How the Free ATS Resume Checker Works

Upload your resume to see how applicant tracking systems read your formatting, keywords, and section structure—then fix issues before recruiters ever see your application.

What is an ATS (Applicant Tracking System)?

When you apply online, your resume usually enters an ATS first—not a recruiter's inbox. Systems like Workday, Greenhouse, Lever, and Taleo extract your contact details, work history, skills, and education into structured fields. Recruiters then search and filter candidates by job title, keywords, and location. If your layout breaks parsing, entire sections can disappear from your profile even though the PDF looks fine to you.

That is why two candidates with similar experience can get different outcomes: one resume is machine-readable, the other is not. Our checker simulates that first pass so you can fix problems early. For a deeper walkthrough, read our ATS resume score checker guide.

What the checker evaluates

  • Formatting — Can the parser read standard headings, fonts, and single-column layout without tables or graphics blocking text?
  • Keywords — Do your skills and experience reflect role-relevant terms recruiters filter on?
  • Section completeness — Are summary, skills, experience, and contact fields present and clearly labeled?
  • Impact signals — Do bullets include measurable outcomes, not just task lists?
  • Readability — Is wording clear and professional for both software and human reviewers?

Common ATS mistakes that lower your score

  • Multi-column layouts, text boxes, or tables in the body of the resume
  • Headers and footers that repeat contact info and confuse parsers
  • Icons, charts, or skill bars instead of plain-text skill lists
  • Missing keywords from the job description in skills and top bullets
  • Generic summaries with no target role or proof of results
  • Submitting the same resume to every posting without tailoring

Many of these issues appear in our resume mistakes guide. Fixing formatting first often produces the biggest score jump.

How to improve your ATS score step by step

  1. Switch to an ATS-safe template from our template gallery if your current design uses columns or decorative elements.
  2. Mirror the job title and top skills from the posting in your summary and skills section—naturally, not stuffed.
  3. Strengthen bullets with metrics using the bullet point formula.
  4. Rebuild in the resume builder if scores stay low— MakeResume enforces structure while you control the wording.
  5. Re-upload and re-check until you consistently score 80%+ for each target role.

Frequently asked questions

What is an ATS and why does it matter?

An Applicant Tracking System (ATS) is software employers use to collect, parse, and rank resumes before a recruiter reviews them. If the ATS cannot read your file, your application may never reach a human—even when you are qualified.

What is a good ATS resume score?

Aim for 80% or higher before you apply. Scores between 60–79% usually mean fixable keyword or formatting gaps. Below 60% often signals parsing problems worth fixing in a resume builder before you submit widely.

Does the ATS checker work on PDF and Word files?

Yes. Upload a PDF or DOCX export of your resume. Avoid scanned images, password-protected files, or heavily designed layouts with text boxes—the checker evaluates whether hiring software can extract your sections and keywords correctly.

How often should I check my resume?

Run a check after every major edit and whenever you tailor a resume for a new job posting. Keywords change by role, so a strong score for one application may drop if you reuse a generic version elsewhere.
