What Is ATS Resume Optimization?
ATS Resume Optimization is the process of restructuring and rewriting your resume so it scores highly when parsed by an Applicant Tracking System (ATS) — the software that 98% of large employers use to automatically filter job applications before a human recruiter ever sees them.
How Does an ATS Read Your Resume?
An ATS parses your resume into structured data — name, skills, work history, education — then scores it against keywords and requirements from the job posting. Resumes that don't match the expected format or lack key terms are automatically filtered out.
What Is a Resume Match Score?
A Resume Match Score is a percentage (0–100%) that shows how well your resume's content aligns with a specific job description. Scores below 60% are typically filtered out automatically. JD2CV targets 80–95% match scores.
Why Resume Keyword Optimization Matters
Missing even 5–8 critical terms from the job description can drop your match score below the recruiter's threshold. JD2CV's Resume Keyword Optimization engine identifies every required term and integrates them naturally.
