Quality Score
Google's 1–10 rating of your ad quality, relevance, and landing page experience.
Definition
Quality Score is Google's 1–10 rating of how relevant and useful your ad is to users searching for your keywords. It is calculated from three components: expected clickthrough rate (CTR), ad relevance, and landing page experience. A higher Quality Score means lower CPCs and better ad positions — it directly reduces your cost of advertising.
The Practitioner's Perspective
Quality Score is calculated at the keyword level. Google estimates how likely users are to click your ad for a given keyword (expected CTR), how closely your ad copy matches the search intent (ad relevance), and how well your landing page delivers on what the ad promised (landing page experience). Each component is rated Below Average, Average, or Above Average.
The financial impact of Quality Score is substantial. An account with a Quality Score of 8 might pay $3.00 for a click that an account with a Quality Score of 4 pays $6.00 for — same position, half the cost. Over a monthly budget of $10,000, that's $5,000 saved just from higher quality. This is why investing in landing page optimization and tight keyword-ad alignment is so valuable.
For healthcare advertisers, improving Quality Score often means tighter ad group structure (one theme per group), procedure-specific landing pages instead of general homepage sends, fast mobile load times, and clear calls to action. Healthcare-specific terms that seem obvious in your practice may be treated as low relevance by Google if your landing page doesn't explicitly use that language.
Frequently Asked Questions
What Quality Score should I aim for?
Aim for 7+ on your main keywords. Scores of 7–10 mean you're getting discounts on your CPC. Scores below 5 typically mean you're overpaying and should restructure your ad groups or landing pages.
Does Quality Score affect all campaign types?
Quality Score is most relevant for Search campaigns. Performance Max and Display campaigns use different quality signals. Smart Bidding strategies incorporate quality signals automatically, so Quality Score is especially important when bidding manually or with target CPC.
Why does my Quality Score drop when I pause ads?
Quality Score includes historical account performance. When you pause campaigns for extended periods, Google loses fresh data on CTR and conversions. Gradual optimization beats frequent pausing and restarting.
