Which of these factors affect whether a Search ad shows in the results for a query and what position it assumes?
Correct Answer
Ad Rank does this, and it’s based on a variety of factors to show useful ads.
Why is this the correct answer?
Ad Rank determines whether a Search ad shows in the results for a query and what position it assumes, and it is based on a variety of factors including bid, ad quality, expected impact of assets, auction competitiveness, and context signals such as device and location. Ad Rank is calculated at every auction, meaning every single search query triggers a fresh calculation. A higher Ad Rank wins better placement — and because quality and relevance are major inputs, advertisers with highly relevant ads can outrank competitors with higher bids but lower quality scores.
Why are the other options incorrect?
Bids does this and it’s determined by how much marketers will pay for a click.
Bids alone do not determine whether an ad shows or its position — bids are one input into Ad Rank, but quality, relevance, and other factors mean a higher bid does not guarantee a better or even equal placement.
Ad quality does this, and it’s based on ad and website relevance.
Ad quality is a component of Ad Rank (via Quality Score), not a standalone factor that independently determines placement — it contributes to the overall Ad Rank calculation alongside bid and other signals.
Asset impact does this, and it’s based on sitelinks and image assets.
Asset impact (sitelinks, image assets) contributes to Ad Rank as the 'expected impact of extensions' component, but it is one input rather than an independent factor that determines placement on its own.
Real-World Example
Two advertisers compete on the query 'best project management software'. Advertiser A bids £3.50 but has a Quality Score of 5/10. Advertiser B bids £2.80 but has a Quality Score of 9/10 and strong sitelinks. Ad Rank places Advertiser B in position 1 and Advertiser A in position 2 — demonstrating that Ad Rank's variety of factors rewards quality over the highest bid alone.
