Why Your Resume Gets Rejected by ATS

Applicant Tracking Systems like Workday, Taleo, Greenhouse, and iCIMS automatically filter resumes before recruiters see them. Three of the most common reasons:

🔍

Missing Keywords

ATS software scans for specific keywords from the job description. Missing them often means automatic rejection — even when you are qualified.

⚠️

Bad Formatting

Tables, columns, fancy bullets, smart quotes, and special characters break ATS parsing. Your resume becomes unreadable to the system.

📊

No Quantified Results

Vague achievements get low scores. ATS and recruiters favor specific metrics: percentages, dollar amounts, team sizes, scope.

Frequently Asked Questions

What is an ATS (Applicant Tracking System)?

An Applicant Tracking System is software employers use to manage job applications. It automatically scans, parses, and ranks resumes based on keywords and formatting before a recruiter ever sees them. Common ATS platforms include Workday, Taleo, Greenhouse, Lever, and iCIMS.

Why do I need an ATS resume checker?

About 75% of resumes are filtered out by ATS software before they reach a human reviewer. An ATS checker shows you which keywords are missing and which formatting issues are silently breaking your resume in the parser, so you can fix them before applying.

Is ATSOptimization free?

Yes. The free tier gives you one resume analysis per browser, including your ATS score and match counts. Pro plans starting at $14.90/month unlock unlimited analyses, full visibility into which keywords are missing, AI-powered rewriting, and Precision and Stretch optimization modes.

How accurate is the ATS score?

Our scoring is based on how real ATS systems analyze resumes — keyword matching, formatting compatibility, and content structure. While no tool can guarantee 100% accuracy across every ATS, our checker reliably surfaces the most common issues that cause auto-rejection.

What file formats work with your ATS checker?

Paste your resume as plain text directly into the tool. When you submit your resume to a job, save the optimized version as a PDF or DOCX — both are widely supported by ATS platforms.
