Google Ads Quality Score is a diagnostic metric that helps advertisers understand how relevant and useful their Search ads and landing pages are compared with other advertisers. It can help identify areas where an ad, keyword, or landing page may need improvement. Understanding Quality Score is useful because it connects three important areas of the advertising experience: Expected CTR, Ad Relevance, and Landing Page Experience. However, Quality Score should not be treated as the main measure of campaign success or as a number that advertisers need to maximize on its own.
1. What is Google Ads Quality Score?
Google Ads Quality Score is a 1–10 diagnostic score available at the keyword level in Search campaigns. It provides an indication of how the quality of an ad and landing page compares with other advertisers for the same keyword. A higher Quality Score generally indicates that the ad and landing page are considered more relevant and useful to people searching for the keyword. Quality Score is not a KPI and should not be treated as a direct measure of campaign profitability. Instead, Google describes it as a diagnostic tool that can help advertisers identify areas where improvements may be useful. A keyword may also show “—” instead of a numerical score when there is not enough data from exact searches to calculate a Quality Score.
2. How Google Ads Quality Score Works
Quality Score is based on the combined performance of three components:
- Expected CTR
- Ad Relevance
- Landing Page Experience
Each component receives a status of Above average, Average, or Below average. These component-level assessments help advertisers understand where an ad experience may need attention. Quality Score also reflects historical performance associated with exact searches for the keyword. Changing a keyword’s match type does not directly change how Quality Score is calculated. It is important to understand that Quality Score is a diagnostic measurement. The 1–10 Quality Score itself is not an input in the ad auction. Google uses auction-time assessments of ad quality, along with other factors, when calculating Ad Rank.
3. The Three Components of Quality Score
3.1 Expected CTR
Expected CTR is the likelihood that your ad will be clicked when shown. Google uses this component to estimate how likely a user is to click the ad for a particular search. Expected CTR is not exactly the same as the CTR shown in your performance reports. It is a diagnostic assessment that helps indicate whether the ad is expected to attract clicks compared with other advertisers. If Expected CTR is Below average, the ad may not be sufficiently relevant or compelling for the searches where it appears.
3.2 Ad Relevance
Ad Relevance describes how closely your ad matches the intent behind a user’s search. The relationship between the keyword, ad copy, and user’s search query is important here.
For example:
| Element | Example |
|---|---|
| Ad Group | Running Shoes |
| Keyword | running shoes for men |
| Ad Copy | Men’s Running Shoes for Training |
| User Query | best running shoes for men |
The closer these elements are connected, the easier it is for the ad to communicate an appropriate response to the user’s search. Google recommends making ad text more directly relevant to user search terms and organizing different keyword themes into appropriate ad groups when necessary.
3.3 Landing Page Experience
Landing Page Experience describes how relevant and useful your landing page is to people who click your ad. The landing page should deliver what the ad promises and should be closely related to the user’s search. For example, if an ad promotes discounted running shoes, the landing page should make those shoes and the advertised offer easy to find. A relevant landing page, consistent messaging, intuitive navigation, and a good experience across devices can all contribute to a better landing page experience.
4. Understanding Quality Score Statuses
Each Quality Score component can receive one of three statuses:
- Above average — The component is performing better than the comparison benchmark.
- Average — The component is around the comparison benchmark.
- Below average — The component may need improvement.
These statuses are particularly useful because they show which area deserves attention.
For example, if a keyword has:
| Component | Status | What to Investigate |
|---|---|---|
| Expected CTR | Below average | Is the ad sufficiently relevant and compelling? |
| Ad Relevance | Average | Does the ad closely match the keyword and search intent? |
| Landing Page Experience | Above average | Is the landing page already providing a strong experience? |
Instead of making changes everywhere, the advertiser can focus on the component showing the greatest opportunity for improvement.
5. How to Improve Google Ads Quality Score
The best way to use Quality Score is to improve the underlying areas represented by its three components rather than simply trying to increase the 1–10 number.
5.1 Make Ads More Relevant to Keywords
If Ad Relevance is Average or Below average, focus on the connection between the user’s search, keyword, and ad.
- Ad Groups: Organize different keyword themes into appropriate ad groups so that the ads can remain closely related to the searches they target.
- Ad Copy: Make the language of the ad directly relevant to the keyword and the user’s intent.
- Keywords: Use keyword themes that can be meaningfully addressed by the associated ad copy.
- Search Query: Consider the actual searches that trigger your ads and whether your ad provides a relevant response to those searches.
- Google specifically recommends matching ad language more directly to user searches and separating different keyword themes into better-aligned ad groups when appropriate.
5.2 Improve Expected CTR
When Expected CTR is Average or Below average, consider whether the ad gives users a clear reason to click.
