Understanding GET Requests and Their Role in Ad Tracking
· 2h ago · Originally reported by PPC Land
A GET request is an HTTP method used by browsers to retrieve resources from a server. In digital advertising, GET requests are fundamental to tracking pixels, impression beacons, and win notices, which help measure ad delivery and performance.
Why it matters
Knowing how GET requests work helps explain how ads are tracked and measured online, which is essential for understanding digital advertising operations.

Tracking pixel
A tracking pixel is a tiny piece of code, historically an invisible 1x1 image, that loads when a page or ad is viewed and reports that event to a server.
Impression
An impression is one instance of an ad being served and counted as displayed to a user; it is the basic unit that most online advertising is bought and sold by.
