# LinkedIn Profile Checker A LinkedIn profile checker is a tool that scores your headline, About section and profile photo against clear rules, such as LinkedIn's character limits, an opening line that lands before "see more" and a way to contact you. **Key facts:** $0 - No sign-up - Runs in your browser, nothing uploaded - 14 rules, each with a one-line fix - Checks the 220 and 2,600 character limits Updated October 2026 Scoring runs in your browser. Your text and photo are never uploaded or stored. ## How to use it 1. **Paste your headline and About section:** Copy both from your LinkedIn profile and paste them in, keeping the line breaks. Add two to five keywords a recruiter would search for if you want the keyword checks, and your profile photo if you want it scored too. 2. **Read the score and the top three fixes:** Every rule shows pass, improve or fix with one line on what to change. A pass earns the rule's full points, improve earns half and fix earns none; rules that could not run are left out of the score. The three changes that move it most are listed first. 3. **Edit, recheck, then update LinkedIn:** Rewrite in the boxes and watch the score change as you type. When you are happy, paste the new text back into LinkedIn: on desktop, the pencil icon in your profile's intro edits the headline and the pencil on About edits the About section. ## What is a LinkedIn profile checker? A LinkedIn profile checker reads the parts of your profile people see first, the headline, the About section and the photo, and tests them against rules you can see. This one checks length against LinkedIn's limits, whether your role is near the front of the headline, whether the About opens with something worth reading before the "see more" cut, sentence length, voice, buzzwords, emoji, all caps and whether you tell people how to reach you. Paid LinkedIn profile optimizer tools and human profile reviews do the same job with more judgment. A rules based checker cannot tell whether your claims are true, whether your tone suits your industry, or whether a recruiter in your field would care about what you lead with. What it does well is catch the mechanical problems in seconds, so a human review, or your own second read, can spend its time on substance. ## How LinkedIn shows your headline and About section The headline field takes up to 220 characters and the About section up to 2,600. LinkedIn counts spaces and line breaks as characters, and so do the counters in the checker. Most people never see the full text. Next to your name in search results, comments, invitations and messages the headline is usually cut short, so the first few words do the work. The About section shows only its opening lines until someone taps "see more". LinkedIn does not publish an exact cut, and it changes with screen width, so the checker uses conservative estimates: about the first 60 characters of the headline and the first 200 characters of the About section, roughly what a phone shows. - [LinkedIn Talent Blog: About section limit (2,600 characters)](https://www.linkedin.com/business/talent/blog/product-tips/linkedin-profile-summaries-that-we-love-and-how-to-boost-your-own) ## What should my LinkedIn headline be? A strong headline answers three questions in one line: what you do, who you do it for or what you specialise in, and why anyone should believe you. A simple formula is Role | Specialty or audience | Proof or outcome. The role goes first, in the words people actually type into LinkedIn search, such as "Payroll Specialist" rather than "People Ops Ninja". If you have no headline, LinkedIn fills the field with your current job title and employer. That is accurate but rarely persuasive, and it says nothing about what you want next. If you are job hunting, lead with the role you want and your strongest skill, and put "open to" phrasing at the end, not at the start. Separators such as a vertical bar or a middle dot keep a long headline scannable. Use one or two emoji at most, never all caps, and leave out adjectives you would not put on a CV. ## LinkedIn headline examples for tech and product roles Software engineer: Backend Engineer | Go, PostgreSQL and payments infrastructure | Building systems that stay up on the busiest day of the year Product manager: Product Manager, B2B SaaS | Onboarding and activation | Turning user research into roadmaps engineering teams can ship Data analyst: Data Analyst | SQL, Python and Tableau | Helping retail teams make pricing and stock decisions from data they already have UX designer: Senior Product Designer | Design systems and accessibility | Making complex enterprise tools feel simple IT support: IT Support Specialist | Microsoft 365, Intune and endpoint security | Keeping a hybrid office of several hundred people working ## LinkedIn headline examples for sales, marketing and HR Account executive: Enterprise Account Executive | Cybersecurity SaaS | Helping security teams replace legacy tools without a painful migration Marketing manager: Content Marketing Manager | B2B SEO and editorial strategy | Building content programs that sales teams actually use Social media: Social Media Manager for consumer