Advertising Platforms & Infrastructure

An ad server is the technology that stores ads and decides, in the moment, which one to deliver to a given slot — then serves it and records what happened. It is the plumbing beneath every campaign, handling delivery, rotation, targeting rules and measurement.
Store the creative. Ads and their rules live in the server.
Receive a request. A page or app asks for an ad to fill a slot.
Decide and serve. Rules pick the right ad and deliver it.
Log the result. Impressions, clicks and conversions are recorded.
Delivery. Getting the right ad into the right slot.
Rotation. Sharing slots across multiple creatives.
Targeting rules. Serving by audience, geo or context.
Measurement. Counting what was served and what happened.
Central control. One place to manage delivery across sites.
Consistent measurement. A single source of truth for counts.
Flexibility. Rules and creative can change without touching pages.
Discrepancies. Server counts can disagree with platform counts.
Latency. Slow serving hurts the user experience.
Complexity. Rules can grow tangled over time.
Privacy. Serving and logging must respect consent.
