AI LinkedIn About optimizer: write an About section that fits your goal
The About section, which many people still call their LinkedIn summary or bio, is the only place on your profile where you write in sentences. Below: what it is for, a four-part structure, fictional examples for job seekers, students, people between jobs, freelancers and people building a reputation, and six steps to write yours. When you want your own judged, Profile Intelligence rewrites it from the facts on your profile, or tells you to keep the one you have.

What is the LinkedIn About section for?
Your headline makes a claim in one line. Your Experience proves it role by role. The About section is the bridge: the one place you can explain, in your own voice, what connects the roles and why someone should care. It is also the longest piece of text on your profile.
LinkedIn used to label this section Summary, and many people still call it their LinkedIn summary or their LinkedIn bio. It is the same field, and everything on this page applies whichever name you search for.
The constraint that shapes everything is the fold. LinkedIn shows the first few lines before a "see more" link, and fewer on mobile. So the About section is really two documents: an opening that has to earn the click, and a body that rewards it.
Most About sections get this backwards. They open with a warm-up sentence ("Experienced leader with a passion for...") and bury the one fact that would have made a stranger keep reading in paragraph three. Fixing the order is often worth more than rewriting a word.
Where the fold falls
Shown to everyone · about 300 characters
Most machine learning projects have a launch date. The harder part is what happens after launch. I build the systems, operating model and ownership around machine learning so it keeps working after the project team moves on. Three of those models… see more
Shown after the click · the rest of the 2,600
…are in daily use in payments, each with a named owner and a retraining schedule. Before that I rebuilt the feature pipeline three forecasting models depended on, cutting the overnight run from six hours to under one. I work best with teams that have shipped a model and are wondering why it is getting worse.
Fictional example from the sample report. Claim above the fold; evidence below it.
A structure for your LinkedIn summary
Four paragraphs, each with one job
You do not need 2,600 characters, and most strong About sections use far less. What matters is that each paragraph answers a question the reader is asking at that moment. The order below suits most readers; who you are writing for changes what leads, and the examples further down show how.
The claim
Reader is asking: “What does this person do?”
What you do, for whom, and the belief or approach that makes it yours. No adjectives about yourself; one idea.
Source: What your roles have in common, said as one sentence. Your headline should make the same claim.
The proof
Reader is asking: “Can they back that up?”
The two or three strongest facts from your career: numbers, named outcomes, things that still run. Each one sentence, told in the role that earned it.
Source: Experience bullets and recommendations.
How you work
Reader is asking: “What would it be like to hire or work with them?”
The kind of problem you are best at, the kind of team, the thing you insist on. Specific enough to put some readers off.
Source: Your roles, or what a recommendation says about you.
What next
Reader is asking: “What do they want from me?”
One line for the reader you chose: a subject you are happy to be approached about, what a first step looks like, or where your work can be seen. Not a keyword list.
Source: The goal you are writing for.
LinkedIn summary examples
LinkedIn About section examples by goal
The same four jobs, bent to a different reader each time. Each group says who is reading and what to lead with, then gives one fictional About. Under each, "Rests on" names what on the fictional profile makes every sentence true: a figure comes from the role that earned it, and a certificate proves only that it is held. The report writes an About to the same rules.
Get hired
Job seekers still in a role
Someone deciding whether to talk to you about a role wants your professional identity in the first two lines, then the level you work at and the problems you can own. Choose your strongest proof rather than walking through every job. It should read like someone worth talking to, not like a pitch.
I am a supply chain planner for consumer goods. I work between sales, production and suppliers, turning a demand forecast into a plan a factory can run.
I own the twelve-week production plan for two plants. I rebuilt the weekly planning meeting around one shared forecast, and forecast error fell from 34% to 21% in a year.
Before that, as a demand analyst for a food distributor, I built the promotions model the sales team used to set orders for seasonal ranges.
I am always glad to talk about sales and operations planning, and about making a plan survive the factory floor.
Rests on: The description of the current role in Experience, which states the plan, the meeting and both forecast figures. The description of the earlier analyst role, which states the promotions model. The two job titles.
Get hired
Students and new graduates
Nobody expects a career yet, so do not write one. An internship, a placement or a student society role is real experience, and it can carry a sentence about what you did. A degree or a certificate says you studied something, not that you have done it at work, so name it as something you hold. Avoid "aspiring": it spends your opening on what you are not yet.
I am a final-year economics student, and the part of the work I enjoy most is the point where a spreadsheet turns into a decision someone can make.
Last summer I interned with a retail analytics team. I built the weekly stock report in SQL and Power BI, and the team adopted it for its Monday trading meeting.
