Step-by-step explanation:
The ad format that supports pre-bid verification with Integral Ad Science (IAS) is display ads. IAS provides ad verification and optimization services that can protect against ad fraud, ensure ads are seen, and ensure they are displayed in brand-safe environments. Pre-bid verification is a feature that assesses various metrics, such as viewability, fraud, and brand safety, of an ad placement before the bid is made.
By integrating pre-bid verification, advertisers can make more informed decisions and optimize their ad spend. While display ads are known for this capability, other ad formats may also offer similar features, depending on the ad platform and technology available. The ad format that supports pre-bid verification with IAS (Integral Ad Science) is video ads. IAS offers pre-bid verification for video ads to ensure the quality and safety of the ad placements. This allows advertisers to have more control over where their video ads appear and verify their viewability, brand safety, and ad fraud detection before bidding on inventory.
