ATS Resume Checker

Paste your resume and a job description to get a detailed ATS compatibility score with missing keywords, qualification gaps, and actionable fixes.

Most ATS checkers give you a generic score. OnepageCV scores your resume against a specific job description across 6 weighted categories — so you know exactly where you're weak and how to fix it.

What Is an ATS Resume Checker?

And why "job-specific" is the word that matters.

An ATS resume checker tells you how well your resume will perform against the software companies use to screen applications — the Applicant Tracking System. When you apply online, your resume lands in an ATS first, where recruiters search and rank candidates by keywords and qualifications before a human reads anything. The checker simulates that: it scores how readable your resume is to the parser and how well it matches the role.

The catch most tools miss: real ATS screening is never generic. The employer ranks you against their posting — their keywords, their must-haves. So a resume that scores well on a universal checklist can still score poorly for the specific job you want. That's why OnepageCV scores your resume against a job description you paste, not an abstract rubric — and returns the exact missing keywords, unmatched qualifications and weak bullets for that role. A full explainer lives in our guide to ATS scores.

What's a Good ATS Score?

Measured against the specific job you're applying to.

Score	What it means	What to do
80–100	Strong alignment — your resume carries most of the role's key skills, qualifications and keywords.	Apply. Skim remaining fixes for quick wins.
60–79	Right candidate, wrong words — the substance is there but the posting's language isn't.	Tailor it — most resumes here jump 10–20 points.
40–59	Real gaps — several must-have requirements have no support in your resume.	Add true-but-missing skills; or target closer roles.
Below 40	Misaligned — the role wants a materially different profile.	Usually not worth applying as-is.

80+ is strong and applyable. Don't chase 100 — high-90s scores usually come from keyword stuffing, which both ATS ranking and human recruiters penalise. Aim for an honest high-70s to 80s against the real posting, then apply.

How to Improve Your ATS Score

All honest — none of it means faking experience.

Mirror the job description's exact words for skills you genuinely have — "CI/CD pipelines," not "deployment automation."
Add missing-but-true keywords you forgot to list — a keyword scanner surfaces them instantly.
Use a clean single-column layout with standard headings; drop tables, text boxes, columns and images that break parsing.
Spell out acronyms once — "Search Engine Optimization (SEO)" — to match either search form.
Quantify your bullets and keep it to one clean page.
Tailor per application — the single biggest lever. An AI resume tailor does this against a specific posting in about two minutes.

Frequently Asked Questions

Common questions about ats resume checker.

What is a good ATS score?

80 or above against the specific job you're applying to is strong — your resume carries most of the role's key skills and keywords. 60–79 means your experience fits but your wording doesn't match the posting yet (tailoring fixes this fast). Below 60 signals real gaps. A score only means something measured against a particular job description.

How do I check my ATS score?

Paste your resume and the specific job description above and run the check. You get a job-specific score plus the exact missing keywords, unmatched qualifications and weak bullets — the number comes with a fix list, not just a grade.

Do I need a job description?

Yes — and that's the point. Unlike generic ATS checkers, OnepageCV scores your resume against a specific JD, which is how real ATS screening actually works. The same resume scores differently for different roles.

Do applicant tracking systems auto-reject resumes?

Mostly no — a common myth. Most ATS platforms rank and filter rather than auto-rejecting; a human still decides. But if your resume lacks the keywords a recruiter searches for, you never surface in their results, so poor alignment keeps you invisible anyway.

Does resume formatting affect the score?

Yes. Multi-column layouts, tables, headers/footers, graphics and text boxes can cause the ATS to misread or drop content — lowering your effective score because skills buried in unparseable elements never get counted. A single-column, standard-heading format parses cleanly.

Is a higher ATS score always better?

No. The score measures alignment with a job description, not candidate quality, and can't predict interviews. Chasing a perfect score usually means keyword stuffing, which reads as spam to recruiters. Hit a strong honest number, then apply.

How are the 6 categories weighted?

Keyword Match (40%), Qualification Match (25%), Experience Relevance (15%), ATS Parsability (10%), Impact Quality (5%), Big Tech Quality (5%). Keywords matter most because ATS systems filter on them first.

Can I fix issues directly?

Yes. Each fix includes an Apply button that rewrites the bullet or adds the keyword directly in your resume. You can preview every change before applying.

What ATS systems does this work for?

The checker tests universal ATS best practices — parsable formatting, keyword presence, standard headings, quantified impact — which apply across Greenhouse, Lever, Workday, iCIMS and others.

Is the ATS checker free?

Yes — your first full check (score, missing keywords, gap breakdown) is free, no card required. Pro unlocks unlimited checks for applying to many roles.
