Stats (i.e. revenue, visits, traffic, earnings) for each day are updated at midday (PST) the following day.
This is because, here at Ezoic, we allow our publishers to leverage the partnerships we have built with many demand sources. They report at different times and with differing frequencies so for most publishers it's better to wait until all the results are in and provide a comprehensive set of updated results.
Please note: Dashboard reporting is not in real-time. Also, revenue reported in the dashboard is estimated and it's not final until the various ad networks report - normally on a net 30-day basis.
