How LinkedIn Search Works
LinkedIn uses a computer algorithm that looks at profiles to see how well they match what recruiters are searching for.
It checks:
- Your headline
- Skills
- Job titles
- Experience

Profiles are ranked based on how they match what recruiters are searching for.
👉LinkedIn says that search results depend on keywords and relevance.
Key Ranking Factors:

New systems even use computer tools to understand what recruiters mean not the exact words.
👉This means that even if recruiters do not type keywords LinkedIn still tries to match profiles based on meaning.
