What Is Google Ads Quality Score?

Google Ads Quality Score is a keyword-level diagnostic score from 1 to 10. It summarizes how relevant and useful an ad and its landing page appear for a keyword compared with other advertisers for the same search. The score uses three component assessments: expected clickthrough rate, ad relevance, and landing page experience.

The important qualification is that Quality Score is not a business-performance KPI and is not an input in the ad auction. Google describes it as a diagnostic tool. Use it to find a possible message, keyword-theme, or landing-page problem, then check actual CTR, conversions, qualified outcomes, cost, and value before deciding what to change. Google’s official Quality Score explanation is the reference for the metric; how to use Quality Score provides a deeper workflow.

What does the Quality Score number mean?

The 1–10 number is a comparative diagnostic. A higher number generally means Google’s historical evaluation found the ad and landing page more relevant and useful for the keyword than the alternatives shown for the same search. It does not mean the keyword is profitable, the ad will win, or the customer experience is perfect.

Think of the number as a warning light, not a destination. A low score can reveal a mismatch worth investigating. A high score can coexist with an unattractive offer, weak sales quality, incorrect tracking, or a campaign that targets the wrong audience. The business outcome must remain the main decision criterion.

Quality Score is reported at the keyword level. It is not a single health score for an account, campaign, website, or agency. Avoid adding the values together or averaging them and presenting the result as though Google defines an account-wide Quality Score.

What are the three Quality Score components?

Google evaluates three components, each with a status such as Above average, Average, or Below average:

The component statuses are usually more useful than the headline number. They point toward different checks and prevent a team from making the same generic change to every low-scoring keyword.

Expected clickthrough rate

Expected clickthrough rate is a prediction about the likelihood of a click when the ad appears for the keyword. It is not the same as the account’s actual CTR, and a high CTR is not automatically good if it brings unqualified traffic or creates a promise gap.

If this component is below average, inspect the query, offer, ad wording, competitive context, and the page that follows the click. Ask whether the intended customer can quickly understand why the ad is relevant. Compare the diagnostic status with actual CTR and qualified conversion data before rewriting the ad solely to increase clicks.

Ad relevance

Ad relevance evaluates the relationship between the ad and the user’s search intent. A below-average status can indicate that an ad group combines different themes or that the ad speaks too generally to the keyword.

A useful response may be to separate distinct intents, tighten the keyword theme, and write a specific ad that accurately describes the offer. Inserting the keyword mechanically into copy is not the same as making the message relevant. The ad should answer the customer’s question and set an expectation the landing page can meet.

Landing page experience

Landing page experience concerns what happens after the click. The page should be relevant to the search and ad, useful to the visitor, easy to navigate, and consistent with the promise made before the click. Google’s landing-page glossary entry describes these types of experience as related to Quality Score.

When this component is below average, compare the exact query, ad, page heading, offer, proof, qualification, form or next action, navigation, mobile layout, and destination behavior. A fast page that answers a different question is still a poor match. A relevant page cannot repair an ad that sends the wrong expectation.

How is Quality Score determined?

Google says the three components are evaluated by comparing performance with other advertisers whose ads showed for the exact same search over the previous 90 days. That makes Quality Score a historical, comparative diagnostic rather than a live page audit.

The score can therefore reflect more than the text currently visible in the account. Competitive conditions, historical impressions, recent changes, and the data available for the keyword all matter. A recent ad or landing-page edit may not appear as an immediate change in the number.

Google also explains that a broad match keyword can have a Quality Score without its own impressions when a corresponding exact match keyword in the same ad group has recent exact-match impressions. If the report seems inconsistent with a keyword’s visible traffic, read the current Google Ads Quality Score documentation rather than assuming the score is a simple current CTR calculation.

What does a dash mean?

When the Quality Score column shows a dash, Google says there are not enough searches that exactly match the keyword to determine a score. A dash is missing diagnostic data, not a score of zero and not proof that the ad or page is poor.

Use other evidence while the data is insufficient: inspect the keyword theme, actual search terms if available, ad and page alignment, policy status, impressions, clicks, and conversions. Do not create a forced optimization target from an unavailable metric.

Is Quality Score used in the ad auction?

No. Google states that Quality Score is not an input in the ad auction. It is a diagnostic tool intended to show how the ad and page compare for the keyword. The live auction has its own real-time ad-quality and context assessments, alongside bid and other factors.

This distinction matters because a score improvement is not a guaranteed position, cost, or conversion improvement. It can still be useful to fix an Average or Below average component when that component points to a genuine mismatch. The goal is a better experience and better business result; the number is evidence that may help prioritize the work.

