The Modern Resume ATS and Keywords (Applicant Tracking Systems)

How to Test if Your Resume is ATS-Friendly

Learn how to test your resume for ATS compatibility using the plain text method, proper formatting, and keyword alignment so recruiters can find you in their applicant tracking system.

Focus and Planning

What You Should Remember

1 Keep your resume simple and in one column.

To pass the basic computer check, use normal fonts. Do not put important information inside pictures, graphs, or special text boxes. Saving your resume as a regular PDF or Word file helps the software easily "read" everything without getting confused.

2 Think of the computer like a search tool, not a judge.

Understanding the human side means knowing the computer doesn't "reject" you; it just sorts your information. Your main goal is to use the right labels so a recruiter can find your file quickly when they search for specific skills.

3 Use the "Copy-Paste" check right away.

To see if the computer can read your resume, select all the text and paste it into a simple text program like Notepad. If the text looks mixed up, out of order, or disappears, the computer system will have trouble processing your application correctly.

4 Use the exact words from the job description.

Find the main skills and job titles used in the job listing and use those exact words on your resume. The computer looks for direct matches. If the job asks for "Customer Service" and you write "Client Relations," the system might miss you entirely.

The Secret of the Application System Revealed

The real reason you don't hear back isn't a "robot" throwing your resume away. It's a mistake in how the computer reads your file. An Applicant Tracking System (ATS) doesn't read your resume like a person; it tries to break down your document and place the parts into a digital profile.

When you focus too much on how your resume looks instead of how the information is organized, your job history often gets mixed up or left out. If a recruiter filters for five years of experience and the system can't sort your dates correctly, a human hiring manager won't see you, no matter how many important words are on your paper.

Common advice tells you that you must hit a certain "keyword percentage" or remove all design elements to be seen. As we cover in our guide on the myth of the perfect ATS-optimized resume, these ideas are misleading.

Focusing on Correct Data

  • Controlling your job search means testing your resume for correct data using methods like the "Plain Text Check."
  • Instead of trying to get high scores, you need to focus on how recruiters search, making sure your resume correctly feeds the specific database filters for job titles and degrees that humans check before they even open your resume.
  • This guide gives you the technical and mental steps to succeed.

What is an ATS-Friendly Resume?

An ATS-friendly resume is a document formatted so applicant tracking software can read, parse, and organize every piece of your information into the correct database fields. If the software can't extract your job titles, dates, and skills into the right slots, recruiters won't find you when they search their candidate database.

An Applicant Tracking System (ATS) is software that collects job applications and sorts them into searchable candidate profiles. It doesn't score or judge your resume the way most people think. Instead, it breaks your document apart and places each detail (your name, phone number, job titles, dates, skills) into labeled fields. Recruiters then search and filter those fields to find people who match their open roles.

According to Jobscan's 2025 State of the Job Search report, 97.8% of Fortune 500 companies use an ATS, and 99.7% of the 384 recruiters surveyed use keyword filters to sort and find candidates. That means your resume isn't competing against a "robot judge." It's being filed in a digital cabinet, and the filing needs to be accurate for anyone to pull your folder. (For more on where this technology is heading, see our piece on how AI is changing applicant tracking systems.)

"There is no more sure-fire way to get your resume lost in an ATS than to clutter your resume with graphics, tables, and creative fonts."

The Data-Sync System: The Mindset for Success

The Data-Sync System

Most job seekers think they are writing for a "robot" that grades them on keywords. But the ATS is just a digital filing cabinet. Its job is not to "read" your resume, but to "organize" your information into a standard database. When your resume design is bad, the data gets mixed up during this organizing step. A recruiter won't see a "rejected" note; they just won't see you. To win, you need to focus on getting the data right, not just stuffing keywords. We focus on passing three mental checks a recruiter does when looking at the database.

1
Checking if Filters Find You

What They're Subconsciously Asking

Before a human sees your resume, they search the database using filters like "Years of Experience" or "Job Title." Jobscan's 2025 recruiter survey found that 76.4% of recruiters start by filtering candidates on skills, and 55.3% filter by job title. This is the first check: "Can I find this person easily?" If your resume uses complex columns or headers that the system can't understand, your "Years of Experience" might show up as "0" or be empty in the search results. Even if you are perfect, you fail this check because the recruiter trusts the filter results. If you don't show up in the search, you don't exist in their talent pool.

