ATS CV Tips: How to Optimise Your CV for Applicant Tracking Systems

Most CVs are rejected by software before a human ever reads them. Learn exactly how ATS works and what to do about it.

What Is an ATS?

An Applicant Tracking System (ATS) is software used by employers to receive, store, filter, and rank job applications. Over 95% of large companies — and a growing number of medium-sized businesses — use ATS software as the first stage of their hiring process. Workday, Greenhouse, Lever, iCIMS, Taleo, and SmartRecruiters are among the most widely used platforms.

When you submit your CV online, it is parsed by the ATS. The system extracts your contact information, work history, education, and skills from the document text. It then scores your application against the job description using keyword matching and other signals. CVs that score below a threshold may never be seen by a human recruiter at all.

This isn't a hypothetical risk. For competitive roles at large companies, it's the norm. Understanding how ATS works — and how to work with it — is one of the most important things a job seeker can do in 2026.

How ATS Systems Score Your CV

Different ATS platforms use different algorithms, but the core logic is similar across most systems:

The 6 Most Important ATS Optimisation Tips

1
Use keywords from the job description — exactly

Read the job description carefully, especially the "Requirements" and "Essential skills" sections. Note the specific phrasing: if the JD says "demand generation", use "demand generation" — not "lead generation" or "inbound marketing". ATS systems often cannot reliably match synonyms, and the ones that can still score exact matches higher. See our CV keywords guide for a full breakdown of how to extract and use keywords.

2
Embed skills in your experience section, not just a list

"Python" in a skills list scores lower than "Built a Python ETL pipeline processing 2M daily records" in your experience section. Always try to use your key skills in the context of achievements and responsibilities. This satisfies both the ATS (which sees the keyword in context) and the human recruiter (who sees evidence, not just a claim).

3
Use a clean, single-column format

No tables, text boxes, columns, or graphics. ATS parsers are fundamentally text-extraction tools — they pull content from a document and classify it. Complex layouts with multiple columns, text in table cells, or information inside graphics may be partially or completely missed by the parser. A single-column layout with clear section headings is the safest choice.

4
Save as a standard PDF

Unless the job posting explicitly requests a Word document (.docx), save your CV as a PDF. Most modern ATS platforms parse PDFs cleanly. PDF ensures your formatting stays intact regardless of the device or software used to open it. One important exception: avoid image-based PDFs (i.e., a scanned document saved as PDF) — these contain no extractable text and will fail ATS parsing entirely.

5
Use standard section headings

Stick to universally recognised headings: "Work Experience" (not "Career Journey"), "Education" (not "Academic Background"), "Skills" (not "Toolkit"), "Certifications" (not "Credentials"). ATS parsers are trained on millions of CVs and expect these labels. Creative alternatives may confuse the parser and cause your content to be ignored or miscategorised.

6
Don't keyword-stuff

Listing keywords randomly, repeating them excessively, or inserting them in white text (invisible to humans but technically present for ATS) is a black-hat tactic that no longer works reliably. Modern ATS platforms are more sophisticated, and some penalise obvious keyword stuffing. More importantly, a human reads every CV that passes ATS screening — a keyword-stuffed CV will fail that review. Integrate keywords naturally and meaningfully.

Which Industries Use ATS Most?

Virtually all large employers use ATS, but the practice is most universal in:

Smaller businesses — especially startups with fewer than 50 employees — often review CVs manually. But once a company grows to a certain size, manual screening becomes impractical and ATS adoption follows quickly.

Frequently Asked Questions

Do all companies use ATS?
Most medium-to-large companies do. Research suggests 95%+ of Fortune 500 companies use ATS software. Startups and small businesses with fewer than 50 employees often review CVs manually, but this becomes increasingly rare as organisations scale. When in doubt, treat every application as though it will be ATS-screened first.
Will ATS reject my CV if I'm missing one keyword?
Not usually. ATS systems produce a score based on overall keyword coverage, not a binary pass/fail on each term. If you're missing one keyword from a long list of requirements, you'll score slightly lower but won't automatically be rejected. However, if you're missing several of the most frequently mentioned or explicitly "essential" keywords, you're likely to fall below the threshold. Aim to match 70%+ of the required skills listed in the job description.
Should I have a separate skills section for ATS?
Yes — a dedicated skills section helps ATS parsers explicitly catalogue your competencies. Some ATS platforms have a specific skills parser that scans a recognised "Skills" section. But don't rely on your skills section alone — also embed key skills in your experience bullets, where they carry more evidential weight.
Does ATS care about CV length?
Not directly. ATS scoring is based on keyword and content matching, not page count. However, a longer CV that covers more relevant experience and naturally uses more of the JD's keywords may score higher. Don't pad your CV to increase length — but don't artificially cut it either if you have genuinely relevant content.
Can I lie or exaggerate to beat ATS?
No. ATS is just the first filter. Human reviewers read every CV that passes ATS screening, and interviewers will probe and test every claim you make. Adding keywords for skills or experience you don't have is a strategy that may get you an interview but will unravel quickly once you're in the room. Only include keywords that reflect genuine, demonstrable experience.
