Most job applications go through an applicant tracking system before a human ever opens them. ATS software parses your resume, files it in a database, and lets recruiters search and filter the pile. If your resume can't be read cleanly, you don't get evaluated on your work. You get evaluated on the parsing.

The good news: making a resume that parses reliably is mostly about avoiding a small list of common mistakes. You don't need clever tricks, and you shouldn't sacrifice the parts that make your resume interesting to humans.

What an ATS actually does

An ATS reads your file, extracts the text, and tries to label the sections (contact, work history, education, skills). It stores those labels in a structured database. When a recruiter searches "Senior Engineer, Python, Berlin", the system returns resumes whose labels match. That's the whole machine.

So the goal isn't to "fool the ATS". The goal is to make your sections recognizable and your text searchable.

What trips ATS systems up

The patterns below are the ones we see fail most often when we audit submissions:

  • Tables and complex columns. Many older parsers read left-to-right across the entire page, so a two-column resume can scramble. Single-column layouts parse most reliably.
  • Text inside images. If your name or job title is a graphic, it's invisible to the parser. Use real text for every word that matters.
  • Headers and footers. Some systems skip them entirely. Don't put your contact info in the page header.
  • Decorative fonts. Anything beyond a standard sans-serif or serif risks the parser substituting characters. Stick to common fonts.
  • Section labels the parser doesn't recognize. "Career Highlights" reads as a heading to a human, but a strict ATS may need "Experience" or "Work Experience" to file it correctly.

What works

  • One column, top to bottom.
  • Standard section labels: Summary, Experience, Education, Skills.
  • Plain text for everything that matters, in a common font.
  • Dates in a consistent format (e.g. Jan 2023 - Mar 2025).
  • Contact details in the body, not in the header.

Every ImproveCV template is verified ATS-readable, so the parser finds every section the first time.

Don't stuff keywords

It's tempting to copy the entire job description into a hidden white-text block at the bottom of your resume. Don't. Modern ATS systems flag keyword stuffing, and recruiters who notice it will toss the resume faster than the bots would have.

What works instead: read the job posting, identify the 5-10 terms that matter most to that role, and use them naturally where they apply. If the posting calls a thing "stakeholder management" and you've been writing "working with leadership", rephrase that line.

The quick test

Before you send a resume out, save it as plain text and read what comes out. If your name, role, and bullets are intact and in order, the ATS will likely see the same thing. If your two-column layout reshuffled into a jumble, that's what the bot saw too.

Takeaway

ATS-friendly doesn't mean robotic. Use a clean, single-column structure with standard section labels and real text, then write the bullets like a person who wants to be hired. The boring part keeps you in the pile; the writing gets you to the interview.
