Essential Formatting Strategies
Proper formatting is crucial for ATS compatibility. Here are the key strategies:
Stick to standard, single-column layouts without complex graphics, tables, or unusual design elements.

Using complex tables, text boxes, or graphics that ATS cannot parse properly.
Use standard, professional fonts that are easily readable by ATS systems:
- Best choices: Arial, Calibri, Times New Roman, Georgia
- Avoid: Fancy fonts, script fonts, or custom fonts
- Size: Use 10-12pt font size for optimal readability
Proper spacing ensures your resume is readable by both ATS and humans:
- Use 0.5-1 inch margins on all sides
- Add space between sections for clarity
- Avoid cramming too much information
Keyword Optimization Techniques
Keywords are critical for ATS success. Here's how to optimize them effectively:
Use the exact terminology from the job posting. If they say "project management," don't write "project coordination."
Job posting says: "Experience with JavaScript frameworks"
Your resume should say: "Developed applications using JavaScript frameworks including React and Vue.js"
Research and include relevant industry terms, certifications, and technical skills:
- Technical skills (programming languages, software, tools)
- Industry certifications (PMP, CPA, AWS Certified)
- Soft skills mentioned in the job description
- Action verbs relevant to your field
Standard Section Headers
Use conventional section headers that ATS systems recognize:
- • Contact Information
- • Professional Summary
- • Work Experience
- • Education
- • Skills
- • Certifications
- • About Me
- • My Journey
- • What I've Done
- • Learning
- • Superpowers
- • Credentials
Best File Formats for ATS
Choose the right file format to ensure ATS compatibility:
- .docx: Most universally compatible with modern ATS
- .pdf: Good for preserving formatting, but test first
- .txt: 100% ATS compatible but loses all formatting
Pro tip: When in doubt, submit in .docx format unless the job posting specifically requests PDF.
Common ATS Mistakes to Avoid
Many ATS cannot read information in headers and footers. Keep all important information in the main body.
ATS cannot parse images, logos, or charts. Stick to plain text for all content.
Multi-column layouts and text boxes can confuse ATS parsing. Use a single-column format.
Avoid special characters and symbols. Use standard bullets (•) instead of fancy symbols.
