ATS Optimization Guide

Everything you need to know about Applicant Tracking Systems and how to get your resume past them.

What is an ATS?

An Applicant Tracking System (ATS) is software used by employers to manage the recruitment process. It collects, scans, sorts, and ranks resumes automatically before a human recruiter ever sees them. Over 98% of Fortune 500 companies and a growing majority of mid-size businesses use an ATS to filter candidates.

When you submit your resume online, the ATS parses the document into structured data -- extracting your contact info, work experience, education, and skills. It then scores your resume based on how well it matches the job description, keyword requirements, and formatting expectations set by the recruiter.

Why Resumes Get Rejected

Studies suggest that up to 75% of resumes are rejected by ATS before reaching a recruiter. Here are the most common reasons:

  • Wrong file format. Using images, infographics, or unsupported file types prevents parsing. Stick to PDF or DOCX.
  • Missing keywords. If your resume doesn't include the skills and terms from the job description, the ATS won't rank it highly.
  • Complex layouts. Tables, columns, headers/footers, and text boxes confuse parsers and cause data to be lost or misread.
  • Non-standard section headings. Creative headings like "My Journey" instead of "Work Experience" make it harder for ATS to categorize content.
  • Graphics and icons. Skill bars, progress circles, and icons are invisible to parsers. Use plain text instead.
  • Embedded fonts or special characters. Unusual fonts or characters can cause encoding errors during parsing.

How to Optimize Your CV for ATS

1. Use a clean, single-column layout

Avoid multi-column designs, tables, and text boxes. A simple top-to-bottom layout ensures the ATS reads your information in the correct order.

2. Match keywords from the job description

Read the job posting carefully and naturally incorporate relevant keywords into your resume. Include both the full term and common abbreviations (e.g., "Search Engine Optimization (SEO)").

3. Use standard section headings

Stick to conventional headings: "Summary," "Work Experience," "Education," "Skills," and "Certifications." The ATS expects these labels to categorize your information.

4. Save as PDF with selectable text

Export your resume as a real PDF (not a scanned image). Make sure all text is selectable when you open the file. This ensures the ATS can extract every word.

5. Quantify your achievements

Use numbers and metrics: "Increased revenue by 35%," "Managed a team of 12," "Reduced response time by 50%." Quantified achievements stand out to both ATS algorithms and human reviewers.

6. Keep formatting simple

Use standard fonts (Arial, Calibri, Times New Roman), consistent font sizes, and simple bullet points. Avoid graphics, images, logos, and decorative elements.

Common ATS Myths

"White text tricks can sneak in extra keywords."

Modern ATS software detects hidden text. This tactic can get your resume flagged and immediately rejected.

"Creative designs help you stand out."

They do -- but in a bad way. Fancy layouts reduce parseability. Your content, not your design, should make you stand out.

"ATS only matters for big companies."

Affordable ATS tools like Lever, Greenhouse, and Workable are widely used by startups and small businesses too.

"You need a different resume for every job."

You don't need to start from scratch, but you should tailor keywords and emphasis for each application. Jikan makes this easy with quick-edit and AI suggestions.
