Getting Started with the ATS Checker
Learn how to use our ATS optimizer to scan your resume against job descriptions and improve your interview chances.
What is an ATS?
An Applicant Tracking System (ATS) is software that parses resumes into structured data and ranks candidates against job requirements before a human sees them. Over 99% of Fortune 500 companies and 75% of mid-size employers use some form of ATS screening.
The critical insight: ATS systems don't read resumes like humans. They extract text by scanning for section headers, then match keywords from the job description against your experience. If your resume format confuses the parser, your qualifications never make it into the database.
How Our ATS Checker Works
Our ATS Checker evaluates your resume against a target job description and returns a score with specific improvement recommendations.
Step 1: Import Your Resume
Paste your resume text or upload a PDF/DOCX. The checker parses the content the same way an employer's ATS would, so you see exactly what a recruiter's system sees.
Step 2: Paste the Job Description
The more complete the job description, the more accurate the match analysis. Include the full posting — required qualifications, preferred skills, responsibilities, and even nice-to-haves.
Step 3: Run Analysis
The AI compares your resume against the job requirements using four dimensions:
| Dimension | What It Measures | |-----------|-----------------| | Keyword Match | Percentage of job description terms present in your resume | | Skill Alignment | How your listed skills overlap with required and preferred skills | | Experience Relevance | Whether your job history patterns match the role's seniority level | | Format Compatibility | Whether your layout is parseable by standard ATS engines |
Step 4: Act on Recommendations
Each score comes with prioritized actions: add missing keywords, rewrite unclear bullets, restructure sections, or fix formatting issues. Apply the changes and re-scan until your score passes 80%.
Tips for a Higher Score
Use Standard Section Headings
ATS parsers look for these exact headers: "Work Experience," "Education," "Skills," "Certifications," "Summary." Creative headings like "Where I've Worked" or "My Toolbox" are often skipped entirely.
Weave Keywords Into Context
Listing "Python, AWS, Kubernetes" in a skills column is weak. Embed each term in a bullet point instead: "Designed a Kubernetes deployment pipeline on AWS that reduced deploy time from 45 minutes to 4 minutes." This satisfies both the keyword scanner and the human recruiter.
Avoid Tables, Columns, and Graphics
Multi-column layouts cause parsers to read across columns, jumbling your experience. Text boxes and graphics are invisible to most ATS engines. A single-column, no-table layout is the safest.
Submit in the Right Format
DOCX is the most universally parseable format. PDF is also widely supported, but some older ATS systems mangle it. If the application offers both, choose DOCX. Never submit a scanned image of your resume — it cannot be parsed at all.
