What is an ATS resume checker?

An ATS (Applicant Tracking System) resume checker analyzes your resume to determine how well it will perform when scanned by hiring software used by 99% of Fortune 500 companies. It identifies missing keywords, formatting issues, and provides a compatibility score to help you optimize your resume and get past automated screening.

Is ATSOptimization free?

ATSOptimization offers a free ATS score check with no signup required. You can see your compatibility score and how many keywords are missing or matched. Pro users unlock the full details - seeing exactly which keywords to add, what formatting issues to fix, and get AI-powered automatic optimization. Pro starts at $14.90/month.

How do I make my resume ATS-friendly?

To make your resume ATS-friendly: 1) Use standard section headers like "Experience" and "Education", 2) Include relevant keywords from the job description, 3) Avoid tables, graphics, and complex formatting, 4) Use simple bullet points, 5) Save as PDF or DOCX. ATSOptimization automatically checks for all these issues and provides AI-powered suggestions.

Which ATS systems does ATSOptimization work with?

ATSOptimization is tested and optimized for all major ATS platforms including Workday, Taleo, Greenhouse, Lever, iCIMS, BambooHR, SAP SuccessFactors, ADP, and more. Our AI algorithm is continuously updated as these systems evolve to ensure maximum compatibility.

How quickly will I get more interviews after optimizing my resume?

Most users report a significant increase in interview callbacks within the first week of applying with their optimized resume. Based on data from 2.5 million optimized resumes, users see an average 89% increase in interview rates after using ATSOptimization.

Why is my resume getting rejected?

Your resume is likely getting rejected because: 1) Missing keywords that ATS systems scan for, 2) Formatting issues like tables or special characters that ATS cannot parse, 3) No quantified achievements or metrics. Use ATSOptimization to identify exactly what's wrong and get AI-powered fixes.
