ID5 Connect is a centralised cookie matching service designed to simplify user ID synchronisation, reduce bandwidth and processing costs, and improve match rates between ad tech platforms.

By centralising cookie matching for the digital advertising industry, ID5 Connect creates economies of scale that benefit platforms and publishers. ID5 transforms a mostly client-side process into a server-side match table distribution service, reducing page latency, data leakage, and privacy risks. Thanks to ID5 Connect, publishers can improve user experience and better monetise data and inventory, and ad tech platforms can operate more efficiently.
