If you've been applying to jobs with little to no response, your resume might be failing the ATS test — not because you're unqualified, but because a robot couldn't read it properly.
ATS (Applicant Tracking System) software is used by over 90% of large companies to filter resumes before a human ever sees them. The system scans, parses, and ranks your resume based on keywords, formatting, and structure. If it can't understand your resume, you're rejected in milliseconds.
Here's how to build an ATS-friendly resume that both the software and recruiters will love.
1. Use a Simple, Clean Layout
ATS parsers are easily confused by complex formatting. Stick to these rules:
- One-column layout — multi-column designs often get scrambled
- Standard section headings — "Work Experience", "Education", "Skills" (not fancy alternatives)
- No tables, text boxes, or graphics — these can hide your text from the parser
- Consistent fonts — use standard fonts like Inter, Arial, or Calibri throughout
A good rule of thumb: if you can copy-paste your resume into a plain text file and it still reads well, it will pass ATS parsing.
2. Use the Right Keywords
ATS ranks resumes by keyword relevance. The key is matching the job description.
How to find the right keywords:
- Save 5–10 job descriptions for roles you're targeting
- Highlight recurring terms — skills, tools, certifications, soft skills
- Create a keyword list organized by category
Example keyword categories for a Software Developer:
| Category | Keywords |
|---|---|
| Languages | JavaScript, TypeScript, Python, Go |
| Frameworks | React, Node.js, Next.js, Django |
| Tools | Git, Docker, AWS, CI/CD |
| Soft skills | Leadership, Communication, Agile |
| Certifications | AWS Certified, Google Cloud |
Where to place keywords:
- Professional summary (2–3 sentences)
- Work experience bullet points
- Skills section
- Certifications
Important: Don't keyword-stuff. Use keywords naturally in context. Modern ATS can detect stuffing and may penalize you.
3. Choose the Right File Format
PDF is generally the safest choice for ATS compatibility. It preserves your formatting and is readable by most modern ATS systems.
- Preferred: PDF (save as "PDF/A" or standard PDF)
- Acceptable: DOCX (Microsoft Word)
- Avoid: JPEG, PNG, scanned documents
4. Optimize Your Section Headings
ATS relies on standard section headings to parse your resume correctly.
Use these: "Work Experience", "Education", "Skills", "Certifications", "Projects", "Summary" or "Professional Summary"
Avoid: "Where I've Worked", "What I Know", "My Journey"
5. Include a Professional Summary
A 2–3 sentence summary at the top helps both ATS and recruiters quickly understand who you are. It should include:
- Your title and years of experience
- Your top 2–3 skills or specialties
- What kind of role you're seeking
Example: "Senior Frontend Developer with 6+ years of experience building scalable React applications. Proficient in TypeScript, Next.js, and performance optimization. Seeking a senior engineering role in a product-focused team."
6. Use Standard Date Formats
ATS can struggle with non-standard date formats. Stick to:
- Month YYYY – Month YYYY (e.g., "June 2020 – Present")
- Month YYYY – Month YYYY (e.g., "January 2018 – May 2020")
Avoid relative dates like "3 years" or "currently" — these can confuse parsers.
7. Test Your Resume Before Submitting
Before you send your resume, run it through these checks:
- Plain text test — copy your resume content into Notepad. If sections are out of order or text is missing, your layout needs fixing.
- ATS check — use ProResume's built-in ATS check to see how your resume scores before you apply.
- PDF text extraction — open your PDF and try to select all text (Ctrl+A). If some text is unselectable, ATS won't read it either.
8. Avoid These Common ATS Pitfalls
| Mistake | Why It Fails | Fix |
|---|---|---|
| Headers & footers with contact info | Many ATS can't read headers/footers | Put contact info in the main body |
| Abbreviations without full forms | "5 yrs exp — AWS, GCP, K8s" might miss keywords | Spell out at least once |
| Graphics & icons in contact section | Phone icons or email icons may hide text | Use plain text for contact |
| Unusual fonts or special characters | Parsers may drop unicode characters | Stick to ASCII + standard punctuation |
Frequently Asked Questions
Is a PDF or Word document better for ATS?
For most modern ATS systems, a text-based PDF is the safest choice — it preserves your layout and stays readable. If a job posting specifically asks for a Word file, submit a clean, one-column DOCX instead.
How many keywords should I add to my resume?
There's no magic number. Focus on the skills, tools, and qualifications that appear most often across the job descriptions you're targeting, and weave them in naturally. Quality and relevance beat raw quantity.
Do ATS systems read headers and footers?
Many older ATS parsers ignore or scramble text inside headers and footers. Keep critical details like your name, phone number, and email in the main body of the resume.
Will an ATS-friendly template guarantee I pass?
A clean template gives you the best possible start, but content still matters. Pair an ATS-friendly layout with the right keywords and standard headings to maximize your score.
