The Complete ATS Resume Guide
Most resumes are rejected by software before a human ever sees them. This guide explains exactly how ATS works and how to make sure your resume gets through.
Test My Resume Against ATSWhat is an ATS?
An Applicant Tracking System (ATS) is software that employers use to manage job applications. It parses your resume, extracts key information, and ranks candidates based on how well their profiles match the job requirements — before a recruiter ever looks.
Research shows that 75% of resumes are rejected by ATS before reaching a human. The reasons are usually fixable: poor formatting, missing keywords, or incorrect file types.
ATS formatting rules
Use a single-column layout
Multi-column formats confuse most ATS parsers. They read left-to-right, top-to-bottom in a single flow.
Avoid tables and text boxes
Content inside tables or text boxes is often completely invisible to ATS software.
Use standard section headings
Stick to 'Experience', 'Education', 'Skills' — creative alternatives like 'My Journey' won't be recognized.
Save as DOCX or simple PDF
DOCX parses most reliably. PDFs work if they're text-based, not scanned images.
Skip headers and footers
Contact info in headers or footers is often lost. Keep everything in the main body.
Use standard fonts
Arial, Calibri, Times New Roman. Decorative fonts may render as garbled text.
Keyword strategy
ATS systems rank candidates by matching keywords from your resume against the job description. Here's how to optimize:
- Read the job description carefully and note repeated phrases and required skills
- Mirror the exact wording used — 'project management' vs. 'managing projects' may score differently
- Include both the spelled-out version and the acronym (e.g., 'Search Engine Optimization (SEO)')
- Don't keyword stuff — context matters; work keywords naturally into your bullet points
- Add a dedicated Skills section for technical tools and competencies
Common ATS mistakes
Frequently asked questions
What percentage of resumes are rejected by ATS?
Research consistently shows that 75% of resumes never reach a human recruiter because they're filtered out by ATS software first. The most common reasons are poor formatting, missing keywords, and incorrect file formats — all of which are fixable.
What file format is best for ATS?
DOCX (Microsoft Word) parses most reliably across all ATS platforms. A simple, text-based PDF also works well with modern systems. Avoid image-based PDFs, scanned documents, and creative formats from tools like Canva — these are often completely unreadable by ATS software.
Do all companies use ATS software?
Most medium and large employers do. Studies estimate that over 98% of Fortune 500 companies use ATS to manage applications. Smaller companies and startups may still review resumes manually, but optimizing for ATS never hurts — a clean, keyword-rich resume reads better for humans too.
Can a PDF resume pass ATS?
Yes, if it's a text-based PDF (not a scanned image). When you save a Word document as PDF, the text remains machine-readable. Problems arise with PDFs created from design tools that embed text as images or use non-standard encoding. When in doubt, test your PDF with our ATS checker.
How do I know if my resume passed ATS?
If you've applied to many jobs and heard nothing back, ATS filtering is a likely culprit. The clearest signal is uploading your resume to an ATS checker tool like BetterSkilled's — you'll see exactly how your resume parses, which sections are detected, and which keywords are missing.
Should I use a resume template for ATS?
Yes, but choose carefully. Most design-heavy templates from Canva, Etsy, or PowerPoint fail ATS because they use tables, text boxes, and images. Use a simple, single-column template designed specifically for ATS compatibility — or start from a plain Word document.
