Quality Score is a diagnostic metric in Google Ads that evaluates the quality and relevance of an advertiser’s search ads compared with other advertisers. It is reported on a scale of 1 to 10 for eligible search keywords and helps advertisers identify opportunities to improve their ads, keyword targeting, and landing pages.
Quality Score is based on three main components: expected click-through rate (CTR), ad relevance, and landing page experience.
The three components of Quality Score
Expected CTR: Estimates how likely an ad is to receive clicks compared with other ads, based on Google’s assessment.
Ad relevance: Measures how closely an advertisement matches the intent behind a user’s search.
Landing page experience: Evaluates how relevant, useful, and user-friendly the page is after someone clicks the ad.
Google reports each component as Below average, Average, or Above average.
Example of Quality Score
Suppose a Shopify jewellery store advertises diamond engagement rings on Google.
A user searches for “diamond engagement rings,” but the ad provides general jewellery information and leads to a broad homepage.
The keyword may receive a lower Quality Score if its expected CTR, ad relevance, or landing page experience is weak. The store could improve these areas by creating more relevant ad copy and directing users to a dedicated engagement-ring collection page.
Why is Quality Score useful?
Identifies weaknesses in search advertising campaigns.
Helps advertisers improve keyword and ad relevance.
Highlights opportunities to improve landing pages.
Supports better-informed campaign optimization.
Provides diagnostic information when reviewing search performance.
Important: Quality Score is a diagnostic metric, not a direct input in every Google Ads auction. A higher score does not guarantee a better ad position or lower cost per click (CPC).
In short: Quality Score is Google’s 1–10 diagnostic rating for eligible search keywords, based on expected CTR, ad relevance, and landing page experience. It helps advertisers identify where their search campaigns can improve.
