What is ATS Readability and Why Should You Care?
Quick Take:
ATS readability is how easily an Applicant Tracking System can scan, understand, and rank your resume before a recruiter sees it.
Before I learned about this, I thought ATS was another HR buzzword. But it’s not. It’s the filter that decides if your resume gets seen or ignored. ATS stands for Applicant Tracking System, and most companies use it to sift through many job applications.
These systems don’t read your resume like a person does. They scan it like a robot, meticulously scrutinizing the formatting, keywords, headings, and layout. It may be rejected if your file contains fancy fonts, odd column layouts, or missing terms. That happened to me. I used a sleek template I found online. It looked sharp, but the ATS couldn’t read half of it: no proper keywords, a confusing layout, and a total fail.
That’s why ATS readability is so important. You can have excellent skills, but be out of the game if the system can’t read them. Learning how these tools work and reviewing your resume can make all the difference.
Signs Your Resume Might Not Be ATS-Friendly
Quick Take:
Your resume may not be ATS-friendly if it uses complex formatting (such as tables, images, or fancy fonts), lacks the necessary keywords, or has a confusing layout that the software can’t scan properly.
When I first started applying, I spent hours perfecting my resume. I used a stylish template, added icons, and split the layout into two neat columns. It looked amazing to me. But to the ATS? It was chaos.
Applicant Tracking Systems don’t care how pretty your resume is. They care if it’s easy to scan; many standard resume “design tricks” break that. I learned this the problematic way, and here’s what I found:
Common Signs Your Resume Might Not Be ATS-Friendly:
- It uses fancy templates with tables, columns, or graphics
- You’ve skipped essential keywords from the job description.
- You’ve added images, logos, or custom fonts that confuse scanners.
- The layout looks like a checklist, but doesn’t follow standard resume sections.
Pro Tip :
An ATS may fail to read your content correctly if your resume includes images, tables, or two-column designs.
Think of the ATS like an old-school calculator. It can do amazing things—but only if the input is clean and predictable. If you throw in a bunch of noise (like icons or creative layouts), it either skips those parts or gets stuck.
I also made the mistake of using a resume that was “visually creative” but had section headers like “What I Bring” instead of “Work Experience.” Guess what? The ATS had no idea what that meant. It just skipped over it entirely.
So, if you’re wondering why your resume isn’t getting responses, these could be the silent deal-breakers.
How I Tested My Resume for ATS Readability
Quick Take:
I tested my resume for ATS readability using free online tools such as opResume, Jobscan, and ResumeWorded. These tools scanned my resume and flagged formatting issues, keyword gaps, and section mismatches that could confuse ATS software.
Let me be real; I was frustrated. I had spent hours fine-tuning my resume. I even used one of those “modern” templates with slick fonts and sidebars. It looked professional to me. However, after sending it out repeatedly with no replies, I knew something was amiss.
That’s when I asked myself: Is my resume even readable by those ATS things recruiters keep talking about?

What Pushed Me to Try a Resume Checker
It was after a friend casually said, “Maybe your resume isn’t getting seen at all.” That hit hard. I always thought my experience would speak for itself. But if no one was reading it, how could it?
So I Googled “free ATS resume checker” and tried the first tool that popped up—TopResume. I uploaded my shiny resume and waited. Within seconds, I got a full report. And it wasn’t pretty.
Here’s What I Learned From the First Scan:
My file format was acceptable (thankfully).
But my two-column layout confused the parser.
I had used a creative job title (“Content Ninja”—yep) that didn’t match what hiring managers search for.
Keywords? Missing. My resume lacked the core phrases from the job description.
I felt like I’d built a house with no doors. It looked great from the outside—but no one could get in.
So, I kept testing.
I tried Jobscan next, which let me paste a job description and compare it to my resume. That was a game-changer. I saw exactly which keywords I was missing and where my resume fell short.
Finally, I tested it on ResumeWorded, which gave me a more visual breakdown. It even graded different sections, such as “Impact,” “Length,” and “Style.”
