How to Spot a Legit Career Expert on LinkedIn

LinkedIn is a hellscape that job seekers cannot escape from, no matter what they do.

That might seem harsh, but between rolling out a barely useful AI job search and admitting that much of the engagement on its platform is AI slop it is now trying to reduce, there is no getting around the fact that LinkedIn is not what it used to be.

To make matters worse? Everyone who is posting seems to be a "Founder," "Owner," or "CEO" who wants you to know they have the secret to success in life. And for the low low price of a follow or a mention, you can get those secrets too.

So what is the problem? The problem is that LinkedIn now has more grifters speaking up than people with actual industry knowledge.

It matters to you as a job seeker because if you follow the advice of these "professionals," you may be hurting your job prospects or sending networking requests to people who cannot actually help you.

When I logged onto my LinkedIn feed just now and typed in "HR," the first three posts served to me were AI-generated slop, all the exact same advice with a different AI-generated image on each. It actually makes me sad how easy it was to get examples of generic advice without even trying.

What do these people actually know about HR? If I wanted a Google search or Claude to explain HR to me, I would just ask. None of these people are showing that they have any knowledge beyond what we could get from any other source on the internet.

But I can see where these types of posts would be enticing to people. On the surface, many of the people generating this AI content on LinkedIn can sound authoritative.

"I reviewed 10,000 resumes and here is the one word that got people hired."

"Recruiters spend 6 seconds on your resume, so do this instead."

"I helped 400 people land six-figure jobs, and they all did this one thing."

Let me tell you something as someone who has been in corporate tech for nearly 15 years and a hiring manager for a lot of that time: a large share of the people lecturing you about hiring on LinkedIn have never actually done the hiring. Many are selling a course, a coaching package, a resume template, or a newsletter, and the "advice" is just the bait (to potentially get themselves hired too). This is a guide to telling the two apart, so you can follow the people who know what they are talking about and scroll past the people performing.

Why Your Feed Got So Much Worse

This is not your imagination, and it is not nostalgia. LinkedIn genuinely used to be a quieter place where people in your industry shared real work. Two things changed it.

First, LinkedIn decided it wanted to be a content platform. It poured money into cultivating creators (reportedly a $25 million investment and a team of around 60 creator managers) because more posting means more time on the app. The incentive shifted from sharing something useful to simply producing volume.

Second, generative AI made that volume effortless. The results are stark. One analysis by Pangram Labs of more than a million posts found that over 40% of long-form LinkedIn posts are now fully AI-generated, the highest rate of any major platform. A separate study by Originality.ai put the figure for long posts even higher, around 54%, and found those AI-written posts earned roughly 45% less engagement from actual humans. In plain terms: close to half of the "insights" scrolling past you were written by a machine, often to feed an engagement algorithm rather than to help you.

The core problem

LinkedIn does not fact-check what people claim. It does not verify that you held the jobs on your profile, or the titles, or the results you brag about. A startup founder once proved this by changing his own job title to "CEO of LinkedIn" and watching the platform publish it without a single check. If the platform will not verify these claims, you have to.

Start With One Question: What Are They Selling?

Before you evaluate anyone's advice, figure out how they make money. This single question explains most of what you are seeing.

There is nothing wrong with selling a legitimate service. Plenty of excellent career coaches, resume writers, and recruiters earn a living this way, and they are worth every dollar. The problem is the person whose entire business model depends on keeping you anxious. If someone needs you to believe the job market is a terrifying puzzle that only their $499 course can solve, their incentive is not to inform you. It is to scare you, then sell you the cure.

Watch for this tell. Genuinely helpful content leaves you more capable on its own. Grift content leaves you feeling like you cannot possibly do this without buying the next thing. If every post ends in a link, a "DM me," a waitlist, or a "comment the word GUIDE and I'll send it," you are not reading advice. You are reading an ad attempting to be covert.

If they are not selling a course or a product, they may just be inflating their self-importance to land career opportunities they would not normally qualify for. Maybe not as scary for your wallet as the course sellers, but you can still waste time taking advice from, or doing outreach to, someone who has no clue what they are talking about.

How to Audit Anyone's Profile in Two Minutes

When a post stops you, do not react to it yet. Click the name and read the actual profile first. You are looking for whether the person has really done the thing they are teaching. Here is the quick version of what I check.

1. Does the experience match the expertise?

This is the big one, and it is exactly the red flag you would expect. If someone is positioning themselves as a hiring authority, they should have actually hired people, at a real scale, for real companies. Three years of total work experience stacked with four "Founder" and "CEO" titles at companies you have never heard of is not a resume. It is a costume. Anyone can write "Founder" under a one-person LLC they registered last spring. The title tells you nothing about whether they have ever made a payroll decision, sat in a calibration meeting, or delivered a single layoff.

Look at the timeline honestly. When did they actually hold the operating role they reference? Was it a decade in the field, or six months as a junior recruiter before pivoting full-time to selling recruiting advice? A short stint is not disqualifying on its own, but it should match the confidence of the claims.

2. Do the numbers survive basic arithmetic?

The big round numbers are where it falls apart. "I reviewed 50,000 resumes" is a favorite. Do the math. If you spend even two careful minutes on each resume and work full time, reviewing 50,000 of them takes years of doing literally nothing else. "I placed 1,000 people in six-figure roles" from someone three years into their career is not a track record, it is a fantasy.

Real practitioners tend to cite specific, smaller, believable numbers because they are remembering actual events rather than inventing impressive ones.

3. Is the advice specific, or could it apply to anyone?

Real expertise is specific. It knows that advice for a senior software engineer is different from advice for a new nurse, which is different again for a mid-career marketer. Grift content is deliberately vague, because vague content applies to the largest possible audience and therefore gets the most engagement.

Those three posts above, the same advice dressed up with a different AI image on each? A perfect example of this.

"Just be confident and tell your story" is not a strategy. It is someone giving the same advice a basic LLM would. And remember, if you cannot act on a post without buying something, it was never meant to help you act.

4. Does it read like a human or like a prompt?

Once you know almost half of long posts are machine-written, you can more easily spot the pattern. The one-line opener designed to stop your scroll. The single-sentence paragraphs stacked like dominoes. The fake-profound pivot ("But here is what nobody tells you."). The tidy list of three. The closing question fishing for comments.

None of that is automatically dishonest, but when a post has the full template and no specific, lived detail inside it, you are looking at content built for getting engagement from the algorithm, not for you.

5. Can you verify anything they claim?

For anyone you are considering paying, treat it like the hiring decision it is. Check whether their LinkedIn timeline matches their website and their claims. Look for a real, findable identity rather than a stock photo and a first name (there is a huge amount of bots creating fake accounts for engagement, here is how you block those).

If they cite a credential, confirm it comes from a recognized body and not an official-sounding organization they appear to have invented. The scammy end of this world now includes people buying or leasing real aged LinkedIn accounts, and people who keep a prestigious former employer listed as "current" long after they were let go, precisely because the logo sells.

The Red Flag and Green Flag Cheat Sheet

Keep this next to you while you scroll. Most accounts are a mix, so weigh the overall picture rather than disqualifying someone over a single item.

Red Flags (be skeptical)	Green Flags (worth your time)
Many "Founder" or "CEO" titles stacked on only a few years of total experience	An operating track record that actually matches what they teach
Enormous round numbers (50,000 resumes, 1,000 placements) that do not survive arithmetic	Specific, modest, believable numbers and named examples
Every post funnels to a course, DM, waitlist, or "comment a word below"	Posts that are useful on their own, with the occasional honest plug
Advice so vague it could apply to literally anyone in any field	Advice tailored to a role, level, or industry, with real tradeoffs named
Content that keeps you anxious so you buy the cure	Content that leaves you more capable and calmer
Perfect AI template, zero lived detail, fake-profound one-liners	A recognizable human voice, specifics, and the occasional unglamorous truth
Unverifiable claims, invented-sounding certifications, prestige logo kept long after they left	A findable identity and claims that line up across profile, site, and posts

A quick field test

Imagine two accounts both telling you how to beat the applicant tracking system. The first belongs to someone with 12 years at a known company, who posts a short walkthrough using a real (anonymized) example and never asks for a cent. The second belongs to someone with 3 years of experience, four "Founder" roles, a headline full of emojis, and a post that ends "the full system is in my $297 masterclass, link in comments." Same topic, opposite credibility. Now you can see it at a glance.

Credentials Are a Signal, Not the Whole Story

One fair caution (to keep my view impartial): do not use this as an excuse to dismiss everyone who is building a business. Some of the most useful career voices on LinkedIn do sell coaching or courses, and they are good precisely because they came from the work first. A recruiter with real reps, a hiring manager who has actually written the job description and sat in the debrief, a person who changed careers and documented exactly how, all of these can be worth following even when they also have something to sell.

After all, I am writing these posts based on real expereience and do so anonymously in order to be able to speak more candidly. I wouldn't want someone to discount this advice since my LinkedIn profile isn't linked to this website.

The point is not "never trust anyone who monetizes." The point is to make them earn it. Does the free content stand on its own? Do the claims survive a two-minute check? Does the experience fit the expertise? When the answer is yes, a paid offer is just a service, and a reasonable one. When the answer is no, the paid offer was always the entire point.

What to Do With Your Feed Instead

Spotting the grift is only half the job. The other half is replacing it with something that actually moves your search forward.

1.   Curate ruthlessly. Mute or unfollow the accounts (or flag their posts as AI Slop) that leave you anxious and sold-to. You are allowed to. Your feed is a tool, not an obligation.

2.   Follow operators, not just talkers. Prioritize people who still do the work (recruiters at real companies, hiring managers in your field, practitioners one or two steps ahead of you) over full-time "thought leaders."

3.   Treat every big claim as a hypothesis. Before you act on a viral tip, sanity-check it against a second source or against how hiring has actually worked in your own experience.

4.   Spend your time on people, not posts. The part of LinkedIn that genuinely produces offers is the networking layer: messaging a real recruiter on a posting, reconnecting with a former colleague, asking a specific question of a specific human. Reading advice is not the same as doing the search.

5.   Never pay out of panic. If a post made you feel like you must buy something right now or stay unemployed forever, that feeling is the product. Close the app, sleep on it, and decide tomorrow when you are calm.

Silence the LinkedIn Lunatics

LinkedIn is still useful. Worse than it used to be? Absolutely.

But much of the real career networking and messaging still happens on this platform, so you have to use it no matter the downsides.

The connections are real, (some of) the job postings are real, and some of the people sharing advice are the genuine article who will quietly make your search better. But the feed is now roughly half machine-written and heavily tilted toward whoever is best at selling, which means the burden of judgment has shifted to you.

So judge. Ask what they are selling, check whether the experience matches the expertise, run the big numbers through basic math, and refuse to pay anyone out of fear. Three years of experience and four "Founder" titles is a costume, not a credential. Once you can see that, the noise will quiet down and the few voices actually worth listening to will start to surface more easily.
