How to Write an ATS Friendly Resume in 2025

If your resume is disappearing into a black hole after every application, an Applicant Tracking System is almost certainly the reason — and in 2025, knowing how to write an ATS friendly resume is no longer optional, it is the price of entry to the modern job market.

Why ATS Optimization Matters More Than Ever in 2025

Applicant Tracking Systems have been around since the 1990s, but the technology has evolved at a staggering pace. Today, companies like Google, Amazon, Microsoft, and virtually every Fortune 500 employer route 100% of inbound applications through ATS platforms such as Workday, Greenhouse, Lever, iCIMS, and Taleo. According to research published by Harvard Business School, over 75% of resumes are rejected by ATS software before a human recruiter ever sees them. That number is not a scare statistic — it is a structural reality of the 2025 hiring process.

The good news is that ATS systems are not magic. They follow rules. They scan for specific keywords, parse document structure, and rank candidates against a job description. Once you understand those rules, you can write a resume that sails through automated screening and lands in a recruiter's inbox. This guide will walk you through every step, from document formatting to final proofreading, with concrete examples drawn from real job postings at companies you recognise.

Understanding How ATS Software Actually Works

Before you can beat the system, you need to understand it. An ATS does several things simultaneously when your resume arrives:

• Parsing: The software extracts text from your document and sorts it into fields — name, contact information, work history, education, and skills.
• Keyword matching: It compares your resume text against the job description, looking for exact or near-exact matches of required skills, job titles, and qualifications.
• Scoring: It assigns a relevance score, often expressed as a percentage, and ranks your application against every other candidate in the pool.
• Filtering: Applications below a threshold score are automatically rejected or deprioritised.

Modern ATS platforms, particularly those used by Amazon and Meta, now incorporate machine learning that goes beyond simple keyword counting. They assess semantic relevance, meaning that writing "people management" when a job description says "team leadership" may still score points. However, relying on semantic interpretation is risky. The safest strategy in 2025 remains mirroring the exact language of the job posting wherever truthful and relevant.

Choosing the Right File Format

This is the first and most common mistake job seekers make. A beautifully designed PDF might look spectacular on screen but can be completely unreadable to certain ATS parsers. Here is what you need to know:

• Use .docx as your default submission format unless the job posting explicitly requests a PDF. Microsoft Word documents are parsed most reliably across all major ATS platforms.
• PDFs are safer than they used to be — most modern ATS platforms handle standard PDFs well — but text-based PDFs only. Never submit a PDF that was created from a scanned image or contains graphics-heavy layouts.
• Avoid .pages, .odt, and Google Docs exports unless explicitly accepted. These formats introduce parsing errors in many systems.

If you are unsure which format to use, submit .docx for corporate roles at large employers like Deloitte, KPMG, or JPMorgan Chase, and check startup job boards carefully — many smaller companies using Lever or Ashby accept PDFs without issue.

The Golden Rules of ATS-Friendly Formatting

Formatting is where most visually appealing resumes fall apart technically. The core principle is simple: prioritise machine readability over visual flair. Here is how to apply that principle in practice.

Use a Clean, Single-Column Layout

Multi-column resumes, which look impressive in Canva or Adobe InDesign, confuse ATS parsers. The software reads left to right, top to bottom. When you split your resume into two columns, the parser often reads both columns simultaneously in a garbled sequence, destroying the logical flow of your experience. Stick to a single-column layout for any role at a large organisation. If you are applying to a creative agency or a design-led company like Shopify or Airbnb's design team, you may use a slightly richer layout — but still test it against an ATS checker first.

Choose Standard, Readable Fonts

Stick to fonts that every system recognises: Calibri, Arial, Garamond, Georgia, or Times New Roman. Font size should be 10–12pt for body text and 14–16pt for your name. Avoid decorative or script fonts entirely — they are parsed as images in many systems and your text simply disappears.

