## Description

CMeter activates the Content Meter library on web pages, enabling enhanced measurement for advertising campaigns. Unlike standard meters that report only impressions and clicks, Content Meter captures richer signals about how users engage with content.

This extension helps developers integrate the library to collect data such as user interests, other sites visited, and social/demographic characteristics of the audience, supporting more informed marketing decisions.
