Use Quality Score as a warning light. Fix weak customer experiences, but judge the campaign by customers and revenue.
Google Ads Quality Score is a 1-to-10 diagnostic score shown at the keyword level. It helps identify whether an ad and landing page appear useful and relevant compared with other advertisers.
It is not revenue. It is not a campaign grade. Google says the Quality Score number itself is not used in the ad auction and should not be treated as a key performance indicator.
Use it like a warning light: it can point toward a problem, but it does not tell you whether the campaign is profitable.
The Simple Answer
Quality Score summarizes three areas:
- Expected clickthrough rate
- Ad relevance
- Landing page experience
Each component can appear as:
- Below average
- Average
- Above average
If a valuable keyword has a weak component, investigate that part of the customer experience. Do not chase a score while ignoring calls, customers and revenue.
The Three Parts of Quality Score
| Component | What it asks | Practical improvement |
|---|---|---|
| Expected clickthrough rate | Are people likely to click this ad when it appears? | Make the offer and message more useful for the search |
| Ad relevance | Does the ad match what the person is looking for? | Group searches tightly and write a direct ad |
| Landing page experience | Is the page useful after the click? | Match the page to the search, make it fast and make the next step clear |
These components are diagnostic. The actual auction considers real-time quality and context, not simply the displayed 1-to-10 number.
What Expected Clickthrough Rate Means
Expected clickthrough rate estimates how likely the ad is to receive a click when shown for the keyword.
A below-average rating may suggest:
- The ad does not answer the search clearly
- The offer is weaker than competing ads
- The headline is generic
- The keyword is too broad for the ad group
- The ad appears for mixed customer needs
Do not improve clickthrough rate with empty promises. A sensational ad may win clicks while producing weak leads.
The goal is a relevant click from a person who could become a customer.
What Ad Relevance Means
Ad relevance measures how closely the ad matches the intent behind the search.
Suppose one ad group contains:
- garage door repair
- garage door installation
- garage door remote
- commercial loading dock door
One generic ad will struggle to speak directly to all four needs.
A cleaner structure might separate:
- Repair searches
- Installation searches
- Opener and remote searches
- Commercial door searches
Each group can then use a more specific ad and landing page.
Review Google Ads match types and actual search terms before rebuilding the account.
What Landing Page Experience Means
Landing page experience considers whether the page is relevant and useful to the person who clicked.
A strong page usually:
- Matches the service or product in the ad
- Loads quickly on a phone
- Explains the offer without unnecessary words
- Makes the phone number or form easy to find
- Provides proof such as reviews, results or credentials
- Works safely and clearly
Sending every click to the homepage often creates friction. The person searched for one thing and should land on a page that addresses it.
How to Check Quality Score
In Google Ads:
- Open Campaigns.
- Go to Keywords.
- Select the columns icon.
- Open the Quality score section.
- Add Quality Score and the three component columns.
- Add historical component columns if you want to compare changes over time.
A dash instead of a score may mean there are not enough eligible searches to calculate it.
What Is a Good Quality Score?
Many advertisers treat 7 or higher as “good,” but that shortcut can create bad decisions.
A keyword with a score of 10 can still lose money. A keyword with a lower score can still produce valuable customers.
Use this order of importance:
- Qualified customers and revenue
- Cost to acquire those customers
- Lead quality and conversion rate
- Quality Score as a diagnostic clue
The score is most useful when a valuable, high-volume keyword shows a specific below-average component.
How to Improve a Low Quality Score
Step 1: Start With Valuable Keywords
Do not spend hours improving a keyword that rarely runs or never produces business. Focus on searches that matter.
Step 2: Check the Search Terms
The keyword may be matching searches with different intent. Remove waste, adjust match types or separate important needs.
Step 3: Tighten the Ad Group
Keep keywords together when the same ad and landing page can answer them well.
Step 4: Rewrite the Ad
State the service, location or useful difference clearly. Match the customer's need without mechanically repeating the keyword.
Step 5: Improve the Landing Page
Make the page faster, clearer and more specific. Ensure the next action—call, form, booking or purchase—is obvious.
Step 6: Check the Business Result
After changes, compare qualified leads, customers and revenue. A higher score is not a win if sales decline.

Quality Score Myths
Myth 1: Quality Score Directly Determines Ad Rank
Google says the displayed Quality Score is not an input in the auction. It is a diagnostic summary. Real-time ad quality still matters, but the score itself is not the auction calculation.
Myth 2: A Score of 10 Guarantees Cheap Clicks
Click prices also depend on competition, bids, context and the value of the search. A strong score does not remove market demand.
Myth 3: Repeating the Keyword Fixes Everything
Useful ads and pages matter more than forced repetition. Answer the intent behind the search.
Myth 4: Every Low Score Must Be Fixed
Prioritize keywords that spend meaningful money or produce valuable customers. Some low-volume keywords do not justify extensive work.
Myth 5: Quality Score Is More Important Than Conversion Tracking
Quality Score cannot tell you which lead became a customer. Conversion tracking connects the ad with the result the business needs.
When Quality Score Is Not the Main Problem
A campaign can have respectable scores and still fail because:
- It targets the wrong locations
- Search terms attract the wrong people
- Calls are not answered
- Forms are broken
- Prices or offers are uncompetitive
- Conversion tracking counts weak actions
- The business cannot profitably support the click cost

Talk to Darlington →Google Ads Quality Score FAQ
What is Google Ads Quality Score?
It is a 1-to-10 keyword-level diagnostic based on expected clickthrough rate, ad relevance and landing page experience.
Does Quality Score affect cost per click?
The displayed score itself is not used in the auction. The underlying quality of the ad and landing-page experience can affect performance, but cost also depends on competition, bids and context.
Is a Quality Score of 5 bad?
It suggests room for investigation, not an automatic failure. Check the three components and compare the keyword with real leads and customers.
Why does my keyword show no Quality Score?
Google may not have enough eligible search activity to calculate one.
How quickly can Quality Score change?
The displayed score updates as Google gathers relevant performance information. Make improvements for customers first, then monitor the components over time.
The Bottom Line
Quality Score is a diagnostic tool, not the goal of Google Ads.
Use it to find weak ads, mixed search intent and poor landing pages. Then judge every improvement by the result that matters: better calls, more customers and profitable revenue.
