ATS Resume Checker: 10 Things to Fix Before You Apply
You spent hours on your resume, the job is a perfect fit, and still silence. In most cases the first reader wasn't a recruiter. It was an applicant tracking system that parsed your resume, scored it against the job description, and quietly ranked you below other candidates.
The good news: the reasons a resume fails an ATS are easy to find and fix. Run this check before your next application.
The ten-point check
- Submit a text-based PDF. A text PDF parses cleanly in almost every system. Avoid image files (scans, photos) and DOCX unless the posting asks for it.
- Use standard section headings. "Experience", "Education", "Skills", "Summary" are what parsers look for. Creative names like "My Journey" often get dropped.
- Mirror the job description's keywords. If the posting says "REST API" and "project management", use those exact terms where they're true for you. See the resume keywords guide.
- Write dates as MM/YYYY. "Sep 2022 – Mar 2024" parses reliably. Unusual date formats are a common failure.
- No tables, columns, text boxes, or graphics. Parsers flatten the page and these scramble the reading order. One clean column wins.
- Put contact details at the top. Name, phone, email, city, and LinkedIn in the first section, where the parser expects them.
- Quantify your bullets. "Reduced response time by 30%" beats "responsible for improving response time". Numbers help both ATS scoring and human recruiters.
- Skip photos, icons, and special characters. They add no parsing value and can break extraction on older systems.
- Keep it to one or two pages. Length rarely fails an ATS, but a shorter resume has fewer chances for formatting mistakes.
- Re-read it as a machine. If you'd struggle to extract the facts from your own resume, the parser will too. When in doubt, get an independent review before you rewrite.
After the check: what's on the resume
Formatting gets you through the door. What the ATS scores next is substance: whether your experience, skills, and achievements match the role. If your resume parses cleanly but still gets no responses, the problem is usually the content. Which sections are weak, which achievements are buried, whether your skills match the role's language.
