Last Updated: January 2026 | Transform your resume from ATS-rejected to ATS-approved with this actionable guide.

Quick Answer: How to Optimize Your CV for ATS

To optimize your CV for ATS systems, you need to: (1) Use standard formatting (simple fonts, clear sections, no graphics), (2) Include relevant keywords from job descriptions naturally throughout your resume, (3) Use standard section headings (Experience, Education, Skills), (4) Save as a Word document or simple PDF, (5) Ensure all information is machine-readable (no images or tables), and (6) Match your skills and experience to the job requirements. Following these steps can increase your ATS pass rate from 25% to 85% or higher.

If you're applying to jobs but not getting callbacks, your CV might be getting rejected by Applicant Tracking Systems (ATS) before it even reaches a human recruiter.
