Description

A comprehensive overview of this resource

This rum.js script, provided by Google's DoubleClick, is designed for Real User Monitoring (RUM) specifically in the context of online advertising. It operates within the user's browser to collect critical performance metrics related to how web pages and advertisements load and are interacted with. This includes measuring page loading times, ad latency, viewability rates of display ads, and other user engagement signals. The data collected helps advertisers and publishers optimize ad delivery, improve campaign performance, and ensure ads are displayed effectively and efficiently. It works by passively observing network requests, DOM changes, and various browser events to gather performance data without directly interfering with the user experience.
