Primary means you create that format natively for that platform because it performs best there. Repurpose means you adapt it from a primary piece you already made — same idea, reformatted. Skip means it’s not worth your time on that platform yet.
Master one home base first, then add a second only when the first is consistent. Most creators overreach — three platforms done well beats five done poorly. The matrix shows you which formats carry over so you’re never starting from zero.
It weights each platform by how many Primary and Repurpose formats it has, then splits your weekly hours proportionally — roughly 70% creating and 30% engaging. Platforms with more Primary formats earn more of your time.
