There is no magic number but rough anchors help: close to daily on TikTok, several times a week on Instagram feed plus daily stories, weekly on YouTube. The real rule is consistency you can sustain without dropping quality. Posting daily badly hurts more than posting three strong times a week. Pick a cadence, hold it and raise it only when quality holds.
How often to post
The right number is the one you can keep at quality.
Rough cadence by platform
Near daily on TikTok, a few times a week on Instagram.
Consistency over volume
A steady pace beats sporadic bursts.
Never trade quality for frequency
Posting daily badly hurts more than it helps.
