Understanding Quality Score Components

Which of the following is NOT a direct factor that influences the Quality Score of an online advertisement?

A The advertiser's total monthly budget

B Ad relevance to the search query

C Expected click-through rate (CTR)

D Landing page experience

💡 Hint

Ad Rank Calculation

What is the formula used to calculate Ad Rank in most online advertising platforms?

A Ad Rank = Quality Score ÷ Maximum Cost-Per-Click (CPC) Bid

B Ad Rank = Quality Score + Maximum Cost-Per-Click (CPC) Bid

C Ad Rank = Maximum Cost-Per-Click (CPC) Bid - Quality Score

D Ad Rank = Quality Score × Maximum Cost-Per-Click (CPC) Bid

💡 Hint

Ad Rank combines how good your ad is and how much you are willing to pay.

Ad Rank is calculated by multiplying Quality Score by the maximum CPC bid. This determines the position of the ad.

Effect of Low Quality Score on Advertising Strategy

An advertiser notices their ads have a low Quality Score. Which of the following strategies is least effective to improve their ad performance?

A Enhancing the landing page experience for users

B Improving the relevance of ad text to keywords

C Increasing the maximum CPC bid without changing the ad content
