What an applicant tracking system actually does to your CV

An applicant tracking system is a database. When you upload a CV it extracts the text, tries to work out which parts are your name, your jobs and your skills, and stores them as fields a recruiter can search.

Almost everything that goes wrong happens in that extraction step.

What actually breaks parsing

Text stored as an image. If your CV was exported as a picture — or designed in a tool that outlines the fonts — the parser sees nothing at all. Test this: open your PDF, select the text and copy it. If nothing selects, no system can read it.

Contact details in a header or footer. Page headers and footers sit outside the main text flow. Many parsers skip them entirely, which produces a candidate record with no email address. Keep contact details in the body of the page.

Two-column layouts. Columns are a visual arrangement. Flattened to text, a two-column CV often interleaves — a line from the sidebar, a line from the main column — and the result is unusable. This is the single biggest risk in an otherwise attractive template.

Tables used for layout. Some parsers read tables cell by cell in an order that has nothing to do with how it looks.

Unusual section headings. Parsers look for "Experience", "Education", "Skills". "Where I've Made An Impact" is a heading no classifier recognises.

What does not matter

A great deal of ATS advice is superstition.

• Keyword stuffing in white text. This has been detected for over a decade and gets applications discarded when a human notices.
• Avoiding PDFs entirely. Modern systems read PDFs fine. It is image-based PDFs that fail.
• A specific "ATS-friendly font". Any common font with a real text layer parses identically.
• Exactly one page. A hard limit that exists in advice columns, not in parsing software.

The unglamorous checklist

1. One column, in the order a person would read it.
2. Contact details in the body, not a footer.
3. Standard headings: Summary, Experience, Education, Skills.
4. No layout tables, no text inside images.
5. Restrained letter-spacing on headings — widely tracked capitals sometimes extract as S U M M A R Y, which matches nothing.
6. Save as PDF with a real text layer.

Test it yourself in thirty seconds

Copy all the text out of your finished PDF and paste it into a plain text editor. That is approximately what the system stores.

Is your name the first line? Is your email present? Are the jobs in order, each with its dates? If yes, your CV parses. If the columns have interleaved or the contact details have vanished, change the layout — not the wording.

Every template on this site marked ATS-safe already follows the checklist above.
