## What the LinkedIn cheat sheet is {#what-it-is}

The cheat sheet is a free, documented encyclopedia of the rules that make a LinkedIn post perform. Not a list of tips read somewhere: each rule is tied to a behavior actually observed across a base of **1 million analyzed LinkedIn posts**.

You can browse it without installing or connecting anything. Each rule has its own detail page with statistics and real example posts, so you see not just the rule but what it looks like in practice.

## How the rules are organized {#rule-families}

Rules are grouped into families so you quickly find the lever that matches your current problem: a hook that falls flat, a post that's too dense, text that prompts no reaction.

### Hooks and the opening line {#family-hooks}

The most critical family. The first line decides whether your post gets read or skipped in the feed. We document opening patterns here: open question, shock number, tension, clear promise, a first line that cuts before the « see more » fold.

### Structure and storytelling {#family-structure}

How you sequence your ideas: a story before the lesson, a logical progression, an ending that invites comments. This family covers the architecture of the post, from the first word to the last line.

### Formatting and readability {#family-formatting}

Reading comfort on mobile: short sentences, line breaks, one idea per block, no wall of text. The same content can perform or flop depending on its layout, and this family documents what makes a post readable in two seconds.

### Engagement levers {#family-engagement}

Everything that prompts a reaction: a call to comment, a clear stance, social proof, native content over outbound links. This family gathers the triggers of comments and shares.

## How each rule is validated {#validating-rules}

Each rule is tested against the base of **1 million analyzed LinkedIn posts**. We check whether the described pattern truly correlates with engagement, or whether it's folklore repeated without evidence.

An honest caveat: this is observation, not a controlled experiment. Correlation is not causation, and a post's performance also depends on timing, your audience and current events. The cheat sheet gives you solid footholds, not a guarantee of virality.

## Applying the rules without sounding robotic {#apply-without-robot}

The trap is stacking tactics until you get a post that looks perfect on paper and reads hollow. The rules are guardrails, not a template to fill in mechanically.

Pick two or three levers per post, keep your voice, and leave room for your own story. The best use of the cheat sheet is to understand why a rule works, then adapt it to your style instead of copying it word for word.

## From rules to writing with LinkPost {#toward-linkpost}

The cheat sheet teaches you the rules. LinkPost makes you write with them: it **generates 25 variants per topic**, scores **300+ factors** with a **33-criteria** virality prediction and **27 factors personalized** to your style, then lets you schedule and analyze your publications.

The cheat sheet is the free tool. There's no free trial of the full product: LinkPost is the next step when you want to go from rules to posts that are written, scheduled and measured over time.

## A sample of high-impact rules {#data}

> A qualitative sample of high-impact rules documented in the cheat sheet.

| Rule | What it says | Why it works |
|---|---|---|
| Hook in the first line | Put your strongest idea before the « see more » fold | The first line decides whether you're read or scrolled past |
| One idea per block | Break into short sentences, separate with line breaks | The feed is read on mobile, vertically and at a glance |
| Ask a question | Open or close on a real question to your audience | A question gives an explicit reason to comment |
| Native content over links | Keep the value in the post, not in an outbound link | The feed favors what keeps people on the platform |
| Story before the lesson | Tell a concrete case before drawing the takeaway | A story builds the emotional pull that gets people to the end |
| A clear stance | Choose an angle sharp enough not to stay lukewarm | Measured controversy is a comment driver |

> A viral rule isn't a law: it's a pattern observed across a very large number of posts. You use it as a foothold, never as a promise of results.
