TL;DR
Open with the role you want and what you do - not your job history. Write in first person, keep it to 200-300 words across 3-5 short paragraphs. Include 2-3 specific skills or outcomes you are known for, then a clear call to action. Use the exact job titles and skill names from postings you want to appear for. Your headline and summary together are what LinkedIn recruiter search surfaces first.
LinkedIn has over 1 billion members. Recruiters do not browse profiles at random: they run searches, filter by keyword, and scan the first lines of what comes back. Your About section - what most people still call the LinkedIn summary - is one of the few places on your profile where you control the text that search indexes and recruiters read. Most people either leave it blank or paste in a version of their resume. Neither works.
Here is how to write a summary that actually earns recruiter contact.
What the LinkedIn About section actually does
The About section serves two functions, and most people only think about one of them.
The first is keyword indexing. LinkedIn uses your profile text in its search algorithm for recruiters. If a recruiter searches for "Python backend engineer" and your summary says "server-side developer", you will not appear in that search. The About section, along with your headline and job titles, is where LinkedIn looks for the terms that match a recruiter's query. This is the function that gets you found.
The second is the pitch. Once a recruiter opens your profile, the About section is often the first block of connected prose they read - your headline is just a label, and your job list is a set of bullet points. The summary is where you explain who you are, what you are good at, and what you are looking for. This is the function that turns a search result into an InMail.
Write for both. Use the language from job descriptions you want to appear in, then give the recruiter a reason to reach out.
The structure that works
A strong LinkedIn summary follows a four-part shape. You do not need to use every part in a separate paragraph - this is a guide, not a template.
Hook: who you are and what you do
Open with your current role or the role you are targeting, and the clearest one-line description of your work. Not your career history. Not "I am a passionate professional." State what you do, at what level, and in what domain. This is also where your most important keyword belongs.
What you bring: skills and outcomes
Name 2-3 things you are specifically known for, ideally framed as outcomes rather than responsibilities. "I have led migrations to cloud infrastructure across three fintech products" is more useful to a recruiter than "I have cloud experience." Be specific, and use the language that job descriptions use.
Where you are headed
One or two sentences on the kind of work you want next. You do not have to say "I am open to new roles" explicitly here - but you should give a recruiter a sense of direction. If you want to move from individual contributor to management, say so. If you want to stay in the same role but at a larger company, say that.
Call to action
End with a single clear sentence inviting contact. "Open to engineering leadership roles - feel free to reach out." or "Happy to talk about any SaaS operations or RevOps opportunities." Keep it direct. This is the line that turns a curious reader into a message in your inbox.
Worked examples
Here is how the structure looks in practice for two different profiles. These are illustrative, not real people - the point is to show the pattern.
Software engineer (5 years experience)
| Weak version | Stronger version |
|---|---|
| Passionate software engineer with 5 years of experience in web development. I love solving problems and learning new technologies. Looking for my next opportunity. | Backend engineer with 5 years building Python and Go services for high-traffic consumer products. Most recently at [Company], where I led the migration of a monolith to microservices and reduced p99 latency by 40%. Strong background in distributed systems and Postgres. Looking for senior or staff IC roles at product companies working on complex data problems. Open to remote or London-based positions - feel free to reach out. |
The stronger version uses specific job-description language (Python, Go, microservices, distributed systems), gives a concrete outcome (40% latency reduction), and closes with a clear CTA and preferred location. The weak version would not appear in a search for "Python backend engineer" and gives a recruiter no reason to open an InMail.
General professional (operations, 8 years experience)
| Weak version | Stronger version |
|---|---|
| Experienced operations professional passionate about driving business results. Skilled in project management, team leadership, and process improvement. Looking for new challenges. | Operations manager with 8 years scaling B2B SaaS post-sales teams. I have built and run customer success, onboarding, and support functions from scratch - most recently taking a 4-person CS team to 22 while keeping NPS above 70. I work best at the intersection of process design and people management. Now looking for Head of Operations or VP Customer Success roles at Series B-D companies. Based in Berlin, open to hybrid. Happy to chat if that sounds relevant. |
The stronger version names specific skill sets (customer success, onboarding, support), gives a measurable outcome (4 to 22 headcount, NPS above 70), signals target company stage, and ends with a clear CTA. All practitioner-level illustrative examples; not drawn from a specific case.
How LinkedIn search works and why keywords matter
When a recruiter searches LinkedIn Recruiter or LinkedIn's standard search, the algorithm scans your headline, job titles, skills section, and About section for matching terms. The exact phrasing matters more than most people realise: LinkedIn does not automatically equate "ML engineer" with "machine learning engineer", or "growth marketing" with "demand generation", unless both terms appear in your profile.
The practical step is to look at job descriptions for roles you want, note the specific titles and skill names they use most, and check whether those exact terms appear in your summary and headline. If the jobs you want say "Salesforce" and your profile says "CRM", add "Salesforce" explicitly. If they say "TypeScript" and you only list "JavaScript", add the specific term.
The keyword audit
Open three or four job descriptions for roles you want. Highlight every job title variant, every named tool, and every skill phrase. Check how many of those exact terms appear in your LinkedIn headline, About section, and skills section. Fill the gaps - not as a wall of keywords at the bottom, but worked naturally into your summary prose.
