5 Rules for a LinkedIn Profile HR Actually Likes

How do recruiters actually search for candidates on LinkedIn?

Almost every recruiter uses LinkedIn Recruiter or a similar Boolean search tool. They type a job title, a location, two or three skills, and sometimes a current or past company. The platform then ranks profiles by how well the headline, About section, current job title and skills match those search terms.

This means spending an hour on your LinkedIn profile is one of the highest-impact things you can do during a job search. The five rules below are ranked in order of impact on that ranking.

The five rules

1. Treat your headline like a search result. Your headline is the single most-indexed line on your profile. Use the exact job title you want next, not the one you currently hold, and add one specialism plus one industry. Example: "Senior Marketing Manager, B2B SaaS, lifecycle & retention." Avoid mottos, emojis and "helping people achieve their potential", none of those are searchable.
2. Use a real, recent photo. Plain background, shoulders in frame, neutral expression, eye contact with the camera. No selfies, no group crops, no five-year-old conference badges, no sunglasses. A clear professional photo makes a real difference: profiles with one tend to get noticeably more views than those without.
3. Write the About section in first person. Three short paragraphs: who you help, how you help, and what you're looking for next. Recruiters skim, write in plain, scannable English. Put your most-searched keywords in the first two lines, because that's all that shows before "see more."
4. Lead every job with outcomes, not duties. "Owned the onboarding funnel and lifted activation 18%" beats "Responsible for onboarding flows." Numbers, even rough or rounded ones, double the credibility of every line they appear in. If you can't share a number publicly, share a scope: team size, budget owned, geography covered.
5. Turn on "Open to Work" privately. The discreet recruiter-only signal puts you in front of the people you want to find you, without telling your current employer. Combine it with three target job titles and a realistic location radius, vague preferences get vague matches.

What should I avoid on my LinkedIn profile?

Three things hurt you more than people realise: empty sections (especially Skills and About), buzzword-heavy headlines that don't include a real job title, and dormant activity. You don't need to post weekly, but a profile that hasn't been touched in two years signals to recruiters that you may not be reachable. A single thoughtful comment on an industry post once a month is enough to keep your name circulating.

The bonus rule no one talks about

Edit your profile from a logged-out browser window once a month. Seeing what a recruiter sees (not what you see when logged in) is the quickest way to spot the line that needs a rewrite, the empty section, and the photo that has not aged well.
