How to optimize a resume for ATS and how to create an ATS-friendly resume have become two of the most important skills job seekers need today. Over 78% of large companies use applicant tracking systems today to filter resumes even before a human ever sees them.
If you are thinking about how to optimize your resume for ATS, the answer is quite simple: try using the right keywords, then follow ATS-friendly resume formatting, and match your resume closely to the job description. An optimized resume helps applicant tracking systems be able to read, rank, and forward your profile to the recruiters, giving you a real chance to get hired.
If your resume is not optimized, you might be rejected even if you're highly qualified.
So, why do even good candidates you know get filtered out?
Let's understand what an ATS is really looking for.
And how can you beat them?
Let's break it down and help you get more interviews.
What Is an Applicant Tracking System (ATS), and How Does It Read Your Resume?
An ATS, or an Applicant Tracking System, is software that companies use to collect, scan, and filter job applications and resumes. Instead of recruiters reading every resume and profile, the system can do the first round of screening automatically.
1. What an ATS (Applicant Tracking System) Is
An applicant tracking system can store resumes in a database.
It will scan your resume for keywords, skill sets, job titles in your priority, job description keywords, and relevant experiences you have in the applied field.
Then it ranks candidates based on how well they match the job according to the description.
So, in simple words, an ATS model decides who moves forward and who gets rejected.
2. Why Companies Use ATS Software
Most of the companies today use ATS because:
- They receive thousands of applications every day.
- For them, manual screening is too slow and time-consuming.
- For the companies, ATS saves time and money at the same time.
- It helps them manage the bulk of candidates, their applications, and resumes quite efficiently.
- Large companies like Amazon, Google, and Microsoft have a heavy reliance on ATS tools.
How ATS Scans, Parses, and Ranks Resumes
ATS uses a process which is called resume parsing. It breaks your resume into some sections, like:
- Your name
- The given address and contact information
- Your relevant skill set and job description keywords (Python, SEO, GAAP) or soft skills (collaboration, leadership)
- Your work history and experience
- Educational Qualifications and Certifications
Then it checks for the following:
- The Resume keywords
- The job description keywords
- Job titles and skills
The more matches you get, the higher your score will be.
Common Reasons Why ATS Rejects Some Resumes
Your resume might have failed because:
- It misses the major keywords
- Has bad formatting
- Using tables and graphics (Quite confusing for ATS tools to scan these)
- Intact with unreadable file formats
- Giving a wrong or elusive sectional title
What Is the Difference Between ATS Screening and Human Review?
Know what ATS looks for:
- Matching major job description keywords
- Structure of your resume and profile
- Matching terms with demand
Whereas, what do humans look for?
- Your Story, if it's personalised
- The relevant field Achievements
- Your Personality during interviews
So at first, you must pass the machine, and then it comes to your turn to impress the human.
How to optimize a Resume for ATS: A Step-by-Step Guide
Let's get practical. This is the heart of optimizing your resume for ATS.
1. Choose an ATS-Friendly Resume Format
An ATS-friendly resume means:
- Giving a single column and clear headings
- Don't use graphics or icons.
- Use a simple layout and font style.
- Try to avoid fancy designs.
2. Use keywords from the job description.
Read the job post carefully before applying.
Highlight the repeated keywords, like your ‘skills’, ‘tools’, ‘certifications’, and ‘job titles’.
These can be your resume keywords.
For example, if the job description asks for “project management”, do not write something like “project coordination”.
3. How to write an ATS-optimized professional summary
So, your summary must include:
- Your job role
- The major key skill sets you have
- How many years of experience do you have in the relevant field?
For example:
“Digital marketing specialist with 5+ years of experience in SEO, content strategy, and paid advertising.”
These help the ATS and the recruiters to understand you easily and quickly.
4. Optimize Work Experience with Job Description Keywords
In your work experience section, use action verbs, metrics, and job-specific terms. Such as “Managed social media campaign, increasing engagement and responses by 45%.”
5. Add a Clear and Relevant Skills Section
Your experience and skills section can be like this:
- Must be clear and easy to scan.
- Enriched with keywords.
- Must have relevance
Use bullet points, such as job description keywords, such as:
- Data Analysis
- Python
- SQL
- Project Management
6. Use Standard Job Titles and Terminology
Please do not be creative with the titles, so don't write something like “Marketing ninja”; instead, write clearly and concisely, like “Marketing specialist”.
ATS understands standard terms better than jargon.
7. Tailoring Standard Resume Heading for Each Job
Although it might seem like extra work, tailoring your resume significantly improves ATS performance.
Try changing some keywords and the skill order in your profile.
This is the real resume optimization for ATS.
Resume Optimization for ATS: Resume Formatting Rules You Must Follow
Best resume formatting for ATS: The ATS system mostly prefers DOCX and sometimes PDF. When in doubt, use DOCX.
ATS can read standard resume headings: Use a summary, work experience, educational qualifications, and relevant skills. These are the standard resume headings.
Some of the best font styles and sizes: Safe fonts such as Arial, Calibri, and Times New Roman work best. Keep sizes like 10.5 to 12 for text and 14 to 16 for headings. Simple bullets like “•” and “–”. Avoid symbols like “★” or “➤”.
Avoid Tables, Columns, Text Boxes, Graphics and Icons: ATS can't read columns, tables, images, logos, and charts. These confuse resume parsing.
One page vs two pages for a resume for ATS: ATS doesn’t care about length, but recruiters do. So, if entry-level, use 1 page, and if experienced, then you can use 2 pages.
Common Mistakes That Hurt ATS Resume Optimization
1. Keyword stuffing vs smart keyword placement
Don’t use “SEO SEO SEO”; instead, use “Led SEO strategy using keyword research and analytics”. Here, natural language wins.
2. Don't use fancy design templates
Heavily designed templates look good but fail in ATS. So avoid Canva-style designs, infographic structures, and two-column layouts.
3. Missing important sections
Never skip skill sets, work experience, and educational qualifications. ATS needs these to score you.
4. Inconsistent formatting
Don't mix fonts, sizes, and bullet styles. Consistency helps both ATS and humans.
5. Uploading resumes with incorrect file names
Don't save something like “resume_final_v7_reallyfinal.docx”; rather, you can save, for example, “John_Doe_Marketing_Manager.docx”.
6. Using Headers, Footers, or Images
ATS might ignore headers, footers, page numbers, and logos. Keep everything in the main body.
