Google Ads Quality Score

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