2
Checking for Quick Trust

What They're Subconsciously Asking

When a recruiter clicks on your profile, they look at the summary the computer has created. Subconsciously, they ask: "Can I quickly check the timeline of this person's career?" If your simple text data is messy (your dates of work are mixed up with your job titles or your bullet points are jumbled), it takes too much mental effort to see where and how long you worked. Eye-tracking research shows recruiters spend just 6 to 8 seconds on an initial resume scan. With that little time, they will naturally move to a candidate whose data is "clean" and easy to check, thinking that candidate is more organized.

3
Checking for Clear Information

What They're Subconsciously Asking

Recruiters don't read resumes deeply; they scan for "signals": specific milestones, degrees, or main skills that prove you can do the job. The mental check is: "Does the data show they meet the 'Must-Haves' without me having to search hard?" If you focus on hitting a "90% keyword match" using a scanner, you often end up with a resume full of "noise," useless buzzwords that don't tell a story. The Data-Sync System focuses on making the facts correct rather than just counting keywords. By making sure your key facts (Degree, Job Title, Main Skills) are formatted so the system can pull them out easily, you make sure that the recruiter’s first look confirms you meet the main needs. If the important information is buried in noise or broken data, they move on.

The Main Point

The Data-Sync System means winning is about making sure the machine reads your data right, not just hitting high keyword counts. By formatting your resume so the ATS correctly organizes key facts, you pass the recruiter's first checks for visibility, trust, and relevance, making sure they look past the database view and actually check your skills.

Resume System Guide for Different People

If you are: New to the Workforce
The Problem

You need to show you have the "must-have" skills even if you don't have a long work history.

The Fix Strategy
Physical Check

Not applicable

Computer Check

The Keyword Match Check: Copy the job description into a free word cloud tool. See which words are biggest. If those words aren't in your "Skills" or "Education" sections exactly as written, the computer might reject you.

Digital Check

Not applicable

The Result

The system finds the important keywords it's looking for.

If you are: Changing Careers
The Problem

You need to "translate" your old experience so the computer knows it fits the new job type.

The Fix Strategy
Physical Check

Not applicable

Computer Check

The Headline Scan: Put a "Summary" section at the top. Use the exact job title you are applying for as your main title there. This immediately tells the system which group to put you in, even if your old titles were different.

Digital Check

Not applicable

The Result

The system correctly sorts your application into the target role right away.

If you are: Moving Up in Your Career
The Problem

You need to make sure your detailed achievements and data can actually be read by the computer.

The Fix Strategy
Physical Check

Not applicable

Computer Check

The Plain Text Conversion: Save a copy of your resume as a .txt file. Open it and look for "messy" text or missing dates. If the text looks wrong, the computer can't read your achievements; you need to simplify how you organized it.

Digital Check

Not applicable

The Result

Your important numbers and achievements are read and scored correctly by the system.

If you are: An Executive
The Problem

You need to remove "fancy design" elements that often hide your main achievements and leadership history.

The Fix Strategy
Physical Check

Not applicable

Computer Check

Not applicable

Digital Check

The "No-Columns" Check: Many senior resumes use 2-column styles or charts to look good. Most ATS read from the first column across the entire page. Switch to a single column so your leadership numbers stay connected to the right company name.

The Result

Your most important leadership details (like budget size or team scale) stay linked to the right context.

Computer System Check: From "Hidden" to "Ready for Interview"

Good Advice vs. Bad Advice Analysis

Bad advice tells you to "trick" or "fool" the system. Good advice focuses on making sure your data is organized correctly so recruiters can find it easily when they use precise search filters.

The Sign of Trouble

The "Quiet Failure": You apply for many jobs you qualify for but never get any replies or interview invitations.

The "Bad Advice" Fix

Use a free "ATS Scanner" to try and get a 95% keyword score and stuff the page with different words that mean the same thing as the job title.

The Expert Fix

The Plain Text Check: Save your resume as a .txt file. If the dates separate from job titles or the text becomes jumbled, the system can't "file" you correctly. If the system can't file you, you won't show up when recruiters search.

The Sign of Trouble

The "Empty Box" Problem: When you upload your resume, the online form stays empty or fills the "Work History" section with nonsense.

