Readers may flag LinkedIn posts that carry a familiar set of signals: an announcement or rhetorical-question opener, em dashes stacking up, buzzword vocabulary, tidy three-item lists, a motivational ending, and no verifiable specifics anywhere in the post. One signal means little. Several together can make the post feel templated. Here are the checks to review.
Check 1: The first two lines
"Thrilled to announce…", "In today's fast-paced world…", "Ever wondered why…?" — these openers are so associated with one-click AI that many readers stop right there. It's the cheapest check and the most common flag. (It's also why LinkedIn's Enhance Post button hurts more than it helps: it produces exactly these openers.)
Check 2: The punctuation and rhythm scan
Check 3: The vocabulary scan
Delve, leverage, unlock, transformative, game-changer, tapestry, testament, journey, elevate. Any one word is innocent; a cluster is a fingerprint. The full list is in our AI slop words and phrases reference.
Check 4: The specificity test — the one that decides it
The strongest check isn't stylistic at all. The reader asks: is there anything in this post only this person could know? A real number, a named tool, an exact error message, a thing that went wrong, a client's actual objection. AI text generated from a thin prompt cannot contain these, so a fluent post with zero verifiable specifics reads as synthetic even when the style is clean. This check has no workaround except writing (or supplying) the specifics yourself.
Check 5: The profile mismatch
Readers who are deciding whether to trust you — recruiters especially — check the post against the person. A junior profile posting sweeping thought-leadership in flawless prose, or someone whose comment replies read nothing like their posts, triggers the flag. Voice consistency across posts and comments is hard to fake at scale.
Check 6: The claim-shaped-nothing test
AI padding produces sentences that are grammatically claims but say nothing: "It's not just about tools — it's about people." "Growth requires embracing change." If a sentence would be equally true in anyone's post about any topic, it counts as evidence of machine writing.
What being flagged actually costs
The penalty usually isn't a comment calling you out. It's silence: the post stops counting as evidence of anything about you.
LinkedIn is a credibility platform — the value of a post is that a specific person with specific experience stands behind it. Recruiters may read posts as a work sample of your thinking and communication. A templated post can count for less. The July 2026 Pangram Labs study (over a million posts scanned; 40%+ of long-form LinkedIn posts reported as fully AI-written) gives context for why some readers review these signals — we covered it in this breakdown.
How to pass every check while still using AI
Readers object to synthetic substance, not AI-assisted editing. Keep the facts, opinions, and specifics yours; review the style tells before posting (the seven patterns, with rewrites). The anti-slop editor marks general patterns and offers optional fixes. Checks about your experience, audience and claims stay with you. Free, no signup.
