ATS Resume Parsing Errors and Fixes: How to Optimize Your Resume for Applicant Tracking Systems

Understanding ATS and Resume Parsing

Before addressing parsing errors, it’s essential to understand what exactly ATS is and how resume parsing works.

What is an Applicant Tracking System?

An Applicant Tracking System is a software tool recruiters use to collect, organize, and rank job applications electronically. ATS helps automate the early stages of recruitment by scanning resumes for keywords, experience, skills, and qualifications relevant to the job description.

How Does Resume Parsing Work?

Resume parsing refers to the process where ATS software extracts data from resumes to transform it into structured information. This includes details like contact info, work experience, education, skills, and certifications. Parsed data allows ATS to match applicants against job requirements.

However, discrepancies in formatting, unusual fonts, or complex layouts can block accurate parsing, causing critical information to be omitted or misplaced.

Common ATS Resume Parsing Errors

Many candidates unknowingly submit resumes that cause parsing issues. Let’s explore the key errors that trip up most ATS software.

1. Complex Formatting and Graphics

Use of tables, text boxes, headers/footers, and graphics such as logos or icons can confuse parsing algorithms. These elements often prevent ATS from correctly reading or extracting text.

2. Improper Use of Fonts and Special Characters

Non-standard fonts, symbols, or special characters like bullets and arrows may not convert properly during parsing. This can garble your information or make sections unreadable.

3. Missing Standard Section Headings

ATS programs frequently scan for common headings like “Work Experience,” “Education,” and “Skills”. Using creative or non-traditional headings like “My Journey” or “What I Bring” can cause ATS to overlook sections entirely.

4. Use of Headers and Footers for Important Info

Putting contact information or critical qualifications in the header or footer of a resume can result in ATS skipping that data since many parsers ignore these areas.

5. Unrecognized File Formats

Some ATS can only reliably parse resumes in certain formats such as .docx or PDF with readable text. Scanned images or password-protected files often fail to parse.

6. Overuse of Acronyms and Abbreviations

Relying solely on acronyms without spelling them out can prevent ATS from recognizing relevant skills or qualifications correctly.

7. Formatting Date and Location Details Incorrectly

Non-standard formats or missing dates in your employment or education history may confuse ATS and omit important timeline information.

8. Keyword Stuffing or Lack of Relevant Keywords

Either overwhelming ATS with irrelevant keywords or using too few relevant ones can impact parsing accuracy and your resume’s ranking.

How ATS Parsing Errors Affect Your Job Application

When parsing errors occur, the ATS may misinterpret or miss sections of your resume entirely. This often leads to:

• Lower ATS Scores: Your resume ranks poorly against others, reducing your chances of being shortlisted.
• Missing Key Information: Hiring managers see incomplete or poorly formatted resumes.
• Increased Risk of Rejection: Automatic filters may reject your application unintentionally.

Knowing how to fix these errors significantly improves your chances of passing ATS filters and getting recruiter attention.

Best Practices & Fixes to Resolve ATS Resume Parsing Errors

Implementing these actionable fixes will enhance your resume's ATS compatibility and parsing success.

1. Use Simple, Clean Formatting

• Favor a single-column layout to avoid confusion.
• Use standard fonts like Arial, Calibri, or Times New Roman.
• Avoid tables, text boxes, or graphics that may distort parsing.

2. Stick to Common Section Headings

• Use universally recognized headers such as Work Experience, Education, Skills, and Certifications.
• Keep headings bold and easily identifiable.

3. Place Key Information in the Main Body

• Put your contact details in the main text area, not in headers or footers.
• Avoid using columns for important personal or professional info.

4. Use Standard File Formats

• Submit resumes in common formats preferred by ATS: .docx or text-based PDFs.
• Test your PDF to ensure the text is selectable, not scanned images.

5. Spell Out Acronyms and Abbreviations

• Include both full terms and acronyms (e.g., “Master of Business Administration (MBA)”).

6. Format Dates Consistently

• Use clear, standardized date formats like “Jan 2026 – Dec 2026”.
• Ensure date fields are complete for all job entries and education.

7. Include Relevant Keywords Naturally

• Analyze the job description for important keywords and integrate them throughout your resume.
• Avoid keyword stuffing to keep readability intact.

8. Avoid Headers, Footers, and Complex Layouts

• If you must use headers/footers, keep them free of important text that ATS needs to parse.
• Keep layout simple—no multi-column or two-page spreads unless absolutely necessary.

Testing Your Resume for ATS Compatibility

After implementing fixes, verify how well your resume parses using the following methods:

1. Use Online ATS Resume Scanners

Several tools offer free or paid ATS resume checks to simulate how your resume is read by software. Try platforms like Jobscan, Resunate, or CV Owl’s ATS resume analyzer tool.

2. Copy-Paste into Plain Text Editor

Paste your resume into a plain text editor (like Notepad) and review the output. This reveals how an ATS might read your document—check for missing data or jumbled sections.

3. Consult Recruiters or Career Coaches

Recruitment professionals with ATS experience can provide valuable feedback to enhance your resume’s parsing performance.

Additional Tips for ATS-Friendly Resumes

Keep It Concise but Comprehensive

Ensure your resume highlights relevant experience and skills without unnecessary fluff.

Use Standard Job Titles Where Possible

Generic job titles are easier for ATS to interpret than creative ones.

Customize Your Resume for Each Job Application

Tailoring keywords and skills per job description improves match rates in ATS scoring.

Include Both Soft and Hard Skills

Balance technical keywords with workplace competencies recruiters value.
