ATS-friendly resume: the 10 rules that really count

The internet is full of endless lists of "secret ATS tricks". The truth is less spectacular and better: machine readability is craft, not magic. Here are the ten rules that actually count — each with the honest why. No robot rejects you (that's a myth); the point is that your profile arrives complete in the system.

Rule 1: One column

Parsers read line by line across the full width. Two columns can lead to mixed, shredded text. The full trade-off including the two-versions strategy is here.

Rule 2: PDF with a text layer

Export directly, never scan. A PDF without a text layer is an empty page for every system — the only mistake on this list that makes you completely invisible. Quick test and details: PDF or Word.

Rule 3: Standard headings

"Work experience", "Education", "Skills", "Languages". Parsers map content via headings — no system understands "My journey" or "My superpowers". Boring is correct here.

Rule 4: Contact details as text in the document body

Not in the header or footer (some parsers skip them entirely), not as icon graphics. Name, phone, email and city belong on the first page as normal text.

Rule 5: No icon fonts or skill bars

Symbols from icon fonts turn into character garbage; bar charts are invisible graphics. Write "Excel (advanced)" instead of "Excel ████". Design templates are especially prone — see Canva resumes and ATS.

Rule 6: Consistent, parseable date formats

MM/YYYY throughout (03/2021 – 08/2023). Three different formats in the same document confuse parsers building your timeline — and humans skimming it.

Rule 7: Write out skills — honestly and concretely

Everything that counts, as text: tools, methods, languages, ideally with level or years ("SAP TM, 3 years"). But only what's true — keyword stuffing gets exposed and hurts.

Rule 8: No tables or text boxes for structure

What's built as a table or floating text box in Word often arrives in the wrong order when parsed. Structure comes from headings and paragraphs, not invisible grids.

Rule 9: Clear chronology without unexplained gaps

Positions sorted in reverse, each with period, role, company. Name gaps longer than three months briefly (further training, family time, reorientation) — it pre-empts questions, machine and human alike.

Rule 10: Professional file name

CV_Firstname_Lastname.pdf. Recruiters see the file name in the attachment list — "resume_final_new2(3).pdf" looks like your desk after moving house.

The double win

The beauty of these rules: they cost nothing in impact on humans — quite the opposite. A single-column, clearly structured document with standard headings is also faster for recruiters to grasp. Machine readability and readability turn out to be the same craft.

Rule 11 (bonus): Verify instead of believing

Whether you meet all ten rules is invisible to the naked eye — but takes 60 seconds with the free resume check: it tests text layer, columns, headings, date formats, icons and more, compares the original with what a parser reads, and tells you in plain language what to improve. Anonymous, no account — and after your corrections you simply check again.
