What is an ATS and Why Should You Care?

An Applicant Tracking System (ATS) is software that companies use to collect, scan, and rank job applications before human recruiters see them. Think of it as a gatekeeper that decides whether your resume makes it to the hiring manager's desk or gets auto-rejected.

Here's why this matters for job seekers: approximately 98% of Fortune 500 companies and 66% of large companies use ATS software.[1] If you're applying to companies like Infosys, TCS, Wipro, or any startup with 50+ employees, your resume is likely being screened by an ATS first.

The problem? Most ATS systems were built for recruiters, not job seekers. They struggle with creative formatting, graphics, and non-standard layouts. A resume that looks beautiful to you might appear as scrambled nonsense to an ATS parser.

The good news: once you understand how ATS works, beating it is straightforward. These 12 tips will help your resume pass the initial screening and land in front of actual humans.

12 ATS Resume Tips That Actually Work

What Section Headings Do ATS Systems Recognize?

ATS software looks for specific section labels to categorize your information. Creative headings like "My Journey" or "Where I've Made an Impact" confuse the parser and cause it to skip entire sections.

ATS-safe headings to use:

• Work Experience (or Professional Experience, Employment History)
• Education
• Skills (or Technical Skills, Core Competencies)
• Certifications
• Summary (or Professional Summary, Career Objective)

Avoid: "What I Bring to the Table," "My Toolbox," "Career Highlights" as main section headers. Stick to industry-standard labels.

Which File Format Works Best for ATS Resumes?

This is the most common question I get: PDF or Word?

The safest answer is .docx (Microsoft Word format). It has 99% compatibility across all ATS platforms. Modern systems like Greenhouse, Lever, and Workday can read PDFs, but older ATS software (still used by many companies) struggles with them.

When to use each format:

• .docx: Default choice, especially for large corporations and government jobs
• .pdf: Only if the job posting specifically requests it or allows it
• .txt: Last resort if formatting doesn't matter (rare)

Never submit: Image-based PDFs, scanned documents, or PDFs created from design tools like Canva or Photoshop. ATS cannot extract text from images.

Why Should You Avoid Tables and Graphics in ATS Resumes?

During my testing, I found that ATS parsers read resumes from left to right, top to bottom, just like you're reading this article. When you put information in tables or text boxes, the ATS reads across both columns before moving down, scrambling the content.

Example of what goes wrong:

What you see: [Left column: "Marketing Manager"] [Right column: "2020-2023"] [Left column: "Google Inc."] [Right column: "Mumbai, India"] What ATS reads: "Marketing Manager 2020-2023 Google Inc. Mumbai, India"

While that example isn't terrible, complex tables completely break. I've seen ATS parse a two-column resume as "Python Java Marketing Sales Analyst Designer 2020 2022."

Safe alternative: Use simple line breaks and standard formatting. Put job title and dates on one line, company and location on the next line.

How Do You Match Keywords for ATS Optimization?

This is where ATS ranking happens. The system scans your resume for keywords from the job posting and assigns a match score. Resumes with 70-80% keyword match get prioritized.

How to identify must-have keywords:

1. Copy the job description into a word cloud generator (or just read it carefully)
2. Highlight hard skills (Python, SQL, AutoCAD), certifications (PMP, AWS), and repeated phrases
3. Note both acronyms and full terms (e.g., "SEO" and "Search Engine Optimization")
4. Focus on skills in the "Requirements" section, not the "Nice to Have" section

Where to place keywords naturally:

• Skills section: List 8-12 core skills that match the job
• Work experience bullets: Use keywords in context of your achievements
• Summary section: Mention 3-4 top keywords in your opening paragraph

Pro tip: If the job description says "managed cross-functional teams," use that exact phrase instead of "led diverse groups." ATS looks for exact or close matches.

Which Fonts Are ATS-Friendly?

Fancy fonts, custom typography, and decorative scripts cause parsing errors. ATS software is trained on common fonts and struggles with anything unusual.

ATS-safe fonts:

• Arial
• Calibri
• Times New Roman
• Georgia
• Helvetica
• Verdana

Font size guidelines:

• Body text: 10-12 point
• Your name: 14-16 point
• Section headings: 12-14 point

Smaller than 10pt is hard for recruiters to read. Larger than 12pt looks unprofessional and wastes space.

Should You Use Headers and Footers on ATS Resumes?

Many ATS systems completely ignore text in headers and footers. This is a critical mistake I see constantly: job seekers put their contact information in the header thinking it looks clean, then the ATS can't find their phone number or email.

Never put these in headers/footers:

• Contact information (name, phone, email, address)
• Important keywords or job titles
• Any content you want ATS to read

What you CAN put there (if anything):

• Page numbers (e.g., "Page 2 of 2")
• Your name on page 2+ (as a backup, also put it in the main body)

Best practice: don't use headers or footers at all. Put everything in the main document body.[4]

How Should You Handle Acronyms in ATS Resumes?

Different ATS systems search for keywords differently. Some look for "SEO," others search for "Search Engine Optimization." To be safe, use both.