Use Standard Section Headings

ATS software is trained on millions of resumes. It knows to look for "Work Experience," "Education," and "Skills." When you rename sections creatively — "My Journey," "Where I've Been," or "Things I Know" — the parser cannot classify the content correctly, and your entire work history may be lost. Use these exact headings:

• Work Experience (or Professional Experience)
• Education
• Skills
• Certifications
• Summary (or Professional Summary)

Avoid Tables, Text Boxes, Headers, and Footers

Tables and text boxes are invisible to many parsers. If you store your contact information in a header or a table — as many Microsoft Word resume templates do — there is a real chance your phone number and email address never make it into the ATS database at all. Place all contact information in the main body of the document, as plain text beneath your name.

Similarly, avoid placing information in the document's header or footer sections. What displays at the top of your Word document in the header field is not the same as what you type in the body, and most ATS platforms skip header and footer content entirely.

Keyword Strategy: The Heart of ATS Optimisation

No single element of your resume affects your ATS score more than keywords. The strategy is straightforward but requires careful execution.

Start With the Job Description

Every job description is essentially a keyword map. Your job is to identify the most important terms and reflect them accurately in your resume. Look for:

• Hard skills: "Python," "SQL," "Salesforce," "financial modelling," "PPC campaign management"
• Soft skills (used specifically): "cross-functional collaboration," "stakeholder management," "agile methodology"
• Certifications and credentials: "PMP," "AWS Certified Solutions Architect," "CFA," "CIPD Level 5"
• Job title variations: If the posting says "Software Engineer" but your previous title was "Developer," include both

A practical approach is to paste the job description into a keyword analysis tool to surface the highest-frequency terms. You can extract job keywords automatically using our dedicated tool, which highlights the must-have phrases before you begin writing.

Integrate Keywords Naturally

Keyword stuffing — listing skills with no context, repeating a term five times in a row — is penalised by sophisticated ATS platforms and will alienate any human recruiter who does see your resume. Instead, weave keywords into achievement-based bullet points:

Wrong: "Python Python Python data analysis data analysis stakeholder management"
Right: "Developed automated data pipelines using Python and SQL, reducing report generation time by 40% and enabling real-time stakeholder dashboards."

That single bullet point includes "Python," "SQL," "data analysis" (implied), and "stakeholder" — all high-value keywords — within a compelling, quantified achievement.

Tailor Your Resume for Every Application

This is the advice job seekers most consistently ignore, and it is the most important. A generic resume sent to 200 companies will consistently score lower than a tailored resume sent to 20. When Microsoft posts a role for a "Senior Product Manager — Azure Marketplace," and Amazon posts a role for a "Senior Product Manager — AWS Partner Network," those are different keyword environments. The resume you send to each should reflect that difference, even if your underlying experience is identical.

Writing Each Section for Maximum ATS Impact

Professional Summary

Your summary sits at the top of your resume and is one of the first things an ATS parses. Use it to front-load your most important keywords. Write 3–4 sentences that capture your role, your years of experience, your core competencies, and a notable achievement. For a software engineering role at Stripe, you might write:

"Senior Software Engineer with 8 years of experience building high-availability distributed systems in Go and Python. Proven track record delivering payment infrastructure at scale, with expertise in microservices architecture, Kubernetes, and CI/CD pipeline optimisation. Previously led a team of six engineers to reduce API latency by 35% across Stripe's core checkout service."

That summary is dense with relevant keywords, grounded in real achievement, and immediately positions the candidate for the role.

Work Experience

List roles in reverse chronological order. For each role, include your job title, company name, location (city and country is sufficient), and dates (month and year). Use bullet points rather than paragraphs, and begin each bullet with a strong action verb: "Led," "Built," "Managed," "Reduced," "Increased," "Delivered," "Launched."

Quantify wherever possible. "Managed a team" is weak. "Managed a cross-functional team of 12 engineers and designers to deliver a $3M SaaS platform on schedule" is powerful — and keyword-rich.

Skills Section

The skills section deserves more strategic thought than most candidates give it. Group skills logically: technical skills separate from tools separate from languages. Do not pad this section with generic soft skills like "good communicator" — ATS systems have become increasingly sceptical of unverifiable claims. Focus on hard, specific skills that appear in job descriptions for your target roles.

When you are ready to put these principles into practice, you can build your free ATS resume using our structured builder, which guides you through each section and flags potential parsing issues in real time.

Education

List your highest degree first. Include the degree title, institution name, location, and graduation year. If you graduated recently (within the last three years), you may include relevant coursework, thesis topics, or academic projects. For experienced professionals, keep this section brief — a single line per qualification is usually sufficient.