brands | TikTok, Instagram and community | Turning followers into repeat customers Recruiter: Technical Recruiter | Hiring engineers for climate tech startups | Candidate first, always HR: HR Business Partner | Employee relations and change management | Helping growing companies keep their culture through restructures ## LinkedIn headline examples for healthcare, education, law and finance Nurse: Registered Nurse, ICU | Critical care and patient education | Calm under pressure, clear with families Physician: Family Physician | Preventive care and chronic disease management | Accepting new patients in Austin Teacher: High School Chemistry Teacher | Lab based learning | Making science click for students who think they hate it Lawyer: Employment Lawyer | Representing employees in discrimination and wage claims | Plain English advice, no surprise fees Accountant: CPA | Tax planning for small businesses and freelancers | Fewer surprises in April Financial advisor: Financial Advisor for physicians and dentists | Student debt, practice ownership and retirement planning ## LinkedIn headline examples for founders, consultants and freelancers Founder: Founder and CEO at a scheduling startup | Helping independent clinics cut no shows | Hiring engineers in Berlin Consultant: Operations Consultant for ecommerce brands | Fulfillment, inventory and 3PL selection | Former warehouse manager Freelance writer: Freelance Copywriter for B2B tech | Website copy, case studies and email | Clear words for complicated products Real estate agent: Real Estate Agent in Denver | First time buyers and relocations | I answer the phone on weekends Therapist: Licensed Therapist (LMFT) | Couples and anxiety | Online sessions across California ## LinkedIn headline examples for students, graduates and job seekers Student: Computer Science Student at Ohio State | Seeking summer 2027 software engineering internship | Python, React and AWS Recent graduate: Marketing Graduate | Analytics, paid social and copywriting | Open to entry level roles in New York Job seeker: Supply Chain Analyst | Demand planning and SAP | Open to new roles after a company wide restructure Career changer: Former Teacher moving into Instructional Design | Articulate 360 and adult learning | Building training people finish The pattern holds at every stage: the role you want comes first, then the skills that prove you can do it, then what you are open to. ## How to write a LinkedIn About section Think of the About section as five short parts. Open with one sentence that says what you do and for whom, short enough to read complete before "see more". Follow with how you do it: your specialty, methods or tools. Add proof: a project, a type of client, a result. Add a line on what you are looking for or how you like to work. Close with a contact line, an email, a website or a plain "message me about". Write in the first person. "I help" reads as you talking; "she helps" reads as a press release, and switching between the two in one section reads as copy pasted. Keep sentences short, most under 20 words, and add a line break every two or three sentences, because LinkedIn keeps them and a single block of text is where readers give up. There is no right length. A short LinkedIn summary of three or four sentences works for many people; a longer one is worth it when you have specific proof to add. Use the space for specifics, not for adjectives, and put your main keyword in the opening line, because that is the part people actually read. ## LinkedIn About section examples Product manager example: "I help B2B software teams turn first time users into daily users. For the last several years I have run onboarding and activation for SaaS products, from the first research interview to the experiment that ships. I like problems where the data says people are stuck and nobody yet knows why. My best work comes from sitting close to engineering and design and keeping the roadmap short. If you are working on activation, message me here. I am always happy to compare notes." Registered nurse example: "I am an ICU nurse who believes good care includes the family in the waiting room. I work nights in a busy medical ICU, caring for patients on ventilators and after major surgery, and I precept new graduate nurses on our unit. Outside the hospital I volunteer at a community clinic teaching people how to manage diabetes at home. I am interested in nurse educator roles. You can reach me here on LinkedIn." Career changer example: "After ten years teaching high school English, I now design training that adults actually finish. Teaching taught me how people learn: in short steps, with practice, and with feedback that arrives quickly. I now build e-learning in Articulate 360 and run workshops for onboarding teams. My portfolio has three recent courses, linked in the Featured section. I am looking for instructional design roles in healthcare or tech. Let's talk." Founder example: "I build software that keeps small clinics on schedule. Before starting the company I managed front desks for a group of physical therapy clinics and watched good practices lose hours to no shows and phone tag. Our