10 LinkedIn post formulas that earn comments, not just likes.
The ten shapes BrandAgent’s Writer Agent uses — what each one is, when it works, and the mistake that ruins it.
Formulas built on proof
Cost Collapse — price an expensive role or tool honestly, then show the version you can build instead
The Receipt — one thing that happened, told straight, ending on the detail that surprised you
Build Teardown — what you built and what each part does, one mechanism per line, no pitch
The Honest Loss — something that failed, what it cost, and what you do instead now
Formulas built on a point of view
The Rule That Never Breaks — one operating principle, the three places people break it, and why it holds
Contrarian Mechanism — everyone optimises X; the real lever is Y, then the steps of how Y works
Quiet Comparison — old way and new way as matched line items, no adjectives
Formulas built for reach
The Unlock List — a counted list of what changed, one mechanism per line
Deadpan Joke — an impossible source delivers a real work pain, completely straight
Playbook Giveaway — what the asset is, what is inside, a three-step ask
The mistake that ruins all ten
Vagueness. Every formula works on a specific number, name or moment. Without one, it reads like every other post in the feed.
Questions
Which formula works best? The one that fits what you actually have to say. Proof formulas need real numbers; point-of-view formulas need a real opinion.
Should every post pitch? No. A useful rule is about one in four — the rest earn the attention the pitch needs.