Format: Full term (Acronym) then acronym only

First mention: "Implemented Search Engine Optimization (SEO) strategies..." Later mentions: "SEO efforts increased organic traffic by 40%..."

Common acronyms to spell out:

• CRM (Customer Relationship Management)
• ERP (Enterprise Resource Planning)
• KPI (Key Performance Indicator)
• ROI (Return on Investment)
• B2B (Business-to-Business)
• AI/ML (Artificial Intelligence/Machine Learning)

What Bullet Point Styles Work Best for ATS?

Stick with simple, universally recognized bullet point symbols. The basic round bullet (•) or simple dash (-) works across all ATS platforms.

Safe bullet styles:

• • Round bullet (default in most word processors)
• - Simple dash or hyphen
• ○ Hollow circle (if you need visual hierarchy)

Avoid:

• ✓ Checkmarks
• → Arrows
• ★ Stars or special symbols
• Custom icons or emojis
• Images used as bullets

Should You Include a Skills Section for ATS?

A dedicated Skills section is ATS gold. It's where the system looks first for keyword matches. Format it as a simple list or a few short rows of comma-separated skills.

How many skills to list: 10-15 is the sweet spot. Too few looks light on experience. Too many (20+) looks like keyword stuffing.

Focus on hard skills, not soft skills:

Good (hard skills ATS can match): Python, SQL, Tableau, Google Analytics, A/B Testing, Project Management, Salesforce CRM, Agile/Scrum Bad (soft skills ATS ignores): Leadership, Communication, Problem-solving, Team player, Detail-oriented

Avoid skill rating bars or graphs: Those visual elements don't translate to ATS. Just list the skills as text.

include the right ATS resume keywords for your field.

Which Resume Format Is Best for ATS?

ATS systems are designed to parse chronological resumes (most recent job first, working backward). Functional resumes that group experience by skill type confuse the ATS parser.

Best ATS-friendly formats:

• Chronological: Work experience listed by date, newest first (best for most people)
• Hybrid: Skills summary at top, followed by chronological work history (good for career changers)

Avoid: Functional resumes that group experience by skill categories rather than jobs. ATS can't determine where and when you worked.

How Should You Name Your Resume File for ATS?

This seems minor, but weird filenames can cause upload errors or make your resume hard for recruiters to find later.

Best practice format: FirstName-LastName-Resume.pdf or FirstName-LastName-Resume.docx

Good: Sarah-Mitchell-Resume.docx Bad: - resume_final_FINAL_v3.docx - My Resume 2026.pdf - Résumé (special characters cause encoding issues) - SarahResume05262026.docx (dates make it look outdated quickly)

How Can You Test Your Resume Before Applying?

Before you submit applications, test your resume with an ATS checker to see exactly how it will be parsed. These tools simulate what ATS software sees and flag formatting issues.

What to look for in scan results:

• Contact information extracted correctly: Name, phone, email, location all showing up
• Work history in the right order: Most recent job first, dates parsing correctly
• Skills identified: Your skills section appearing in the ATS skills field
• No missing sections: Education, certifications all captured

Common ATS Resume Mistakes to Avoid

Even with the tips above, certain mistakes keep tripping people up. Here's what I see most often when reviewing resumes that failed ATS screening:

Putting Contact Info in Images or Headers

I've reviewed hundreds of resumes where candidates created a beautiful header graphic with their name and contact details. ATS reads it as blank space. The system literally cannot find who submitted the application.

Using Tables for Work Experience

Two-column layouts look clean but break parsing. Your job title ends up in a different field than your employer, dates get scrambled, and achievements disappear entirely.

Creative Job Titles That Don't Match Industry Standards

If the job posting says "Marketing Manager" and your current title is "Brand Experience Architect," the ATS won't make the connection. Use standard industry titles, even if your business card says something different.

You can mention the official title in your work description, but lead with the industry-standard version that matches job postings.

Keyword Stuffing

Some job seekers hide white text with keywords in the background or list every technology they've vaguely heard of. Modern ATS systems detect this (they check for keyword density and context), and many will auto-reject obvious stuffing.

Rule of thumb: if you can't speak confidently about a skill for 2 minutes in an interview, don't list it.[7]

Forgetting to Customize for Each Application

The biggest mistake isn't technical - it's sending the same generic resume to every job. ATS ranks resumes by keyword match percentage. If the job emphasizes "cloud architecture" and your resume says "infrastructure design," you lose points even if they mean the same thing.

Spend 10 minutes tailoring your resume for each application. Adjust your skills section, tweak your summary, and mirror the job description's language.

