Quality Score might be the most misunderstood metric in Google Ads. Some advertisers obsess over it. Others ignore it completely. The truth is somewhere in between—and understanding it can save you thousands in ad spend.
In this guide, I’ll explain exactly what Quality Score is, why it matters (and when it doesn’t), and give you a practical framework for improving it. No fluff, just the stuff that actually moves the needle.
What Is Quality Score?
Quality Score is a 1-10 rating that Google assigns to each keyword in your account. It’s based on Google’s estimate of how relevant and useful your ads and landing pages are to someone searching for that keyword.
Important clarification: Quality Score is a diagnostic tool, not a direct factor in the ad auction. Google uses real-time calculations of the same components to determine your actual ad rank. Think of Quality Score as a report card showing how you’re doing—not the grade itself.
Why Quality Score Matters
While Quality Score isn’t directly used in auctions, the factors it measures absolutely are. Here’s why you should care:
Lower Costs: Ads with higher quality typically pay less per click. Google rewards relevant ads with better pricing because they create better user experiences.
Better Positioning: Your Ad Rank (which determines where you show up) is calculated as: Maximum Bid × Quality Factors. Better quality means you can win higher positions without paying more.
More Impressions: Low-quality ads may not show at all for certain searches. High quality unlocks more inventory.
The Three Pillars of Quality Score
Quality Score is calculated from three components, each rated as “Above Average,” “Average,” or “Below Average”:
📊
Expected CTR
How likely is someone to click your ad when it shows?
🎯
Ad Relevance
How closely does your ad match the search intent?
📱
Landing Page Experience
Is your landing page useful and relevant?
Understanding Your Score
8-10
Great Quality
You’re doing well. Focus on scaling, not fixing. These keywords are your winners—find more like them.
5-7
Room for Improvement
Decent but not optimal. Check which component is “Average” or “Below Average” and address that specifically.
1-4
Needs Attention
Something is significantly off. Either the keyword doesn’t fit your offer, your ad copy is misaligned, or your landing page needs work.
How to Improve Each Component
1. Improving Expected Click-Through Rate
Expected CTR measures how likely people are to click your ad. Here’s how to boost it:
- Include keywords in headlines. When someone searches “running shoes,” they should see “Running Shoes” in your headline.
- Add specific numbers. “Save 40%” or “500+ 5-Star Reviews” performs better than vague claims.
- Use compelling CTAs. “Get Free Quote,” “Shop Now,” “See Pricing” tell people what to expect.
- Highlight unique value. Free shipping? Same-day delivery? Money-back guarantee? Say it.
- Test multiple RSA variations. Give Google 8-10 headline options and 3-4 descriptions to find winning combinations.
2. Improving Ad Relevance
Ad relevance measures how well your ad matches search intent. The fix is usually structural:
- Tighten your ad groups. If you have 50 keywords in one ad group, you can’t write ads that speak to all of them. Create smaller, themed ad groups.
- Match ad copy to keywords. The keywords in your ad group should appear naturally in your ads.
- Don’t force irrelevant keywords. If a keyword doesn’t fit your offer, no amount of ad tweaking will fix relevance. Remove it.
Ad Group Rule of Thumb
If you can’t write a single ad that speaks directly to all keywords in the group, the group is too broad. Split it up.
3. Improving Landing Page Experience
This is where many advertisers lose points. Google evaluates whether your landing page delivers what the ad promised:
- Message match is critical. If your ad says “50% off running shoes,” the landing page headline should say the same thing—not “Welcome to our store.”
- Page speed matters. Run PageSpeed Insights and fix issues. A 1-second delay can drop conversions 20%.
- Mobile experience is essential. Over 60% of searches are mobile. If your page isn’t mobile-friendly, you’re losing points and customers.
- Make it easy to convert. Clear CTAs, simple forms, obvious next steps. Reduce friction.
- Original, useful content. Don’t just have a form—provide information that helps the user.
The 80/20 of Quality Score Improvement
Don’t try to fix everything at once. Here’s where to focus for maximum impact:
Step 1: Sort keywords by impressions. High-impression keywords with low Quality Scores are your biggest opportunities.
Step 2: Look at component scores. Is it CTR, relevance, or landing page? Fix the weakest link first.
Step 3: If landing page experience is “Below Average” across many keywords, that’s your priority. One landing page improvement fixes multiple keywords.
Step 4: If ad relevance is low, restructure your ad groups. This is structural work but pays dividends.
Step 5: If expected CTR is low, test new ad copy. This is the fastest to iterate on.
Quality Score Myths
Myth: “I need a 10/10 on every keyword.”
Reality: A 7-8 is perfectly fine for most keywords. Chasing perfect scores often isn’t worth the effort.
Myth: “Quality Score directly determines my CPC.”
Reality: It’s a diagnostic, not a direct input. The same factors influence both, but improving the score doesn’t automatically lower costs.
Myth: “Historical Quality Score affects new keywords.”
Reality: Each keyword gets its own score based on its own performance. Account history matters for new accounts, but individual keywords are evaluated individually.

The Bottom Line
Quality Score is a useful diagnostic tool, not an end goal. Use it to identify weak spots in your campaigns, then focus on fixing the underlying issues: ad relevance, landing page experience, and click-through rate.
The best Quality Score strategy is also the best advertising strategy: create relevant ads that lead to useful landing pages for the people searching your keywords. Do that consistently, and the scores (and results) will follow.
