An ATS resume checker is a tool that analyzes how your resume will perform when scanned by applicant tracking systems. It checks for keyword matches between your resume and the job posting, evaluates formatting compatibility, and gives you a score indicating your chances of passing automated screening filters used by employers.
An ATS score of 80 or above is considered strong and means your resume is likely to pass most applicant tracking system filters. Scores between 60-79 indicate decent compatibility with room for improvement. Below 60 means significant keyword gaps that could cause your resume to be filtered out before a human recruiter ever reads it.
To make an ATS-friendly resume: use exact keywords from the job description, use standard section headers like Professional Experience and Education, use a single-column layout, avoid tables and graphics, use standard fonts like Arial or Calibri, and save as .docx or PDF format. Most importantly, tailor your resume for each specific job application.
Yes. Resume Weapon's ATS resume checker and AI resume builder are completely free to use. Upload your resume, paste any job posting, and instantly see your ATS compatibility score with matched and missing keywords. The AI-generated resume preview is free. You only pay if you want to download the clean version without watermarks ($4.99 per resume or $9.99/month unlimited).
Resumes get rejected by applicant tracking systems for three main reasons: missing keywords from the job description, formatting issues like tables, columns, text boxes, or graphics that confuse the ATS parser, and incompatible file types. The most common reason is simply not using the same terminology as the job posting.
Resume Weapon's ATS score extracts keywords, skills, tools, certifications, and requirements from the job description, then checks which ones appear in your resume. Multi-word skill phrases are weighted more heavily than single words since they indicate more specific matches. The score ranges from 0-100, with 80+ indicating strong alignment with the job requirements.
