What is an ATS?
An Applicant Tracking System (ATS) is software used by employers to collect, sort, scan, and rank job applications. Over 98% of Fortune 500 companies use an ATS, and about 75% of all companies use some form of applicant tracking.
When you submit your resume online, it typically goes through an ATS before a human ever sees it. The system scans your resume for relevant keywords, skills, and qualifications that match the job description.
Why ATS Optimization Matters
Studies show that up to 75% of resumes are rejected by ATS before they ever reach a hiring manager. This means that even highly qualified candidates can be filtered out simply because their resume isn't formatted correctly or doesn't contain the right keywords.
"The best resume in the world won't help you if it never gets seen by a human. ATS optimization is no longer optional—it's essential."
Formatting Tips for ATS Success
Here are the key formatting guidelines to follow:
- Use a simple, clean layout - Avoid tables, columns, headers, footers, and text boxes
- Stick to standard fonts - Arial, Calibri, Times New Roman, or Helvetica work best
- Use standard section headings - "Work Experience," "Education," "Skills" are universally recognized
- Save as .docx or PDF - These formats are most compatible with ATS systems
- Avoid graphics and images - ATS cannot read visual elements
Using the Right Keywords
Keywords are the foundation of ATS optimization. The system looks for specific terms that match the job description. Here's how to identify and use them effectively:
- Carefully read the job description and highlight key skills, qualifications, and requirements
- Include exact phrases from the job posting when they apply to your experience
- Use both spelled-out terms and acronyms (e.g., "Search Engine Optimization (SEO)")
- Incorporate industry-specific terminology naturally throughout your resume
Common Mistakes to Avoid
Even experienced professionals make these ATS-killing mistakes:
- Using creative file names - Stick to "FirstName_LastName_Resume.pdf"
- Submitting image-based PDFs - Always use text-based documents
- Keyword stuffing - This can flag your resume as spam
- Using uncommon section titles - "Career Journey" instead of "Work Experience"
- Including information in headers/footers - ATS often can't read these areas
Testing Your Resume
Before submitting your resume, test it to ensure ATS compatibility:
- Copy and paste your resume into a plain text document - if it's readable, it's likely ATS-friendly
- Use our free ATS Resume Checker tool to scan your resume
- Compare your resume against the job description to ensure keyword alignment
