How to Write an ATS-Friendly Resume in 2025 (Complete Guide)

An Applicant Tracking System (ATS) is software that companies use to collect, filter, and rank job applications automatically. Research from Jobscan shows that over 98% of Fortune 500 companies use ATS systems, and studies estimate that 75% of resumes are rejected before a recruiter ever reads them. Common platforms include Workday, Greenhouse, Lever, iCIMS, and Taleo. Each has slightly different parsing rules, but all share the same core vulnerability: they rely on keyword matching and structured formatting.

1. Tables and columns: ATS systems cannot parse multi-column layouts. Content inside table cells is often ignored entirely. 2. Headers and footers: Text placed in Word or PDF headers/footers is invisible to most parsers. Keep all key information in the main body. 3. Wrong file format: Always submit PDF unless the job posting specifically asks for DOCX. PDFs preserve formatting while remaining parseable. 4. Missing keywords: ATS software matches your resume against the job description. If critical skills from the JD are absent, your score drops. 5. Non-standard section titles: Use 'Work Experience' not 'Where I've Worked'. ATS expects conventional heading names. 6. Images and graphics: Logos, photos, and icon-based skill bars cannot be read. Remove all decorative graphics. 7. Font issues: Exotic fonts may not render correctly. Stick to Arial, Calibri, or Times New Roman.

Use a single-column layout for maximum compatibility. Structure your resume in this order: (1) Contact information at the top — name, email, phone, LinkedIn URL, location. (2) Professional summary — 3–4 sentences incorporating your target job title and top skills. (3) Work experience — reverse chronological, with company name, job title, dates, and 3–5 bullet points per role. (4) Education — degree, institution, graduation year. (5) Skills — a dedicated skills section with explicit keyword matches. Each bullet point should start with an action verb and include a measurable outcome where possible.

The most reliable method is to analyze the job description directly. Read it carefully and highlight: required skills (both technical and soft), specific tools or technologies, certifications mentioned, and role-specific verbs. Then compare these against your resume. Any gap is a potential rejection flag. Aim to include the top 10–15 keywords from the JD naturally throughout your resume — in your summary, work experience bullets, and skills section. Avoid keyword stuffing: ATS systems and human reviewers both penalize unnatural repetition.

Launch CV's ATS Score Checker simulates how 15+ major applicant tracking systems parse your resume. Upload your PDF or DOCX and receive an instant score from 0–100, broken into four categories: Formatting (detects tables, columns, images), Keywords (measures density vs. industry benchmarks), Structure (checks for expected sections), and Readability (length, date formats, contact info parsing). The average user improves their score by 43 points after addressing the flagged issues. High-priority fixes are shown first, with specific instructions for each problem.