Quality Score is also not Optimization score. Optimization score provides a broader view of account and campaign recommendations. Quality Score is a keyword-level diagnostic. Neither metric replaces the campaign’s conversion, revenue, margin, qualified-pipeline, or other agreed objective.

How do you check Quality Score?

Google Ads exposes the current score and component statuses in the keyword table. The interface can change, but Google’s current path is broadly:

1. Go to the Keywords view inside the campaign area.
2. Open the columns control in the performance table.
3. Expand the Quality Score fields.
4. Add Quality Score, Landing Page Exp., Exp. CTR, and Ad Relevance.
5. Add historical versions when you need to compare daily or period changes.
6. Apply the columns and inspect the keywords that matter to the business.

Do not make a decision from the headline number alone. Record the keyword, match type, ad group, campaign, landing page, component statuses, actual CTR, conversion quality, cost, value, and recent changes. A high-volume commercial keyword and a low-volume experimental keyword should not receive the same priority merely because their numbers differ.

How should a low Quality Score be interpreted?

Interpret it as a prompt to investigate one of three relationships:

Then check business evidence. A low score on a valuable niche term may be less urgent than a moderate score on a high-spend theme with poor qualified outcomes. A high score on a branded keyword may require less work than a lower score on a strategic non-brand term that is producing the right customers.

If expected CTR is below average

Review whether the ad’s value proposition is clear for the search and whether the wording creates the right expectation. Compare actual CTR, query intent, competitive context, and downstream quality. Do not increase clicks by making a promise the page cannot keep.

If ad relevance is below average

Check whether the ad group combines unrelated keywords or whether the ad speaks vaguely to a specific need. Separate distinct themes where appropriate and write an accurate message for the search. Keyword insertion alone is not a relevance strategy.

If landing page experience is below average

Compare the search, ad, page heading, offer, qualification, proof, navigation, mobile layout, and action. Make the page useful for the intent that the ad actually attracts. A cosmetic speed or copy change cannot fix a page that answers another question.

What Quality Score does not tell you

Quality Score does not tell you whether:

• the keyword is profitable;
• the conversion action is qualified or counted correctly;
• the landing page has the right offer or price;
• the traffic fits the business’s geography or audience;
• the campaign should receive more budget;
• the ad will win a particular auction;
• the account has good overall performance;
• a change caused a revenue or pipeline improvement.

Use conversions, qualified stages, revenue, margin, customer quality, cost, and the campaign’s agreed objective for those decisions. Use the score to decide where a relevance investigation may be worthwhile.

Common misconceptions

“A 10/10 keyword is automatically successful”

It is not. A high diagnostic score can accompany an unprofitable offer, poor sales quality, wrong targeting, or faulty tracking. Keep the business outcome above the score.

“A low score means the keyword must be paused”

Not necessarily. A low score may identify a fixable page or message mismatch, and a valuable niche term may justify the work. Check spend, intent, qualified outcomes, and the component status before pausing.

“Quality Score is the same as Ad Rank”

It is not. Quality Score is the displayed diagnostic. Ad Rank and live auction quality use real-time assessments and other inputs. Do not promise a direct position or cost change from a score movement.

“Adding the keyword to the ad always improves relevance”

Mechanical keyword insertion can make copy repetitive or misleading. Relevance comes from a clear relationship between the search, the ad, the offer, and the page.

“Changing match type resets the score”

Google describes Quality Score as based on historical impressions for exact searches of the keyword. A match-type edit by itself is not a reliable improvement strategy. Review the actual theme and user experience instead.

“The account needs one average Quality Score”

Quality Score is a keyword-level diagnostic. An account-wide average hides the volume and business importance of individual themes and is not the metric Google defines.

A simple Quality Score review checklist

Before changing a keyword or page, record:

1. keyword, match type, ad group, campaign, and landing page;
2. current score and the three component statuses;
3. actual search terms and the intent they represent;
4. actual CTR, conversions, qualified outcome, cost, and value;
5. the promise made by the ad and the experience delivered by the page;
6. recent changes to bids, budget, targeting, conversion actions, ads, and page;
7. the suspected cause of the component issue;
8. the business metric that will determine whether the change worked.

Make the smallest change that addresses the suspected cause. Afterward, record the diagnostic change and the business result separately. An improved component is evidence about relevance; it is not proof that revenue or profitability improved because of that change.

The short answer

Google Ads Quality Score is a 1–10, keyword-level diagnostic built from expected CTR, ad relevance, and landing page experience. It compares historical relevance with other advertisers for the same search. It helps prioritize investigation, but it is not an auction input, account KPI, profit measure, or replacement for conversion data.