As treasurer of my university hiking society I ran a budget for 120 members and moved our payments from cash to an online system.
I have also completed a professional certificate in data analytics. If you work in retail or consumer analytics, I would be glad to hear what the job looks like from the inside.
Rests on: The degree in Education. The internship in Experience, whose description states the report and its adoption. The society role, also in Experience, whose description states the budget and the move to online payments. The certificate in Licenses & certifications.
Get hired
Unemployed or between jobs
Write about the work, not the search. Put roles that have ended in the past tense, and leave "currently" off them. What you are looking for, or the reason for a gap, is yours to add if you choose to: only you know it. LinkedCheck will not write it for you, because nothing on a profile says it. Your headline can carry the same title; the headline page has examples for people between jobs.
I am an operations manager with nine years in warehouses and last-mile delivery for online retailers, where a missed cut-off turns into an empty shelf by morning.
In my last role I led operations across two distribution sites with 140 staff. I reorganised picking around the products customers order together, and picking errors fell by a third.
Before that I set up the returns process for a new fulfilment site, from an empty floor to 3,000 returns a week.
I am happy to talk about warehouse layout, peak planning and returns.
Rests on: The description of the last role in Experience, which states the two sites, the staff and the fall in picking errors. The description of the earlier role, which states the returns process. The dates on both roles, which give the nine years and show that both have ended.
Win clients
Freelancers, consultants and founders
Someone who might hire you for work needs to recognise their own problem before they care about your career. Open on the problem, say what changes when it is solved and how you help, then prove it. An invitation to work with you belongs only where your profile shows you offer that work.
I work on one problem for independent restaurants: knowing what food and staff cost while there is still time to act on it.
I keep the books weekly rather than monthly, so an owner sees each Monday what the last week cost and which dishes paid for themselves.
Before going freelance I was finance manager for a group of four restaurants, where weekly cost reporting brought food cost down from 33% to 29% of sales in a year.
If that sounds like your kitchen, message me and we can look at one month of your numbers together.
Rests on: The freelance role in Experience, whose description states the weekly books. Services on the profile, which list weekly bookkeeping and cost reporting. The description of the finance manager role, which states the weekly reporting and both food cost figures.
Build a reputation
People who post and want to be known for it
Someone deciding whether to follow you wants the view you hold, the subject it sits in and why you are credible in it. Give them a reason to follow; offer nothing for sale unless you sell something. An About can say what you want to be known for, and your posts are where it shows. The Complete LinkedIn Intelligence Report reads your recent posts and who engaged with more than one; it does not write a better About.
I think accessibility is a design decision, not a checklist you run at the end. It is the subject I come back to.
I have been a product designer for eleven years. On the mobile banking app I work on now, I set up screen reader testing in every release and wrote the design team’s accessibility guidelines.
I hold an accessibility specialist certification, and I care most about forms, colour contrast and making the case for accessible design inside a product team.
If you are working on this too, let us compare notes.
Rests on: The description of the current role in Experience, which states the testing and the guidelines. The dates on the design roles, which give the eleven years. The certification in Licenses & certifications. The opening view is the person’s own framing of that record, not a new fact.
Every About in this section is fictional, written for this page. An example shows a pattern; it cannot tell you what your own profile proves. Check your profile free to see what a stranger concludes you do and what to lead with. The Free LinkedIn Profile Audit tells you whether your About needs changing; the rewrite, where one is justified, is in Profile Intelligence.
The first sentence
Five openers that fail, and what to write instead
These are the openings most About sections start with. A fixed opener with a weak body still beats the reverse.
The adjective stack
“Experienced, results-driven leader with a passion for innovation and a proven track record of success.”
Instead
“Most machine learning projects have a launch date. The harder part is what happens after.”
Every word in the first version is unverifiable. The second is a point of view that only someone who has lived it would hold.
The years count
“With over 15 years of experience in the technology industry, I have...”
Instead
“I have taken three models from proof of concept into daily use in payments.”
Tenure is not an achievement. The number that matters is the one attached to an outcome.
The third person
“Marisol is a seasoned data leader who helps organisations unlock value.”
Instead
“I build the systems and ownership around machine learning so it keeps working after the project team moves on.”
Third person reads as written by someone else. First person is what a reader trusts.
The mission statement
“I believe technology should empower people and transform businesses for the better.”
Instead
“I work best with teams that have shipped a model and are wondering why it is getting worse.”
A belief anyone could hold says nothing. A description of the exact situation you are good in says everything.
