When an ad gets a high number of clicks relative to the number of impressions, what impact could this have on the ad’s Google Ads auction?
Correct Answer
It could help the ad get a higher placement on the Ad Rank.
Why is this the correct answer?
When an ad gets a high number of clicks relative to the number of impressions — a high click-through rate — it could help the ad get a higher placement on Ad Rank. CTR is a key component of expected click-through rate, which is one of the three factors that determine Quality Score. A higher Quality Score raises Ad Rank, allowing the ad to compete for better positions in the auction and potentially achieve higher placements without requiring a higher maximum bid.
Why are the other options incorrect?
It could increase the cost-per-click for the advertiser.
A high CTR does not increase cost-per-click — it typically lowers it, because a higher Quality Score gives the ad a better Ad Rank at the same or lower bid.
It could help the advertiser receive more bids in the auction.
A high CTR does not cause the advertiser to receive more bids — bidding in Google Ads is determined by competing advertisers, not by the performance of a single ad.
It could lower the cost-per-click by 40% or more.
While a high CTR can reduce CPC, the '40% or more' figure is not an accurate or official benchmark — the actual savings depend on the auction dynamics and competitor bids.
Real-World Example
A SaaS company's search ad consistently achieves a 12% CTR against an industry average of 4%. Google's auction system rewards this strong expected click-through rate with a higher Quality Score of 9/10. As a result, the ad appears in position 1 on searches where a competitor with a higher max CPC but weaker CTR sits in position 2 — demonstrating how high CTR drives higher placements through Ad Rank.
