Understanding How Applicant Tracking Systems Evaluate Your Resume Content

Jul 10
4 min read

Applicant Tracking Systems (ATS) have become a standard tool for employers to manage the flood of resumes they receive. These systems scan, sort, and rank applications before a human ever sees them. If you want your resume to make it past this digital gatekeeper, you need to understand what ATS actually "see" when they read your resume. This post will break down how ATS work, what they look for, and how you can tailor your resume to improve your chances of getting noticed.

What is an Applicant Tracking System?


An Applicant Tracking System is software that helps employers collect, organize, and filter job applications. Instead of manually sorting through hundreds or thousands of resumes, recruiters use ATS to quickly identify candidates who meet specific criteria.


These systems scan resumes for keywords, skills, job titles, and other relevant information. They then rank or filter candidates based on how well their resumes match the job description. This process saves time but also means your resume must be formatted and written in a way that the ATS can understand.


How ATS Reads Your Resume


ATS software does not "read" resumes like a human. Instead, it scans the text and extracts data based on patterns and keywords. Here’s what happens behind the scenes:


  • Text Extraction: The ATS pulls text from your resume file. It works best with simple formats like .docx or .pdf but can struggle with images, graphics, or unusual fonts.

  • Keyword Matching: The system looks for keywords related to the job, such as specific skills, certifications, or job titles.

  • Parsing Information: ATS breaks down your resume into sections like contact info, work experience, education, and skills.

  • Ranking Candidates: Based on keyword matches and sometimes other criteria like years of experience, the ATS scores your resume.


Because ATS relies heavily on keywords and structure, resumes that are too creative or complex can confuse the system and cause important information to be missed.


What ATS Looks For in Resume Content


To pass through an ATS, your resume must include clear, relevant content that matches the job description. Here are the key elements ATS focuses on:


Keywords and Phrases


ATS scans for keywords that appear in the job posting. These often include:


  • Job titles

  • Required skills (e.g., "project management," "JavaScript")

  • Certifications or licenses

  • Industry-specific terms


For example, if a job posting asks for "data analysis" and "SQL," your resume should include those exact phrases if you have those skills.


Standard Section Headings


ATS software expects common headings to organize information. Use headings like:


  • Work Experience

  • Education

  • Skills

  • Certifications


Avoid creative headings like "My Journey" or "What I Bring" because ATS may not recognize them.


Simple Formatting


ATS can struggle with complex formatting. Use:


  • Standard fonts like Arial, Times New Roman, or Calibri

  • Bullet points for lists

  • Clear dates and job titles

  • Avoid tables, text boxes, graphics, or unusual characters


Contact Information


Make sure your contact details are easy to find and in a standard format. ATS looks for:


  • Full name

  • Phone number

  • Email address

  • Location (city and state)


Chronological Work History


Most ATS prefer resumes that list work experience in reverse chronological order, showing your most recent job first.


Common ATS Mistakes to Avoid


Many applicants unknowingly make errors that cause their resumes to be rejected by ATS. Here are some pitfalls to watch out for:


  • Using Headers and Footers: Important information placed in headers or footers may be missed.

  • Including Images or Logos: ATS cannot read images, so avoid logos or pictures.

  • Overusing Abbreviations: Spell out terms fully and include common abbreviations (e.g., "Certified Public Accountant (CPA)").

  • Ignoring Job Description Keywords: Tailor your resume for each job by including relevant keywords.

  • Submitting in Unsupported Formats: Stick to .docx or PDF files unless otherwise specified.


How to Optimize Your Resume for ATS


To improve your chances of passing ATS screening, follow these practical tips:


Match Keywords Naturally


Read the job description carefully and include keywords where they fit naturally in your resume. For example, if the job requires "customer relationship management," mention it in your skills or experience.


Use Standard Formatting


Keep your resume clean and simple. Use bullet points, consistent fonts, and clear section headings. Avoid tables or columns that can confuse the ATS.


Include a Skills Section


Create a dedicated section listing your relevant skills. This helps ATS quickly identify your qualifications.


Spell Out Acronyms


Write acronyms with their full names on first use, followed by the abbreviation in parentheses. For example, "Search Engine Optimization (SEO)."


Keep Contact Info Simple


Place your contact details at the top of the resume in plain text.


Test Your Resume


Use free online ATS simulators to see how your resume performs. These tools show how an ATS might parse your resume and highlight missing keywords.


Example of ATS-Friendly Resume Content


Here’s a brief example of how to format a section of your resume for ATS:

  • Content Marketing


This format uses clear headings, bullet points, and keywords from the job description.


Why Understanding ATS Matters


Knowing how ATS works helps you avoid common mistakes and tailor your resume to get noticed. Many qualified candidates never get interviews simply because their resumes are not ATS-friendly. By writing with ATS in mind, you increase your chances of moving forward in the hiring process.


Remember, ATS is just the first step. Once your resume passes the system, a real person will review it. Your resume still needs to be clear, professional, and compelling to land the interview.



Take the time to review your resume through the lens of an ATS. Use simple formatting, include relevant keywords, and organize your content clearly. This approach will help your resume stand out in a crowded job market and bring you closer to your next opportunity.
