Quality Score
Quality Score is a diagnostic metric in Google Ads that rates the relevance and quality of your keywords, ads, and landing pages on a scale of 1 to 10. It directly influences your Ad Rank, which determines both your ad position and your cost per click. A higher Quality Score means better placements at lower costs than competitors with weaker scores.
How Quality Score Is Calculated
Google evaluates three core components, each rated as “above average,” “average,” or “below average.” Expected click-through rate (CTR) estimates how likely users are to click your ad when it appears. Ad relevance measures how closely your ad copy matches the intent behind a user’s search query. Landing page experience assesses whether your landing page provides relevant, useful content with fast load times and easy navigation.
These components are calculated at the keyword level, meaning each keyword in your account has its own Quality Score. Historical performance, particularly CTR compared to other advertisers bidding on the same keyword, is the most heavily weighted factor.
Why Quality Score Matters
Quality Score has a direct financial impact. Google uses it alongside your maximum bid to calculate Ad Rank: Ad Rank = Maximum CPC Bid x Quality Score. An advertiser with a Quality Score of 8 bidding $2 outranks an advertiser with a Quality Score of 4 bidding $3. This system rewards advertisers who create relevant, high-quality ad experiences.
Over the lifetime of a campaign, Quality Score improvements compound significantly. Increasing a keyword’s Quality Score from 5 to 8 can reduce CPC by 30-50%, freeing budget that can be reinvested into additional traffic or new campaigns.

How to Improve Quality Score
Start by tightening the alignment between keywords, ad copy, and landing pages. Group closely related keywords into focused ad groups rather than mixing broad themes. Write ad copy that directly addresses the search intent and includes the target keyword. Ensure landing pages deliver on the ad’s promise with relevant content, clear calls to action, and fast load times.
Use search advertising tools to monitor Quality Score trends across your account and identify underperforming keywords that need optimization or restructuring.
