The Complete Guide to ATS Resume Optimisation: Getting Past the Digital Gatekeeper

In today's competitive job market, a sobering truth faces every job seeker: up to 75% of qualified candidates are rejected by applicant tracking systems (ATS) before a human recruiter, such as a hiring manager, even reviews their CV. This invisible digital gatekeeper filters resumes, making an ATS optimised CV essential for anyone navigating the modern hiring process. By tailoring your resume to meet ATS requirements, you significantly increase your chances of landing your dream job.

What Is ATS Resume Optimisation?

ATS resume optimisation refers to the process of creating a CV that aligns with the specifications of applicant tracking systems. These systems are used by large companies, including Fortune 500 companies, as well as small and medium enterprises, to streamline the recruitment process. By focusing on ATS-friendly resume formats and integrating relevant keywords, you ensure your application not only passes the system's filters but also resonates with human recruiters.


Understanding How ATS Works

To create an ATS optimised CV, it's crucial to understand how ATS systems operate:

1. Keyword Matching

ATS software scans resumes for keywords from the job description. The absence of the right keywords can result in your resume ranking poorly. Keywords should represent your skills and qualifications relevant to the job title you're applying for.

2. Data Parsing

The ATS breaks down the resume's content into fields like work experience, education, and key skills. Using a standard resume template and proper section titles ensures your data is correctly categorised.

3. Scoring and Ranking

After parsing, the ATS assigns a score based on how well your resume matches the job description. High-scoring resumes move forward to the hiring manager, while low-scoring ones are filtered out.


Strategies for ATS Resume Optimisation

1. Master Keyword Optimisation

  • Carefully read the job posting and identify resume keywords.
  • Use keywords in the context of accomplishments (e.g., "Led a team of 10 in a successful customer relationship management project").
  • Avoid keyword stuffing, as it can make your resume unreadable for human reviewers.

2. Focus on Formatting

An ATS-friendly resume format is critical:

  • Use a standard font like Arial, Calibri, or Times New Roman.
  • Avoid complex designs, text boxes, and embedded images that may confuse the ATS.

3. Structure Your Resume Strategically

  • Include all important information in a logical sequence: contact information, summary, skills section, professional experience, and education section.

  • Quantify achievements using numbers and metrics to add specificity.

4. Quantify Your Achievements

Numbers and metrics catch both digital and human eyes:

  • Lead with strong action verbs
  • Include specific, measurable results (e.g., "Increased customer satisfaction by 35%")
  • Highlight relevant achievements that demonstrate your impact

Common ATS Optimisation Mistakes to Avoid

  • Don't repeat keywords unnecessarily
  • Avoid creating "invisible" text by matching font colour to the background
  • Maintain natural, readable language throughout

2. Over-Design

Keep the design simple and functional:

  • Avoid tables, graphics, and images, and non-standard fonts
  • Skip fancy formatting and creative layouts
  • Refrain from using headers, footers, and special characters.
  • Don't use text boxes or multiple columns

3. Generic Applications

One-size-fits-all approaches rarely succeed, tailor each application to the job title and specific job description. Submitting the same resume for multiple roles rarely succeeds:

  • Customise each resume for the specific job
  • Align your experience with the role's requirements
  • Adjust keywords based on each job description
