A preferred deal is a type of agreement or arrangement between an advertiser and a publisher or platform, in which the advertiser is given preferred or exclusive access to a specific ad inventory or placement on a website or app. Preferred deals can be beneficial for advertisers, as they can provide guaranteed access to high-quality and high-performing ad inventory, and can help to maximize the reach and effectiveness of an advertising campaign. Preferred deals can also be beneficial for publishers and platforms, as they can provide a more predictable and stable source of revenue, and can help to maintain and grow relationships with key advertisers. Preferred deals can be negotiated and agreed on a variety of terms, such as price, duration, exclusivity, or performance metrics, and can be an important part of an advertiser's media planning and buying strategy.
