Top 10 ATS Parsing Mistakes That Kill Your Resume (And How to Fix Them)

Research shows that 43% of resumes are automatically rejected by ATS due to parsing errors—not because candidates aren't qualified, but because their resumes can't be read properly. Don't let formatting mistakes cost you your dream job.

You might be the perfect candidate, but if the Applicant Tracking System can't parse your resume correctly, you'll never get the chance to prove it. These 10 mistakes are the most common culprits behind ATS rejection. Let's fix them.

1. Using Complex Tables for Layout

The Problem: Many resume templates use tables to create multi-column layouts or align content. While this looks professional to humans, most ATS systems struggle to extract information from table cells correctly.

What Happens:

  • Text gets jumbled or displayed out of order
  • Information ends up in wrong sections
  • Entire sections may be skipped completely
  • Dates and company names get separated from job titles

The Fix:

  • Use single-column layouts with clear section breaks
  • Rely on spacing and indentation instead of table cells
  • Test your resume by copying it into Notepad—if the layout breaks, so will ATS parsing

Quick Test

Open your resume, select all text (Ctrl+A), copy it, and paste into Notepad. If the information is still readable and in logical order, you're good. If it's scrambled, remove the tables.

2. Putting Important Information in Headers or Footers

The Problem: Many ATS systems completely ignore headers and footers, meaning any information placed there is lost.

Commonly Lost Information:

  • Contact details (phone, email, LinkedIn)
  • Your name (if only in header)
  • Page numbers with job titles
  • Important certifications or licenses

The Fix:

  • Move all contact information to the main document body at the top
  • Include your name at the beginning of the main content
  • Keep headers/footers minimal or empty entirely
  • Repeat your name on subsequent pages in the body text if needed

Correct Contact Section Format:

John Smith
Email: john.smith@email.com | Phone: (555) 123-4567
LinkedIn: linkedin.com/in/johnsmith | Location: New York, NY

3. Using Graphics, Images, or Photos

The Problem: ATS cannot read text embedded in images. Any information in graphic form is invisible to the system.

Elements to Remove:

  • Profile photos or headshots
  • Company logos
  • Skill rating graphics or bars
  • Charts or infographics
  • Decorative design elements
  • Text converted to images

The Fix:

  • Replace skill graphics with simple text lists
  • Use text instead of images for all information
  • Remove photos entirely (they're also a source of bias)
  • Convert infographics to bullet-pointed achievements

4. Using Non-Standard Section Headings

The Problem: ATS systems are programmed to look for specific section headers. Creative headings confuse the parser and cause it to misclassify information.

Creative Headers vs. Headers That Parse

Creative header that fails Standard header that works
"My Journey"Work Experience / Professional Experience / Employment History
"What I Know"Skills / Core Competencies / Technical Skills
"Places I've Learned"Education / Academic Background
"Accomplishments"Achievements / Awards / Certifications
"Tech Stack"Technical Skills

The Fix:

Replace creative headers with standard terminology. Save the creativity for your achievements and accomplishments, not your section titles.

5. Incorrect Date Formatting

The Problem: Inconsistent or unusual date formats confuse ATS, causing it to miscalculate your employment duration or fail to parse dates entirely.

Date Formats: Problematic vs. Recommended

Problematic formatWhy it fails Use instead
"Summer 2023"Too vague to place on a timeline"January 2023 - Present"
"2022-2024"Ambiguous start and end months"Jan 2023 - Mar 2025"
"Jan '22"Inconsistent abbreviation"01/2023 - 03/2025"
"Q1 2023"Quarters aren't a standard parser format"2023 - Present" (if month isn't important)
"2023 to 2024"The word "to" can break date extractionAny format above, with a hyphen

The Fix:

  • Be consistent throughout your resume
  • Use "Present" for current positions (not "Current" or "Now")
  • Include month and year for maximum clarity
  • Use hyphens or dashes to separate date ranges (not "to" or "through")

6. Overusing Special Characters and Symbols

The Problem: Many special characters break ATS parsing or display as garbled text, making your resume unreadable.

Risky Characters and Their Safe Alternatives

Avoid Safe alternative
Stars as bullet points (★, ✭, ☆)Simple bullets (•) or hyphens (-)
Decorative symbols (♦, ◆, ▪, ►)Standard keyboard characters only
Math symbols (≥, ≤, ≈, ±)Words: "over", "under", "about"
Arrows (→, ⇒, ↑)Words: "led to", "increased", "grew"
Special punctuation (—, °)Plain hyphens and text
Currency symbols (£, €, ¥) when unnecessary"USD" or "$" (common symbols are usually safe)

The Fix:

Do a find-and-replace for all special characters. If it's not on your keyboard, consider replacing it with a standard alternative.

