You spend hours crafting the perfect CV. You tailor it to the job. You hit send — and hear nothing back. For most job seekers, this is the norm. But the reason isn't always that you're unqualified. Often, your CV never reached a human. Welcome to the world of ATS — Applicant Tracking Systems — the software that sits between your application and the hiring manager's inbox. This guide explains exactly how ATS works, how to check your CV's ATS score, and what changes will get you past the filter and into the interview pile.
What Is an ATS?
An Applicant Tracking System (ATS) is software used by employers to manage job applications. It automatically scans, filters, and ranks CVs before a recruiter ever looks at them. According to research by Jobscan, over 98% of Fortune 500 companies use ATS software. And it's not just big corporations — mid-sized companies and recruitment agencies increasingly rely on it too. When you submit a CV online, ATS typically:
- Parses your CV into structured data (name, skills, education, experience)
- Scans for keywords from the job description
- Scores your CV based on relevance
- Ranks it against other applicants
- Filters out CVs below a relevance threshold If your CV doesn't score well enough, it's archived automatically. A human never sees it.
How ATS Scores Your CV
Different ATS platforms (Workday, Greenhouse, Lever, Taleo, etc.) use different algorithms, but most score CVs based on:
1. Keyword Match
The most important factor. ATS compares the words in your CV to the words in the job description. The closer the match, the higher your score. If the job description says "project management" and your CV says "managing projects," that's a missed match. Exact phrase matching matters.
2. Skills Match
Many ATS systems maintain databases of skills. They check whether your listed skills match the required and preferred skills in the job posting.
3. Job Title Match
ATS often looks for your previous job titles matching roles listed as relevant experience. This is why tailoring your CV title matters.
4. Education Requirements
Some roles have minimum education requirements. ATS will filter out candidates who don't meet them automatically.
5. Years of Experience
If a role requires "5+ years of experience" and ATS calculates you have 3 years from your dates, it may filter you out — even if you're highly qualified.
Why Many CVs Fail ATS (Even Good Ones)
Here are the most common reasons a strong CV gets rejected by ATS:
Formatting Problems
- Tables and columns: Many ATS systems can't parse multi-column layouts. Text in the right column gets scrambled or lost.
- Headers and footers: Contact information in the header is sometimes missed.
- Images and icons: ATS can't read images. Logos, icons, and profile photos are invisible to it.
- Text boxes: Content inside text boxes is often ignored entirely.
- Unusual fonts: Stick to standard fonts (Arial, Calibri, Georgia, Times New Roman).
Wrong File Format
PDF is generally safe, but some older ATS systems parse .docx files better. When in doubt, submit both if the system allows it — or check what the job posting asks for.
Missing Keywords
Using synonyms instead of the exact terms in the job description. If they say "KPIs" and you write "key performance indicators," you might miss the match (though better ATS systems handle this).
Generic CV
Sending the same CV to every job. ATS is designed to reward relevance — a tailored CV will always outperform a generic one.
How to Use an ATS Resume Checker
An ATS resume checker compares your CV against a specific job description and gives you a match score and improvement recommendations. Here's how to use one effectively: Step 1: Copy the job description you're applying to. Step 2: Upload or paste your CV into the ATS checker. Step 3: Review your score and the keyword gap analysis. Step 4: Add missing keywords naturally into your CV (don't keyword-stuff — ATS can detect it, and humans will too). Step 5: Re-check until your score improves, then apply. CVmake's free ATS checker lets you paste a job description and instantly see how well your CV matches — with specific suggestions for improvement.
10 Ways to Improve Your ATS Score
1. Mirror the Job Description Language
Read the job posting carefully. Note the exact phrases used for skills, responsibilities, and qualifications. Use those exact phrases in your CV — especially in your skills section and work experience bullet points.
2. Use a Clean, Single-Column Layout
Avoid tables, columns, and text boxes. A simple top-to-bottom layout parses most reliably across all ATS platforms.
3. Use Standard Section Headings
ATS looks for familiar headings. Use:
- Work Experience (not "Career History" or "Professional Journey")
- Education (not "Academic Background")
- Skills (not "Things I Know")
4. Include Both Spelled-Out and Abbreviated Forms
If a skill has a common abbreviation, include both. E.g., "Search Engine Optimisation (SEO)" — this covers both keyword variations.
5. Put Keywords in Context
Don't just list keywords — embed them in achievement-based bullet points. "Managed SEO strategy" is better than just listing "SEO" in a skills list.
6. Tailor Your Job Title
If your actual title was "Growth Ninja" but you're applying for a "Digital Marketing Manager" role, consider whether you can clarify your title in context (e.g., "Growth Ninja (Digital Marketing Manager)").
7. Quantify Your Achievements
ATS systems increasingly score for specificity. "Increased sales by 35%" scores better than "improved sales performance."
8. Include a Skills Section
A dedicated skills section gives ATS a concentrated area to find keyword matches. List both hard skills (tools, technologies) and relevant soft skills.
9. Save as the Right File Type
Save as .pdf or .docx — check the job posting for preferences. Avoid .pages, .odt, or image files.
10. Don't Hide Keywords in White Text
This old trick (adding white text keywords to fool ATS) is detected by modern ATS software and will get your application flagged or rejected entirely.
What ATS Score Should You Aim For?
Most experts recommend aiming for a 75–85%+ keyword match before submitting. Below 60%, your CV is unlikely to make it through automated screening for competitive roles. That said, ATS score isn't everything. A high-scoring CV still needs to impress the human who reads it after the filter. Don't sacrifice readability for keyword density.
ATS vs. Human Review: Finding the Balance
The best CVs are optimised for both:
| For ATS | For Humans |
|---|---|
| Exact keyword matches | Clear, readable structure |
| Standard section headings | Compelling achievements |
| Clean formatting | Strong opening statement |
| Relevant skills listed | Personality and fit |
| Correct file format | No typos or errors |
Treat ATS optimisation as a filter to get through — and human optimisation as the thing that gets you the job.
