Why Your ATS Score Is Lower Than You Think
Most candidates assume their ATS score is low because they lack experience. That is rarely the real reason. ATS systems rank resumes based on three factors: how well your keywords match the job description, whether the parser can read your formatting correctly, and whether your section headers are ones the system recognizes.
A candidate with ten years of perfect experience can score lower than a junior applicant simply because their resume uses a two-column layout the ATS cannot parse, or because they wrote "stakeholder coordination" when the job posting said "stakeholder management." The ATS does not know those mean the same thing - it is doing a text comparison.
The good news: all three causes are fixable in under an hour. The fixes below address each one directly, with before-and-after examples so you can see the exact changes to make.
Fix #1: Close the Keyword Gap
Keyword matching is the biggest driver of your ATS score. The system compares the text in your resume against the job description and calculates overlap. Every required term in the posting that does not appear in your resume is a missed point.
The keyword gap is almost always a terminology problem, not an experience problem. Candidates use near-synonyms that mean the same thing but score zero because ATS systems compare exact strings.
Before / After
Before (scores zero):
"Led coordination across business units and senior leadership"
After (matches job posting):
"Led stakeholder management across business units and senior leadership"
The process to close the gap:
- 1.Copy the full job description into a document.
- 2.Highlight every hard skill, tool, methodology, and certification mentioned.
- 3.Search your resume for each term. Every miss is a gap.
- 4.For every gap where you have the real experience, rewrite your bullet to use the posting's exact language.
Pay extra attention to terms that appear more than once in the posting - those are the highest-weighted keywords in the ATS scoring model.
Fix #2: Strip Out ATS-Breaking Formatting
Formatting is the silent score killer. Layouts that look sharp in a PDF viewer are often the same ones that cause ATS parsers to scramble your content or skip it entirely. When the parser cannot read your resume, it cannot match your keywords - even the correct ones.
The most common formatting failures:
Formatting Checklist
- -Two-column layout - ATS parsers read left to right across columns, merging job title and company name into one scrambled string. Switch to a single column.
- -Tables for skills - A 3-column skills table often parses as one unreadable merged line. Use a plain comma-separated list instead.
- -Text boxes - Content inside text boxes is invisible to most ATS parsers. If your name or contact info lives in a text box, the ATS may not know who you are.
- -Headers and footers - Many parsers skip document headers and footers entirely. Keep all content in the main body.
- -Fancy fonts and icons - Decorative fonts and icon bullets can encode as unreadable characters. Use Arial, Calibri, or Georgia with plain dash bullets.
The quick test: copy your entire resume and paste it into Notepad or a plain text editor. If the result looks clean and logically ordered - name at top, experience in sequence, skills readable - the ATS will parse it correctly. If it looks scrambled, you have a formatting problem that is costing you score points.
Fix #3: Use Standard Section Headers
ATS systems are trained on a specific vocabulary of section labels. When your headers match what the system expects, it correctly categorizes your experience, education, and skills - and scores them accordingly. When they do not match, entire sections can be miscategorized or dropped from the parse.
Before / After
Avoid (risky headers):
- "Where I've Made an Impact"
- "My Toolkit"
- "Academic Background"
- "What I've Earned"
Use instead:
- "Work Experience"
- "Skills"
- "Education"
- "Certifications"
The full list of safe headers every ATS reliably recognizes:
- -Work Experience (also "Professional Experience" or "Experience")
- -Education
- -Skills (also "Technical Skills")
- -Summary (also "Professional Summary")
- -Certifications
Creative headers feel personal, but they cost you score points in every ATS that does not recognize them. The standard labels are the safest choice every time.

These three fixes address the most common score killers, but there are subtler issues that are difficult to catch manually - unusual font encoding, embedded images used as bullet points, incorrect date formats that confuse experience-length calculations.
After you make the changes above, run your resume through an ATS checker to confirm your score actually moved. Guessing is not enough - you need the number. A dedicated tool gives you the full picture: which keywords you are still missing, which formatting issues remain, and what your revised score is against a specific job description.
