You've applied to 40 jobs. You've heard back from two. If that ratio sounds familiar, the problem might not be your experience, it might be that an Applicant Tracking System (ATS) never actually showed your resume to a human being.
Here's the uncomfortable truth: most job applications today are read by software before they're read by a person. That software assigns your resume a score based on how well it matches the job description and how cleanly it can parse your formatting. If that score is too low, your resume gets filtered out, quietly, automatically, with no rejection email and no explanation.
The good news is you don't have to guess. You can check your ATS score in about the same time it takes to read this sentence, fix what's broken, and re-check before you hit submit.
What Is an ATS Score, Exactly?
An ATS score is a number (usually a percentage) that reflects how well your resume matches a specific job description, as read by applicant tracking software. It's not one universal grade, it changes for every job you apply to, because it's measuring your resume against that job's specific requirements and keywords.
Two things determine your ATS score:
- Keyword match - does your resume contain the skills, tools, titles, and phrases the job description uses? If the posting says "cross-functional stakeholder management" and your resume says "worked with other departments," a keyword-matching system may not connect the two, even though a human obviously would.
- Parseability - can the software actually read your resume's structure? Tables, text boxes, headers/footers, columns, graphics, and unusual fonts can scramble how an ATS extracts your work history, dates, and skills, sometimes badly enough that entire sections vanish from what the system "sees."
A resume can be a great fit on paper and still score poorly if it's built in a way that confuses the parser. That's the trap: you can lose the interview before a person ever opens your file.
How to Check Your ATS Score for Free
You don't need to buy anything or guess based on formatting rules of thumb. eCareerDesign's free ATS score checker gives you an instant, specific readout:
- Upload your resume (PDF or Word).
- Paste in the job description you're applying to.
- Get your score in seconds, along with a breakdown of exactly which keywords are missing and which formatting elements might be causing parsing problems.
Because the score is calculated against the actual job posting rather than a generic checklist, it tells you something a static "resume grader" can't: whether this specific resume is a strong match for this specific job, right now, before you apply.
If you're applying to multiple roles (most people are), it's worth re-checking for each one, a resume that scores 90% for one posting can easily score 60% for a different role in the same field, simply because the required keywords shifted.
What Actually Lowers an ATS Score (and How to Fix Each One)
1. Missing keywords from the job description
This is the single biggest factor. If a posting repeatedly uses a specific term, a tool, a certification, a methodology, and your resume uses a different word for the same thing, add the posting's exact phrasing (where it's honestly true of your experience). This isn't keyword stuffing; it's speaking the same language as the person and the software reading your resume.

2. Tables, columns, and text boxes
Multi-column layouts and resumes built in design tools (rather than a standard document format) are the most common cause of an ATS misreading, or entirely dropping, sections of a resume. If your resume looks visually impressive but uses a table to lay out your skills or a text box for your summary, there's a real chance an ATS never sees that content at all. Stick to a single-column, standard-section layout.
3. Headers, footers, and graphics
Contact information placed in a document header or footer is invisible to many ATS parsers. Same goes for logos, icons, and skill "meter" graphics, they don't parse as text, so any information embedded only in them (a proficiency level shown as a bar graph, for instance) simply doesn't register.
4. Uncommon file formats or unusual fonts
Stick to PDF or .docx unless the application explicitly asks for something else, and use a standard, widely-supported font. Decorative or unusual fonts can render as garbled characters once the ATS extracts the text.
5. Non-standard section headings
"Where I've Made an Impact" might read well to a person, but an ATS is often trained to look for standard section labels like "Experience," "Education," and "Skills." Creative headings can cause the system to miscategorize, or miss, the content underneath them.
Why This Matters More Than It Used To
ATS adoption isn't new, but the volume of applications each posting receives has grown sharply, which means more companies lean on scoring thresholds to cut volume before a recruiter ever looks at a resume. A resume that would have gotten a callback five years ago on relevance and experience alone can now get filtered out purely on formatting or keyword mismatch, regardless of how qualified the candidate actually is.
That's exactly why checking your score, not just guessing at "ATS-friendly formatting" rules, matters. Two resumes can both look clean and professional to a human eye while scoring completely differently to the software actually doing the first pass.
ATS Score vs. Resume Match Score: What's the Difference?
These terms get used interchangeably, but they're not quite the same thing:
- ATS score generally refers to how well a resume can be parsed and read by applicant tracking software, plus how well its content matches a job's keywords.
- Resume match score (as eCareerDesign calculates it) goes a step further, scoring the overall alignment between your resume and a specific job description, keywords, but also relevant experience and skills, to give you a fuller picture of your fit, not just a parsing check.
In practice, you want both: a resume that a machine can read cleanly, and content that's genuinely well-matched to the role. Check the first with the ATS checker above; go deeper on the second with eCareerDesign's resume-job match tool and Resume Match Score Explained.
A 5-Minute Pre-Submit Checklist
Before you hit "apply," run through this:
- Run your resume and the job description through the free ATS score checker.
- Add any high-relevance missing keywords the results surface, only ones that are true of your actual experience.
- Confirm your resume uses a single-column layout with no tables, text boxes, or header/footer contact info.
- Confirm section headings are standard ("Experience," "Education," "Skills," not creative alternatives).
- Save as PDF or .docx, re-check the score, and only then submit.
Frequently Asked Questions
Is a free ATS checker actually accurate? A good ATS checker won't give you the exact score every company's specific ATS software would generate, those systems vary by vendor and by employer configuration, but it will accurately flag the two things that matter most across virtually all of them: keyword alignment with the job description, and structural/formatting issues that block clean parsing. Fixing both meaningfully improves your odds regardless of which specific ATS a company uses.
Do I need to hit 100%? No, treat the score as a directional signal, not a pass/fail gate. A score in the strong range with the major missing keywords addressed and no formatting red flags is usually enough to clear the automated screen; the goal is getting your resume in front of a human, not gaming a perfect number.
Should I use a different resume for every job? For any role you're seriously pursuing, yes, tailoring the keywords and emphasis to each specific posting is exactly what raises your ATS and match scores. See How to Tailor Your Resume to a Job Description for a fast, repeatable process.
Can a well-formatted resume still fail an ATS check? Yes, if the content itself doesn't match the job's keywords closely enough, clean formatting solves the parsing half of the problem, not the relevance half. That's why the checker scores both.
