How to Check Your Resume for ATS Compatibility

An applicant tracking system (ATS) reads your resume as text. If something in the file does not survive the conversion to text, the system never sees it, and neither does the recruiter who searches it. To check your resume for ATS problems, you do not need special software. Three checks cover it.

1. Paste it into a plain text editor

Open your resume, select everything, copy, and paste into Notepad, TextEdit in plain-text mode, or any editor with no formatting. Then read what arrived.

You are looking for three things:

• Sections in the wrong order, or text from two columns interleaved line by line.
• Missing content: a skills block, a phone number, or dates that lived in a text box, header, or footer.
• Broken characters where bullets, icons, or special dashes were.

If a person cannot tell what you do from the pasted text, a parser cannot either. This one test finds most real parsing failures.

2. Review the layout

Parsers are built for ordinary documents. Layouts that work:

• One column, top to bottom.
• Standard section headings — Experience, Education, Skills — rather than inventive ones.
• Job title, employer, and dates on predictable lines.
• A text-based PDF or a .docx. A PDF exported from a design tool as flattened images has no text to read.

Layouts that cause trouble: multi-column designs, tables used for positioning, skill ratings drawn as bars or dots, and anything placed in a header or footer. Contact details in a header are a common casualty.

3. Compare it with the posting

Readable is the first requirement. The second is relevance: the posting names the tools, methods, and titles the employer is looking for, and a recruiter searching or filtering a pile of applications searches for those words.

Read the posting and list the concrete terms — specific tools, certifications, methods, the job title itself. Search your resume for each one. A term you have real experience with but never wrote, or wrote in different words, is a gap to close. A term you do not have stays out.

This comparison is what an ATS resume checker automates: it reads the posting you give it, compares it with your resume, and lists what matched and what is missing. FitCV runs it as a free check in a side panel next to the posting. For how to read the result, see what a resume score means.

Questions

How do I check my resume for ATS without a tool?

Run the plain-text paste, review the layout against the list above, then search your resume for the terms in the posting. That covers readability and relevance.

Is a PDF or a Word file better for an ATS?

Either works when it contains real text. Use the format the application asks for. If it does not say, a text-based PDF or a .docx is fine; confirm with the plain-text paste.

What does an ATS resume checker show?

Which terms from the posting your resume already contains, which it lacks, and whether the document parses cleanly. The missing terms are the part to act on.

Do I need a different resume for every posting?

The facts stay the same; the emphasis changes. Put the posting’s relevant terms where they are true. The step-by-step way to do this is short.
