Guide

You need one honest sentence, a spending cap, and an afternoon. This guide covers the judgment calls the quickstart skips: how to frame a niche, what makes a brief generative, and how to ramp from reviewing everything to approving almost nothing.
Frame the niche, not the brand
The most common first-channel mistake is briefing the system on your company instead of your audience. A niche in marketer.sh is not “our brand’s social presence.” It is a repeatable editorial beat: one audience, one promise, one recognizable angle, delivered daily.
“Content about our productivity app” is a brand. “Two-minute fixes for people who abandon their to-do lists by Thursday” is a niche. The second version tells the ideation engine who it is talking to, what problem recurs, and what a good topic looks like. It also tells the viewer, in the first second, whether this video is for them.
Pick something narrow enough that you could name twenty topics yourself in ten minutes. If you can, the ideation engine can name two hundred, and rank them by what actually performed.
Write the one-sentence brief
Onboarding asks for a single sentence, and the AI drafts the full niche from it: audience, tone, topic pillars, posting plan. The sentence is doing a lot of work, so make it concrete. A useful template:
“[Kind of content] for [specific person] who [tension or desire].”
- Name the person, not the demographic. “Home cooks who meal-prep on Sundays” beats “25 to 40 year olds interested in food.”
- Include the tension. The clause after “who” is where hooks come from. “...who don't want to spend $2,000” generates a hundred videos.
- Skip adjectives about yourself. “High-quality engaging content” adds nothing. The system already tries to be good.
You will get to edit everything the draft proposes, so do not agonize. A specific, slightly wrong sentence produces a better draft than a vague, safe one.
Choose voice and style deliberately
The niche draft comes with a proposed narration voice and visual style. Preview the voice before accepting it; you can audition options right in the review screen. Two rules of thumb serve most channels well.
First, match energy to platform norms in your topic, not to your own taste. Finance and how-to content sustains a calm, mid-pace voice. Fitness and food reward brighter, faster reads. Watch three top posts in your niche and pick the voice that would not feel out of place among them.
Second, commit for at least two weeks. Voice and style are how a feed learns to recognize you. Changing them every few days resets that recognition and muddies your early metrics, because you can no longer tell whether a dip came from the topic or the switch.
Set the cap before the first render
Before anything renders, set the niche's daily cap. For a first channel, $5 to $10 a day is plenty: enough for a daily video, an article, and some ideation, with room to spare. The cap is a hard limit, not a target. A job that would pass it is refused before any money moves.
Why set a cap you won't hit?
Run the trust ramp
Every niche starts in review-before-post mode: the pipeline produces, you approve, then it publishes. Treat the first two weeks as a deliberate ramp rather than a chore.
- Days 1 to 3: review everything. Reject freely and note why. Rejections teach you what to fix in the niche settings, usually the tone or the topic pillars.
- Days 4 to 10: your approval rate should climb past 80 percent. If it does not, tighten the brief instead of grinding through reviews.
- After two weeks: widen autonomy for the formats you trust. Many people keep articles on review and let video publish on schedule, or the reverse. Autonomy is per niche and reversible.
Read early metrics without fooling yourself
Performance data flows back into ideation automatically, but the first days of a channel are noisy and small. Resist the urge to steer on day three. What is worth watching early:
- Completion rate over views. A video that 200 people finish beats one that 2,000 people skip after a second. Completion is the earliest honest signal.
- Spread between your best and worst post. A wide spread means the niche has a hit pattern to find. A flat, low spread usually means the framing is too broad.
- The 30-day view, weekly. The niche performance card ranks top and bottom performers; ideation reads the same list. Check it weekly, not hourly.
By week three the loop is doing its job: topics that worked spawn neighbors, topics that flopped stop appearing, and your role shrinks to the two things a human is genuinely best at, taste and veto.
