How to Optimize Your Resume for ATS in 2026

In 2026, over 98% of Fortune 500 companies — and a growing number of smaller businesses — use Applicant Tracking Systems to filter resumes. If your resume isn't optimized for ATS, it may never reach a human recruiter, regardless of how qualified you are.

This guide gives you a practical, step-by-step plan to boost your ATS score and get more interview calls.

Understanding Your ATS Score

ATS scores are typically calculated based on five main factors. Knowing these helps you prioritize where to focus your effort:

1. Keyword Strategy (30% of Score)

Keywords are the single most important factor in ATS scoring. ATS systems literally compare your resume words against the job description and count matches.

How to find the right keywords

• Read the job description carefully — list every skill, tool, and qualification mentioned
• Pay attention to the exact phrasing used (e.g., "project management" vs "managing projects")
• Include both the abbreviation and the full form (e.g., "SEO (Search Engine Optimization)")
• Look at 5–10 similar job postings to identify common patterns
• Use tools like LinkedIn, Glassdoor job descriptions as keyword sources

2. ATS-Safe Formatting (20% of Score)

Beautiful resume designs often perform terribly in ATS. The safest formats are the simplest ones.

Formatting rules to follow

• Use a single-column layout — avoid two-column or multi-column designs
• Avoid tables, text boxes, and frames
• Don't embed images, logos, or icons
• Remove headers and footers — put contact info in the main body
• Use standard, readable fonts (Calibri, Arial, Georgia, Times New Roman)
• Font size: 10–12pt for body, 14–16pt for headings
• Use consistent bullet points (•) — avoid decorative symbols (★, ✦, ➡)
• Leave adequate white space — don't crowd the document

3. Required Resume Sections (20% of Score)

ATS systems look for specific section headers to understand your resume structure. Missing or mislabeled sections result in lower scores.

Essential sections to include

• Contact Information — Name, phone, email, LinkedIn, city/state (no full address needed)
• Professional Summary — 3–5 lines tailored to the specific role
• Skills — A dedicated section with relevant technical and soft skills
• Work Experience — Listed in reverse chronological order with quantified achievements
• Education — Degrees, institutions, graduation years
• Certifications (if relevant) — Especially important in technical roles

4. Choosing the Right File Format (15% of Score)

Not all file formats are created equal when it comes to ATS compatibility.

• DOCX (Best): Microsoft Word format is the most universally compatible with all ATS platforms. Always prefer this format unless the application explicitly asks for PDF.
• PDF (Good, with caveats): Text-based PDFs work reasonably well, but ensure you saved it from Word or Google Docs — not a design tool.
• Avoid: Scanned PDFs, image-based files, .pages, .odt, or design tool exports from Canva/Figma

Test your PDF

Open your PDF, select all text (Ctrl+A), and try to copy it. If you can copy readable text, the ATS will likely be able to parse it. If you can't, it's probably image-based and needs to be recreated.

5. Readability & Action Verbs (15% of Score)

ATS systems also evaluate how well-written your resume is. This includes sentence structure, use of action verbs, and quantified achievements.

Power verbs that boost ATS scores

• Leadership: Led, Managed, Directed, Spearheaded, Oversaw, Coordinated
• Achievement: Achieved, Delivered, Exceeded, Improved, Increased, Generated
• Creation: Developed, Designed, Built, Created, Launched, Established
• Analysis: Analyzed, Evaluated, Assessed, Identified, Researched, Monitored
• Communication: Presented, Negotiated, Collaborated, Facilitated, Advised
