LinkedIn keyword optimisation is the practice of placing the words your audience actually searches for into specific, indexed fields on your LinkedIn profile or company page. Done well, it triples your visibility in LinkedIn search and doubles your appearance in InMail and recommendation engines. Done badly, it makes you sound like a SEO spam page.
LinkedIn's internal search is the most underrated channel on the platform. Hiring managers, customers, and journalists all use it. Here's what to optimise, where, and how to avoid keyword stuffing.
Best keywords for a LinkedIn profile
Pick keywords across three categories:
Job-title keywords. Exact titles people search to find someone like you: "Product Manager," "B2B SaaS Marketer," "UX Designer."
Skill keywords. Specific skills relevant to your role: "Figma," "SQL," "GTM strategy," "demand generation."
Industry / niche keywords. Where you work or want to work: "fintech," "B2B SaaS," "developer tools," "creator economy."
Aim for 8-12 total keywords. Below 8 and your profile is too generic; above 12 and the keywords dilute each other.
Where to actually place keywords on LinkedIn
LinkedIn indexes six fields. Place keywords in priority order:
Headline. 220 characters under your name. Highest-weighted field. Lead with your primary job title and 2-3 skill keywords. Format: "Title | Skill • Skill • Skill | Industry."
About section. 2,600 characters. Second-highest weight. Use the first 250 characters wisely — they show in search previews.
Experience descriptions. Each job description. Weave keywords naturally into outcome-focused bullets.
Skills section. Up to 50. Pin your top 3 to the top.
Featured section. Posts, articles, links you pin. Use descriptive titles.
Current job title. If you control it, optimise. Some employers lock title formatting.
The Headline alone drives 60-70% of search ranking. If you only optimise one field, optimise that one.
LinkedIn headline formula that works
The format that consistently ranks:
[Job Title] at [Company] | I help [audience] [outcome] | [skill keyword] • [skill keyword] • [skill keyword]
Real examples:
"Head of Growth at SaaS Studio | I help B2B founders ship demand gen that compounds | SEO • Paid acquisition • Retention"
"Senior UX Designer | I help fintech teams build trust-driven product experiences | Figma • Design systems • Research"
"Founder, So-me Studio | I help small teams ship 10x social media output | Scheduler • AI captions • Bio links"
The "I help X do Y" structure does double duty — it signals to humans what you do and packs three searchable keywords for the algorithm.
LinkedIn SEO strategies that drive views
Add a custom URL slug. Settings → Edit public profile → Custom URL. Use yourname or yourcompany. LinkedIn URLs are indexed by Google, and a clean URL ranks higher.
Get keyword-rich endorsements. Top-pinned skills receive endorsements that count as search-relevance signal. Ask 5 colleagues to endorse your top 3 skills.
Publish posts using your target keywords. Posting about "B2B SaaS demand generation" repeatedly signals to LinkedIn's algorithm that you're an authority on it.
Use LinkedIn Articles (long-form). Published Articles are indexed both inside LinkedIn and on Google. Pick keyword-rich titles.
Optimise your media files' alt text. When uploading images to your profile, name files with keywords ("growth-marketing-portfolio.jpg" beats "IMG_1234.jpg").
Keyword optimisation for company pages
Pages have similar fields, prioritise:
Page tagline. 120 characters. Match your value prop + target customer.
About section. 2,000 characters indexed for search.
Specialty tags. Up to 20 tags. Pick specific over generic ("B2B SaaS demand generation" beats "marketing").
Job postings. Indexed separately. Include role-specific keywords in descriptions.
Why keyword stuffing fails
LinkedIn detects unnatural repetition. Three signs your profile is stuffed:
Your headline reads as a comma-separated list with no verbs
Your About section uses the same noun three times in two sentences
Your Skills section has 50 listed but only 3 endorsements total
The algorithm de-prioritises stuffed profiles in search. Worse, real humans bounce — keyword-stuffed profiles read like CVs no one wanted.
How to find your audience's actual search terms
LinkedIn job search. Search for the job title you want. Note the keywords in the top-ranked job descriptions.
Competitor profiles. Look at the LinkedIn profiles of people in your target role. Note their headlines and skills sections.
Recruiter language. If you're job-hunting, look at the language recruiters use in InMails. That's their search vocabulary.
Search analytics. LinkedIn Premium shows you the keywords users typed to find your profile. Worth $40/mo if you take outreach seriously.
Using keywords in LinkedIn posts
The first 200 characters of a LinkedIn post are weighted highest for in-platform search. Three principles:
Lead with the keyword or topic in the first line
Use 3-5 relevant hashtags (LinkedIn rewards them, but caps at ~5 before diminishing returns)
Reference your topic 3-4 times naturally throughout the post
FAQ
What are the best keywords for a LinkedIn profile?
A mix of job-title keywords, skill keywords, and industry/niche keywords. 8-12 total, placed in priority order: headline, about, experience, skills.
How long should my LinkedIn headline be?
220 characters max. Use them — most users leave 100+ characters on the table. The headline drives 60-70% of search ranking.
Does keyword stuffing work on LinkedIn?
No. LinkedIn de-prioritises stuffed profiles in search results. Worse, humans bounce.
How many skills should I list on LinkedIn?
50 is the max, but pin your top 3 for visibility. Aim to have 5+ endorsements on each of those top 3.
Should I use hashtags in LinkedIn posts?
Yes. 3-5 relevant hashtags per post. More than 5 and returns diminish.