7. Using Inappropriate File Formats

The Problem: Some file formats are incompatible with ATS or lose formatting during parsing.

File Format Compatibility

FormatATS-safe?Notes
.docx YesMicrosoft Word 2007+ — the most compatible choice
.pdf (text-based) YesWidely accepted, maintains formatting
.pages NoMac Pages format — not readable on most ATS
.jpeg / .png NoImages of resumes can't be parsed at all
Scanned PDF NoParses as an empty document unless OCR-processed
.odt NoOpenOffice format — limited compatibility
.doc (legacy) NoCompatibility issues with modern ATS

The Fix:

  • Check the job posting for file format requirements
  • Default to .docx if no preference is stated
  • If using PDF, ensure it's created digitally (not scanned)
  • Test your PDF by trying to select and copy text—if you can't, ATS can't either

8. Neglecting Keywords and Skills

The Problem: Even a perfectly formatted resume will be rejected if it doesn't contain the keywords the ATS is searching for.

Common Keyword Mistakes:

  • Using generic terms instead of specific skills
  • Missing industry-standard acronyms
  • Not matching job description language
  • Omitting soft skills that are required
  • Failing to include both acronyms and full terms

The Fix:

  1. Analyze the job description: Highlight all required and preferred skills
  2. Create a dedicated skills section: List relevant keywords clearly
  3. Use exact terminology: If they say "JavaScript," don't just say "programming"
  4. Include variations: Use both "SEO" and "Search Engine Optimization"
  5. Integrate naturally: Incorporate keywords throughout your experience descriptions

Example Keywords Section:

Technical Skills: Python, SQL, JavaScript, React, Node.js, AWS, Docker, Git
Data Analysis: Tableau, Power BI, Excel, Statistical Analysis, Data Visualization
Marketing: SEO (Search Engine Optimization), Google Analytics, Content Marketing, A/B Testing
Soft Skills: Project Management, Team Leadership, Client Communication, Problem Solving

9. Using Text Boxes for Content

The Problem: Text boxes are treated as separate floating elements by ATS, causing the content to be parsed out of order or skipped entirely.

Common Text Box Uses (All Problematic):

  • Sidebar sections for skills or contact info
  • Highlighted achievements or quotes
  • Separate boxes for different job positions
  • Callout boxes for key accomplishments

What Happens:

ATS may read your text boxes at the end of the document (after all other content), making your resume appear disorganized. In worst cases, content in text boxes is completely ignored.

The Fix:

  • Remove all text boxes from your resume
  • Convert content to regular paragraph text
  • Use indentation and spacing to create visual hierarchy
  • Rely on section headers and bullet points for organization

10. Submitting Without Testing

The Problem: The biggest mistake is assuming your resume will parse correctly without testing it first.

Why Testing Matters:

  • You can't see how ATS reads your resume without checking
  • What looks good to humans may be unreadable to software
  • Small formatting issues can have big consequences
  • Different ATS systems may parse differently

How to Test Your Resume:

  1. Plain text test: Copy and paste your entire resume into Notepad or TextEdit. If it's still readable and logically ordered, formatting is likely okay.
  2. ATS simulator: Use a free ATS checker tool to see exactly how your resume is parsed and what information is extracted.
  3. Keyword analysis: Compare your resume against job descriptions to identify missing keywords.
  4. File format test: If using PDF, try selecting and copying text. If you can't select it, ATS can't read it.
  5. Multiple device test: Open your resume on different computers and devices to check for compatibility issues.

The Fix:

Never submit a resume without testing it first. Use our free ATS checker to simulate how your resume will be parsed and receive specific recommendations for improvement.

Bonus Mistake: Lying or Keyword Stuffing

While not a parsing mistake, this deserves mention: Some candidates try to "game" ATS by hiding keywords in white text or stuffing irrelevant keywords throughout their resume.

Why This Fails:

  • Modern ATS can detect hidden text and may auto-reject
  • Human reviewers can see through keyword stuffing
  • You may be blacklisted from future applications
  • If hired under false pretenses, you risk immediate termination

The Right Approach:

Only include keywords that genuinely reflect your skills and experience. If you don't have a required skill, consider whether the job is really a good fit—or if you can quickly learn the skill and note it as "in progress."
