Applicant Tracking Systems (ATS) are software applications that employers use to manage job applications and screen candidates. Understanding how these systems work is crucial for job seekers, as 75% of resumes are rejected by ATS before a human ever sees them. This guide will help you optimize your resume to pass through ATS filters and reach human recruiters.

Pro Tip: While Resume Tailor automatically optimizes your resume for ATS compatibility, understanding these principles will help you create better base resumes and make more informed editing decisions.

Understanding ATS Systems

ATS software scans resumes for specific keywords, formatting, and qualifications to determine which candidates are the best match for a job. Here's how the process typically works:

  1. Resume Parsing: The ATS extracts information from your resume and organizes it into categories (contact info, work experience, education, skills, etc.)
  2. Keyword Matching: The system compares your resume against the job description, looking for relevant keywords and phrases
  3. Ranking: Candidates are scored and ranked based on how well their resumes match the job requirements
  4. Filtering: Resumes that don't meet minimum requirements or score thresholds are filtered out
  5. Human Review: Only the top-ranking resumes are forwarded to human recruiters for review

ATS Compatibility Score

Resume Tailor provides an ATS Compatibility Score for each tailored resume. This score indicates how well your resume will perform with ATS systems:

Poor (0-60%) Good (61-80%) Excellent (81-100%)
  • 90-100%: Excellent - Your resume is highly optimized and likely to pass through ATS filters
  • 75-89%: Good - Your resume is well-optimized but could benefit from minor improvements
  • 60-74%: Fair - Your resume needs several improvements to perform well with ATS systems
  • Below 60%: Poor - Your resume is likely to be filtered out by ATS systems

Key Formatting Guidelines for ATS

DO

  • Use standard resume sections (Experience, Education, Skills)
  • Use common section headings that ATS can recognize
  • Use standard fonts (Arial, Calibri, Times New Roman)
  • Use bullet points for listing achievements and responsibilities
  • Save your resume as a .docx or .pdf file

DON'T

  • Use tables, text boxes, or columns
  • Include headers, footers, or page numbers
  • Use graphics, charts, or images
  • Use fancy fonts or creative formatting
  • Submit your resume as a .jpg, .png, or non-standard file type
Important: Even if your resume looks visually appealing to humans, complex formatting can confuse ATS systems and cause your resume to be rejected. Prioritize ATS compatibility over visual design.

Keyword Optimization Strategies

Keywords are critical for ATS success. Here's how to optimize your resume with the right keywords:

1. Identify Relevant Keywords

The most important keywords are found in the job description:

  • Hard Skills: Technical abilities, software proficiency, certifications
  • Soft Skills: Communication, leadership, problem-solving
  • Industry Terminology: Field-specific jargon and acronyms
  • Action Verbs: Words that describe your accomplishments (achieved, implemented, managed)

2. Use Keywords Naturally

DO

Good Example:

"Implemented Agile project management methodologies to improve team efficiency by 30%, reducing product development time from 6 months to 4 months."

DON'T

Bad Example:

"Agile project management, team efficiency, product development, leadership, communication, problem-solving, strategic planning, cross-functional teams."

3. Include Both Acronyms and Full Terms

Some ATS systems may search for either the acronym or the full term:

  • Good Example: "Certified Project Management Professional (PMP) with 5 years of experience"
  • Good Example: "Proficient in Search Engine Optimization (SEO) techniques"

4. Create a Skills Section

Include a dedicated skills section that lists relevant keywords in an organized manner:

  • Technical Skills: Python, SQL, Tableau, AWS, Docker
  • Industry Knowledge: Digital Marketing, Content Strategy, SEO, SEM
  • Soft Skills: Team Leadership, Client Communication, Problem-Solving

Resume Section Organization

Proper section organization helps ATS systems correctly categorize your information:

1. Contact Information

  • Place at the top of your resume
  • Include name, phone, email, and LinkedIn URL
  • Avoid icons or special characters

2. Professional Summary/Objective

  • Keep it concise (3-5 lines)
  • Include relevant keywords from the job description
  • Highlight your most impressive qualifications

3. Work Experience

  • List in reverse chronological order (most recent first)
  • Include company name, job title, location, and dates (MM/YYYY format)
  • Use bullet points for accomplishments and responsibilities
  • Start bullets with strong action verbs
  • Include metrics and quantifiable achievements when possible

4. Education

  • Include degree, institution name, location, and graduation date
  • List relevant coursework, honors, or academic achievements
  • Place education after experience (unless you're a recent graduate)

5. Skills

  • Organize skills into categories for better readability
  • Prioritize skills mentioned in the job description
  • Include proficiency levels when relevant

6. Additional Sections (as needed)

  • Certifications and Licenses
  • Professional Associations
  • Publications or Patents
  • Languages
  • Volunteer Experience
Pro Tip: Resume Tailor automatically organizes your resume sections in the optimal order for ATS compatibility while ensuring the most relevant information appears prominently for human reviewers.

Testing Your Resume Against ATS

Even with Resume Tailor's optimization, it's good practice to test your resume against common ATS systems:

1. Use Resume Tailor's ATS Preview

Resume Tailor provides an "ATS View" that shows how your resume will appear to an ATS system:

  1. After tailoring your resume, click the "ATS View" tab
  2. Review how your information is parsed and categorized
  3. Check for any missing or incorrectly categorized information
  4. Make adjustments as needed

2. Check Keyword Density

Resume Tailor shows you which keywords from the job description are included in your resume:

  1. Look at the "Keyword Analysis" section
  2. Green keywords are included in your resume
  3. Red keywords are missing from your resume
  4. Add missing keywords where relevant

Aim for a keyword match rate of at least 80% for best results.

3. Test with Multiple Job Descriptions

If you're targeting similar roles at different companies:

  1. Tailor your resume for multiple job descriptions
  2. Look for common keywords across all tailored versions
  3. Create a "master" resume that includes these common keywords
  4. Use this master resume as your starting point for future tailoring

Common ATS Myths Debunked

FACT

ATS systems are becoming more sophisticated and can now understand context, synonyms, and related terms. However, exact keyword matches are still important.

MYTH

You need to stuff your resume with keywords to pass ATS filters. This can actually hurt your chances, as modern ATS can detect keyword stuffing.

FACT

Both PDF and DOCX formats can work well with modern ATS, but it depends on the specific system. When in doubt, have both formats ready.

MYTH

You must keep your resume to one page to pass ATS. Most ATS systems don't care about length, though human recruiters might prefer concise resumes.

FACT

ATS systems are just the first hurdle - your resume still needs to impress human recruiters once it passes the ATS filter.

MYTH

White text keywords (hiding keywords by making them white) will help you pass ATS. This is considered deceptive and many ATS systems can detect this trick.
