The PPC data is updated on a daily basis.
During the early stages of each day, Amazon's API will transfer data for the day before the current day.
Changes Visible after around 1 Hour
Changes made in Sellics should become visble in Seller Central approx. 1 hour later and vice versa.
It can also take a few minutes before the actual change (in Sellics) is displayed in Sellics - but it should be visible in the change log immediately.
However, remember that the changes you make in Seller Central will not be logged in your Sellics Change Log or "Analyze" section.
New Campaigns after First Impressions
Amazon's API will transmitt new campaigns as soon as they have generated impressions.
As the API only transmits its data (inlcuding impressions) on a daily basis, new campagins will appear at the earliest on the next day.
Also, this article shows how to find, add or edit campaigns in Sellics.
Automation Rule Conditions checked Daily
The rules in the automation feature will check whether the specific conditions were met daily over night (when we receive the newest PPC data).
More on how the rules work can be found in this article (click here).
