Quick answer
Ten About-section examples you can adapt, written for engineers, sellers, founders, and students, plus the structure that makes each one work.
Your LinkedIn summary (the About section) is the only part of your profile written entirely in your own words, and only the first 300 or so characters show before the 'see more' fold. The examples below show how people in different roles win that first line and back it up quickly. Steal the skeleton, swap in your specifics, and keep your own voice.
The structure every good summary shares
Strip away the surface differences and good summaries follow the same four-beat arc: a hook that earns the 'see more' click, a plain statement of what you do and for whom, proof in the form of numbers or named outcomes, and a single call to action.
The hook does the heaviest lifting. LinkedIn truncates the About section at roughly 300 characters, so a first line like 'Experienced professional with a passion for innovation' guarantees nobody expands it. Open with a claim, a number, or a tension instead.
Pro tip: Write your summary last line first. When you know the action you want a reader to take, the rest of the summary becomes an argument for taking it.
Examples: engineering & data
Technical summaries fail when they read like a skills inventory. The examples below lead with the problem solved, not the stack used — the stack shows up as supporting detail.
- Data analyst: open with the decision your analysis changed — 'My dashboards killed a $2M project that deserved to die' beats any tool list.
- DevOps/SRE: lead with uptime or incident numbers; hiring managers scan for scale ('40 services, 3 regions, 99.99%').
- Engineering manager: one line on team size and scope, one on a shipped outcome, one on your management philosophy, in that order.
I make slow systems fast. Last year that meant cutting checkout latency 60% for a marketplace doing $40M GMV. Before that, rebuilding a data pipeline that saved 30 engineer-hours a week. I work mostly in Go and TypeScript, but the constant is the same: find the bottleneck, measure it, kill it. Open to senior backend roles — DMs open.
Examples: sales, marketing & founders
Go-to-market summaries have one job: make the right buyer or partner feel 'this person gets my problem'. Write to that one reader.
- Account executive: name your buyer and their pain in line one ('I help CFOs stop paying for software nobody uses'), then one quota-attainment proof point.
- Marketer: pick the metric your role owns (pipeline, CAC, organic traffic) and show its before/after under your watch.
- Consultant: state the transformation and the client type; end with exactly how to start ('Book a 20-minute intro call — link above').
Every LinkedIn tool wanted to write posts for me. None of them sounded like me. So I built CannerAI — an AI content workspace that learns your voice, drafts your posts, and schedules them via official APIs. Bootstrapped, profitable, and shipping weekly. I post what I learn along the way: growth experiments, SEO data, and the unglamorous parts of founding. Follow along, or try the product free.
Examples: students & career changers
With little work history, the summary carries more weight, not less. The move is to lead with direction and evidence of momentum — projects, coursework applied, communities — rather than apologizing for inexperience.
- Student: name your target field, the most impressive thing you've built or researched, and what you're looking for (internship, first role, mentorship).
- Recent graduate: one concrete project with a result beats a GPA; recruiters search keywords, so name the skills you actually used.
I spent six years managing restaurants. Now I build the tools I wish I'd had. Mid-career switch into software: 18 months of nights and weekends, three shipped projects (one with 2,000 users), and a CS certificate. Restaurant management taught me the things bootcamps can't — staying calm at peak load, and that every system is only as good as the person using it at 11pm on a Friday. Looking for a junior role on a team that ships. Say hi.
Mistakes that kill a summary
The same handful of mistakes shows up in most summaries that get skipped: opening in third person, listing adjectives instead of outcomes, writing one unbroken wall of text, and ending without telling the reader what to do next.
- Third-person voice ('John is a seasoned leader…'): the About section is the one place first person is expected.
- Buzzword stacking: 'passionate, results-driven, innovative' says nothing a proof point wouldn't say better.
- No line breaks: LinkedIn has no rich text, so blank lines are your only formatting. Use them every 2-3 sentences.
- Zero CTA: a reader who finishes your summary is the warmest audience you have. Give them exactly one next step.
Pro tip: Read your summary out loud. If a sentence is something you would never say to a person at a meetup, rewrite it or cut it.
