Check your resume’s ATS score before you apply
Upload your resume, paste a job description, and get an ATS compatibility score with specific fixes, so formatting and wording don't quietly knock you out before a recruiter reads it.
What an applicant tracking system actually checks
When you apply online, your resume usually passes through software before a person sees it. Here's what that software looks at.
An applicant tracking system is software employers use to collect, parse, and rank applications. Most large companies and plenty of smaller ones run tools like Workday, Greenhouse, Lever, iCIMS, or Taleo. When you click “Apply,” your resume enters that system before anyone reads it.
First it parses the file, pulling out the text and mapping it into fields like name, contact details, work history, education, and skills. Complex formatting (tables, multi-column layouts, images, or unusual fonts) can scramble that text or drop whole sections, which is where a lot of resumes trip up.
Then it compares your content against the job description, matching skills, certifications, titles, tools, and industry terms, and scores how relevant you look for the role. Knowing what it checks is the first step to writing a resume that makes it through.
resumelon checks your resume against each of these factors and gives you a clear score with specific fixes.
Check your resume in four steps
From upload to a clear, actionable score in a few minutes.
Upload Your Resume
Upload your resume as a PDF or DOCX. The parser reads the full document and pulls out the text, section headings, and structure for analysis. It takes seconds and works with any format.
Paste the Job Description
Paste the job description you're targeting. We pull out the required skills, qualifications, responsibilities, and terminology the employer's ATS is likely scanning for.
Get Your Score
Get an ATS compatibility score out of 100 in seconds, broken down by formatting, keywords, section structure, and readability so you can see exactly where your resume stands.
Apply Fixes & Recheck
Work through the specific recommendations, then run the checker again to confirm the changes landed.
What we check
The dimensions automated screening actually cares about, so nothing slips through.
Formatting Compliance
An ATS expects a clean, linear document. We scan for tables, text boxes, multi-column layouts, headers, and footers that commonly break parsing, and flag each one with a fix, so your text comes out in the right reading order.
Keyword Density
We compare your resume against the job description for matching skills, certifications, titles, and industry terms, then point out the ones you're missing and where they fit naturally. Without the right terms, strong experience can still score low.
Section Structure
An ATS uses standard headings to sort your information. We check that yours uses recognized labels like Work Experience, Education, Skills, and Summary. Creative headings like My Journey or Toolkit can get sections misfiled or skipped.
Font & Layout
Some fonts and layouts break parsing or read poorly. We check for ATS-safe fonts, sensible sizing, a single-column flow, and consistent margins and spacing.
File Format
We confirm your file is a text-based PDF or DOCX with a selectable text layer. Image-based PDFs, design files, and formats like Pages or ODT are often unreadable to an ATS.
Readability Score
Once past the software, your resume still has to be easy to skim. We look at sentence length, bullet structure, action verbs, and overall clarity, since recruiters read quickly on a first pass.
More than a basic score
The detail and guidance behind the number, so you know what to change and why.
Keyword gap analysis
Rather than just noting that keywords are missing, it compares your resume against the job description and lists the required skills, certifications, and qualifications you haven't addressed, sorted by whether they're must-haves or nice-to-haves. You see which terms to add and where they fit naturally, so nothing reads keyword-stuffed.

Formatting and structure audit
The audit checks the structural parts of your resume (tables, text boxes, images, headers and footers, and non-standard fonts) that cause parsing errors on platforms like Workday, Greenhouse, Lever, iCIMS, and Taleo. Each issue comes with a short explanation and a specific fix, so your resume parses cleanly without looking plain.
