• C. QS has no effect on CPC.
• D. QS determines ad spend limits.

Answer: (B)

Quality Score directly affects the amount you end up paying per click in an auction by reducing the CPC needed to win the same position. In Google Ads, Ad Rank is influenced by your bid and your Quality Score, and the actual CPC you pay is the minimum required to keep your Ad Rank above the next advertiser’s. A common way to think about it is: Actual CPC ≈ (Ad Rank of the ad below you) ÷ Your Quality Score, plus a small amount. So, when your Quality Score increases, the numerator stays the same while the denominator grows, meaning you can achieve the same Ad Rank with a lower CPC. For example, if the ad below has an Ad Rank of 12 and your Quality Score is 6, you’d pay about 2.00 per click (plus a cent). If your Quality Score rises to 8, you’d pay about 1.50 per click (plus a cent). This shows that higher Quality Score lowers the actual CPC for the same position; the idea that it would raise CPC doesn’t match how the auction works.
