FAQ
An ATS resume checker analyzes your resume against a job description and scores how well it matches. It identifies missing keywords and other factors that cause ATS software to filter out your application before a recruiter ever reads it.
Most ATS rejections happen because the resume is missing exact keywords from the job description, uses incompatible formatting (tables, columns, headers/footers), or lacks measurable achievements. ATS Optimizer scans your resume and tells you precisely what's causing the mismatch.
Mirror the exact language and keywords from the job posting, use a clean single-column layout, quantify achievements with numbers, and avoid graphics or text boxes. ATS Optimizer shows you the missing keywords and rewrites your bullets using the job description's language.
Yes. The free plan includes 3 ATS resume scans per month with full keyword analysis and match scoring. The Job Seeker Pack ($4.99 one-time) gives you 5 scans, 5 AI resume rewrites, and 3 cover letters — credits never expire.
ATS Optimizer uses Claude AI to perform keyword density analysis, semantic matching, and role-alignment scoring — the same signals real ATS systems prioritize. While every employer's ATS is configured differently, the score is a reliable indicator of resume-to-job fit.
