Banner Format & Sizes
Standardizes Ad Formats
The most commonly used types of display are the standardized ad formats from IAB. Before IAB introduced standardized ad formats, the digital advertising landscape was fragmented, with each publisher using different ad specifications. This lack of consistency created inefficiencies, making it difficult for advertisers to scale campaigns across multiple platforms
