What is a good LinkedIn profile and does it actually matter?

It matters mostly as an inbound channel — recruiters search it constantly, and a good profile means opportunities find you instead of the reverse. That's a meaningfully different value proposition from a resume, and it's why it's worth a few hours. **The parts that actually do work, in order of impact:** 1. **Headline.** The most valuable text on the page. It appears in every search result and message. Don't use your job title alone — use what you do plus your specialism: 'Backend Engineer | Python, distributed systems | Fintech'. This is also what search matching hits. 2. **Keywords throughout.** Recruiters search by skills and technologies. If a term isn't on your profile, you don't appear. Put the real terms in your headline, About section, experience bullets and skills list — using the words the industry actually uses, not internal company jargon. 3. **About section.** Three or four short paragraphs in first person: what you do, what you've built, what you're interested in. Most people leave it blank, which wastes the one place you get to speak in your own voice. Write it like a person, not a press release. 4. **Experience with achievements**, not duties — same rule as a resume, with numbers. 5. **Photo.** A clear, friendly headshot. Profiles with photos get substantially more engagement, and a phone photo against a plain wall is completely fine. 6. **'Open to work' setting**, which can be made visible only to recruiters rather than publicly — worth knowing if you're searching discreetly. **What's overrated**: connection count beyond a few hundred, endorsements (nobody weights them), and elaborate banner graphics. **What's underrated**: posting occasionally about work you're doing. You don't need to be an influencer — a few posts a year about a project, a problem you solved, or something you learned keeps you visible and gives recruiters and hiring managers a sense of you beyond a job title. The bar for 'stands out' is genuinely low because most people never post anything. **Recommendations** from colleagues carry real weight and cost nothing to request. Two or three specific ones from people you worked closely with are worth more than twenty endorsements. **The honest calibration**: for a passive job seeker or someone in a field with recruiter demand, a good profile is one of the highest-return few hours available. For an active search, it supports rather than replaces applying and networking. Either way, a barebones profile is a missed channel rather than a neutral one — because you're findable either way, and the question is only what people find.
