A preferred deal is a type of advertising agreement between a publisher and an advertiser, where the publisher reserves a specific amount of ad inventory for the advertiser at a negotiated price. This type of deal gives the advertiser priority access to premium ad placements, allowing them to reach their target audience more effectively. Preferred deals are often used by advertisers who want to secure specific ad placements on high-performing websites, while publishers benefit from guaranteed revenue and increased control over their ad space. Unlike traditional programmatic advertising, preferred deals offer a more personalized and direct approach to buying and selling ad space, resulting in a mutually beneficial partnership between publishers and advertisers.