The "Bad Advice" Fix

Remove every line, column, and design element to make the file "boring" so a "robot" doesn't get confused and reject you.

The Expert Fix

Fix Data Structure: Make sure your resume follows a simple order (Company > Title > Dates). The system isn't "rejecting" you; it's failing to put your information in the correct digital fields. Fix the layout so your data goes into the right boxes.

The Sign of Trouble

The "Black Hole": You have the exact skills needed, but recruiters seem to hire people with less experience than you.

The "Bad Advice" Fix

Put the entire job description in 1-point white font at the bottom of your resume to "trick the computer" into thinking you match.

The Expert Fix

Solve for Search Behavior: Recruiters don't read every resume; they use filters like "Location," "Degree," and "Years of Experience." If your resume structure doesn't support these specific database searches, you stay hidden, regardless of your keywords.

Quick Answers: How to Make Your Resume Safe for the System

Do two-column resumes work with ATS?

The Truth: It won't get "thrown out," but it will get scrambled. Most ATS software reads from left to right across the whole page. If you have your contact info in a left column and your experience in a right column, the software might mix them together into one confusing sentence. When a recruiter searches for "Project Manager," and your resume looks like a jumbled mess in their database, they move on in two seconds.

Quick Tip:

If you want to test this, save your resume as a .txt (Plain Text) file. Open it. Whatever mess you see on that screen is what the system sees. If your phone number is suddenly in the middle of your job duties, change your layout to a single column.

Does hiding keywords in white text work?

The Truth: This is the fastest way to be flagged. Recruiters use a "View Plain Text" mode that removes all formatting and colors. Your "hidden" keywords will appear as one big, strange block of text at the end of your resume. To a recruiter, this looks like you are trying to cheat because your real experience wasn't strong enough. We go deeper on this topic in can you trick an ATS?

Recruiter Insight:

We don’t just look for the keyword; we look for what is written around it. If the system flags you for "Python," but the text says you "watched a video about Python," you’ve wasted my time. I will remember that name, but not in a good way.

Do ATS score checkers actually work?

The Truth: Not really. Websites that give you a "95% Match Score" are often just trying to sell resume writing help. Every company sets up its ATS differently. A "perfect" score on one of these sites doesn't know about the specific "deal-breaker questions" a recruiter has set up (like "Do you have a certain license?" or "Can you travel?").

Quick Tip:

Instead of chasing a score, focus on keeping your section titles standard. Use boring titles like "Work Experience" and "Education." If you get creative and call it "My Professional Journey," the ATS won't know where your jobs start or end, and your data won't be searchable.

Should I submit a PDF or Word resume?

The Truth: This is a common question. While modern systems can read PDFs, older systems (still used by many large companies) can have trouble with the "layers" in a PDF. If you made your resume in a design program like Canva, the PDF is actually just a picture, not text. The ATS will see a totally blank page.

Recruiter Insight:

Unless the job specifically asks for a PDF, use a standard .docx file. It is the most common file type for almost all hiring platforms. It's the "safest" choice to make sure your data lines up correctly in the recruiter’s search fields.

What is a good ATS score for a resume?

The Truth: There is no single "ATS score" that all systems use. Each company configures its own filters and deal-breaker questions. The scores you see on free checker websites are estimates based on keyword overlap with a job description. A score above 80% on these tools usually means your resume has strong keyword alignment, but it tells you nothing about whether the recruiter has set up custom filters for location, certifications, or years of experience.

Quick Tip:

Use checker tools to spot missing keywords, but don't obsess over the number. Focus on matching the exact job title, listing your skills in a dedicated section, and using standard section headings.

How do I do a plain text test on my resume?

Step by step: Open your resume in its original format (PDF or Word). Select all the text (Ctrl+A or Cmd+A), copy it (Ctrl+C or Cmd+C), and paste it into a plain text editor like Notepad on Windows or TextEdit on Mac (set to plain text mode). Look at the result. If your name is in the middle of a bullet point, or your dates appear three lines away from the job they belong to, the ATS will have the same confusion.

Quick Tip:

Pay special attention to whether your job titles stay on the same line as their dates and company names. If they separate, switch to a single-column layout and remove text boxes or tables.
