Google Ads Quality Score: What It Is and How to Improve It

Google calculates this metric by evaluating three distinct areas of your campaign. Each component receives a status of Above Average, Average, or Below Average. This breakdown allows you to identify exactly where your search marketing strategy needs adjustment. If you see a low overall number, these sub-scores tell you if the problem lies with the creative copy, the keyword selection, or the website itself.

Expected click-through rate (CTR)

Expected CTR measures how likely someone is to click your ad when it appears for a specific keyword. This is not your actual CTR, but rather a prediction based on how that keyword has performed in the past across all advertisers. If your ad looks like it will satisfy the user’s intent better than others, your expected CTR will likely be higher. It ignores factors like ad position and assets, focusing purely on the keyword-to-ad relationship.

Ad relevance

Ad relevance identifies how closely your ad matches the meaning behind a user’s search query. For instance, if a user searches for ‘organic roasted coffee beans’ and your ad only mentions ‘coffee,’ the relevance might be considered Average or Below Average. Highly specific ads that mirror the search term directly tend to perform better in this category. It ensures that users are not shown irrelevant content that wastes their time.

Landing page experience

Landing page experience determines how helpful your website is to the person who clicked your ad. Google looks for a clear connection between what the ad promised and what the page delivers. A high-quality landing page is easy to navigate, features original content, and loads quickly on both mobile and desktop devices. If a user clicks an ad for a specific product but lands on a generic homepage, the experience score will likely drop.

Quality Score directly influences your Ad Rank, which is the value used to determine where your ad shows up on the search results page. While your bid is a major factor, the quality of your ad acts as a multiplier. In a typical account, a keyword with a score of 9 or 10 will often pay significantly less for the top position than a keyword with a score of 3 or 4. This system rewards advertisers who provide a positive user experience.

Consider a scenario where a small boutique competes with a large retailer. The retailer might bid $5.00 with a Quality Score of 2, while the boutique bids $2.00 with a Quality Score of 9. Because the boutique’s ad is much more relevant and helpful, Google may place them higher than the retailer. This levels the playing field for businesses that focus on precision rather than just raw spending power.

To boost your expected CTR, you must make your ads more appealing and professional. Using all available ad assets, such as sitelinks, callouts, and structured snippets, increases the physical size of your ad and provides more reasons for users to click. These assets provide extra information that can distinguish your brand from competitors.

Another effective method involves testing different calls to action (CTAs). Instead of a generic ‘Buy Now,’ try using ‘Get 20% Off Today’ or ‘Browse Our Autumn Collection.’ Specificity often leads to higher engagement. In a typical campaign for a service provider, highlighting a ‘Free Consultation’ usually results in a better expected CTR than just listing the service name. You should also ensure that your most important keywords appear in the headlines.

• Include your primary keyword in Headline 1.
• Use active verbs like ‘Save,’ ‘Discover,’ or ‘Join.’
• Highlight unique selling points like ‘Free Shipping’ or ’24/7 Support.’
• Utilize the Display URL paths to reinforce the topic.
• Test at least three responsive search ads per ad group.

A common misconception is that the 1-10 number you see in your account is used exactly as it is during every search auction. In reality, Quality Score is a retrospective diagnostic tool. When a search actually happens, Google uses ‘Auction-time Quality’ signals. These include the user’s location, the time of day, the device they are using, and the context of their search query. The 1-10 score is simply an aggregated estimate of those real-time factors to help you improve your account.

Because the 1-10 score is not a direct input, you should not obsess over changing a 7 to an 8 if your conversion rates and costs are already meeting your goals. Use it as a guide to find keywords that are underperforming. If a high-volume keyword has a score of 3, it is a clear signal that you are losing money due to poor relevance or a bad landing page, and that is where you should focus your optimization efforts.

Your landing page must be a direct continuation of your ad. If your ad mentions a ‘Blue Leather Sofa,’ the landing page should show that exact product, not a general furniture category. Transparency is also vital. Make sure your contact information and privacy policy are easy to find. This builds trust with both the user and the search platform.

Technical performance cannot be ignored. Google recommends that your Largest Contentful Paint (LCP) occurs within 2.5 seconds of when the page first starts loading. A slow site causes users to ‘bounce’ or return to the search results, which signals to the platform that your page was not helpful. For a Shopify store selling apparel, for example, optimizing image sizes is often the fastest way to improve this component.

• Ensure the page is fully responsive for mobile users.
• Match the headline of the page to the headline of the ad.
• Reduce the number of pop-ups that interfere with navigation.
• Improve server response times to decrease page load speed.
• Provide clear and easy-to-use navigation menus.

One of the most frequent errors is using overly broad ad groups. If you put 50 different keywords into one ad group, it is impossible to write a single ad that is relevant to all of them. This dilutes your ad relevance. Instead, group keywords into tight themes of 5-10 related terms. This allows you to tailor the ad copy to the specific intent of that group.

Neglecting negative keywords is another mistake. If you sell ‘premium watches’ but show up for ‘free watch wallpapers,’ your CTR will plummet because those users aren’t looking to buy. Regularly auditing your Search Terms Report helps you exclude these irrelevant queries, which protects your expected CTR over time. Forgetting to update broken links during a website migration can also lead to a sudden drop in landing page experience scores.
