1. Why AI Words Kill Your Reach
Every second, thousands of creators publish posts drafted with ChatGPT, Claude, or generic AI writing assistants. And because large language models are trained on average internet text, they default to predictable statistical patterns.
When readers see words like *"delve"*, *"tapestry"*, or *"in today's fast-paced world"*, their brain detects an unedited chatbot within 400 milliseconds. They scroll past without reading the first line.
Before you publish your next draft, run it through our free LinkedIn AI detector to highlight flagged words, calculate your 0–100 Human Score, and get surgical line-by-line fixes.
LinkedIn's Delivery Test shows your post to a small initial sample of 50 to 100 connections. If those first readers scroll past because your hook sounds like corporate filler, distribution stops cold.
The Initial Test Cohort
LinkedIn does not need a special AI classifier to punish robotic drafts. The moment your opening hook sounds like a machine, dwell time plummets and the algorithm cuts off distribution.
2. The Academic & Philosophical Slop List
Standard LLMs love high-flown, pseudo-intellectual phrases that no real founder ever says across a table. Cut these immediately:
| ❌ Flagged AI Word / Phrase | Why It Fails | ✅ What to Write Instead |
|---|---|---|
| In today's fast-paced world... | Empty filler that wastes the first 50 characters. | Cut completely. Start directly with the lesson or number. |
| Delve into / Let's delve | Academic cliché never spoken out loud. | Say 'Look at', 'Examine', or start with the point. |
| Navigate the landscape | Vague abstraction with zero setting. | Name the real space: 'In B2B sales' or 'In our market'. |
| A rich tapestry of... | Classic statistical marker of GPT models. | Say 'A mix of' or simply list the specific components. |
| Embark on a journey | Overly dramatic for a routine business milestone. | Say 'We started' or 'I spent 6 months building'. |
| At the end of the day | Universal verbal crutch that adds zero value. | State your conclusion directly without preamble. |
3. Corporate Buzzwords Readers Tune Out
Corporate buzzwords sound important while saying nothing. High-performing creators replace abstractions with concrete numbers, names, and milestones:
| ❌ Corporate AI Buzzword | Grounded Human Replacement |
|---|---|
| Leverage | Say 'Use'. |
| Game-changer | State what actually changed, with an exact number. |
| Elevate your brand | Say 'Book 3 qualified calls per week'. |
| Seamless integration | Say 'Took our team 15 minutes to set up'. |
| Robust framework | Explain what the framework handles without breaking. |
| Synergy across teams | Say 'Our sales and engineering leads sat together'. |
| Empower clients to thrive | Say 'Helped clients close $40k in new ARR'. |
| Move the needle | Say 'Increased demo conversion from 2% to 6%'. |
4. Giveaway Formatting: Em-Dashes & Emoji Bullets
Beyond individual words, synthetic text has distinctive structural giveaways:
1. **The Excessive Em-Dash (—):** LLMs overuse long dashes to chain clauses together. Real humans use periods, commas, or start a new short line.
2. **The Symmetrical Emoji Bullet List:** A rocket (🚀) on bullet 1, a checkmark (✅) on bullet 2, a lightbulb (💡) on bullet 3, each followed by a bold header and a generic tip.
3. **The 'It's Not X, It's Y' Contrast:** *"It's not about working harder, it's about working smarter."* Drop the faux-philosophical contrast and state your thesis plainly.
4. **Hollow Engagement Closers:** *"Agree? Let me know in the comments 👇"*. Readers ignore generic calls to comment. Ask a provocative question that only an experienced peer would care to answer.
5. The 'Say It Out Loud' Replacement Rule
The simplest test for any LinkedIn post is the **Coffee Table Test**:
Read your draft out loud at normal conversational speed. If you would feel embarrassed or pretentious saying a sentence to a founder over coffee, delete it.
Humans speak in short sentences, occasional fragments, and grounded specifics. AI writes in balanced, multi-clause paragraphs full of qualifying adjectives. When in doubt, simplify.
Actionable Checklist
Delete every sentence that contains delve, unlock, or leverage
Replace every em-dash with a comma, full stop, or line break
Ensure at least one concrete number, dollar amount, or date is in the post
Turn 'Agree?' into a real, non-obvious question
Read the first 90 characters out loud to verify the hook stops the scroll
