LinkedIn is the most important professional networking platform in the UK. With over 45 million UK members [1], it's where recruiters source candidates, hiring managers research applicants, and professionals build their industry presence.
Yet most LinkedIn profiles are under-optimised — missing keywords that recruiters search for, using weak headlines, and failing to tell a compelling professional story. Here's how to fix that.
1. Write a headline that works for search
Your headline is the most important line on your profile. It appears in search results, connection requests, and comments you leave on posts. The default — your current job title and company — is a missed opportunity.
A strong headline should include:
- Your role or professional identity
- 1-2 key skills or specialisms
- The industry or sector you work in
Weak: "Marketing Manager at Acme Ltd"
Strong: "Marketing Manager | B2B SaaS | Content Strategy & Demand Generation"
The strong version tells recruiters exactly what you do and includes keywords they're likely searching for. LinkedIn's search algorithm weighs headline text heavily, so the right keywords here directly affect your visibility.
2. Craft a compelling About section
Your About section (formerly the Summary) is your chance to tell your professional story in your own words. Most people leave it blank or write a single paragraph — this is a significant missed opportunity.
Structure your About section like this:
- Opening hook (2-3 lines): What you do and what drives you professionally. Write in first person — it's more engaging than third person.
- Key achievements (3-5 bullets): Your most impressive accomplishments with numbers. These demonstrate your track record.
- What you're looking for (1-2 lines): If you're actively job searching, state it clearly. If you're open to opportunities, mention the types of roles that interest you.
- Core skills (keyword list): End with a list of your key skills and specialisms. This helps with LinkedIn's search algorithm.
Keep the tone professional but personable. Recruiters read hundreds of profiles — personality helps you stand out.
3. Optimise your experience section
Don't just list your job titles and responsibilities. Each role should demonstrate impact, using the same achievement-focused approach you'd use on your CV:
- Start each bullet with an action verb
- Include specific numbers and outcomes
- Focus on achievements, not duties
- Use industry-standard terminology that recruiters search for
Weak: "Responsible for managing the sales team and hitting targets."
Strong: "Led a team of 8 sales executives, consistently exceeding quarterly targets by 15-20%. Implemented a new CRM workflow that increased pipeline visibility and reduced deal cycle time by 25%."
4. Use the right keywords throughout
Recruiters find candidates by searching for specific skills, job titles, and qualifications. LinkedIn's algorithm matches these searches against your profile content — particularly your headline, About section, experience descriptions, and skills list.
To identify the right keywords:
- Look at job descriptions for roles you're targeting — what terms appear repeatedly?
- Check profiles of people currently in your target role — what keywords do they use?
- Include both full terms and abbreviations (e.g., "Project Management Professional (PMP)")
- Add relevant industry-specific terms and methodologies
5. Maximise your skills section
LinkedIn allows up to 100 skills on your profile. You should use as many as are relevant, prioritising the most relevant ones [3]. Skills serve two purposes:
- Search visibility: Recruiters filter candidates by skills, so having the right ones listed increases your chances of appearing in search results.
- Endorsements: Skills with endorsements from colleagues add social proof to your profile.
Pin your top 3 skills — these should be the competencies most central to your target role.
6. Get a professional profile photo
Profiles with photos receive significantly more views than those without [2]. Your photo should be:
- A recent, clear headshot with good lighting
- Professional but approachable — a slight smile works well
- Against a plain or uncluttered background
- Just your face and shoulders — not a full-body shot or group photo
You don't need a professional photographer. A smartphone photo in natural light, cropped to a headshot, works perfectly well.
7. Customise your LinkedIn URL
LinkedIn assigns a default URL with random numbers (e.g., linkedin.com/in/john-smith-7a8b9c). Customise this to your name or professional brand (e.g., linkedin.com/in/johnsmith). This looks more professional on your CV and in email signatures.
8. Use the "Open to Work" feature strategically
LinkedIn's "Open to Work" feature lets recruiters know you're available. You have two options:
- Visible to recruiters only: A subtle signal that doesn't show a green banner on your profile. Best if you're employed and exploring quietly.
- Visible to all: Adds the green "Open to Work" banner. Effective for active job seekers, but be aware your current employer may see it.
When setting preferences, be specific about the job titles, locations, and work arrangements (remote, hybrid, on-site) you're targeting.
9. Engage with content
An active LinkedIn profile is more visible than a passive one. You don't need to post daily, but regular engagement helps:
- Comment thoughtfully on posts in your industry — this puts your profile in front of new connections
- Share articles or insights relevant to your field
- Congratulate connections on new roles or achievements
- Follow companies you're interested in working for
Automate your LinkedIn optimisation
Optimising your LinkedIn profile manually can be time-consuming, especially if you're not sure which keywords to target or how to restructure your experience for maximum impact.
LandTheRole's LinkedIn optimiser analyses your current profile and generates improved versions of your headline, About section, and experience bullets — tailored to the types of roles you're targeting and optimised for recruiter search visibility.
