Quality Score is Google's internal rating — displayed on a 1 to 10 scale — that measures how well your keyword, ad copy, and landing page work together to serve the user's intent. It directly affects how much you pay per click and where your ad appears. The three components of Quality Score: **Expected Click-Through Rate (CTR)**: How likely your ad is to be clicked when shown for a given keyword, compared to historical data. This is the most heavily weighted component. **Ad Relevance**: How closely your ad copy matches the intent of the keyword being searched. If someone searches 'SEO services Chandigarh' and your ad says 'Digital Marketing Company India,' relevance is poor. **Landing Page Experience**: How useful, relevant, transparent, and easy-to-navigate your landing page is for someone who clicked the ad. A page full of pop-ups, irrelevant content, or slow loading will damage this score. The business impact is significant. An advertiser with Quality Score 8 can pay nearly half the CPC of a competitor with Quality Score 4 while still appearing in the same position. This is Google's mechanism to ensure useful ads win — not just the ones with the biggest budget. Actionable tip: Go to your Google Ads account, add the Quality Score column to your keywords view, and immediately focus attention on any keyword with a score of 5 or below. Rewrite the ad group's ads to tightly match those keywords, and check that the landing page speaks directly to what the ad promises.
