In this episode of TraderTalkTV, ExchangeWire’s CEO, Ciaran O’Kane, is joined by Mathieu Roche, co-founder and CEO at ID5, to discuss linking IDs across domains. 

In this session, O'Kane and Roche cover:

- how brands and publishers currently communicate through DSPs and SSPs

- the impact that the end of the third-party cookie has on the use of IDs in the buying process

- how ID5 link IDs across domains using deterministic and probabilistic methods, and why it's important to use both approaches to provide both accuracy and scale.
