Why Am I Seeing Blank Squares in Hour-of-Day Reporting?

Blank squares in your hour-of-day report usually mean no impressions were served during those times.

By default, Ui.Marketing campaigns are set to run between 5 AM and 12 AM (midnight), based on the end-user’s local browser time. Unless the campaign’s schedule is specifically adjusted, no ads will serve between 12 AM and 5 AM.

You may also notice lower traffic between 4 PM and 6 PM, which corresponds to midnight UTC, when the reporting day resets. By then, most impressions for the day are typically already delivered.
