ATS Optimization Guide

Applicant Tracking Systems (ATS) are software applications that scan, parse, and rank resumes before they reach human recruiters. Studies show that 75% of resumes never make it past ATS filters. This guide will help ensure your resume gets through.

🤖 Understanding ATS

What is ATS?

An Applicant Tracking System is software used by companies to:

• Scan and parse resume content
• Extract key information
• Search for specific keywords
• Rank candidates based on criteria
• Store applicant information

Why It Matters

• 75% of large companies use ATS
• 98% of Fortune 500 companies use ATS
• Many resumes are rejected due to formatting issues
• Keywords determine ranking and visibility

✅ ATS-Friendly Formatting

Use Standard Structure

Do:

• ✅ Clear section headers (Experience, Education, Skills)
• ✅ Reverse chronological order
• ✅ Simple bullet points
• ✅ Standard fonts (Arial, Calibri, Times New Roman)
• ✅ Font size 10-12pt for body, 14-16pt for headers

Don't:

• ❌ Tables or columns
• ❌ Text boxes or graphics
• ❌ Headers and footers
• ❌ Images or logos
• ❌ Fancy fonts or scripts

File Format Considerations

Best Formats:

1. .docx - Most compatible with ATS
2. .pdf - Use only if specified (some ATS can't parse)
3. .txt - Plain text always works
