The display visibility rate refers to the percentage of times a digital advertisement is actually seen by a user on a webpage or app. This metric takes into account factors such as ad placement, size, and user behavior to determine the likelihood of an ad being viewed. A high display visibility rate indicates that an ad is effectively reaching its intended audience and has the potential to generate more engagement and conversions. It is an important measure for advertisers to track in order to optimize their campaigns and ensure maximum visibility for their brand or product.
