In today's competitive job market, your resume needs to impress two audiences: the Applicant Tracking System (ATS) and the human recruiter. With 97.4% of Fortune 500 companies using ATS to screen candidates, understanding how to optimize your resume for these systems is no longer optional—it's essential.
What is an ATS and Why Does it Matter?
An Applicant Tracking System is software that companies use to collect, sort, scan, and rank job applications. Before your resume ever reaches human eyes, it must pass through this digital gatekeeper. According to recent studies, up to 75% of resumes are rejected by ATS before a recruiter ever sees them.
Essential ATS Optimization Strategies
1. Use a Clean, Single-Column Format
ATS systems parse resumes from top to bottom, left to right. Complex layouts with multiple columns, text boxes, or tables can confuse the parser and cause important information to be missed or scrambled.
- Stick to a single-column layout with clear section headings
- Use standard fonts like Arial, Calibri, or Times New Roman
- Avoid headers and footers—place contact info in the main body
- Save as PDF or DOCX (check if the employer specifies a preference)
2. Mirror Keywords from the Job Description
According to Jobscan's State of the Job Search 2025 report, 99.7% of recruiters use keyword filters in their ATS to sort and prioritize applicants. This means using the exact terminology from job postings is crucial.
3. Use Standard Section Headings
ATS systems are programmed to look for standard resume sections. Using creative headings like "Where I've Worked" instead of "Work Experience" can cause the system to miss critical information.
Stick to these standard headings:
- Professional Summary (or Summary)
- Work Experience (or Professional Experience)
- Education
- Skills
- Certifications (if applicable)
4. Aim for 75%+ Keyword Match
Career experts recommend achieving at least a 75% keyword match between your resume and the job description. Our AI-powered analysis tool can help you identify missing keywords and optimize your resume accordingly.
5. Quantify Your Achievements
While keywords get you past the ATS, quantified achievements impress the human recruiter. Use the Context-Action-Result format:
- Context: What was the situation?
- Action: What did you do?
- Result: What was the measurable outcome?
The Two-Resume Strategy
Smart job seekers in 2025 keep two versions of their resume:
- ATS-Optimized Version: Clean, keyword-rich, single-column format for online applications
- Visually Polished Version: A more designed version for networking, career fairs, and direct recruiter contact
