This guide covers what Quality Score actually measures, which components matter most, and practical steps to improve it across your account.
What Quality Score Actually Is
Quality Score is Google's 1-10 rating of how relevant your keyword, ad, and landing page combination is to someone's search. It's calculated at the keyword level and updated regularly based on real performance data.
Here's the thing most people miss: Quality Score directly affects what you pay per click. A keyword with a Quality Score of 8 will pay less per click than the same keyword with a Quality Score of 4, even if both are in the same auction with the same bid. Google rewards relevance with lower costs.
The actual formula works through something called Ad Rank. Your Ad Rank = your bid x your Quality Score (simplified). So if you bid $5 with a Quality Score of 8, your Ad Rank is 40. Your competitor bids $7 with a Quality Score of 5, their Ad Rank is 35. You win the auction and pay less.
The Three Components
Quality Score has three components, and they're not weighted equally:
- Expected Click-Through Rate (CTR): How likely someone is to click your ad. This is the most heavily weighted factor. Google compares your actual CTR against expected CTR for your position and ad format.
- Ad Relevance: How closely your ad copy matches the search intent. If someone searches "blue running shoes" and your ad headline says "Athletic Footwear Store," that's a weaker match than "Blue Running Shoes on Sale."
- Landing Page Experience: How useful and relevant your landing page is after someone clicks. Speed matters here, but so does content relevance and navigation ease.
Each component gets a rating of "Below Average," "Average," or "Above Average." You can see these in the Google Ads interface by adding the Quality Score columns to your keyword view.
How to Improve Expected CTR
Expected CTR is the biggest lever. Here's what actually moves it:
- Include the keyword in your headline. This sounds obvious, but it's the single most effective thing you can do. If the keyword is "google ads audit," your headline should contain those words.
- Write specific ads, not generic ones. "Get a Google Ads Audit Today" outperforms "Digital Marketing Services" for that keyword every time.
- Use all available ad space. RSAs with 10+ headlines and 4 descriptions get more real estate, which means more clicks. More clicks = higher CTR = better Quality Score.
- Add extensions. Sitelinks, callouts, and structured snippets increase your ad size, which increases CTR even if the extensions themselves don't get clicked.
How to Improve Ad Relevance
Ad relevance is about the match between keyword intent and ad copy. The simplest improvement: organize your ad groups so each one contains tightly related keywords with ads specifically written for those keywords.
The classic mistake is having one ad group with 50 keywords and one set of generic ads. Split that into 5 ad groups with 10 keywords each, and write specific ads for each group. Your ad relevance will improve almost immediately.
Also check that your keyword match types make sense. Broad match keywords can trigger for searches that are only loosely related to your ad. If your ad says "Google Ads Audit" but broad match is triggering it for "Facebook advertising tips," the relevance score will suffer.
How to Improve Landing Page Experience
Landing page experience is partly about speed and partly about content relevance.
Speed: Your landing page should score at least 50 on Google PageSpeed Insights for mobile. Below 50 and you're probably getting dinged. The biggest speed killers are uncompressed images, too many scripts, and slow server response times.
Content relevance: If someone clicks an ad for "google ads audit" and lands on your homepage, that's a weaker match than landing on a page specifically about Google Ads audits. Create dedicated landing pages for your highest-spend keywords.
User experience: Google also considers navigation clarity, trust signals, and whether the page delivers on what the ad promised. A page with a clear call to action, relevant content above the fold, and easy navigation scores better than a cluttered page.
What Quality Score Numbers Actually Mean
Here's a rough guide to interpreting Quality Scores:
- 7-10: Good. You're paying fair or below-market rates. Keep doing what you're doing.
- 5-6: Average. There's room to improve, and improving will lower your CPCs. Focus on the component rated "Below Average."
- 1-4: Below average. You're paying a premium for every click. These keywords either need significant work or should be paused if they're not converting.
One thing worth noting: Quality Score for branded keywords is usually 8-10 because you're inherently the most relevant result. Don't worry about those. Focus your improvement efforts on non-branded keywords where Quality Score is 6 or below.
Common Quality Score Myths
A few things that people think affect Quality Score but probably don't (or at least not directly):
- Account history: There's some evidence that overall account performance affects new keywords, but it's a minor factor compared to the three main components.
- Bid amount: How much you bid doesn't affect Quality Score. It affects Ad Rank, but Quality Score is calculated independently of your bid.
- Pausing and restarting keywords: Pausing a keyword doesn't reset its Quality Score. When you reactivate it, it picks up roughly where it left off.

Frequently Asked Questions
Performance Max doesn't show a Quality Score metric, but the underlying relevance factors still apply. Google's algorithm considers ad relevance, landing page quality, and expected engagement when deciding where and how often to show your PMax ads.
Changes to ad copy and extensions can affect Quality Score within 1-2 weeks as Google collects new performance data. Landing page improvements may take longer because Google recrawls pages on its own schedule. Most advertisers see noticeable changes within 2-4 weeks of making improvements.
For most keywords, 7 is solid. You're not paying a penalty at that level. Pushing from 7 to 9 gives diminishing returns. Focus improvement efforts on keywords scored 5 or below, where the cost penalty is highest.