product handles reminders, waitlists and rebooking so the front desk can look after the people in the room. We are hiring engineers and talking to clinic owners. Email me at the address on our website." ## Short LinkedIn summary examples Accountant: "I am a CPA who helps freelancers and small businesses keep more of what they earn. Tax planning, bookkeeping clean ups and plain answers by email. Message me before you file." Software engineer: "Backend engineer working on payments. I like boring, reliable systems and the tests that keep them that way. Currently open to staff level roles." Recruiter: "I hire engineers for climate tech startups. If you want work that matters and a recruiter who tells you the salary on the first call, say hello." ## Common profile mistakes the checker flags Buzzwords top the list. Words like passionate, results driven, motivated, dynamic and team player are claims anyone can make, so readers skim past them. Replace each with the evidence that made you reach for it. The checker lists every stock phrase it finds. The next most common problems are structural: an About section that opens with "Hello and welcome to my profile", a single block of text with no line breaks, sentences of forty words or more, a section written about yourself in the third person, and no way to get in touch at the end. Each one takes a minute to fix. Emoji and capitals are small things that add up. A rocket or two can work in a creative field, but a row of emoji pushes your role out of the visible part of the headline, and screen readers announce every one. All caps reads as shouting; keep capitals for real acronyms. ## Your LinkedIn profile photo The photo sits next to your headline everywhere it appears, often before anyone reads a word. Add yours to the checker and it runs four quick checks on your device: a face is found, the photo is sharp, the lighting is usable and your face fills enough of the frame. For a full score out of 100 that also rates your eye line and background, run the same photo through our LinkedIn photo checker. LinkedIn accepts JPG or PNG profile photos from 400 x 400 to 7680 x 4320 pixels, up to 8 MB, and shows them in a circle. If your photo passes but is cropped badly, the profile photo cropper sizes it for the circle. If you need a new photo altogether, Smart Headshots AI turns your own selfies into LinkedIn headshots. - [Check your photo in detail](https://www.smartheadshots.ai/tools/headshot-photo-checker) - [Crop it for LinkedIn](https://www.smartheadshots.ai/tools/profile-photo-cropper) - [See LinkedIn headshots](https://www.smartheadshots.ai/linkedin-headshots) ## Privacy: your text stays on your device Everything you paste is scored in your browser by a small set of rules that ships with the page. There is no AI model reading your profile, no account and no server call; reloading the page clears the boxes. The optional photo is decoded and checked on your device as well; the face detection model is downloaded to your browser, and the photo never leaves it. ## What the LinkedIn profile checker scores | Rule | Passes when | Flagged when | | --- | --- | --- | | Headline length | 30 to 220 characters | Empty or over 220 (fix), under 30 (improve) | | Role up front | A role or your keyword sits in the first 60 characters | It appears later, or not at all | | Value, not just a title | A second part: who you help, a specialty or proof | A bare job title, or only "seeking opportunities" | | About length | 400 to 2,600 characters | Empty or over 2,600 (fix), under 400 (improve) | | Opening line | First sentence fits in about 200 characters and gets to the point | Opens with a greeting or a buzzword, runs past the cut, or skips your keywords | | Sentence length | Sentences average 22 words or fewer, none over 40 | Average over 22 (improve) or over 30 (fix) | | Short paragraphs | No block over 700 characters | A block over 700 (improve) or over 1,200 (fix) | | Voice | First person throughout | Third person, mixed, or no "I" at all | | Contact line | An email, a link or a phrase such as "message me" | No next step anywhere | | Target keywords | Every keyword you entered appears | Some missing (improve) or all missing (fix) | | Buzzwords | None of the listed stock phrases | One or two (improve), three or more (fix) | | Emoji | Up to 2 in the headline and 10 in the About section | More than that | | All caps | Normal capitalisation | A headline in capitals (fix), or more than two shouted words | | Profile photo | All four quick photo checks pass | One check flagged (improve), two or more or no face (fix) | ## FAQ ### What should my LinkedIn headline be? Your headline should say the role you do or want, who you help or what you specialise in, and one piece of proof, in that order. Put the role first in the words people search, because the headline is often cut short next to your name. Keep it under LinkedIn's 220 character limit and skip adjectives like passionate or motivated. ### How do I edit my LinkedIn profile headline? On desktop, open your profile and click the pencil icon in the intro section next to your name, then edit the Headline field and save. In the mobile app, open