Google Ads Quality Score
📖 3 min readUpdated 2026-04-19
Quality Score (1-10) is Google's assessment of your ad's relevance to the query and landing page. Higher Quality Score = lower CPC for the same position. It compounds: 30% cheaper CPC on a $10K/month budget = $3K/month in savings.
The three components
- Expected CTR: will people click this ad?
- Ad Relevance: does the ad match the keyword?
- Landing Page Experience: does the page match what was promised?
Each scored average, above average, below average. Combined into Quality Score.
How to improve Expected CTR
- Keyword in headline
- Specific, concrete benefit
- Numbers, prices, specific details
- Strong CTA
- Ad extensions (sitelinks, callouts, structured snippets)
How to improve Ad Relevance
- Tight ad groups (10-20 tightly-related keywords per ad group)
- Keyword in headline and/or description
- One ad group per specific intent, not "everything" ad groups
How to improve Landing Page
- Landing page matches the ad promise
- Fast load time (under 3 seconds)
- Mobile-friendly
- Clear CTA matching the ad's action
- Relevant content (not your homepage)
The compounding effect
Quality Score 7 → Quality Score 9 can cut CPC 40%+. Combined with better CTR from relevance, your effective cost per conversion can halve.
Common Quality Score killers
- Sending all traffic to homepage
- Running 50 keywords in one ad group with generic ad copy
- Landing page has nothing to do with the search query
- Slow mobile load time
- No ad extensions
What to do with this
- Create a dedicated landing page per ad group, sending everyone to your homepage is the single biggest quality score leak
- Include the main keyword in the page headline, URL, and first paragraph, Google rewards match between query and page
- Fix mobile load time first, it affects both quality score and real conversion, below 2 seconds is the target
- Group keywords tightly by theme (3-20 per ad group, not 50), tight groups let ad copy speak to the specific query intent
- Use all available ad extensions (sitelinks, callouts, structured snippets), they lift quality score and CTR without added cost
