An ad exchange is essentially a trading platform, whereas an ad network acts as an intermediary: it aggregates ad supply from publishers, and matches it with advertiser demand. It does this by collecting inventory from a list of publishers, or buying impressions in bulk from an ad exchange. It then sorts them and resells the space to advertisers — saving them time and resources.

Ad exchange trends for 2024 and beyond
Ad exchanges are here to stay, but how might they evolve? Here are a few trends to watch:
AI driving improvements
As with most areas of digital marketing, artificial intelligence is revolutionizing how ad exchanges work. AI can analyze vast amounts of data in real time, facilitating improved targeting and instant campaign optimization. And machine learning capabilities can help predict campaign success and even highlight fraudulent behavior.
Privacy first
Ad exchanges depend on user and behavioral data to get relevant ads in front of the right audiences.

What’s the difference between an ad exchange and an ad network?
Ad exchanges and ad networks both connect advertisers with publishers.

A mobile ad exchange is one tailored to the mobile environment. It enables advertisers to buy space within mobile apps, drawing on behavioral data for sophisticated targeting.
