How to Do Keyword Research for LinkedIn

Job posting analysis is the most reliable keyword research method for LinkedIn. Collect 10–15 job postings for roles you want to be found for. Copy them into a document and highlight every repeated term: job titles, required skills, tools, certifications, and industry terms. Words that appear in 80% or more of listings are your primary keywords. Words in 40–79% are secondary keywords. This method directly maps your keyword strategy to what hiring teams are actually searching for.

Competitor analysis: find 5–10 LinkedIn profiles of people who hold the roles you are targeting (or who rank well for your target keywords). Study what keywords appear in their headlines, about sections, and experience descriptions. Note which skills they list. This reverse-engineers what is currently working for search ranking in your niche. Do not copy their profiles — extract the keyword patterns and adapt them to your own genuine experience and language.

LinkedIn search suggestions: type the first two words of your target keyword into LinkedIn's search bar and note the autocomplete suggestions. These suggestions are generated from actual search behaviour — they reflect what real users (recruiters, hiring managers, peers) are typing. Each suggestion is a validated keyword you should consider incorporating into your profile. Repeat this process for 5–10 keyword starting points to build a comprehensive keyword list.

LinkedIn Skills Insights: view the Skills section of profiles in your target role and note which skills appear most frequently. LinkedIn also shows trending skills for industries and job functions on its talent reports. Cross-reference these with your own capabilities — add every skill you genuinely possess that appears on these lists. The skills section is a direct ranking signal: profiles with endorsed skills matching a recruiter's search term rank significantly higher.

Free keyword research tools: LinkedIn's own search autocomplete (free, unlimited), Google Trends (compare keyword popularity over time), Google Keyword Planner (search volume data, requires a Google Ads account but does not require spending), and our LinkedIn Profile Keyword Analyzer (scans your profile and compares it against target keywords). Use these tools to validate your keyword list and identify gaps where your profile is missing terms that recruiters are actively searching for.
