A content topic is a theme your content keeps returning to. Some people call these content pillars. Three to five is normal. Each one has a share of your output and subtopics beneath it. You edit them in My Brand, on the Profile tab.
Why they matter more than they look
Explore in Videos is built from them. Along with creators like the ones you follow, the topics are what Vamos matches videos against.
That has a direct consequence. Empty topics mean Vamos cannot match anything to what you make, and Explore has little to go on. Vague topics produce a vague feed.
They also shape what your weekly brief counts as relevant, and what a Routine treats as your subject when you ask for ideas.
Writing good ones
A content topic is narrower than a category and broader than a subtopic.
Fitness is too broad to match anything usefully. How to squat is too narrow to fill a topic. Training around a full-time job is a content topic, because it excludes things and a video either fits it or does not.
Under each topic, add the subtopics you actually cover. Those do the matching work.
Shares
Each topic carries a percentage of your output. Set them to reflect what you actually post rather than what you intend to post, because that is what makes the ideas in chat match your real mix.
Keep at least one
The product will stop you removing the last one. Without any topic there is nothing to build a feed from.
Content topics and core ideas are different
A content topic is what you talk about. A core idea is what you believe about it.
Training around a full-time job is a content topic. Consistency beats intensity for anyone with a job is a core idea. Vamos uses content topics to decide what is relevant and core ideas to decide what position to write from.
