ATS Optimization Guide
Over 90% of Fortune 500 companies use Applicant Tracking Systems (ATS) to filter resumes before a human ever sees them. Here's how to make sure yours gets through.
What Is an ATS?
An ATS is software that scans, parses, and ranks resumes based on keywords, formatting, and structure. Popular systems include Workday, Greenhouse, Lever, and Taleo.
Common ATS Rejection Reasons
1. Complex Formatting
ATS systems struggle with:
- Tables and columns — Use single-column layouts
- Headers and footers — Put all content in the main body
- Text boxes — Use standard paragraphs instead
- Graphics and icons — Remove decorative elements
- Custom fonts — Stick to Arial, Calibri, or Times New Roman
2. Missing Keywords
ATS systems match your resume against the job description. If critical keywords are missing, you'll be filtered out.
How to fix it:
- Read the job description carefully
- Identify required skills, tools, and qualifications
- Include exact keyword matches (e.g., "project management" not just "PM")
- Use both acronyms and full forms: "Search Engine Optimization (SEO)"
3. Non-Standard Section Headers
ATS systems look for standard sections:
| Use This | Not This |
|---|---|
| Work Experience | Where I've Been |
| Education | Academic Journey |
| Skills | What I'm Good At |
| Professional Summary | About Me |
4. Wrong File Format
- Best: PDF (most universally supported)
- Good: DOCX
- Avoid: Pages, Google Docs links, images
