Note
Consistency > timing
TikTok's algorithm rewards posting frequency more than perfect timing
General Rules (From Public Research)
Consistency beats timing. Posting every day at a "bad" time outperforms posting once a week at the "perfect" time. Every study confirms this.
Check your own analytics. These are averages across millions of accounts. Your audience might be night owls or in a different timezone. Platform analytics show YOUR best times — use them.
Batch your content. Creating content in batches (e.g., one session per week) and scheduling it is more sustainable than creating in real-time. Tools like Buffer, Hootsuite, and Later can handle scheduling.
First hour matters most. Engagement in the first 30-60 minutes after posting signals the algorithm to push your content further. Post when your audience is online, not when you're online.
