How to Check If Your Resume Is ATS Friendly Before Applying

What Is an ATS and Why Does It Matter?

ATS software is used by most companies to handle thousands of applications. It scans resumes for keywords, format, and relevant information that matches the job description. If your resume is heavy on graphics or complex layouts, the ATS might misread parts of it, or worse, skip those sections entirely.

So the main job here is simple: make your resume easy for the system to read and understand, without losing the impact for the recruiters who’ll read it later.

Step 1: Choose the Right Resume Format

Don’t shoot yourself in the foot by picking the wrong format. Fancy designs with tables, columns, or images? Big no-no. Those elements can throw off an ATS parser.

The safest bet is a chronological or combination layout with clear section headings like “Work Experience”, “Education”, and “Skills”. Keep your font standard — think Arial, Times New Roman, or Calibri — and use simple bullet points. That way, the system reads everything in the order it’s supposed to.

Step 2: Use ATS-Compatible File Types

PDF or Word? Which one works better here? It depends on the system the employer uses, but Word files (.doc or .docx) are generally the surest way since most ATS programs handle them well.

Some newer ATS can handle PDFs, but older or less sophisticated ones might stumble. So when in doubt, stick to .docx unless the job listing specifies otherwise. Plus, Word docs let you make quick edits without messing up your formatting — a nice bonus.

Step 3: Optimize Your Keywords

Look, these systems don’t guess what you mean on the page — they look for specific words or phrases. This means you need to match the language of the job description exactly when possible.

But here’s the tricky bit: don’t stuff your resume with keywords. It needs to read natural. Instead, sprinkle them in relevant spots, especially in your skills and job descriptions. Use full phrases and common abbreviations (e.g., “Project Management” and “PM”) to cover every base.

Step 4: Avoid Complex Elements

Tables, text boxes, graphics, and headers or footers often break ATS parsing. They can jumble up the order of your details or cause information to vanish from the system’s view.

Try to use straightforward formatting only. You can design your resume visually elsewhere, but the file you submit should be stripped down: no tables, no columns, just simple lines of text segmented by clear headers.

Step 5: Test Your Resume with an Online ATS Scanner

Before sending your resume off, use an ATS resume checker tool — these online services simulate how different systems read your document. They show which keywords you’re missing or how your formatting might cause trouble.

You can try the free and popular ATS Resume Checker by CV Owl. It’ll scan your resume, highlight weak spots, and give tips for fixing them. Testing here means you catch issues long before your resume meets an actual recruiter’s desk.

Step 6: Simplify Your Contact Information

ATS systems look for your name, phone number, email, and sometimes location right away. Embedding these in headers, footers, or images can cause them to get missed completely.

Keep your contact details at the top in plain text form. Don’t use icons or special characters for your phone or email — they might not parse correctly. And just use your city and state, not the full address.

Step 7: Use Standard Section Headings

Sure, you want to stand out, but labels like “What I’ve Done” or “My Story” might confuse the ATS. These systems recognize only typical headings like “Work Experience”, “Education”, “Skills”, or “Certifications.”

Stick with these conventional titles to make sure your info ends up in the right category during parsing. This also helps recruiters scan your resume faster once you’re past the software stage.

Step 8: Check Your Resume’s Text Readability

Some ATS systems struggle with long paragraphs or heavy jargon. Short and punchy sentences work better here. Also avoid using unusual acronyms unless you spell them out somewhere.

Run your resume through a tool that samples the plain text extracted from your file, verifying that the content is logically ordered and all critical details show up. If not, reformat and test again.

Step 9: Mind the Whitespace and Margins

Yes, white space is your friend when humans are reading, but too much can confuse the ATS. Margins should be standard (at least half an inch) and your document free from large gaps or oddly spaced lines.

Overuse of spaces or empty lines can cause ATS to interpret your resume as fragmented data, possibly losing vital information.

Step 10: Run Final Manual Checks

Don’t rely solely on technology. Open your resume in a plain text editor like Notepad or TextEdit. How does it look? Is everything clear and in order? This reveals how an ATS might read your file.

Also, ask someone else — a recruiter or an experienced friend — to review the resume. They may spot formatting oddities or keyword gaps you missed.

Taking It Beyond: Why You Should Keep Testing and Updating

ATS software changes, and so do job descriptions. What works today might not work six months from now. That’s why keeping your resume fresh and re-running tests before every application gives you an edge.

And before you apply, checking yourself against tools like CV Owl’s ATS Resume Checker isn’t just a good idea — it’s almost mandatory if you want to stay in the running.

Conclusion: Don’t Just Submit, Outsmart the ATS

At the end of the day, your resume is your first impression — but most of that impression is formed by software now. It’s not enough to have great experience and skills; if your resume isn’t readable by ATS, you’re out of the game before it starts. Take these steps seriously: choose a simple format, use the right keywords, avoid tricky layouts, and test your resume using dedicated tools. Keep improving it. Because when you outsmart the ATS, you get your shot at a human reader and the job itself. So start testing today — your next opportunity might just depend on it.
