Summarized by AI, July 2, 2026. Original” What Users Post and Engage With on LinkedIn: A Mixed Methods Study
Most LinkedIn advice comes from people whose job is giving LinkedIn advice, which should make you suspicious. So here’s something rarer: an actual peer-reviewed study of 1,001 individual users’ posts, coded by topic and compared on reactions, comments, and reposts. The headline finding is an inversion: the content people post most (self-promotion, thought-leadership) performs worst, and the content people post least (praising others, marking observances) performs best. Here’s what the AI thinks that means in practice, in ten rules.
Do
1. Make someone else the subject of your post. Posts thanking, congratulating, or acknowledging a specific person – what the researchers call “Interpersonal” posts – won more head-to-head engagement comparisons than any other category, for both reactions and comments. They were also under 10% of the feed. The feed is oversupplied with self-promotion and starved of other-promotion, so post what’s scarce.
2. Tag the people you name. The researchers’ leading theory for why Interpersonal posts dominate is mechanical: tags trigger notifications, notifications extend reach. It’s the closest thing to a free lunch on the platform.
3. Put the insight in the post, not behind the link. Link-heavy posts underperformed, plausibly because clicking the link takes the reader off-platform before they react or comment. Write the post so it’s worth reading even if nobody clicks. The link is a footnote, not the payload.
4. Post about causes and observances you actually have standing on. “Observance” posts – holidays, awareness months, social causes – were only 5% of the sample but went undefeated in reactions and dominated reposts. The caveat is mine, not the paper’s: a hollow holiday post from someone with no track record on the subject is exactly the content r/LinkedInLunatics was built to mock.
5. Match the post type to the metric you actually care about. Want reposts and reach? Business content – job openings, announcements – is what people find easiest to re-share. Want conversation? Interpersonal and personal posts draw comments. Want people to read your article? That’s click-through rate, which the study couldn’t measure – meaning a link post with modest reactions might be quietly doing its job. Don’t optimize for applause when you wanted readers.
Don’t
6. Don’t open with “I’m happy to share that…” The researchers used that exact sentence as the taxonomic example of a career-update post. When academics use your opener as a category label, your opener is dead. Same graveyard: “thrilled to announce,” “humbled and honored.”
7. Don’t expect thought-leadership to pay off in likes. “Expertise” posts – professional insights, industry takes, sharing articles – were the second most common category and won exactly one of seven head-to-head comparisons. The market for insight on LinkedIn is glutted. If you post expertise anyway (I do, it’s the job), do it knowing the reaction count will lie to you.
8. Don’t write the parable. The mundane-anecdote-becomes-business-lesson genre – the recruiter who taught you about resilience, the six-year-old who explained leadership – is the single most-mocked format on the platform. The paper notes that badly executed insight posts seem to get judged more harshly than other content, not less. Cliché isn’t just an aesthetic problem; it’s an engagement risk.
9. Don’t blend intentions. The researchers found 74 posts that couldn’t decide what they were – advice that turns into a sales pitch, gratitude that’s secretly a career announcement – and had to build precedence rules just to code them. Readers detect the bait-and-switch too. One post, one intention. If it’s an ad, be an ad.
10. Don’t treat any of this as physics. The study is observational: no controls for follower count, credibility, post age, or job type, one post per user, and a sample skewed toward Dallas-Fort Worth. “This category got more engagement in this sample” is a heuristic, not a law. But given that the average sampled user posts less than once a year and a third had never posted at all, the honest conclusion is that the bar is on the floor. Posting anything original, regularly, already puts you ahead of most of the billion people on the platform.
A note on methodology: The researchers manually collected the most recent public post from 1,001 individual LinkedIn users (one per user), found by searching “Dallas,” “Fort Worth,” and “Dallas Fort Worth” – so the sample skews toward that region. Posts were pulled between January and June 2024, but with an average post age of 499 days, the content is predominantly from the 2022-2024 era, with some older stragglers – which means it’s almost entirely from before AI-generated posts flooded the platform. Each post was single-coded into one of five categories (Business, Personal, Expertise, Interpersonal, Observances), and engagement was compared using non-parametric tests on reactions, comments, and reposts, with the top 1% of viral outliers removed. It’s observational and descriptive – no controls for follower count, credibility, or post age – so treat the findings as patterns, not predictions. Published 2026 in SAGE Open.