My Quick Checklist for Testing ATS Compatibility (What I Did):
- Uploaded resume to 3 different free checkers
- Posted the job description into the keyword scanner
- Reviewed formatting, headings, and layout issues
- Fixed section titles to match standard ATS headings
- Swapped fancy fonts for system-friendly ones like Arial
Pro Tip:
If your resume doesn’t use standard headings like Work Experience, Education, or Skills, an ATS may skip entire sections, costing you the interview.
After fixing those errors and retesting, my “ATS readability score” jumped. And more importantly? I started getting replies.
It wasn’t magic: just proper formatting, targeted keywords, and a resume a machine could finally understand.

Tips to Make Your Resume More Readable for ATS
Quick Take:
To make your resume ATS-friendly, use simple formatting, clear headings, and job-related keywords; avoid using images, icons, and columns.
When I first heard about Applicant Tracking Systems (ATS), I imagined this invisible gatekeeper scanning my resume like a barcode at the grocery store. And honestly, it is! If the system can’t “read” your resume correctly, it may never reach human eyes—no matter how great your experience is. That’s why making your resume readable isn’t just a nice touch—it’s necessary.
Here’s what I learned (the hard way) about keeping things clean, simple, and scanner-friendly.
1. Avoid Images, Icons, and Fancy Columns
Quick Take:
Images, icons, and multiple columns confuse ATS bots; stick to plain text in one-column layouts.
I once used this beautiful Canva template with icons for every section; it looked amazing. But the ATS? It saw blank space and chaos. Most systems can’t process images or columns properly. Your work history or skills might get jumbled—or completely ignored.
So, ditch the design-heavy layouts. One clean column does the trick. Your creativity can shine during the interview, not in your resume format.
2. Use Clear Headings and Standard Fonts
Quick Take:
Use standard headings like “Experience” and “Education” in standard fonts like Arial or Calibri.
Headings like “Work History” or “Professional Experience” are familiar to ATS. Avoid vague or creative ones like “My Journey” or “Where I’ve Been. “Robots aren’t that poetic.
Stick to basic fonts like Arial, Calibri, or Times New Roman. I know it sounds boring. However, clean and boring can be readable and practical. Trust me, it’s not about flair. It’s about function.
3. Save as PDF or DOCX (Not PNG or JPG)
Quick Take:
Always save your resume as a PDF or DOCX file; other formats may break when scanned by an ATS.
I once made the error of uploading a resume saved as an image file. Guess what the ATS read? Nothing. Nothing. It was like handing someone a blank sheet of paper.
Most modern ATS systems prefer PDF or .docx. These formats preserve your layout and keep your text readable. Before submitting, double-check the file type, as it often specifies the desired format.
4. Use Keywords from the Job Description
Quick Take:
Include relevant keywords from the job description so ATS tools recognize your fit for the role.
Think of ATS as a matchmaking engine. It’s looking for a keyword love match. If the job description says “email marketing,” and your resume says “email blasts,” it might miss the connection.
What do I do? I copy the job post into a document, highlight repeated words or key skills, and ensure that those exact terms appear in my resume. Don’t just stuff them in. Make them flow like you’re telling your story.
5. Keep the Layout Simple and Clean
Quick Take:
Use a straightforward structure with bullet points, basic margins, and left-aligned text for maximum readability.
There is no need for boxes, graphs, or color-coded timelines. Clean margins, consistent spacing, and simple bullet points make scanning easier for ATS (and humans).
A tip I live by: If it looks easy to skim on your phone, it’s ATS-friendly too. Think of your resume like a fast-food menu: simple, direct, and without extra sauce.
Final Takeaway:
Making your resume ATS-readable doesn’t mean stripping it of personality—it means presenting your value in a way that both machines and humans can understand.
Quick Checklist Recap:
- Avoid images, icons, and multi-columns
- Use clear section headings
- Stick to basic fonts (Arial, Calibri)
- Save as PDF or DOCX
- Add keywords from the job post
- Please keep it clean and structured
Bonus: How to Read the ATS Report & What to Fix
Quick Take:
To read your ATS report, focus on key scores like formatting, keyword match, and section completeness. Fix flagged areas by adjusting the layout, adding relevant keywords, and using standard headings.
When I ran my resume through an ATS checker for the first time, I expected a pat on the back. Instead, it felt like my resume got roasted by a robot. The report was filled with flags of red, yellow, and even some grays I didn’t know existed. However, don’t worry; it’s not as harsh as it appears.
