"Pick one narrow niche and never deviate"

"Pick one narrow niche and never deviate"
The dogma: the algorithm needs you boxed into a single topic or it can't categorize you. Beginners obey because it sounds disciplined.

TikTok categorizes per-video, not per-account. It reads each clip's content, captions, and who engages, then routes it. Your account doesn't carry a fixed "niche tag" the algorithm consults.

What's true: niching down helps your audience know what to expect and helps you get good at one format faster — those are human reasons, not algorithmic ones. You can absolutely post two adjacent topics. Consistency of quality matters more than consistency of subject.
