How to write a LinkedIn About section that works for you while you sleep

The About section is the most read part of a LinkedIn profile after the headline, and also the worst written. Most are variations of the same template: three generic mission sentences, a paragraph of vague verbs ("I help", "I support") and a close inviting people to connect. That About section does not work for you. It takes up space.

An About section that does work for you is a stable piece that, while you sleep, filters who messages you, who does not and with what context. It gives a stranger enough information to decide whether a call is worth it, without you having to intervene. This guide explains how to write it for that job, and how to avoid the templates that leave it inert.

What an About section has to do to work for you

The About section is not a biography, a CV or a manifesto. It is a text a stranger reads for thirty to ninety seconds before deciding whether to message you. Its job is to get the right person messaging you with the right context, and to let the wrong one realise before messaging that this is not a fit, so they do not waste your time.

That means four concrete things: making clear what you do (not what you are), who you do it for (the profile of your typical client or counterpart), what distinguishes how you do it (not what most people promise, what you genuinely hold to), and how to get in touch if the reader fits. Everything else is filler.

When those four elements are there and done well, the About section filters on its own. The connection messages you receive rise in quality, the calls you accept are more productive, and the ones you would not accept never reach you because the sender saw it was not a fit.

The four block structure that works in 2026

The structure that holds up a useful About section is the same for almost every professional profile, even when the content varies. Four short blocks, between 350 and 600 words in total, written in the first person without fear.

  • Block 1 (2 to 3 sentences): what you do in one concrete sentence, naming the real craft and the context you operate in. No "passionate about", "I help", "positive impact".
  • Block 2 (4 to 6 sentences): who you work for or usually collaborate with. Typical client, industry, project size, type of engagement. The more specific, the more it filters.
  • Block 3 (5 to 8 sentences): what distinguishes how you work. Not what anyone in your field offers: what you genuinely believe and practise, with a concrete example or principle only you would state.
  • Block 4 (2 to 3 sentences): how to get in touch, what context helps to include in a first message and which messages you will not answer. This is the final filter.

Why the first sentence decides whether they read the other three blocks

LinkedIn cuts the About section after roughly 220 characters and shows a "...see more" the reader has to tap. That first line decides whether they open or close. A line like "Passionate about digital marketing with over ten years of experience" loses 90% of readers right there.

A first line that works does one of three things: it names the craft precisely and your own angle in the same sentence ("I design operations systems for consultancies under twenty people"), it makes a non obvious observation about the industry ("Most Spanish SMEs do not have a lead problem: they have a time-to-answer-them problem"), or it opens with a tiny anecdote that anchors what follows ("Two years ago I left a big agency because I realised we were selling the same carousel to thirty different clients").

Any of the three works better than the template if it contains concrete information only you could have written. The quick test: if you could have copied that sentence from another profile without changing a word, you do not have it yet.

What to cut without mercy from your current About section

The traits that sink an About section are the same ones that sink any post: vague promises, self satisfied adjectives and no nameable details. These are the four that appear most often and are worth striking out before rewriting anything.

  • Vague verbs ("I help", "I support", "I drive impact in", "I empower"): replace them with the real verb for what you do ("I design", "I audit", "I negotiate", "I test").
  • Self satisfied adjectives ("passionate", "resilient", "innovative", "results-oriented"): out. Nobody reading them believes you, and whoever does believe you was not going to message you because of that.
  • References to years of experience with no context ("over X years in the industry"): replace them with the number of concrete projects, specific clients or figures only you can cite.
  • Generic closes ("if you think I can help, do not hesitate to message me"): replace them with concrete instructions on how to message you to maximise the chance of a reply.

LinkedIn's internal SEO almost nobody exploits well

LinkedIn's internal search indexes the About section heavily to position profiles for recruiters and B2B buyers. That does not mean shoehorning keywords in (LinkedIn has penalised keyword stuffing since 2024), it means making sure the exact words your audience searches with appear naturally.

A physiotherapist specialising in running probably writes "I work in sports recovery" when their audience searches "sports physio Madrid" or "runner injuries". An operations consultant might write "I optimise processes" when their audience searches "lean manufacturing SMEs" or "operations review". The difference shows up in search appearances.

The exercise that helps: write down the five searches you would run if you needed to hire someone like you. Check those exact phrases appear in your About section at least once, in context and without sounding forced. If one is missing, rewrite the relevant sentence to include it naturally.

How often to update it (less than you think)

A well written About section holds up for eighteen to thirty six months without significant changes. You revise it when you change role, industry, client type or how you invoice. Not when you close a project, not when the year changes, not when somebody reads it.

The temptation to update it every quarter is a signal that the original text was too tied to a passing context. An About section that ages well is written in a sustainable present: it describes what you do by default, not what you did last quarter. One-off achievements live in the experience section and in your feed posts, not here.

The only steady review worth scheduling is reading it all the way through every six months, out loud, and removing any sentence you would no longer stand behind on a call. That exercise costs ten minutes and stops the profile from going stale without you noticing.

An About section that works for you is a filter, not an advert

Writing a good About section is not an exercise in personal marketing, it is an exercise in operational honesty. You say what you do, who for, how, and what you expect from whoever messages you. The natural consequence is that fewer people message you and more of the people who do are worth it.

In 2026, with LinkedIn's feed full of profiles that sound the same, an About section with judgement of its own is one of the highest returning assets there is. It needs no maintenance, generates no ongoing work, and filters without you intervening. It works for you while you sleep.

Frequently asked questions

How long should the About section be?

Between 350 and 600 words. Below that there is usually not enough context to filter; above it the reader does not reach the end. Very technical or very senior profiles can stretch to 800 words if block 3 (what distinguishes you) justifies it with concrete examples.

Should I write in the first or third person?

First person, unless you represent a corporate brand from a company profile. The third person ("Marta is a consultant with...") sounds like a press release and lowers the connection with the reader. First person is LinkedIn's standard convention in 2026.

Can I use AI to write my About section?

For a first structural draft, yes. For the final text, not directly: About sections generated with no human editing all fall into the centroid template and cancel out the filtering function. Write blocks 1 and 3 yourself (the first line and the "what distinguishes you"), and use AI only to polish blocks 2 and 4.

Should I mention my current employer in the About section?

Mention the role and the type of work, not necessarily the company name (which already appears in the experience section). If you are self employed, the professional name is worth mentioning. If you work at a very well known company whose name adds useful context, include it. If it adds nothing, save the space.

Does the About section change much between a sales profile and a job hunting one?

The skeleton is the same, block 4 changes. On a sales profile, describe how to get in touch and with what context. On a job hunting one, describe what role you are after, what kind of company interests you and in what format (remote, on site, employed, freelance). The other blocks barely move.
