All of these might be tricky for a newbie developer. This is why hyper-casual publishers and developers usually work together. While the engineers are responsible for the technical side of the process, publishers run the advertising and testing.
For example, at Ducky, developers test
video ideas of the hyper-casual game. They send us prototypes and receive all those metrics and market feedback results in 24 hours.
However, for a proper understanding of testing results, it's not enough to know the meaning of digital marketing abbreviations. It is also important to understand which values of CPM, CTR, and CPI indicate that the game is worth releasing and scaling.
Understanding how things work allows developers to hack their way to their first "hit" and further "hits" faster. And speed is crucial in this genre.
