# One promise, a few formats, one slot

Story / Test and publish / Posting. Checked 2026-11-13.

A stranger understands what the account is for from any single post.

- Use when: Running an account as a series.
- Phrase: write the account's promise in one line; every post keeps it, in two or three repeatable formats, at one fixed time in the audience's evening

## Watch out

- On one measured account the median of the ten posts after a change of promise was 33.6 times the ten before; the formats had not changed. One account cannot prove the cause; it is the only visible change. (measured; Director Chair field notes on short-form video (one TikTok account, 233 posts and 27 measured clips, read 30 Oct 2026))
- A step wears off: the median fell to about a quarter between the first and the second half of October, as the examples began to repeat. Change the sources before changing the format.

Give me a step-by-step plan I can follow this week, for a short video about [your product], for [your audience]. The technique is one promise, a few formats, one slot: a stranger understands what the account is for from any single post. How it works: write the account's promise in one line; every post keeps it, in two or three repeatable formats, at one fixed time in the audience's evening. It is right for: running an account as a series. On one measured account the median of the ten posts after a change of promise was 33.6 times the ten before; the formats had not changed. A step wears off: the median fell to about a quarter between the first and the second half of October, as the examples began to repeat. Be concrete: numbers, seconds and settings, no theory. Ask me one question first if something you need is missing.
