Summary  
This chapter covers how to compute and use a composite scoring algorithm—combining predicted click-through rate, content relevance, and user experience metrics—to influence ranking and cost.  

General domain of usage  
Online advertising auctions (digital ad campaigns)

Your **Quality Score** is Google's behind-the-scenes rating of your ads, keywords, and landing pages. A higher score lowers your CPC, improves ad rank, and helps you win auctions. 


**Google's Quality Score** is a rating (from **1 to 10**) that decides how much you pay and where your ad appears. That measures:
- How relevant your ad is to what people are searching for;
- How engaging your ad copy is;
- How useful your landing page feels once someone clicks.

The higher your score, the lower your **cost per click (CPC)** and the better your **ad rank**.

Definition

### Factors That Affect Quality Score
1. **Expected Click-Through Rate (CTR)**: Google predicts how likely people are to click your ad.
It looks at past performance and how closely your ad copy matches what users search for;
2. **Ad Relevance**: does your ad clearly answer the user's search intent?
3. **Landing Page Experience**: load fast, be mobile-friendly, match your ad's promise, and be clear and transparent about what you're offering.
