How to Make Your Resume ATS-Friendly (2026 Guide)

Most resumes are rejected before a human ever reads them. Companies use applicant tracking systems, or ATS, to scan, store, and rank every resume that comes in, and the ones the software cannot read or match are filtered out automatically. The good news is that making your resume ATS-friendly is straightforward once you know the rules. Here is exactly how.

What is an ATS, and why it rejects resumes

An applicant tracking system is software that parses your resume into data, stores it, and ranks it against the job. Recruiters then search and filter by keywords. Two things get resumes rejected: formatting the ATS cannot parse, so your experience comes through garbled or blank, and missing the keywords the employer is scanning for, so you rank near the bottom. Most large companies and many smaller ones use one, so writing for the ATS is no longer optional.

The ATS-friendly formatting rules

Keep the layout simple and machine-readable. The essentials:

• Use a single-column layout. Avoid multiple columns, tables, and text boxes, which scramble when parsed.
• Stick to standard fonts like Arial, Calibri, or Georgia at 10 to 12 points.
• Use standard section headings (Work Experience, Education, Skills) so the ATS knows where everything goes.
• Skip images, logos, icons, charts, and graphics. An ATS cannot read them.
• Keep your contact details in the body of the resume, not in the header or footer, which some systems ignore.
• Use simple round bullet points, not decorative symbols.
• Save as a .docx or PDF, following whatever the job posting asks for.

The sections an ATS expects

Use a familiar structure so the system maps your information correctly: contact information, a short professional summary, work experience in reverse chronological order with clear dates, a skills section, and education. Creative section names like “Where I have made an impact” confuse the parser, so keep headings conventional.

Match the job's keywords

Once your resume is parsed cleanly, the ATS ranks it by how well it matches the job description. Mirror the exact skills, tools, and terms the posting uses, as long as you genuinely have them. For a full walkthrough, see our guide on resume keywords.

Common ATS mistakes to avoid

• Two-column or table-based layouts that scramble when parsed
• Images, icons, or text placed inside graphics
• Putting your name or contact info only in the header
• Creative section titles the ATS cannot recognize
• Submitting a PDF when the posting specifically asks for a .docx
• Missing the key skills and terms from the job description

Frequently asked questions

Is a PDF ATS-friendly?

Most modern systems read PDFs fine, but if a posting asks for a .docx, send that. When you are unsure, a clean .docx is the safest bet.

Do ATS systems read headers and footers?

Many ignore them, so never put your name, email, or phone only in the header. Keep that information in the main body of the resume.

How many keywords should I include?

Mirror the job description naturally, including only skills you actually have. Do not stuff keywords or hide them in white text, which gets flagged.
