Optimizing for ATS Systems

Michael Chen — Resume Expert • June 10, 2026 • 10 min read

Ensure your resume actually reaches a human. Understand how Applicant Tracking Systems work and how to format your experience for maximum visibility.

What Is an ATS?

An Applicant Tracking System (ATS) is software used by employers to sort, filter, and rank job applications. Over 98% of Fortune 500 companies use ATS software, and many mid-size companies do as well. If your resume is not ATS-optimised, it may never reach a human recruiter.

Formatting Rules That Matter

  • Use standard section headings: Experience, Education, Skills, Projects
  • Stick to simple fonts like Arial, Calibri, or Helvetica
  • Avoid tables, text boxes, headers/footers, and columns
  • Save as .docx or .pdf (check the application instructions)
  • Use standard date formats: Jan 2024 - Present

Keyword Optimisation

ATS systems scan for keywords from the job description. Mirror the language used in the posting without keyword stuffing.

Pro tip: Copy the job description into a word cloud tool. The most prominent words are likely the keywords the ATS is scanning for.

  1. Read the job description and highlight the key skills and qualifications
  2. Naturally incorporate those exact terms into your experience bullets
  3. Include both acronyms and full terms: Project Management Professional (PMP)
  4. Add a dedicated Skills section that lists technical and soft skills
  5. Tailor your resume for each application rather than using a generic version

The number one mistake I see is candidates using fancy designs that look great to human eyes but are completely unreadable to ATS software.

Testing Your Resume

Before submitting, copy-paste your resume text into a plain text editor. If the content is jumbled or sections are missing, an ATS will have the same problem.

Summary

ATS optimisation is not about gaming the system; it is about presenting your experience in a format that both software and humans can understand clearly. Focus on clean formatting, relevant keywords, and measurable achievements.
