What Is Google Ads Quality Score?
Google Ads Quality Score is a diagnostic score from 1 to 10 that shows how the quality of your Search ad experience compares with other advertisers competing for the same keyword.
Google evaluates three components when determining Quality Score: expected click-through rate (CTR), ad relevance, and landing page experience. Each component can be rated Above Average, Average, or Below Average, helping you identify where the connection between the search, ad, and landing page may need improvement.
A higher Quality Score can indicate stronger relevance and expected user experience, while a lower score can help uncover specific areas worth investigating. However, Quality Score should be used as a diagnostic tool rather than treated as the primary KPI for campaign success.
How Google Ads Quality Score Is Calculated
Quality Score is based on the combined assessment of three diagnostic components: expected click-through rate, ad relevance, and landing page experience. Google compares each component with other advertisers whose ads competed for the same keyword over the previous 90 days.
Rather than thinking of Quality Score as a simple formula you can manipulate, use these three components to understand where the search-to-ad-to-landing-page experience may be weak.
The Three Main Google Ads Quality Score Factors
Each Quality Score component examines a different part of the search experience. Expected click-through rate evaluates the likelihood of a click, ad relevance looks at how closely the ad matches search intent, and landing page experience considers the usefulness of the page after the click.
Looking at these components individually can help you identify where the connection between the search, advertisement and landing page needs improvement.
How Quality Score Affects Google Ads Performance
Quality Score can help diagnose weaknesses in the relationship between a user’s search, your ad and the landing page, but it should not be treated as a standalone measure of campaign success.
Strong component ratings generally indicate better alignment across the search experience. However, a high Quality Score does not guarantee conversions, profitability or a strong return on ad spend. Those outcomes depend on additional factors such as targeting, bidding, offer quality, conversion tracking, landing-page effectiveness and the economics of the business.
Does a Higher Quality Score Lower Your Google Ads CPC?
Quality Score and cost per click are related to ad quality, but advertisers should be careful about treating the 1–10 Quality Score as a direct pricing formula.
Google determines whether an ad can appear and where it may show through the ad auction. Auction-time signals and ad quality can influence Ad Rank and the amount you ultimately pay for a click. The Quality Score shown inside Google Ads, however, is primarily a diagnostic tool rather than the direct input advertisers should optimize simply to reduce CPC.
This means improving the underlying experience—stronger intent alignment, more relevant ads and useful landing pages—can contribute to better campaign efficiency. But increasing Quality Score from, for example, 6/10 to 8/10 does not mean your CPC will automatically fall by a predictable percentage.
How to Improve Google Ads Quality Score
Improving Quality Score starts with improving the experience behind its three components—not trying to manipulate the score itself. Focus on creating a stronger connection between what someone searches, the ad they see and the landing page they reach.
If one of your component ratings is Below Average, use it as a starting point for diagnosis. The following areas are usually the most useful places to investigate.
How to Check Quality Score in Google Ads
Google Ads lets you view Quality Score at the keyword level together with the three component ratings that help explain the score: Expected CTR, Ad Relevance and Landing Page Experience.
These columns are not always visible by default, so you may need to add them to your keyword reporting view before you can use them for diagnosis.
Common Google Ads Quality Score Problems and What to Check
A low Quality Score does not tell you exactly what is wrong. The more useful approach is to examine the individual component ratings and connect them with what is happening across your keywords, ads and landing pages.
Use the following troubleshooting framework as a starting point. It helps narrow the investigation before you start changing bids, rewriting ads or rebuilding landing pages unnecessarily.
Google Ads Quality Score Optimization Checklist
Use this checklist when reviewing keywords with weak Quality Score components. You do not need to change everything at once. Start with the component showing the clearest weakness, make focused improvements and measure whether those changes improve actual campaign performance.
Frequently Asked Questions About Google Ads Quality Score
Still have questions about how Google Ads Quality Score works? Here are concise answers to some of the most common questions advertisers have about Quality Score, its components and how to use it when optimizing campaigns.
What Is a Good Quality Score in Google Ads?
A Quality Score of 7 or higher is generally considered strong, but there is no universal score that every keyword needs to achieve. Quality Score is relative and should be used as a diagnostic indicator rather than a target.
Instead of focusing only on the 1–10 number, review Expected CTR, Ad Relevance and Landing Page Experience to identify where improvements may be needed. Most importantly, evaluate keywords based on conversions, CPA, ROAS, lead quality and business value.
Is 7/10 a Good Google Ads Quality Score?
A 7/10 Quality Score is generally a healthy result, particularly when the keyword is also generating valuable conversions at an acceptable cost.
There is usually little reason to chase a 10/10 score simply for the sake of achieving a higher number. If a 7/10 keyword is producing profitable results, other areas of the account may deserve optimization attention first.
Does Quality Score Affect CPC?
Quality and relevance can influence Google Ads auction performance and the price you pay for clicks, but the visible 1–10 Quality Score should not be treated as a direct CPC formula.
Your actual CPC is determined through the ad auction and can be influenced by factors including competition, bids, auction-time ad quality and context. Improving the underlying relevance and experience can contribute to better efficiency, but moving from a Quality Score of 5 to 8 does not guarantee a specific reduction in CPC.
Does Quality Score Affect Ad Rank?
The visible 1–10 Quality Score itself is a diagnostic metric and is not used directly as an auction-time input for Ad Rank.
Google evaluates auction-time signals when determining whether an ad is eligible to show and where it may appear. Quality Score can still be useful because its component ratings help diagnose areas related to the quality and relevance of the search experience.
Can a Keyword With a Low Quality Score Still Convert?
Yes. A keyword with a low Quality Score can still generate conversions and may even be commercially valuable.
That is why you should not automatically pause a keyword simply because its Quality Score is low. Review the component ratings to understand the potential problem, then compare the keyword with its conversion rate, CPA, revenue, ROAS, lead quality and overall business value.
How Often Does Google Ads Quality Score Update?
Quality Score can change as Google gathers new information about the performance and relevance of a keyword, its ads and the associated landing-page experience.
Rather than checking the score constantly, use it periodically as a diagnostic signal. After making meaningful changes, allow enough data to accumulate and evaluate both the component ratings and actual campaign performance.
Why Is My Google Ads Quality Score Low?
A low Quality Score can be associated with weakness in one or more of its three components:
- Expected CTR
- Ad Relevance
- Landing Page Experience
For example, your ad may not be compelling enough, the messaging may not closely match search intent, or the landing page may provide a weak post-click experience.
Check which component is rated Below Average before deciding what to change.
Should I Pause Keywords With a Low Quality Score?
A low Quality Score is a reason to investigate the keyword, not necessarily pause it. First determine which component is weak and whether the keyword is generating valuable business results.
A strategically important keyword with a lower Quality Score may still deserve investment if it produces profitable conversions. Conversely, a keyword with a high Quality Score is not necessarily valuable if it generates poor-quality traffic or fails to convert.
