Applicant tracking systems (ATS) are used by most companies today to screen out resumes before a human recruiter even looks at them. For job seekers, an ATS resume scanner and optimizer is essential for getting your application seen and increasing your chances of landing interviews. This guide explains how these tools work, what makes an ATS-optimized resume, and which solutions—including CraftedCV—truly deliver results.
What Is an ATS Resume Scanner and Optimizer?
An ATS resume scanner and optimizer is software that reviews your resume and compares it to a job description, analyzing for relevant keywords, formatting, and alignment with job requirements. The goal: to make sure your resume passes automated screenings used by employers.
- ATS Scanners: Automatically read, parse, and filter resumes based on criteria set by employers.
- Optimizers: Help rewrite, format, and restructure your resume for better alignment with ATS algorithms and job descriptions.
- AI-Powered Matching: Leading tools leverage artificial intelligence to identify gaps, recommend fixes, and highlight the right keywords.
How ATS Resume Scanners Work
Applicant tracking systems start by parsing your resume into sections (experience, skills, education) and searching for job-specific terms. They match your information against predefined requirements from the employer’s posting, often assigning a relevance score.
Key Features of ATS Scanners
- Keyword Extraction: Scans for keywords from the job description and checks if your resume includes them.
- Formatting Checks: Evaluates layout, heading labels, fonts, and section order to confirm compatibility.
- Relevance Scoring: Assigns a score based on keyword matches, skills, and alignment between your resume content and the job requirements.
- Section Mapping: Maps your experience to essential categories (work history, education, skills, etc.).
- Feedback Reports: Provides recommendations for missing or weak areas.

Why ATS Optimization Matters
Roughly 75% of resumes never reach a recruiter—it’s the ATS making the initial cut. Many strong candidates are overlooked due to missing keywords, incompatible formats, or lack of alignment with the posted job description.
- Keyword Gaps: Failing to include core skills or role-specific terms means your resume could be filtered out.
- Formatting Errors: Resumes with unusual columns, graphics, or fonts may not be parsed correctly.
- Generic Applications: One-size-fits-all resumes rarely feature enough targeted content to score highly.
