How to create an ATS-friendly resume
Most large employers use an Applicant Tracking System (ATS) to scan resumes before a recruiter sees them. If your resume is not ATS-friendly, it can be rejected before a human reads a single line — even if you are the perfect candidate. This guide shows you how to format and keyword-optimize your resume so it passes ATS filters and reaches a hiring manager.
Quick checklist
- Use a clean, single-column layout
- Stick to standard fonts and sizes
- Include keywords from the job posting
- Save and upload as a PDF
- Avoid tables, headers, and graphics
- Use simple section headings
What is an ATS?
An Applicant Tracking System (ATS) is software that reads, parses, and ranks resumes. It extracts information like your name, contact details, work history, skills, and education, then compares it against the job description. Recruiters use ATS results to decide which candidates move forward. If the system cannot read your resume, you may be filtered out regardless of your qualifications.
ATS resume formatting rules
Formatting is the most common reason a resume fails ATS parsing. Follow these rules to keep your document machine-readable.
Use a single-column layout
Multi-column designs confuse parsers. Keep every section in one vertical flow so the ATS reads your experience in the correct order.
Choose a standard font
Arial, Calibri, Garamond, Georgia, and Helvetica are safe choices. Avoid decorative or script fonts that OCR may not recognize.
Keep font size readable
Use 10–12 pt for body text and 14–16 pt for section headings. Tiny fonts can be flagged or skipped.
Avoid tables, text boxes, and graphics
ATS software often strips or ignores content inside tables, text boxes, charts, and images. Use plain bullet lists instead.
Skip headers and footers
Important information placed in a header or footer — like your phone number or email — may be discarded by the parser.
Use simple section headings
Stick to conventional labels: Summary, Experience, Education, Skills, Certifications. Creative titles like ‘My Journey’ may not be recognized.
Keyword optimization for ATS
Keywords are how an ATS decides whether your resume matches a role. The system compares your document against the job description, so the closer your language matches the posting, the higher you rank.
Mirror the job description
If the posting asks for ‘project management,’ use that exact phrase rather than ‘led initiatives.’ Match job titles, skills, tools, and certifications where they honestly apply.
Include hard and soft skills
List technical skills like Python, Salesforce, or Excel separately from soft skills like communication or leadership. Many ATS products parse a dedicated skills section first.
Use full terms and acronyms
Write ‘Search Engine Optimization (SEO)’ or ‘Certified Public Accountant (CPA)’ so you are covered whether the ATS searches for the full phrase or the acronym.
Avoid keyword stuffing
Repeating the same word dozens of times looks unnatural and can hurt your ranking. Use keywords naturally and in context.
File type matters
PDF is the safest file format for most modern ATS platforms because it preserves your layout while remaining machine-readable. Avoid image-only PDFs or scanned documents; if the file is a picture, the ATS cannot extract text. InstantCV exports a text-based PDF that ATS parsers can read.
