LinkedIn lets you list up to 50 skills and pin a handful to the top of the section, and recruiters filter searches by them — which makes skills a database field, not a vanity list. Fill most of the 50 with the concrete tools and competencies of your target role, pin the ones that define you, and tag each skill to the positions where you used it.
When a recruiter sources candidates, skills are one of the filters they can apply directly — alongside title, location, and industry. Your skills list therefore determines a set of searches you can appear in at all. An engineer who lists 'Problem Solving' and 'Teamwork' but not 'Kubernetes' and 'Terraform' has opted out of exactly the searches that pay.
The practical rule: fill the list with nouns a recruiter would type. Tools, languages, frameworks, methodologies, certifiable competencies, domain names. Soft skills can occupy a few slots — some recruiters do search 'stakeholder management' — but they should never crowd out the hard, specific, filterable terms. With 50 slots available, you rarely need to choose; you need to bother.
LinkedIn displays a small number of skills — your pinned top skills — before the 'show all' expansion, so pin the ones that define your target role, not necessarily your current one. If you are a data analyst aiming at data engineering, pin the engineering stack you can defend, because the pinned set is what most visitors ever see.
Tag skills to specific experience entries and education. A skill attached to three dated roles reads as a track record; the same skill floating unattached reads as a claim. LinkedIn surfaces these associations on the profile, and they make your history self-verifying in a way no adjective can. When you add a new position, tag its skills immediately.
Endorsements — connections vouching for a skill with one click — are weak signal individually, but a skill with dozens of endorsements from people who actually worked with you does carry some weight with human reviewers. Do not chase endorsements; do accept and reciprocate honest ones. What actually damages you is listing skills you cannot survive an interview question about — the list is a menu of things you have invited people to probe.
Prune annually. Remove skills from a decade ago that you no longer want to be hired for; their presence drags your profile into the wrong searches and dilutes the pinned story. Your skills list should describe the professional you are becoming, not the complete archaeology of everything you have ever touched.
Up to 50. Use most of them — each concrete skill is another recruiter filter you can match. Prioritize the specific tools and competencies of the role you want next, and keep generic soft skills to a small minority of the list.
Only mildly, and only to human readers. There is no evidence endorsement counts drive search ranking, but a skill endorsed by many actual colleagues reads as corroborated. Treat endorsements as a small credibility bonus, not a goal.
The ones that define the job you are targeting — the terms a recruiter for that role would filter by. Pinned skills are what visitors see without expanding the section, so they should tell your forward-looking story, not your historical one.