Think of the ATS report as a health check-up. It’s not judging you. It’s helping you get stronger. Here’s how I broke it down, fixed what was wrong, and finally got a “green light” score.
1. Start With the Score Breakdown
Pro Tip:
First, examine the overall scores, particularly in formatting, keyword relevance, and section completeness.
Most ATS tools give you a score out of 100 or use colored bars to show how well you did. The main sections I watch closely are:
- Formatting: Is your layout simple enough?
- Keywords: Did you use job-specific terms?
- Sections: Did you include Experience, Education, Skills, etc.?
If your formatting score is low, your fonts, columns, or file type are likely confusing the system. A poor keyword score usually means missing key terms from the job post. Trust me, I once skipped the “skills” section entirely, thinking my experience spoke for itself, a big mistake.
2. Keyword Flags Are a Clue, Not a Criticism
Pro Tip:
If keywords are flagged, you’re missing terms the employer wants. Add them where relevant.
I used to worry that using the same word too often would make me sound repetitive. But ATS bots love repetition as long as it’s natural. If the job post says “project management,” don’t write “oversaw operations.” Just say “project management.” The exact match matters.
If the report flags missing keywords, don’t simply add them to a list. Instead, weave them into your bullets or achievements:
- Led project management for cross-functional teams.
- Used Agile methodology in project management tasks.
Simple tweaks like that improved my keyword score by 20 points!
3. Fix Format Flaws Fast
Quick Take:
Low formatting scores indicate that your layout may confuse the ATS—consider using a one-column layout, avoiding images, and clearly defining section titles.
Once, I had a two-column design with icons beside each job title. It looked great on-screen but was completely unreadable in the report. The fix? I switched to a one-column layout, removed icons, and used plain text.
Make sure your headings are standard:
- Professional Experience
- Education
- Skills
- Avoid vague ones like “What I Bring” or “My Journey.” They sound creative, but don’t help the system match your information.
4. Check Missing or Weak Sections
Quick Take:
Missing sections, such as Skills or Education, can cause your ATS score to drop; add them even if they seem obvious.
If the tool says “Skills section missing” or “Experience incomplete,” don’t ignore it. Even if you mention your education in your outline, it won’t be counted unless it’s listed under a proper ‘Education‘ heading.
Once, I left out my Technical Skills section, thinking my job descriptions covered it. The result? The tool didn’t pick up any of my software proficiencies. Adding a bullet list like:
- Adobe Photoshop
- Google Analytics
- HubSpot
- It helped it instantly recognize my qualifications.
Final Thought: Treat the Report Like a Resume GPS
It doesn’t just tell you what’s wrong. It tells you how to get where you want to go. Don’t take flags personally. Use them like GPS recalculations. Every change moves you closer to that interview.
My Final Thoughts: What Worked Best for Me
Quick Take:
Simple formatting, keyword matching, and a clean layout helped me get the best ATS results. Testing and tweaking my resume made all the difference.
After trying multiple resume versions and going down a rabbit hole of ATS advice, I finally found what worked. And no, it wasn’t a fancy design or a secret “hack.” Just a few key changes made my resume click with the system and with real recruiters.
Let me break down what helped me the most so you don’t have to learn it the hard way like I did.
1. Going Simple Won
A unique layout made me stand out. It turned out that it made me disappear in the ATS. When I switched from the two-column format to a basic, one-column layout with standard headings, such as “Experience” and “Skills,” my readability score improved.
Quick Take:
A simple, single-column resume layout is most effective for ATS systems.
And guess what? Recruiters said it was also easier to skim through, with no fancy fonts. No icons. Just clean and clear.
2. Adding Keywords Naturally
This part felt weird at first. I didn’t want to sound robotic. However, it worked when I pulled keywords directly from job descriptions and incorporated them into my bullet points without forcing it.
Pro Tip:
Use keywords from job descriptions naturally in your resume to improve ATS scores.
I’d copy phrases like “digital campaign management” and “SEO optimization” and use them in real examples. The result? More green checkmarks in the ATS report and more replies from hiring teams.
