You spent hours perfecting your resume, tailored it to the job description, and hit submit with high hopes. Days pass, then weeks, and you hear nothing back. The frustrating reality is that your resume may never have been seen by a human. Before it reaches a recruiter's desk, it has to pass through an Applicant Tracking System — software that scans, parses, and ranks your resume automatically. If your resume is not formatted correctly, the ATS rejects it before anyone reads a single word.

Research from leading recruitment platforms suggests that approximately 75 percent of resumes are rejected by ATS systems before reaching a human reviewer. This is not because the candidates are unqualified — it is because the resumes are formatted in ways the software cannot read. This guide covers exactly what you need to do to make your resume ATS-friendly in 2025, with seven specific formatting rules and a section order that ATS systems prefer.

What Is an ATS (Applicant Tracking System)?

An Applicant Tracking System is software that companies use to manage their hiring process. When you apply for a job through a company's career page, job board (like LinkedIn, Indeed, or Naukri), or email, your resume is fed into the ATS. The system then:

• Parses your resume — Extracts text, contact information, work history, education, and skills
• Matches keywords — Compares the content against the job description to score relevance
• Ranks candidates — Assigns a score based on keyword match, experience level, and qualifications
• Filters applications — Surfaces the top-ranked candidates to the recruiter and rejects the rest

Popular ATS platforms include Greenhouse, Lever, Workday, Taleo, iCIMS, and BambooHR. Most large companies and many mid-size companies use some form of ATS. Even small companies that post on major job boards often use the board's built-in ATS functionality.

The critical thing to understand is that ATS software is not smart in the way humans are. It follows rigid parsing rules. If your resume uses formatting that the software does not understand, your information gets garbled, lost, or ignored — regardless of how qualified you are.

The 7 Formatting Rules for an ATS-Friendly Resume

Rule 1: No Tables

Tables are one of the most common reasons ATS systems fail to parse a resume correctly. Many candidates use tables to organize their skills, create sidebars, or align dates with job titles. While tables look clean to a human eye, most ATS systems read content linearly — from top to bottom, left to right — and cannot follow the logical structure of a table. Your carefully organized data ends up as jumbled, disconnected text.

What to do instead: Use simple line breaks, bullet points, and consistent indentation to organize information. Align dates to the right using tab stops or consistent spacing, not table columns.

Rule 2: No Headers and Footers

Many resume templates place your name, contact information, or page numbers in headers and footers. ATS systems typically skip headers and footers entirely when parsing. This means your name, phone number, email address, and LinkedIn URL could be completely invisible to the system.

What to do instead: Place all contact information in the main body of the document, at the very top of the first page.

Rule 3: Use Simple, Standard Fonts

Decorative fonts, script fonts, or unusual typefaces may look distinctive, but they cause parsing errors in ATS systems. Some ATS software maps characters based on standard font encodings, and non-standard fonts produce garbled text.

What to do instead: Use standard fonts that exist on every computer. The safest choices are:

• Arial — Clean, modern, universally supported
• Calibri — The default Microsoft Word font, highly readable
• Times New Roman — Classic, professional, always safe
• Helvetica — Clean and professional (Mac-friendly)

Use 10-12pt for body text and 13-16pt for your name and section headings.

Rule 4: Use Standard Section Headings

ATS systems look for specific section headings to categorize your information. Creative headings like "Where I Have Worked" instead of "Work Experience," or "What I Know" instead of "Skills," will confuse the parser.

Use these exact headings:

• Contact Information (or just your name at the top)
• Professional Summary (or Summary)
• Work Experience (or Professional Experience)
• Education
• Skills
• Certifications (if applicable)
• Projects (if applicable)

Rule 5: Match Keywords from the Job Description

This is the single most impactful thing you can do for ATS optimization. The ATS scores your resume largely based on keyword matching. If the job description mentions "project management," "Agile," "stakeholder communication," and "budget management," and your resume uses those exact terms, you score higher.

How to do it right:

• Read the job description carefully and highlight all key skills, tools, and qualifications
• Include these exact terms in your resume where they genuinely apply to your experience
• Use both the full form and abbreviation — for example, "Search Engine Optimization (SEO)"
• Do not stuff keywords unnaturally. Modern ATS systems also check for context, and keyword stuffing can actually lower your score

Rule 6: No Images or Graphics

ATS systems cannot read text inside images. This includes profile photos, logos, charts, infographics, icons, and any text placed inside image elements. If your key skills or achievements are presented as graphics, they are invisible to the ATS.

What to do instead: Present all information as plain text. If you want to show proficiency levels for skills, use words like "Advanced," "Intermediate," or "Beginner" instead of progress bars or star ratings.

Rule 7: Use the Right File Format

The two safest file formats for ATS are PDF and DOCX (Microsoft Word).

• PDF — Preserves your formatting across all devices and operating systems. Most modern ATS systems parse PDFs correctly. Always name your file professionally: "FirstName_LastName_Resume.pdf"
• DOCX — The native format for Microsoft Word. Some older ATS systems parse DOCX more reliably than PDF. Use this if the job posting specifically requests a Word document

Avoid JPG, PNG, or other image formats — ATS cannot read text from images. Avoid RTF (Rich Text Format) — it is outdated and poorly supported. Avoid Google Docs links — most ATS systems cannot access them.

The Ideal Section Order for ATS

ATS systems expect information in a specific order. While human recruiters may not care about section order, the ATS parser works more reliably when it finds content where it expects it. The recommended order is:

1. Contact Information — Name, phone, email, LinkedIn URL, city (no full street address needed in 2025)
2. Professional Summary — 2-3 sentences highlighting your experience, key skills, and what you bring to the role
3. Work Experience — Reverse chronological order (most recent job first). Include company name, job title, dates, and 3-5 bullet points per role
4. Education — Degree, institution, graduation year. Recent graduates can place this before work experience
5. Skills — A clean list of relevant technical and soft skills. Match these to the job description
6. Additional Sections — Certifications, projects, publications, languages, or volunteer work as relevant

Common ATS Resume Mistakes to Avoid

• Using a creative template — Multi-column layouts, infographic resumes, and design-heavy templates look impressive but fail ATS parsing. Save the creativity for your portfolio.
• Missing contact information — Double-check that your email and phone number are present and correct. A typo in your email means you will never receive a callback.
• Using abbreviations inconsistently — If you write "Mgr" in one place and "Manager" in another, the ATS may not connect them. Be consistent throughout.
• Submitting a generic resume — A one-size-fits-all resume scores lower than a tailored one. Customize your summary and skills section for each application.
• Overlooking the cover letter — Some ATS systems also parse cover letters. Use it as another opportunity to include relevant keywords.

Final Checklist Before You Submit

Before sending your resume to any job application, run through this quick checklist:

• No tables, columns, or text boxes
• No headers or footers with important information
• Standard font (Arial, Calibri, or Times New Roman)
• Standard section headings (Summary, Work Experience, Education, Skills)
• Keywords from the job description included naturally
• No images, icons, or graphics with text
• PDF or DOCX format
• Professional file name (FirstName_LastName_Resume.pdf)
• Contact information at the top, in the main body
• No spelling or grammatical errors

Getting past the ATS is the first hurdle. Once a human sees your resume, the content and relevance of your experience will determine the outcome. But if the ATS never lets your resume through, none of that matters. Format correctly, match the keywords, and give yourself the best chance of getting that interview.
