Optimize your resume for the ATS
A free ATS optimizer that shows exactly what the applicant tracking system reads: your parse score, the keywords you're missing for the job, and the precise fixes. Paste, optimize, rescan — your resume never leaves your browser.
Quick answer:To optimize a resume for the ATS, make it parse cleanly (single column, standard headings, text-based file) and match the job description's keywords for skills you genuinely have. This tool scores both for free and shows the exact gaps to fix.

What ATS optimization actually fixes
More than 90% of employers surveyed run resumes through an applicant tracking system before a human reads them (Harvard Business School, 2021). Optimization isn't about tricking the software — it's about removing the two reasons a strong resume goes unseen: the parser can't read it cleanly, or it doesn't contain the words the recruiter searches for.
The ATS optimization checklist
- Match the job's keywords — mirror the exact skills and titles from the job description (for things you genuinely have). This is the #1 factor you control.
- Single-column layout — parsers read top-to-bottom; two columns interleave your content and scramble the parse.
- Standard section headings — Experience, Education, Skills. Creative labels confuse the parser's section detection.
- Text-based file — if you can select the text in your PDF, the parser can read it. Canva/design exports often can't be read.
- Contact details in the body — not in a header, footer or text box, which are frequently dropped.
- Real dates & plain bullets — no tables, icons, or graphical skill bars, which add nothing the parser can use.
The scanner above checks every one of these against your resume and, when you paste the job posting, shows the specific keywords you're missing — so optimization becomes a checklist you can actually finish, not guesswork.
Optimize, rescan, repeat — free
Optimization is iterative. Apply the fixes, paste your updated resume, and scan again as many times as you want — it's free and unlimited, no signup. The optional $9 report gives you every issue with line locations, the complete missing-keyword list, and bullet rewrite blueprints — the full optimization in one pass, for a one-time price rather than a subscription.
Frequently asked questions
What does ATS optimization mean?
ATS optimization means formatting and wording your resume so an applicant tracking system can parse it cleanly and match it to the job. In practice that's two things: a clean structure the parser reads correctly (single column, standard headings, real dates, no tables or text boxes), and the right keywords — the skills and titles from the specific job description, for things you genuinely have. Optimize both and your resume surfaces in recruiter searches instead of getting buried.
How do I optimize my resume for the ATS for free?
Paste your resume above (and the job description) and the free scan shows your parse score, a category breakdown, your top issues, and a preview of the keywords you're missing — no signup, nothing uploaded. Fix what it flags, paste the updated version, and rescan as many times as you like. The full optimization report (every issue with locations, all missing keywords, and bullet rewrites) is an optional one-time $9.
What are the most important ATS optimization factors?
Keyword match against the specific job description is the single biggest factor you control — recruiters search and filter on those terms. After that: a single-column layout, standard section headings (Experience, Education, Skills), a text-based file the parser can read, real date formats, and contact details in the body rather than a header or text box. Decorative templates with columns, tables and icons are the most common things that quietly break optimization.
Is keyword stuffing good for ATS optimization?
No. Modern systems and the recruiters reading the results penalize obvious stuffing, and a wall of keywords reads as spam to the human who makes the decision. Optimize by including the job's important terms naturally — in real achievement bullets and a skills section — for skills you actually have. The goal is a resume that's both findable by the software and convincing to the person.
Does the optimizer upload my resume anywhere?
No. The entire analysis runs in your browser — your resume text is never sent to a server, and there's no account or email. You can verify it in your browser's network tab. Optimization without handing your personal details to a tool you've never used.
