Different ad campaign platforms like Google Ads or Facebook Ads have faced criticism for using software which are compared to blackbox software. Only original settings and results are visible, with no indication of how the software works internally via an algorithm. It is thus difficult for users to optimize their ad campaigns.
Blackbox
In digital marketing, the term blockbox is used to indicate a campaign management software internal to a platform, and which is inaccessible or deliberately omitted to a platform user.
