Why there's no percentage here
Real applicant tracking systems — Workday, Greenhouse, iCIMS — don't produce a "compatibility score." They parse your resume into fields, and separately a recruiter searches or filters by keyword. That's it.
So any tool showing you "87% ATS compatible" invented that number with its own private formula. The checks underneath are usually real; the score wrapping them is theatre. We show you the checks and skip the theatre — every item below is something you can verify yourself.
Questions
Is there a real ATS score?
No. Applicant tracking systems don't emit a compatibility percentage — they parse your resume into structured fields, and recruiters filter by keyword separately. Any percentage you've seen was calculated by that tool alone, which is why two "ATS checkers" will happily give the same resume wildly different numbers.
How do I know if my resume is ATS-friendly?
Quick test you can run yourself: copy the text out of your resume and paste it into Notepad or TextEdit. If it comes out in the right order, with nothing missing, scrambled, or merged, an ATS can read it too. Then check the basics — a single column, standard headings like Experience and Education, a common font, no tables or graphics, and keywords from the posting.
Do you store my resume?
No. Your file is read in memory to run the check and is never written to disk or kept afterwards. Nothing about your resume is retained once the results come back.
Does hidden white text trick an ATS?
No — it's a good way to get thrown out. Hidden or white-on-white keyword text is a known trick that modern systems flag, and any recruiter who selects the text sees it instantly. This checker flags unnatural keyword repetition rather than rewarding it. If you're short on keywords, the fix is adding real ones that are actually true for you.
What if my resume fails a check?
Every failed item comes with a specific fix. Formatting problems (columns, tables, scanned images) are solved by rebuilding on a clean single-column template. Content gaps (missing keywords, no summary, no measurable results) are things you can add in the builder.