Your headline is the highest-weight keyword field because it appears in every search result and every piece of content you interact with. "Software Engineer at Acme Corp" is weaker than "Software Engineer - Python, Go, Distributed Systems". Use the character limit (220 characters) to pack in your role, domain, and 2-3 key skills.
Should you turn on Open to Work?
If you are actively job searching, yes. LinkedIn's own data shows that members who indicate they are open to new opportunities are significantly more likely to be contacted by recruiters. The fear that your current employer will see it is understandable, but LinkedIn offers a setting to show the signal only to recruiters (not publicly and not to employees of your current company). If you are worried about visibility, use that setting rather than leaving the signal off entirely.
The “Open to Work” flag is separate from what you write in your summary, but both work together. The flag surfaces you in searches filtered for active candidates; the summary then makes the case for why a recruiter should reach out.
Common mistakes that cost you recruiter contact
Writing in third person
Third person reads as distant and formal on a platform designed for direct professional connection. "John is an experienced engineer who..." sounds like a press release, not a person. Write "I am" and "I have" throughout.
Copy-pasting from your resume
Your resume is a structured list of roles. Your LinkedIn summary is a pitch. A list of bullet points transplanted into the About box does not read well and wastes the one place on your profile where you can write in a connected, human voice. Use your resume as a source of facts (titles, dates, outcomes) but write the summary fresh.
No call to action
A summary that ends with your last achievement leaves the recruiter with no next step. One sentence at the end - "open to senior product roles, feel free to message me" or "currently exploring fintech and marketplace opportunities" - dramatically lowers the friction for someone who is interested but not certain you are looking.
Too long
LinkedIn shows roughly 300 characters before the “see more” cut-off on mobile and in some search contexts. That means your opening two sentences need to hook the reader on their own. Beyond 300-400 words, most recruiters will not read further. Keep the body focused and end clearly.
Jargon that does not match job descriptions
Internal company terminology, role-specific nicknames, and vague buzzwords ("dynamic professional", "results-oriented leader") do not appear in recruiter searches and do not help a recruiter quickly understand what you do. Use the exact language from job descriptions.
LinkedIn profile and active job search together
A strong LinkedIn profile builds inbound: recruiter contact, connection requests, and messages from companies whose roles you might not have found yourself. But inbound alone is rarely enough for an active job search, and inbound tends to surface roles on a recruiter's timeline, not yours.
The complement is outbound - applying directly to posted roles, early, with tailored materials. Our guide on why applying early matters shows the data on how much timing affects response rates. Matching your resume to job descriptions is the tailoring step that makes each application land. For a complete picture, the Complete Job Search Guide covers how these channels work together from first search to offer.
MORT is an AI job-matching platform that scans thousands of company career pages, scores every job 0-100% for compatibility with your skills and experience, and generates a tailored resume for each application. It complements the inbound you build through a strong LinkedIn profile - covering the active outbound side and making sure every application you send is tailored to the specific posting.
Frequently asked questions
How long should a LinkedIn summary be?
LinkedIn allows up to 2,600 characters in the About section, but only the first 300 characters or so appear before “see more”. Aim for 200-300 words of useful content - enough to show who you are, what you do, and what you are looking for, without padding. Anything beyond 400 words risks losing a recruiter before they reach your call to action.
Should I write my LinkedIn summary in first person or third person?
Always write in first person. Third person reads as stiff and impersonal on a platform built for direct professional connection. Write “I lead product teams” not “Jane leads product teams”. First person also lets you use a natural, conversational tone that holds a recruiter's attention.
What keywords should I put in my LinkedIn summary?
Use the exact job titles, skill names, and tool names that appear in job descriptions for the roles you want. LinkedIn search treats your About section as a keyword surface: if a recruiter searches for “Python backend engineer” and your profile says “server-side developer”, you will not appear. Mirror the language in postings you want to show up for, without keyword stuffing.
Should I turn on "Open to Work" on LinkedIn?
Yes, if you are actively looking. LinkedIn's own data shows that members who signal openness to new opportunities are significantly more likely to be contacted by recruiters. You can choose to show the green banner publicly or share your status only with recruiters, not your current employer.
How often should I update my LinkedIn summary?
Update it whenever your target role changes, when you gain a new significant skill or achievement, or when a job search is not producing recruiter contact. If you have not updated it in over a year, it is almost certainly out of date. A 15-minute refresh at the start of a job search is one of the highest-return tasks you can do.
What is the difference between a LinkedIn headline and a LinkedIn summary?
Your headline is the short line under your name - it is the primary keyword signal in LinkedIn recruiter search and appears everywhere your profile is shown. Your summary (the About section) is the deeper pitch: context, achievements, and a call to action. Both matter. The headline gets you into search results; the summary converts a recruiter from curious to interested.
Build inbound on LinkedIn. Back it up with outbound.
A strong LinkedIn profile brings recruiter contact to you. MORT covers the outbound side: it scores thousands of new jobs daily for fit with your skills and experience, then generates a tailored resume for each application, so every role you apply to gets a specific case for why you are the right fit.
