Most LinkedIn summaries read like a job description written about someone you've never met. "Results-driven professional with 10+ years of experience driving synergistic outcomes across cross-functional teams." Nobody wrote that. It just happened.

Your LinkedIn summary — officially called the "About" section — is the first place a recruiter goes after your headline catches their eye. It's the one section where you have room to actually sound like a human being, make a case for why someone should reach out, and surface the keywords that make you findable in LinkedIn's search algorithm. Most people waste all three opportunities. Here's how not to.

What your LinkedIn summary actually does

The About section does three distinct things that no other part of your profile can. First, it surfaces keywords that LinkedIn's search algorithm uses to rank your profile in recruiter searches — so what you write here directly affects how often you appear. Second, it's the only section where you can write in first person and actually sound like yourself, which builds the kind of trust that gets someone to press the "Message" button. Third, it lets you make a case that your headline can't fit: why you do what you do, what you're best at, and what kind of opportunity you're looking for.

The four components of a LinkedIn summary that works

1. The hook — first two lines (always visible before "see more")

   LinkedIn collapses your summary to roughly the first two lines on mobile and desktop. Everything after that is hidden behind a "see more" tap. This means your opening two sentences carry disproportionate weight: they determine whether anyone reads the rest. Lead with your strongest credential, your clearest value statement, or a specific achievement — not a generic role description.

   Opening line rewrites

   I am a results-driven marketing professional with over 8 years of experience in the industry, passionate about creating impactful campaigns.

   I help B2B SaaS companies reduce their cost-per-lead — my campaigns at two Series B startups averaged 40% below industry benchmarks.

   Experienced software engineer looking for new opportunities in the tech industry.

   I build backend systems that don't fall over when things get interesting. Currently a senior engineer at Stripe; previously scaled infrastructure for 10M+ users at two fintech startups.

2. Your core value — what you do and who you do it for

   After the hook, use 2–4 sentences to describe your area of expertise, the type of organisations or problems you work with, and the level at which you operate. This is where you add the context a job title alone can't give: domain specificity, scale, and the kind of work you're actually known for. Write it in first person — "I" is fine, and it's warmer than the third-person bio approach most people copy from their own resumes.

3. Two or three headline achievements with numbers

   The middle section of a strong LinkedIn summary includes a short, scannable list of your best evidence. Three bullet points, each with a number, tell a recruiter more than three paragraphs of prose. Keep them tight — one line each. Led a $4M product launch. Reduced customer churn by 22% in 12 months. Grew a team from 4 to 28 engineers. This section is what gets screenshotted and shared in recruiting slack channels.

4. A clear signal of what you're looking for (or open to)

   The last 1–2 sentences should tell a recruiter what to do next. Are you actively looking? Open to the right opportunity? Specifically interested in certain industries, roles, or company stages? Be direct — "I'm currently exploring senior product roles at Series B–D startups in fintech or healthtech" is far more useful than "I'm always interested in connecting." It saves everyone's time and attracts more relevant outreach.

How LinkedIn search actually works — and what to put in your summary

LinkedIn's search algorithm indexes the text in your About section and ranks profiles by relevance for recruiter keyword searches. That means the words you use in your summary directly affect how often you appear when a recruiter searches for candidates in your field.

LinkedIn publishes a list of its most overused profile buzzwords annually — the list above represents a consistent core of terms that appear so frequently they've become invisible to recruiters. They're not keywords; they're filler.

What kills LinkedIn summary performance

• ⚠️

  Leaving it blank. An empty About section tells a recruiter nothing and costs you search ranking. Even 3–4 lines is better than nothing, and nothing is the current state for more profiles than you'd expect.

• ⚠️

  Writing in third person. "John is an experienced leader who…" reads like a press release and signals the summary was written by someone else, or pasted from a bio. First person is warmer, more credible, and more readable.

• ⚠️

  Making the hook generic. The first two lines are all most people read. If yours opens with "I am a results-driven professional…" you've already lost the recruiter who has forty more profiles to look at.

• ⚠️

  No call to action at the end. The most common missed opportunity on LinkedIn. Tell people what you're open to and what the next step is. Recruiters won't guess — they'll move to the next candidate.

• ⚠️

  Copying your resume bullet points directly. Your LinkedIn summary is not a list of job duties. It's a pitch. It should sound different to your resume — more personal, more direct, and more forward-looking.
