How to identify the keywords in a job description

Which words in a posting actually matter, how to tell a requirement from decoration, and how to use them without keyword stuffing.

Not every noun in a posting is a keyword. The useful ones name skills, tools, domains or responsibilities that the employer will search for or ask about.

Where the real requirements live

Look first at the job title, then at the first three bullet points of the responsibilities, then at anything marked essential or required. Repetition is a strong signal: a term that appears in the title and again in the requirements is central to the role.

Separating requirements from decoration

  • Requirement: a named tool, method, domain, qualification or measurable scope.
  • Decoration: culture language, benefits, and mission statements.
  • Ambiguous: soft skills — keep them, but attach them to evidence.

Using keywords without stuffing

Put each term where it is true: in the role where you used the tool, in the skills line if you genuinely have it, in the cover letter if you can explain it. A term that appears nowhere in your experience should not appear in your skills list.
