See exactly which keywords from the job description are missing from your resume — the same terms ATS software uses to rank and filter candidates.
Last updated August 11, 2026
Quick Answer
A resume keyword scanner compares the vocabulary of a job description against your resume and lists the terms you are missing. Because ATS systems rank candidates by keyword overlap, those missing terms are often the difference between a shortlist and a rejection. Our scanner shows missing skills, tools, and qualifications with placement suggestions.
The scanner extracts skills, technologies, tools, certifications, and requirement phrases from the job description, then checks which ones appear in your resume — in context, not just as loose strings.
Summarizing categories instead of naming instances. Job descriptions almost always name specific tools — 'AWS Lambda, S3, CloudFormation' — while resumes say 'cloud experience.' ATS systems match exact terms. If the JD says 'PostgreSQL' and your resume says 'SQL databases,' the match is often missed.
| Job description says | Weak resume says | Strong resume says |
|---|---|---|
| PostgreSQL, Redis, Kafka | Databases | PostgreSQL, Redis, Kafka |
| Agile/Scrum | Fast-paced environment | Scrum teams, Agile sprints |
| Google Analytics 4 | Analytics | Google Analytics 4 (GA4) |
| SOC 2 compliance | Security experience | SOC 2 audit readiness |
Weak vs. strong keyword placement
Rule
Mirror the job description's exact terminology wherever it is truthful. Never add keywords you cannot back up in an interview.
You do not need every keyword — you need the ones tied to the role's hard requirements. Missing an 'AWS' mention when the JD lists it under Required is costly. Missing a 'nice-to-have' like a specific dashboarding tool matters less. Prioritize Required skills first, then add preferred skills you genuinely have.
| Match rate | What it means for your application |
|---|---|
| 90–100% | Outstanding — your resume mirrors the job description's core vocabulary. Apply with confidence. |
| 70–89% | Strong — close the few remaining gaps in your summary and skills section before applying. |
| 50–69% | Average — most candidates land here. Tailor your top bullets to the exact JD language. |
| Below 50% | Weak — the ATS is likely ranking you out. Rework the resume around the job description. |
What your keyword match rate means
Understanding how applicant tracking systems match keywords explains why the scanner is built the way it is.
Most ATS platforms do not read resumes like recruiters do. They parse the text into fields, then compare the vocabulary against the job description using exact-match terms, synonym groups, and phrase-based requirements. A resume that says 'customer relationship management' may be missed when the job description asks for 'CRM' — which is why the scanner checks both the full phrase and the acronym.
One word can be the difference
Acronyms like SQL, AWS, or KPI are extracted separately from the full phrases they abbreviate. If the job description says 'SQL' but your resume only says 'structured query language,' the scanner flags a miss — add the acronym in your skills section to close it.
Skills, tools, technologies, certifications, and requirement phrases that appear in the job description. ATS systems use these to rank candidates against the role.
