Tips for Better ATS Resume Score

1. Use Keywords from the Job Description

ATS systems scan for specific keywords. Include job-relevant terms throughout your resume. KUPOSU AI does this automatically by analyzing each job posting.

2. Keep Formatting Simple

Avoid tables, columns, images, and fancy graphics. Use a clean, single-column layout that ATS can easily parse.

3. Use Standard Section Headings

Stick to conventional headings like "Work Experience," "Education," and "Skills." Creative headings may confuse ATS systems.

4. Include Both Acronyms and Full Terms

Write "Search Engine Optimization (SEO)" instead of just "SEO" to ensure ATS catches both versions.

5. Tailor Your Resume for Each Job

Generic resumes get low ATS scores. Customize your resume for each application - or let KUPOSU AI do it for you automatically.

6. Submit in the Right Format

Most ATS systems work best with .docx or .pdf files. KUPOSU AI generates perfectly formatted PDFs that are guaranteed to be ATS-compatible.
