Private deals, also known as deal IDs, are special agreements between advertisers and publishers that give access to premium ad placements at set prices. These deals are useful for affiliates because they offer more control over where ads appear and often come with better traffic quality. Instead of bidding in the open market with everyone else, deal IDs let you buy ad space directly on websites that match your niche. This can lead to better results because your ads are seen by more relevant users. It also reduces the risk of showing up on low-quality sites. Has anyone here used private deals to improve display campaign performance?