For UK applicants: include A-levels or Scottish Highers if you are early in your career or if they are directly relevant. Australian applicants should note that ATAR scores are not standard on resumes and can be omitted. Canadian applicants follow broadly the same conventions as the US.

Certifications and Professional Development

In 2025, certifications are more valuable than ever as employers seek verifiable proof of skills. List certifications with their full official name, issuing body, and year of attainment. "AWS Certified Solutions Architect – Associate (Amazon Web Services, 2024)" is far more parseable — and credible — than just "AWS certification."

Common ATS Mistakes to Avoid in 2025

• Using graphics, icons, or logos — These are invisible to ATS and waste valuable space
• Submitting a photo — Especially important note for candidates transitioning from markets where photos are standard (Germany, France, parts of Asia): in the US, UK, Canada, and Australia, photos on resumes are not only unnecessary but can trigger bias concerns and confuse ATS parsers
• Using abbreviations without spelling them out — Write "Search Engine Optimisation (SEO)" the first time so the ATS picks up both forms
• Leaving unexplained employment gaps — ATS date-parsing algorithms flag long gaps; briefly address them with a short phrase like "Career break – professional development and freelance consulting (2023–2024)"
• Using a functional or skills-based resume format — ATS systems are optimised for chronological formats; functional resumes consistently score lower

Testing Your Resume Before You Submit

Never submit a resume you have not tested. Paste your resume text into a plain text editor like Notepad. If the result is garbled, full of strange characters, or loses its logical sequence, an ATS will have the same experience. Fix the formatting issues before you submit.

You can also run your resume through our ATS resume templates to compare your current layout against formats that are pre-validated for ATS compatibility. Each template in the library has been tested across Workday, Greenhouse, Lever, and Taleo.

Beyond formatting, use the job description keyword match rate as a quality benchmark. Aim for a match rate of at least 70–80% on your primary keywords before submitting. Anything below 60% means your resume needs significant tailoring for that specific role.

The Human Layer: What Happens After the ATS

Optimising for ATS is essential, but do not lose sight of the human recruiter who reads your resume once it clears the automated filter. The same qualities that make a resume ATS-friendly — clear structure, concrete achievements, specific language — also make it compelling to a human reader. The best resumes in 2025 serve both audiences simultaneously.

Once your resume lands in a recruiter's inbox at a company like Shopify, Apple, or Accenture, you have roughly six seconds of initial attention. Lead with your strongest achievement, use white space generously, and keep the document to one page for under ten years of experience, or two pages maximum for senior professionals. Three-page resumes are almost universally too long for any role below C-suite level.

Your resume is also the foundation of your cover letter. A strong, keyword-rich resume gives you the raw material for a compelling cover letter that reinforces rather than repeats your application narrative. If you need support with that next step, our AI cover letter generator can produce a tailored draft in minutes, pulling context directly from your resume content and the job description.

Regional Nuances for 2025

While the core principles of ATS optimisation are universal, a few regional differences are worth noting for international job seekers:

• United States: Do not include age, marital status, nationality, or a photo. Resume length norm is one page for early-career, two pages for experienced professionals.
• United Kingdom: The document is called a CV, not a resume, though the ATS formatting rules are identical. Two pages is the standard length. Include a personal statement rather than a summary. Spell-check for British English — "optimise" not "optimize," "organisation" not "organization."
• Canada: Follows US conventions closely. Bilingual candidates applying in Quebec should have French and English versions ready.
• Australia: CVs run slightly longer than US resumes — two to three pages is acceptable. Include a "Key Selection Criteria" section when applying for government roles, as Australian Public Service applications require it explicitly.

Conclusion

Writing an ATS friendly resume in 2025 comes down to four pillars: clean, single-column formatting that parsers can read without errors; strategic keyword integration drawn directly from each job description; achievement-focused content that quantifies your impact; and consistent testing before every submission. The job market is competitive, but the ATS filter is a solvable problem — once you understand the rules, you can write to them without sacrificing the quality of your narrative. Apply these principles consistently, tailor every application, and you will spend far less time wondering why your resume never gets a response and far more time preparing for interviews.