Useful approaches include:
- Make the ad relevant to your target audience.
- Make the ad match the intent of the keyword.
- Highlight a relevant benefit or value.
- Experiment with different calls to action.
- Make the ad more specific where appropriate.
Google notes that advertisers should balance stronger click-through performance with their actual business goals. A more specific ad can sometimes attract fewer clicks while producing more valuable traffic. The objective should therefore be relevant clicks, not simply increasing CTR at any cost.
5.3 Improve Landing Page Experience
When Landing Page Experience is Average or Below average, examine whether the page delivers what users expect after clicking the ad.
- Specific Landing Page: Use a landing page that closely matches the user’s search and the promise made in the ad.
- Consistent Messaging: The message and offer presented in the ad should be reflected clearly on the landing page.
- Mobile Friendly: Make sure users can easily read, navigate, and interact with the page on mobile devices.
- Fast Loading: A page that takes too long to load can create a poor user experience. Keep the page efficient and accessible.
Google recommends making sure the landing page matches the user’s searches and keeping the messaging consistent from the ad to the landing page.
6. Quality Score vs Ad Rank
Quality Score and Ad Rank are related to ad quality, but they are not the same thing.
Quality Score is a 1–10 diagnostic metric that helps advertisers understand areas such as Expected CTR, Ad Relevance, and Landing Page Experience.
Ad Rank is used in the auction to determine whether an ad is eligible to show and, if eligible, where it appears relative to other eligible ads. Ad Rank considers multiple factors, including the bid, auction-time ad quality, Ad Rank thresholds, competition, search context, and expected impact of assets and other ad formats.
Therefore, it is incorrect to think of Quality Score as a direct Ad Rank score.
The important distinction is:
Quality Score = diagnostic tool
Auction-time ad quality = one of the factors considered in Ad Rank
Ad Rank = determines eligibility and position in the auction
7. Quality Score vs Max CPC Bid
Quality Score and Max CPC bid are also separate concepts.
Max CPC bid is the maximum amount an advertiser is generally willing to pay for a click under the applicable bidding setup.
Quality Score is a diagnostic assessment of ad quality.
Actual CPC is determined through the auction and can be lower than the Max CPC bid. Google considers auction-time ad quality, the bid, Ad Rank thresholds, competition, search context, and other factors when determining Ad Rank and actual CPC.
Therefore, a Quality Score of 10 does not guarantee a particular CPC, just as a specific Max CPC bid does not guarantee a particular Quality Score.
8. How to Check Google Ads Quality Score
You can review Quality Score and its components in your Google Ads account.
- Open the Keywords section of your Search campaign.
- Select the Columns option.
- Choose Modify columns.
- Open the Quality Score category.
- Add:
- Quality Score
- Expected CTR
- Ad Relevance
- Landing Page Experience
- Apply the columns to view the diagnostic information alongside your keywords.
Use the component information to identify areas that may need attention rather than focusing only on the numerical Quality Score.
9. Common Quality Score Mistakes
Several common assumptions can lead advertisers to focus on the wrong things.
- Treating Quality Score as a campaign KPI.
- Assuming a higher Quality Score automatically guarantees a higher ad position.
- Assuming Quality Score itself is an auction input.
- Confusing Expected CTR with actual CTR.
- Confusing Ad Relevance with Landing Page Experience.
- Sending users to a landing page that does not closely match the ad.
- Focusing on the 1–10 score instead of the component-level diagnostics.
- Treating Max CPC bid and Quality Score as the same type of measurement.
Google recommends using Quality Score to identify areas for improvement rather than trying to optimize the score itself.
10. Why Google Ads Quality Score Matters
Quality Score matters because it gives advertisers a practical way to diagnose the relationship between their keywords, ads, and landing pages. Instead of simply seeing that an ad is performing poorly, advertisers can examine whether the potential issue is related to:
- Expected CTR
- Ad Relevance
- Landing Page Experience
These insights can then guide improvements to ad messaging, keyword-to-ad alignment, and landing-page relevance. However, Quality Score should be considered alongside more important performance measurements such as CTR, conversions, conversion rate, cost, and business results.
11. Conclusion
Google Ads Quality Score is a 1–10 keyword-level diagnostic tool that helps advertisers understand the quality and relevance of their Search advertising experience. Its three main components are Expected CTR, Ad Relevance, and Landing Page Experience. By examining the status of each component, advertisers can identify where their ads, keywords, or landing pages may need improvement. The most important point is that Quality Score itself is not something to chase as a standalone number. The better approach is to improve the underlying experience: make ads relevant to searches, give users a clear reason to click, and send them to useful landing pages that match what the ad promises. Quality Score becomes most useful when it is treated as a diagnostic guide, while actual campaign performance is judged through meaningful business and advertising results.
