ATS score explained: how resume scanners read your resume + the fixes that actually raise your score

If you’ve ever uploaded a resume and wondered “What is my ATS score?”—you’re not alone. ATS (Applicant Tracking System) software screens and organizes applicants for many employers, especially mid-size and large companies.

Here’s the important part:

What is an ATS score?

An “ATS score” is usually a compatibility estimate—how closely your resume matches a specific job posting based on:

Some platforms show you a numeric score (e.g., 62/100). Others only rank candidates internally. Either way, the underlying concept is the same: match + readability.

ATS score vs. recruiter decision

An ATS doesn’t “hire” you. It helps recruiters manage volume. Your goal is to:

  1. Make your resume machine-readable
  2. Make it clearly relevant to the job you want
  3. Make it credible and scannable for the human who opens it

How ATS resume scanners actually work (simple version)

Most ATS workflows look like this:

  1. Ingest: You upload a PDF/DOCX.
  2. Parse: The system extracts text and tries to label sections (Experience, Skills, Education).
  3. Normalize: It standardizes job titles, dates, and entities (companies, locations).
  4. Match: It compares your resume to a job description (JD) and ranks candidates.
  5. Filter / search: Recruiters search (e.g., “React AND TypeScript AND GraphQL”) and shortlist.

Your resume can fail in two major ways:


The biggest myths about ATS scores

Myth 1: “ATS scores are universal”

They aren’t. Each employer configures their system differently, and different ATS tools behave differently.

Myth 2: “More keywords always increases the score”

Keyword stuffing can backfire. Better: include keywords in context (projects, impact, tools used).

Myth 3: “PDFs are always bad for ATS”

Most modern systems handle PDFs well if they’re clean and text-based (not a scanned image). The bigger risk is weird formatting, columns, and icons.


What improves an ATS score the fastest (high impact, low effort)

If you only do five things, do these:

  1. Use a single-column layout (no sidebars)
  2. Put a Skills section with the tools from the job description
  3. Mirror the JD’s exact terms (e.g., “TypeScript” not “TS” only)
  4. Add measurable outcomes in Experience/Projects
  5. Remove parsing traps (tables, icons, headers/footers with key info)

Use standard section labels:

Keep it predictable

ATS tools love predictable.

Good headings:

Risky headings:


Tech worker: what ATS matching looks for (and how to show it)

For software, data, IT, security, and product roles, matching often depends on:

Example: rewrite a bullet for ATS + recruiter clarity

Before (vague):

After (specific + keyword-rich):

Notice what it includes:


Career switcher: how to raise your ATS match without “fake experience”

Career switchers often lose ATS match because the resume doesn’t clearly connect:

The 3-section approach that works well for switchers

  1. Summary (2–3 lines): say what role you’re targeting and what you bring
  2. Skills (grouped): mirror the JD categories
  3. Projects (with impact): prove the skills are real

Example summary for a career switcher (tech)

Career switcher targeting Junior Data Analyst roles. 5 years in operations using Excel, SQL, and KPI reporting; recently built Power BI dashboards and automated weekly reporting with Python.

This helps both ATS and humans understand relevance fast.

Where most resumes accidentally lose ATS points

Here are the common “silent” failures:

IssueWhy it hurtsFix
Two-column templateParser mis-orders contentSwitch to single-column
Skills shown as icons (no text)ATS can’t read iconsUse text lists
Headers/footers used for contact infoSome parsers ignore themPut contact in main body
“Creative” section namesATS may not classify sectionsUse standard labels
Too many unrelated keywordsLowers relevance signalTrim to target role keywords

How to “keyword match” without stuffing (the safe method)

Step 1: pick 10–20 must-have keywords from the JD

For a backend role, that might be:

Step 2: place them in 3 places

  1. Skills section (grouped)
  2. Experience bullets (used in context)
  3. Projects (especially if you’re a switcher)

Step 3: use the exact term at least once

If the JD says “TypeScript”, include “TypeScript” somewhere—not only “TS”.


FAQ: ATS score questions people actually ask

Is there a free ATS score checker?

There are tools that estimate match, but the most useful “score” is: how well your resume matches the specific job you’re applying to. A free review is most helpful when it checks both format parsing and job match.

We’ve tested and compared the top free ATS checkers in our best free ATS score checker tools guide. You can also try ApplyBuddy’s free review here: https://applybuddy.ai/free-ai-resume-review

What ATS resume format is safest?

A clean, single-column resume with standard headings and plain text skills is the safest across systems.

Should I tailor my resume for every job?

For tech roles, you usually don’t need a full rewrite each time. A practical approach:
