Top 5 ATS Resume Mistakes (And How to Fix Them)

You have the perfect experience. You nailed the cover letter. But weeks go by, and you hear absolutely nothing. The culprit? An Applicant Tracking System (ATS) couldn't read your resume. Here are the top 5 mistakes candidates make, and exactly how to fix them today.

Mistake 1: Getting Too Creative with Design

We all want our resumes to stand out. Unfortunately, heavily designed templates from Canva or Photoshop—complete with multi-column layouts, graphics, and custom fonts—often break when passed through an ATS parser. The machine reads left-to-right, top-to-bottom. Columns confuse it, turning your carefully crafted experience into an unreadable block of text.

The Fix: Use a single-column layout with standard fonts (Arial, Calibri, Times New Roman). Save the creativity for your portfolio.

Mistake 2: Using the Wrong File Format

While many modern ATS platforms accept PDFs, some older, rigid systems still specifically request Microsoft Word (.docx) files. If you upload a PNG, a scanned image PDF, or a corrupted file, the parser will immediately reject it because it cannot extract the text.

The Fix: Always submit a standard, text-based PDF unless the job description specifically demands a Word document. Never submit an image file.

Mistake 3: Ignoring the "Exact Match" Keyword Rule

If the job description asks for a "Project Manager", but your resume says "Scrum Master", a strict ATS might give you a zero for that requirement. If they ask for "Search Engine Optimization", don't just write "SEO". Bots are literal; they look for exact string matches.

The Fix: Tailor your resume for every application. Mirror the exact phrasing used in the job description to ensure the algorithm recognizes your skills.

Mistake 4: Putting Important Info in the Header/Footer

It looks neat to tuck your phone number and LinkedIn URL into the header margin of your document. The problem? Many ATS parsers completely ignore header and footer data. That means your resume might get flagged as "contact information missing".

The Fix: Place your name and contact information directly at the very top of the main body of the document.

Mistake 5: Using Vague Section Titles

Using clever section titles like "My Journey", "Professional Affiliations", or "What I Do Best" will completely break the parser. The ATS relies on standard section headers to categorize your data properly.

The Fix: Stick to the universally recognized classics: "Work Experience", "Education", and "Skills".
