What is Google Ads Quality Score?

Quality Score is Google's rating of the relevance and quality of your keywords, ads, and landing pages. It's reported on a 1–10 scale and directly impacts your ad rank and cost per click (CPC).

Key Components of Quality Score

• Expected Click-Through Rate (CTR): How likely your ad is to be clicked when shown.
• Ad Relevance: How closely your ad matches the intent behind a user’s search.
• Landing Page Experience: How relevant and useful your landing page is to people who click your ad.

How to Improve Your Quality Score

• Group keywords by theme: Create tightly themed ad groups for higher relevance.
• Write compelling, relevant ads: Match ad copy to keywords and user intent.
• Optimize landing pages: Ensure fast load times, mobile-friendliness, and clear calls to action.
• Use all available ad extensions: Sitelinks, callouts, and structured snippets can boost CTR and relevance.
• Monitor and test regularly: Track Quality Score changes and test new ideas to keep improving.

Advanced Techniques for 2026

• Leverage AI for ad copy and landing page optimization: Use machine learning tools to personalize and test at scale.
