Google AdSense vs Quantcast: What are the differences?

Developers describe Google AdSense as "A program that allows bloggers and website owners to make money by displaying Google ads". It is a program run by Google through which website publishers in the Google Network of content sites serve text, images, video, or interactive media advertisements that are targeted to the site content and audience. On the other hand, Quantcast is detailed as "A technology company specializing in real-time advertising and audience measurement". It is a digital marketing company that provides free audience demographics measurement and delivers real-time advertising.

Google AdSense and Quantcast can be primarily classified as "Advertising" tools.

Some of the features offered by Google AdSense are:
