Don't Do These 3 Things on LinkedIn. Recruiters Will 'Spot Them From a Mile Off.' Make sure you're not making these common professional faux pas that can scare off hiring managers before you even land an interview.

In all likelihood, whoever gives you your next job will look at your LinkedIn profile. It's the first stop on any recruitment train, and it's sure to show up in the search results when someone plugs your name into Google. A more dire way to think about that is: whoever doesn't give you your next job will also have looked at your LinkedIn profile. What made them choose someone over you? Of course, it's impossible to understand the inner workings of a company's hiring decisions, but it is possible to sidestep silly, off-putting blunders that recruiters see all day, every day.

Here, we spoke with Anastasia Pshegodskaya, the director of talent acquisition at Remote, a global HR platform, about the most common mistakes she sees on LinkedIn profiles, and how to avoid them.

1. Spelling and grammar errors

"If your LinkedIn posts are littered with grammatical errors, this could throw up some concern for the hiring manager," says Pshegodskaya, "especially if the role you're applying for requires written fluency and strong communication. Linguistic fluency could be the deciding factor between two very strong candidates, and a high level of grammatical accuracy indicates strong attention to detail that's invaluable to many hiring managers."

Correct (but not overly formal) grammar and spelling is the kind of thing people assess unconsciously and immediately, like good eye contact or a firm handshake. It helps you seem comfortable and capable. Errors, on the other hand, get people's attention for the wrong reasons — like a limp handshake, or looking at your phone when someone is sharing something important. It suggests a disinterest or unawareness about how you're presenting to others.

According to a recent study by the tutoring platform Preply, which analyzed data from thousands of LinkedIn profiles, the most commonly misspelled words across the board are "management," "programming," "I'm," and — no surprise to us at this publication! — "BIZ Experiences."

The most common grammar mistake on LinkedIn, the study found, was "bachelor's," as in the following (correctly written) example: "I have a bachelor's degree." The time you would not use an apostrophe would be if you are citing your full degree: "I have a Bachelor of Arts."

English is a complicated and inconsistent language that stumps even professional writers at times. The good news, Pshegodskaya says, is that, "There are plenty of online tools to help overcome common grammatical slip-ups. For example, Grammarly will help you pick up on easy-to-miss errors."

2. Sharing posts without substance

If grammar and spelling are "first impression" fodder for your LinkedIn persona, posts you write are the equivalent of telling an interviewer what your professional experience has taught you, or pitching an investor on why your business matters. This is the real substance that prospective bosses and investors are looking for.

"I'd say the most important thing is to ensure your LinkedIn posts have character and add meaningful content to industry conversations online," Pshegodskaya says. "LinkedIn is a platform to showcase your expertise, network and communicate with other professionals, so make sure your content is unique and engaging. It will get hiring managers' attention if you capture a fresh perspective and show a snippet of your personality."

Of course, making unique and engaging content — while capturing a fresh perspective and showing off your personality — is much easier said than done. But it's often a good strategy to start with a story that exemplifies a larger point you want to make. The more specificity the better.

In the internet age, it's very hard to write something truly unique, or come up with a take that's certified fresh, so your best bet is to pull from your own life and professional experience. Often, if I notice myself continuing to think about something I saw or read, particularly if it made me uncomfortable, interrogating that feeling is a good place to start looking for a unique or relatable insight.

3. Relying on content generated by ChatGPT

If you've been reading the headlines about the latest breakthroughs in AI, and wondering if you should outsource some of your strenuous "thought leadership" writing exercises to a chatbot, Pshegodskaya says you should think twice.

"For many hiring managers, any content solely created on ChatGPT or similar bots can be spotted a mile off," she says, adding, "It's often generic."

She isn't totally against using these tools; she just doesn't think you should rely on them for idea generation, or the initial writing process.

"Tools like Grammarly and ChatGPT are great for editing your content, but I'd be cautious about using AI tools to fully generate your LinkedIn posts. My advice is to come up with post ideas first and then run the content through an editing tool to pick up missed grammatical errors before hitting send."
