Why is my daily budget not being output?

In short: In addition to the maximum daily budget, the advertising delivery always depends on the number of visitors to your online shop.

With retargeting, only those users who have previously visited your online shop are addressed again. This means that the potential of advertising delivery is always linked to the number of visitors. Especially shortly after the start of a campaign, the daily budget can often not yet be fully used as there must first be enough retargeting markers in our ad server.
