How to Optimise Your Resume for Applicant Tracking Systems

Applicant Tracking Systems (ATS) are sophisticated software that scan, parse, and rank resumes before they ever reach human recruiters. Understanding how these systems work is key to getting your resume noticed.

What is an ATS?

An ATS is software used by employers to manage job applications and screen resumes. These systems: - Scan resumes for keywords and skills - Parse information into structured data - Rank candidates based on job match - Filter out unqualified applicants

Step 1: Choose the Right Format

ATS-Compatible File Formats - **Best:** .docx (Microsoft Word) - **Good:** .txt (Plain text) - **Acceptable:** .PDF (with proper formatting) - **Avoid:** .pages, .doc, image files

Formatting Rules - Use standard fonts: Calibri, Arial, Times New Roman - Font size: 10-12pt for body, 14-16pt for headings - Single-column layout - No tables, columns, or text boxes - Margins: 0.5-1 inch on all sides

Step 2: Structure Your Resume Correctly

Standard Section Order 1. **Contact Information** (Top of page) 2. **Professional Summary** (2-3 lines) 3. **Work Experience** (Reverse chronological) 4. **Skills** (Technical and soft skills) 5. **Education** (Degrees, certifications) 6. **Optional:** Certifications, Projects

Contact Information Format

John Doe (555) 123-4567 | john.doe@email.com | LinkedIn.com/in/johndoe

Step 3: Optimise Keywords

Finding the Right Keywords 1. Copy the job description 2. Highlight required skills and qualifications 3. Include industry-specific terminology 4. Use action verbs relevant to your field

Keyword Density Best Practices - **Optimal:** 2.5-3.5% keyword density - **Too Low:** <1% (ATS won't recognise relevance) - **Too High:** >5% (May be flagged as keyword stuffing)

Example Keywords by Industry **Tech Industry:** Agile, Scrum, JavaScript, React, Node.js, AWS, DevOps **Healthcare:** HIPAA, Electronic Health Records, Patient Care, Medical Terminology **Finance:** Financial Modeling, Risk Assessment, Compliance, Bloomberg, Excel

Step 4: Write Achievement-Focused Content

Use the CAR/STAR Method - **C**ontext: Situation and environment - **A**ction: What you specifically did - **R**esult: Measurable outcome

**Before:** "Managed a sales team" **After:** "Led team of 8 sales representatives, implementing a new CRM system that increased team productivity by 35% and exceeded quarterly targets by 20%"

Step 5: Technical Optimisation

ATS Parsing Tips - Use standard section headers (Experience, Education, Skills) - Avoid special characters and symbols - Use bullet points (• or -) for lists - Include months and years for employment dates - Spell out acronyms the first time used

Common ATS Parsing Errors - ✗ "Jan 2020 - Present" - ✓ "January 2020 - Present"

  • ✗ "5+ years experience" - ✓ "5 years of experience"
  • Step 6: Final Optimisation Checklist
