the keywords overview in Google Ads. Here you can see both the score from 1 to 10 and the three component ratings. The key is ongoing optimisation — you need to test and adjust ads, keywords and landing pages until all the components work together. When you discover that a keyword has low relevance, you should either change the ad copy or move the keyword to a more focused ad group.
An example could be:
You can also improve expected click-through rate by testing different ad headlines and descriptions. Use data from previous campaigns to choose the messages that most often drive engagement. In some cases, visual elements such as short video clips or infographics on the landing page can contribute to a better experience, because they aid understanding and hold attention — an area where collaboration between video and design teams can make a concrete difference.
What should you be aware of?
Although Quality Score is an important indicator, it's not the only factor that determines your Ad Rank. Your bid, your ad extensions and the overall context also play a role. So don't focus solely on the number, but use it as a benchmark for improvement. What matters most is actual performance — click-through rates, conversions and ROI show whether the work pays off.
Remember that the score is assessed continuously. Changes in the industry, level of competition and search behaviour can make your score fluctuate. So schedule regular reviews of your campaigns so that you can adapt messages and content before results drop. In practice, this means that working with Quality Score isn't a one-off task, but a continuous process where data and performance need to be closely linked.
