What is Quality Score? Quality Score is a metric used in Google Ads that measures ad, keyword, and landing page relevance—indicating how well your ads match user intent.

What Is Quality Score in Ads?

Quality Score is a diagnostic tool in Google Ads that helps advertisers evaluate how effectively their campaigns align with what users are searching for. While the score itself is simplified into a 1–10 rating based on historical impressions for exact searches of your keyword, it reflects deeper performance signals tied to user experience and relevance.

It’s calculated using three primary factors:

• Expected click-through rate (CTR): The likelihood that users will click your ad.

• Ad relevance: How closely your ad matches the user’s search query.

• Landing page experience: How useful, relevant, and easy-to-navigate your destination page is.

Why Does Quality Score Matter?

A higher Quality Score can lead to lower cost-per-click (CPC), better ad placements, and improved overall efficiency. While not a direct input in auction-time Ad Rank, it reflects the same signals that influence visibility and cost.

How Can You Improve Quality Score in Ads?

• Align keywords, ads, and landing pages around clear intent.

• Write specific, compelling ad copy to boost CTR.

• Optimize landing pages for speed, clarity, and relevance.

Quality Score isn’t a KPI, but rather it's a valuable diagnostic indicator of campaign health and optimization opportunities.
