Resume Keyword Checker – Find Missing ATS Keywords

Keyword gaps are one of the biggest reasons resumes underperform in ATS screening. Recruiters and screening systems compare your resume against the job description language. If you miss key terms, your resume can be filtered out even when you're qualified.

ResumeUp shows exact missing keywords (required skills, tools, metric language, soft skills) and gives a score-first preview so you can prioritize what to fix first without stuffing.

What keywords does ATS look for?

ATS keyword matching isn't only about "skills." Most job descriptions include: required skills, tools, and metrics language (like "A/B testing", "LTV", "SQL", "revenue growth"). Missing these reduces visibility quickly.

Example missing keywords we often find

  • • Cross-functional collaboration
  • • Stakeholder management
  • • Experimentation / A/B testing
  • • Revenue tooling / funnel analytics
  • • SQL / dashboards / reporting
