GIJC23 – Masterclass: Digging into Digital Advertising

More than $550 billion was spent on digital ads last year — on everything from banners and video ads to sponsored tweets and pop-ups of every sort. What’s behind this mega-business? The systems used to buy and sell digital ads are vast, complicated, poorly understood, and rife with fraud and deception.

This workshop provides a hands-on guide to tools and techniques used to investigate digital ads on websites, apps, and social media networks. Learn the basics of programmatic ads, how to distinguish between display, content, and affiliate ads, and how to use ads.txt and other information to uncover ownership and other connections. Bring your laptop!