your profile and tap the pencil icon in the same intro area. The field accepts up to 220 characters. ### How long should a LinkedIn About section be? Long enough to say what you do, how and for whom, with one piece of proof and a contact line, and never more than LinkedIn's 2,600 characters. For many people that is three to five short paragraphs. What matters most is the opening sentence, because only the first lines show before "see more". ### Can ChatGPT write my LinkedIn profile? It can write a first draft, and it is a reasonable way to get unstuck. Drafts from AI tools tend to lean on the same stock phrases this checker flags, such as passionate and results driven, and they cannot know your real results. Paste the draft here, cut the filler, and replace every claim with something you actually did. ### What is the 4-1-1 rule on LinkedIn? The 4-1-1 rule is a content marketing rule of thumb, not a LinkedIn policy: for every six posts you share, four come from other people, one is your own original content and one is promotional. It is about what you post, not your profile, so this checker does not score it. A clear profile matters more when your posts start bringing people to it. ### What is a good headline for a CV? A good CV headline is one short line under your name that states the role you are applying for and your strongest qualification, such as "Registered Nurse, ICU, with critical care certification". It follows the same formula as a LinkedIn headline but is shorter and tailored to each job. Many people reuse the first part of their LinkedIn headline. ### Is my profile text uploaded when I use the checker? No. The rules run in your browser and nothing you paste is sent to a server or stored. If you add a photo, it is checked on your device too, and reloading the page clears everything. ## More free tools - [LinkedIn Photo Checker](https://www.smartheadshots.ai/tools/headshot-photo-checker): A LinkedIn photo checker is a tool that scores a profile picture out of 100 for light, sharpness, framing, eye line and background, rating the photo rather than the person in it. - [Circle Crop Tool](https://www.smartheadshots.ai/tools/profile-photo-cropper): A circle crop tool cuts a photo into a round profile picture and saves it as a PNG with transparent corners, or as a square sized for each platform. - [Background Changer](https://www.smartheadshots.ai/tools/headshot-background-changer): A headshot background changer is a tool that separates the person in a portrait from the background behind them and replaces that background with plain white, grey, a brand color or a blurred version of the original. - [Cost Calculator](https://www.smartheadshots.ai/tools/headshot-cost-calculator): A headshot cost calculator estimates what professional headshots cost from a studio photographer, an on-site corporate photographer or an AI headshot service, using published prices for your city, team size, looks and retouching. - [Headshot Prompt Generator](https://www.smartheadshots.ai/tools/ai-headshot-prompt-generator): An AI headshot prompt generator builds a ready-to-paste prompt that asks ChatGPT, Gemini or another image tool to turn your own photo into a professional headshot while keeping your face unchanged. - [Profile Picture Tester](https://www.smartheadshots.ai/tools/profile-picture-tester): A profile picture tester, or pfp tester, previews your photo as the round or rounded square avatar that LinkedIn, Slack, Microsoft Teams, Gmail, Zoom and X show, from the large profile view down to the small icons beside comments and chat messages. - [Background Picker](https://www.smartheadshots.ai/tools/headshot-backgrounds): A headshot background picker shows which professional backgrounds suit each industry and a LinkedIn photo, with examples, color codes and the attire that pairs with each one. - [Color Analysis Quiz](https://www.smartheadshots.ai/tools/color-analysis): A color analysis quiz is a short set of questions about your undertone, hair, eyes and contrast that sorts you into a seasonal color type and shows which colors flatter you. - [Face Shape Detector](https://www.smartheadshots.ai/tools/face-shape-detector): A face shape detector is a tool that measures the length of a face and the width of its forehead, cheekbones and jaw in a photo to estimate whether it is oval, round, square, oblong, heart, diamond or triangle shaped. ## Related headshot packs - [LinkedIn Headshots](https://www.smartheadshots.ai/linkedin-headshots): A LinkedIn headshot is a head and shoulders portrait, framed for the circle crop LinkedIn applies, that represents you on your profile, in recruiter search results and beside every message and comment you post. - [Professional Headshots](https://www.smartheadshots.ai/professional-headshots): A professional headshot is a head and shoulders portrait, evenly lit against a plain or softly blurred background, used to represent you on company websites, staff directories, email signatures, conference programs and press coverage. ## Links - [Create your headshots](https://www.smartheadshots.ai/start) - [All free tools](https://www.smartheadshots.ai/tools) - [Home](https://www.smartheadshots.ai/)
