Find the words your resume is missing.

Paste your resume and the job description into the checker at the top of this page. Our free ATS resume checker compares the two, gives you a match score, and lists the keywords you’re missing—so you can fix gaps before you apply.

How to check your resume for ATS

1. Paste the job description. Copy the full posting—duties, requirements, and preferred skills. The more complete the text, the clearer your keyword match will be.
2. Paste your resume. Use plain text from your resume (or paste from a Word/Google Doc). The ATS resume checker reads the words on the page, the same way screening software does.
3. Review your score and missing keywords. You’ll get a match score plus a list of terms from the job that don’t appear in your resume. Add the ones that truly fit your experience, then run the check again.

Paste the posting and your resume, check the gaps, fix what is honest.

That’s the whole loop: paste, check, fix, recheck. No account required.

What an ATS resume checker actually looks at

Applicant tracking systems don’t “read” your career story the way a recruiter does. They parse text, map it to fields, and score how well you line up with the posting. Here’s what matters most when you run a check.

Keyword matching

This is the core of resume optimization for ATS. The tool compares words and phrases in the job description against your resume. If the posting asks for “SQL,” “stakeholder management,” or “Salesforce,” and those terms never appear in your document, your match drops—even if you’ve done the work under different wording.

Terms in the overlap already match; the gaps on the left are what the checker lists as missing.

Formatting that machines can parse

Complex tables, text boxes, headers/footers, and multi-column layouts can scramble how text is extracted. Clean section labels, standard fonts, and a simple top-to-bottom layout help the checker (and real ATS tools) see your content in order.

Clear resume sections

Standard headings—Experience, Education, Skills, Summary—help screening software place your information correctly. Unusual section names or long blocks of unbroken text make it harder for both the ATS and our checker to map your background to the job.

Job-title alignment

If the posting is for “Marketing Manager” and your recent titles are unrelated or vague, keyword matching alone won’t fully close the gap. Align titles and responsibility language with the role you’re targeting when it’s honest and accurate.

Our free tool focuses on ATS keyword matching: you get a score and a missing-keyword list. Want a rating-style read of how you line up with the role? Try rate my resume. Prefer to start from an AI resume checker? Open that page and run the check against the same posting.

ATS score explained — what a good score looks like

Your ATS score is a snapshot of how closely your resume’s wording lines up with that specific job description. It is not a hiring decision and it is not a guarantee you’ll get an interview. It’s a practical signal: are the right terms present, and where are the gaps?

A strong score usually means your resume already uses many of the same skills, tools, and responsibility phrases as the posting. You may still tweak a few missing keywords that match real experience.

A mid-range score often means you’re close but underusing the employer’s language. Scan the missing list. Add terms you can support with examples from your work—don’t paste buzzwords you can’t back up.

A low score usually means a mismatch of language or role focus. Either rewrite toward this posting’s requirements or confirm you’re applying to the right level and function.

Use the score as a checklist, not a grade. Recheck after each edit. Small, honest keyword updates often move the needle more than a full rewrite.

Why resumes get rejected before a human reads them

Many applications never reach a recruiter’s desk. Screening software filters for parseable text and relevance to the posting. When keywords are missing, sections are hard to extract, or the resume doesn’t align with the job’s stated needs, the file can be ranked low or set aside before anyone reads your story.

That’s why an ATS resume checker belongs at the end of your writing process—not as an afterthought. You’ve already built the content; this step confirms the job’s language is reflected where it should be. Run the check with the exact posting you’re applying to, fix gaps you can honestly claim, and submit with fewer blind spots.

Anxiety around “Will this pass ATS?” is normal. The fix is concrete: match the job’s vocabulary to your real experience, keep formatting simple, and verify before you hit Apply.

How to build your ATS keyword list

A strong ATS keyword list comes from the job description itself, sorted into three tiers so you edit with intent instead of stuffing every noun you see.

Must-have terms are the job title and the hard skills that show up in the requirements—tools, platforms, methods, and credentials the employer treats as non-negotiable. If the posting repeats “project manager,” “Jira,” or “stakeholder management” in the requirements block, those belong on your must-have list and should appear where your experience can support them.

Nice-to-have terms are industry vocabulary that appears once or twice: preferred frameworks, secondary tools, or soft-skill phrases that round out the posting. Add them when they are true and natural; they help coverage without pretending every rare word is a dealbreaker.

Terms you should not force in are tools or certifications you genuinely do not have. Inventing a badge or a stack you never used will raise a match score for a moment and collapse in an interview. Leave those gaps visible and honest.

When you weave a must-have in, put it inside a real bullet—not at the end of a dump. Natural: “Led weekly sprint planning in Jira for a six-person delivery team.” Stuffed: “Managed projects. Skills: Jira, Agile, Scrum, Kanban, Jira.” After you draft the list, run this free checker, then compare notes with our AI resume checker or rate my resume if you want another pass on the same posting.