3. Fixing File Format & Rechecking
It sounds small, but saving my resume as a .docx instead of a PDF solved some weird formatting issues. Some ATS tools read Word files more effectively. I’d always assumed PDF was safer. It’s not always true.
Quick Tips:
Saving your resume in .docx format helps avoid formatting issues with many ATS systems.
I also learned to test my resume again every time I edited it. Even a minor tweak, such as changing bullet symbols. could disrupt parsing. Testing after each update gave me peace of mind.
Final Tip: Don’t Guess—Test
If there’s one thing I’ve learned, it’s this: don’t leave your resume to chance. These tools exist for a reason. I treated each test like a dress rehearsal before the big show.
Quick Take:
Always test your resume with an ATS checker before applying; it reveals what needs fixing and boosts your chances.
Take 10 minutes to run your resume through a checker and thoroughly review the results. You’ll spot quick wins, like tweaking job titles or reorganizing bullet points. Those tiny edits can make a big difference.
Over to You
Now that I’ve shared what worked for me, it’s your turn. Tweak. Test. Tweak again. The perfect resume isn’t made in one shot. It’s built through feedback, just like a good recipe.
And hey, if I can go from getting ghosted to getting replies, so can you.
What does ATS look for in a resume?
Short Answer:
ATS tools look for clear formatting, job-specific keywords, and standard resume sections like Experience, Education, and Skills.
When I first learned what ATS scans, I was surprised. It’s not about judging creativity but checking structure and fit. It aims to verify that you used the correct keywords, that your resume includes all the essential sections, and that the layout is machine-readable.
Think of it like a librarian searching for a book. It will be skipped if the title is missing or the author’s name is handwritten in crayon. It’s the same with resumes. The clearer your formatting and the better your keyword match, the more visible you are to the hiring team.
How can I ensure my resume is ATS-friendly?
Short Answer:
Use a single-column layout, standard section headings, and keywords from the job description to make your resume ATS-friendly.
I always tell my friends: don’t try to impress the ATS; try cooperating with it. Stick to standard fonts (such as Arial or Calibri), keep headings simple (e.g., Professional Experience, Skills), and avoid using elements like images, tables, or unusual symbols.
The biggest tip? Mirror the job description. If it says “project coordination,” you should too; don’t rephrase it as “team organization” just to sound unique. Matching terms naturally boosts your ATS score.
Can I test my resume for ATS readability for free?
Short Answer:
Yes! Several free tools let you test your resume for ATS readability and formatting issues.
This was a game-changer for me. Tools like Jobscan (with a limited free version), opResume, and Rezi enable you to paste your resume and assess its performance. They highlight missing keywords and section issues and even offer formatting tips.
I tested mine after each update, and I learned something new every time. It’s like getting feedback from a robotic recruiter (but with no judgment and way less coffee).
Is PDF or Word more compatible with ATS?
Short Answer:
Word (.docx) is often safer for ATS systems, although simple PDFs can also be used, as they avoid complex formatting.
I used to swear by PDFs until I discovered that some ATS tools struggle with certain types of PDFs. Your file might not parse correctly if it has text boxes, icons, or non-standard fonts.
Now, I have two versions of my resume. One in .docx for ATS, and one PDF if I’m emailing it directly to a human. It’s a small step, but it can significantly affect how your resume is perceived (or overlooked).
Which resume format is best for ATS systems?
Short Answer:
The reverse-chronological format is the most ATS-friendly because it’s organized and straightforward.
I’ve tested a few formats—functional, combination, etc. But the reverse-chronological format always performed best. It first lists your most recent experience and follows a clean, predictable order.
Avoid getting too “creative” with the layout. ATS likes consistency, not curveballs. A clean format makes it easier for the system and recruiters to follow your career journey without guessing.
Do fancy resume templates hurt ATS readability?
Short Answer:
Yes—fancy templates with columns, graphics, and icons often confuse ATS systems and lower your score.
Trust me—I learned this the hard way. I once used a beautiful template with icons for skills and a colored sidebar. It looked great, but half the content got lost in translation when I ran it through a checker.
If you love design, keep one fancy version for networking or interviews—but always have a plain, ATS-optimized version ready for online applications. Think of it like attending a job fair: polished yet practical.
