What ATS Systems Look For in Your Resume
Applicant Tracking Systems (ATS) automatically scan, parse, and rank your resume before a human recruiter ever sees it. Understanding what these systems look for can dramatically improve your chances of getting an interview. Our ATS resume checker analyzes five critical areas that determine your ATS compatibility.
Formatting
ATS systems work best with single-column layouts. Complex designs, tables, headers/footers, and text boxes can cause parsing errors. Use standard fonts and clear section headings.
Keyword Match
ATS systems match your resume against the job description keywords. Include specific tools, technologies, certifications, and industry terminology from the job posting.
Section Completeness
ATS systems expect standard sections: Contact Info, Summary, Experience, Education, and Skills. Missing sections reduce your score and may cause the ATS to skip important data.
Contact Information
Complete contact details help ATS systems index your resume. Include email, phone number, location, and LinkedIn profile. Place contact info at the top of the document.
Readability
Clear, well-structured content with bullet points and concise descriptions scores higher. Avoid long paragraphs, dense text blocks, and unusual formatting that ATS parsers may misinterpret.

To make your resume ATS-friendly: use a single-column layout, include standard section headers (Experience, Education, Skills), use industry-specific keywords from the job description, avoid tables and graphics, use bullet points, and save as PDF or DOCX format.
