Programmatic Advertising is a method of buying and selling digital ad space using automated technology. Instead of negotiating directly with publishers, advertisers use software to bid on ad placements in real-time. This process allows for more efficient targeting and can reach specific audiences based on their online behavior. The technology behind programmatic advertising includes algorithms and data analytics, which help optimize ad campaigns. Advertisers can track performance and adjust their strategies quickly, ensuring that their ads are shown to the right people at the right time. This approach enhances the effectiveness of online marketing efforts.
