What is an ATS resume checker and how does it work?

An ATS (Applicant Tracking System) resume checker analyzes your resume against the criteria that automated hiring software uses to filter candidates. It checks keyword matching, formatting compatibility, section detection, and overall structure. Our free ATS checker shows you a score and exactly what to fix.

Is my resume ATS-friendly if it uses a PDF format?

PDF resumes are generally ATS-compatible, but only if they contain selectable text (not scanned images). Avoid PDF resumes that use tables, columns, text boxes, or graphics — these cause ATS parsing failures even in text-based PDFs. A simple single-column PDF with clear section headers is the safest format.

What keywords should I add to pass ATS screening?

To pass ATS screening, copy keywords directly from the job description and include them naturally in your resume. Focus on: exact job title matches, required skills listed in the posting, industry-standard tool names (e.g. Salesforce, Python, AWS), and certification names. Paste the job description into our ATS checker to see exactly which keywords you're missing.

Why do I keep applying to jobs and not hearing back?

The most common reason is ATS rejection before a human reads your resume. Studies show 75% of resumes are rejected by ATS systems before reaching a hiring manager. Common causes: wrong keywords, incompatible formatting (tables, columns, graphics), missing section headers, or file type issues. Use our free ATS checker to diagnose the problem in under 10 seconds.

How is this free ATS checker different from paid resume tools?

Our free ATS resume checker does everything paid tools charge for: keyword matching, formatting analysis, section detection, and an ATS compatibility score — all with zero cost and no account required. Paid tools like Jobscan charge $49/month for the same analysis. We believe job seekers shouldn't pay to compete.
