Ezoic has a Direct Ad orders app which enables you to include your directly sold ad orders in testing and ensure these orders run on Ezoic versions of the site subject to the type of deal and rate agreed with your advertiser.
Here's an article explaining how to set up the direct orders app: https://support.ezoic.com/kb/article/what-is-the-direct-ads-app
If you encounter any issues, such as the deal not delivering impressions, please check the details of the order carefully in the app and check this matches what was agreed with the advertiser. Make sure you have entered the CPM for example, as well as the start and end dates, and how the impressions should deliver. You'll also need to make sure the creative(s) have been added.
