An ATS cannot rank what it cannot read. Formatting problems are among the most avoidable reasons a resume is misread, and most of them can be fixed in minutes.
1. Use one column
Tables, sidebars and text boxes can make a parser read content in the wrong order, so a job title ends up next to the wrong employer. A single column read top to bottom is the safest layout.
2. Use standard headings
Use plain headings such as Summary, Experience, Skills, Education and Certifications. Creative headings make it harder for a parser to decide which section a line belongs to.
3. Put contact details in the body
Some parsers ignore page headers and footers. Place your name, email, phone number, city and profile link at the top of the main page text.
4. Keep dates consistent
Use one format throughout, for example 'Jan 2022 - Present'. Consistent dates help a parser calculate your experience and spot gaps correctly.
5. Choose a safe file and fonts
A text-based PDF or a DOCX file works for most employers. Follow the instructions in the job posting if they name a format. Avoid scanned images of a resume, and use common fonts at a readable size.
6. Spell out tools and acronyms once
Write 'Search Engine Optimization (SEO)' or 'Continuous Integration (CI)' the first time, so the resume matches both the long and short forms used in postings.
Test it
Run your resume through the free ResumeChecker analyzer. It flags missing contact details, undetectable sections and extraction problems so you can fix them before you apply. No tool can guarantee how every employer's system behaves, so treat this as a way to remove common risks.
Checklist
• Single column, no tables or text boxes. • Standard section headings. • Contact details in the page body. • One consistent date format. • Text-based PDF or DOCX, common fonts.
