What value is used to determine whether your ad will show on a page and, if so, the ad’s position?
Correct Answer
Ad Rank
Why is this the correct answer?
Ad Rank is the value used to determine whether your ad will show on a page and, if so, the ad's position. Ad Rank is calculated using your CPC bid, Quality Score (which includes expected CTR, ad relevance, and landing page experience), the expected impact of ad extensions, and the context of the search. A higher Ad Rank wins a better position in the auction. Ad Rank is recalculated in every auction, meaning your position can change with each search based on competition and context.
Why are the other options incorrect?
Quality Factor
Quality Factor is not a Google Ads term — it does not exist as a metric in the Google Ads system.
Quality Score
Quality Score is a component of Ad Rank (on a scale of 1-10) but is not the value used directly to determine ad position. Ad Rank uses Quality Score as one input alongside bid and other factors.
Ad Score
Ad Score is not a Google Ads metric — this term does not exist in the Google Ads platform.
Real-World Example
Two advertisers bid on the keyword accountant Bristol. Advertiser A bids £3.00 with a Quality Score of 4, giving an Ad Rank of 12. Advertiser B bids £1.50 with a Quality Score of 9, giving an Ad Rank of 13.5. Advertiser B wins the higher position despite the lower bid — demonstrating that Ad Rank, not bid alone, determines position.
