What is Quality Score?

Quality Score is Google Ads' 1-10 rating of how relevant and useful your ad and landing page are to someone searching for your keyword. Higher scores mean lower costs and better ad positions.

It's Google's way of rewarding advertisers who create good experiences. If your ad answers what the searcher is looking for, Google charges you less per click. If your ad is irrelevant, you pay a premium.

The Three Components

Quality Score is built from three factors, each rated "Below Average," "Average," or "Above Average":

1. Expected CTR: how likely is someone to click your ad for this keyword? Based on your historical click-through rate compared to other advertisers on the same keyword.

2. Ad relevance: how closely does your ad text match the intent behind the keyword? If someone searches "project management tool" and your ad talks about "CRM software," relevance is low.

3. Landing page experience: does your landing page deliver what the ad promised? Google looks at page speed, mobile-friendliness, content relevance, and navigation clarity.

How Quality Score Affects Your Costs

Quality Score directly determines your actual CPC through a formula called Ad Rank:

Ad Rank = Bid x Quality Score

Two advertisers bidding on the same keyword:

• Advertiser A: bids $2, Quality Score 8 = Ad Rank 16
• Advertiser B: bids $3, Quality Score 4 = Ad Rank 12

Advertiser A wins the top position AND pays less per click. Quality Score acts as a multiplier that makes every dollar more effective.

The cost impact is real:

• Quality Score 10: ~50% discount on average CPC
• Quality Score 7: roughly average CPC
• Quality Score 4: ~25% premium on CPC
• Quality Score 1: ~400% premium on CPC

How to Improve Quality Score

• Write specific, benefit-driven headlines
• Include your target keyword in the headline

• Match ad copy language to search intent
• Use responsive search ads with diverse headlines

For Landing Page:
