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 and targeted advertising, as it can analyze data to reach specific audiences. The technology behind programmatic advertising includes algorithms and data analytics, which help optimize ad performance. Advertisers can track how well their ads are doing and adjust their strategies accordingly. This approach not only saves time but also maximizes the effectiveness of ad spending by ensuring ads reach the right people at the right time.
