Definition of ad rank in advertising

Ad Rank is a value used by search engines like Google to determine the position of an advertisement on a search engine results page (SERP). It is calculated based on a combination of factors, including bid amount, ad quality (quality score), expected click-through rate (CTR), ad relevance, and the landing page experience. Ad Rank ensures that the most relevant and effective ads are shown to users.


Ad Rank plays a critical role in search engine marketing (SEM) by influencing the visibility and cost of ads. Higher Ad Rank results in better ad positions and can potentially lower the cost per click (CPC) for advertisers.