Best ATS-Friendly Resume Format (Template Breakdown)

Here's the exact structure that passes ATS screening reliably. This is what I recommend to all my clients, and it works for 95% of job seekers:

Section Order (Top to Bottom):

1. Contact Information (centered or left-aligned, in document body)
   • Your Name (14-16pt font)
   • Phone Number
   • Email Address
   • City, State (full address not required anymore)
   • LinkedIn URL (optional but recommended)
2. Professional Summary or Career Objective (2-4 sentences)
   • Include your job title/target role
   • Mention 3-4 top keywords from the job description
   • Highlight years of experience
   • Keep it under 50 words
3. Skills (10-15 skills in a simple list)
   • Hard skills only (software, tools, certifications)
   • Match job description keywords
   • Simple format: comma-separated or bulleted list
4. Work Experience (reverse chronological order)
   • Job Title | Company Name
   • Location | Dates (Month Year - Month Year)
   • 3-5 bullet points per role
   • Start bullets with action verbs
   • Include quantifiable achievements where possible
5. Education
   • Degree | Major
   • University Name
   • Location | Graduation Year
   • GPA (if 3.5+ and recent graduate)
6. Certifications (if applicable)
   • Certification Name | Issuing Organization | Year

Spacing and Formatting Guidelines:

• Margins: 0.5" to 1" on all sides
• Line spacing: 1.0 to 1.15 (not more than 1.5)
• Font size: 10-12pt for body text
• Bold text: Use for job titles, company names, and section headings only
• Italics: Optional for company names or dates

How to Create a Resume That Passes ATS in 5 Steps

Here's my exact process for building an ATS-friendly resume from scratch:

Step 1: Start with an ATS-Friendly Template

Don't start with a blank document or a creative template from Canva. Use a simple Word document or a verified ATS-optimized template. This saves you from formatting mistakes later.

Step 2: Match Job Description Keywords

Before writing anything, analyze the job posting:

• Highlight skills mentioned 2+ times
• Note specific tools, software, or certifications listed
• Identify the required years of experience
• Pay attention to how they phrase responsibilities

Create a keyword list to reference as you write.

Step 3: Use Standard Formatting (See Section Above)

Follow the template structure exactly: Contact > Summary > Skills > Experience > Education > Certifications. Use standard fonts, simple bullets, no tables or graphics.

Step 4: Test with an ATS Scanner

Upload your resume to an ATS checker and review the parsed output:

• Is all information captured correctly?
• Are dates and company names in the right places?
• Did the skills section populate?
• Are there any errors or missing sections?

Fix any issues the scanner identifies, then test again.

Step 5: Have a Human Review It

This is critical: ATS is just the first filter. A human recruiter will read resumes that pass ATS screening. Make sure your resume:

• Tells a clear career story
• Highlights achievements, not just responsibilities
• Is free of typos and grammatical errors
• Demonstrates impact with numbers (increased revenue 30%, reduced costs by ₹5L)

An ATS-optimized resume that's boring or generic won't get you interviews. Balance ATS requirements with compelling content.

FAQ: ATS Resume Tips

Do all companies use ATS?

Approximately 98% of Fortune 500 companies use applicant tracking systems to manage job applications.[1] Among large companies, about 66% use ATS software.[2] The usage is most common in industries like technology, finance, healthcare, and professional services. Small businesses with fewer than 50 employees are less likely to use ATS, often reviewing applications manually instead.

Can ATS read PDF resumes?

Modern ATS software can read PDF resumes, but compatibility varies by system. Cloud-based ATS platforms like Greenhouse, Lever, and Workday handle PDFs well.[4] However, .docx format remains the safest choice with 99% compatibility across all systems.[5] Never submit image-based PDFs, scanned documents, or PDFs created from design software like Canva, as these are unreadable by ATS parsers.

How do I know if my resume passed ATS?

You cannot directly know if your resume passed an ATS without access to the company's system. However, indicators include receiving interview requests within 1-2 weeks of applying, getting automated emails confirming your application was reviewed, or being contacted by recruiters. To test before applying, use ATS resume scanners like ResumeBold's free checker, which simulates how major ATS platforms parse your resume and identifies formatting issues that could cause rejection.

Should I remove all formatting to pass ATS?

No, you should not remove all formatting. ATS systems can read standard formatting like bold text, bullet points, italics, and basic font styling. Use simple, clean formatting with standard fonts (Arial, Calibri, Times New Roman), clear section headings, and basic bullets. Avoid complex layouts like tables, text boxes, columns, headers/footers, and graphics. The goal is readable structure, not a plain text document.

What keywords should I include in my ATS resume?

Include keywords directly from the job description, focusing on hard skills, software tools, certifications, and industry-specific terms. For example, if the job lists "Python, SQL, data visualization, and Tableau," include those exact phrases in your skills section and work experience. Also include variations and acronyms (e.g., "Search Engine Optimization (SEO)" then "SEO" later). Avoid keyword stuffing; integrate 8-12 core keywords naturally throughout your resume in context of your actual experience.

How long should an ATS-friendly resume be?

One page for early career professionals (0-5 years experience), two pages for mid-career (5-15 years), and up to three pages for senior executives or academic positions. ATS systems have no page limit preference, but recruiters who review resumes after ATS screening prefer concise formats. Focus on relevance over length. Each position should have 3-5 bullet points highlighting quantifiable achievements and keyword-rich responsibilities.

3. Test with an ATS scanner before applying (catches issues you might miss)

Job searching is hard enough without worrying about whether your resume will even be seen. These tips give you confidence that your application makes it past the bots and into the hands of people who can hire you.
