The Seattle Times is the latest of 50 sites signed by the Washington Post for its Zeus Performance advertising technology stack.

Zeus general manager Jarrod Dicker says the system has proved publishers can increase ad monetisation without having to sacrifice user experience or limit ad supply. "Working with an innovative publisher like the Seattle Times is going to further accelerate our ability to drive this mission for publishers across the globe," he says.

In their first month since rolling out Zeus, the Times saw their ad viewability more than double while CPMs and RPMs showed double-digit growth. In addition, Zeus has improved the overall site speed of seattletimes.com by some measures as much as 50 per cent.

Seattle Times advertising vice president Gary Smith says the publisher wanted to simplify its ad tech stack to improve page load times, and improve viewability. "The Zeus platform has achieved both goals for us."

Zeus Performance is one of three tools built in-house by The Post that comprise the Zeus Technology Suite.
