Focus on two questions when reading per creator results:
Which creators to scale? Positive ROAS against target, sufficient spend behind the read, and content matching the hooks and angles that win
Which creators to pause? Zero conversions at sufficient spend, negative ROAS after the signal window, or an audience fit that did not land
Rule of thumb: give every creator a 7 day signal window with at least 150 to 200 euro of spend before making a scale or pause decision.
