Most ATS software doesn't reject resumes because they're a bad fit for the job — it rejects them because it literally can't read them correctly. A recruiter never sees a resume that got mangled on import. Here's what actually breaks parsing, based on the checks that matter most.
If your resume is a scanned image or a PDF exported from a design tool without embedded text, an ATS sees a blank page. Export directly from a word processor or a PDF generator that preserves selectable text — you should be able to highlight and copy every word in a PDF viewer.
Two-column resumes look great to a human eye but most ATS parsers read left-to-right, top-to-bottom in a single stream — so a skills column next to an experience column gets interleaved into nonsense. Same problem with tables used for layout. Stick to a single column.
"Where I've Made Impact" might read better than "Work Experience" to a person, but ATS software matches on standard section names. Use conventional headings: Experience, Education, Skills, Summary.
Many ATS parsers skip document headers and footers entirely — so if your name, email, or phone number only live there, they may never get extracted at all. Put contact details in the main body, at the top of the document.
A phone icon or email glyph placed directly next to your phone number or email address can break how some parsers tokenize that field. Plain text is safer than decorative icons for anything the ATS needs to extract.
"2019 - Present" or "Jan 2019 - Mar 2022" parse reliably. Creative date formatting, or omitting dates entirely, makes it hard for an ATS (and a recruiter) to calculate your experience automatically.
Extremely short resumes often mean missing sections the ATS expects; resumes well over two pages tend to bury the keywords that matter under less relevant detail. One to two pages is the safe range for most roles.
Checking all seven manually is doable, but it's easy to miss layout issues that aren't visible just by looking at the file. ATSBuddy runs these checks (and more) automatically and gives you a deterministic score — the same resume always scores the same, because it's not guessed by an AI.