The keyword block
“Machine Learning | MLOps | Data Engineering | Python | AWS | Leadership | Agile”
Instead
“I run MLOps for regulated payments platforms: retraining schedules, runbooks, named owners.”
Search reads both. Only one of them tells a reader what you would do on Monday.
What the rewrite changes
Same facts, reordered and made specific
Before
Experienced machine learning and data leader with over a decade of experience delivering data driven solutions for enterprise organisations. I am passionate about building high performing teams and driving innovation through technology.
Throughout my career I have worked across the full data lifecycle, from strategy to implementation, partnering with stakeholders at all levels to deliver measurable business value.
Currently I lead the ML engineering function at Halden Group, where my team has taken three models from proof of concept into daily use in the payments business…
- FoldEverything above "see more" could describe ten thousand people.
- BuriedThe only checkable fact, three models in production, is in paragraph three.
After
Most machine learning projects have a launch date. The harder part is what happens after launch. I build the systems, operating model and ownership around machine learning so it keeps working after the project team moves on.
At Halden Group, three of those models are in daily use in payments, each with a named owner and a retraining schedule. Before that, at Brightline Data, I rebuilt the feature pipeline three forecasting models depended on and cut the overnight run from six hours to under one.
I work best with teams that have shipped a model and are now wondering why it is getting worse…
- FoldThe first sentence is a point of view only this person would write.
- MovedBoth numbers come forward. Nothing new was invented; the roles already on the profile supplied it all.
Fictional example.
How to write a LinkedIn About section
Six steps, starting from what is already on your profile
- 01
Collect the facts before writing a word
From your roles, education, certifications and recommendations: every number, every named outcome, every line someone else wrote about you. Usually five to eight items.
- 02
Pick the one idea the rest supports
Look at the list and ask what connects it, for the reader you have in mind. That sentence is your opening: who you are for a hiring reader, the problem you solve for a client, the view you hold for someone deciding whether to follow you.
- 03
Write the opening lines and stop
Read them alone, logged out, on a phone. If a stranger could not say what you do and why it matters, rewrite them before touching anything else.
- 04
Place the two strongest facts in paragraph two
One sentence each, with the number in it. Name the company if it helps; skip it if the outcome speaks for itself.
- 05
Describe the situation you are best in
Not your values. The kind of team, problem or moment where you do your best work. It will put some readers off, which is the point.
- 06
End with one line for your chosen reader
A subject you are happy to be approached about, what a first step looks like, or where your work can be seen. Then match the headline and the skills you lead with to what you just wrote.
What the About rewrite does
What the report does with your About, and what it leaves to you.
- VoiceWritten in your voice, in the first person, ready to paste.
- EvidenceBuilt only from facts on your profile. Where the evidence is thin, it writes less rather than inventing, and asks you where only you can answer.
- KeepIf your About already works, the report says so instead of rewriting it.
- EndingNotes when your About ends without asking the reader to do anything, and leaves the choice of close to you.
- AccessNo LinkedIn access required. Nothing is posted; you paste the rewrite yourself.
About section FAQ
Questions about the LinkedIn About section and summary
What should I write in my LinkedIn About section?
Four things: what you do and for whom, in a sentence only you could write; the one or two facts that prove it; how you work or what you believe about the work; and what you want to happen next. Most of this already exists on your profile, and the optimizer builds the rewrite from it.
How long should a LinkedIn About section be?
The limit is 2,600 characters, and strong ones are usually far shorter. Length matters much less than the first few lines, about 300 characters, which are all a reader sees before "see more".
Should the LinkedIn About section be in first or third person?
First person. Third person reads as a press release and hides who wrote it. "I build" beats "Marisol builds".
How is this different from an About written from a form or a prompt?
A form or a prompt only knows what you type into it. LinkedCheck also uses AI to write, but it reads your actual profile and writes the About for your goal using only facts already on the page. A claim your profile cannot back is left out rather than written in, so thin evidence makes a shorter About, not an invented one.
Should I include keywords in my About section?
Yes, in sentences. The About is the longest text field on your profile, so the terms from your headline should reappear here, each next to the evidence for it. A comma-separated keyword block at the end reads as spam to people.
Should my About end with a call to action?
Usually, where it follows from what you have just said: one line saying what you would like a reader to do, which depends on your goal. The report notes when your About ends without one, suggests the kinds of close that fit, and leaves the choice to you. How to reach you is optional here; many people keep it in the Contact Info panel instead.
Do you need my LinkedIn login to rewrite my About?
No. The optimizer reads the public version of your profile from the link you paste. You copy the rewrite and paste it yourself; nothing is posted or changed by LinkedCheck.
The About rewrite is part of every paid report.
