If you're applying for jobs and not hearing back, your CV might not be getting rejected by humans. It might not be reaching them at all.
What is an ATS?
Most medium and large employers now use applicant tracking systems (ATS) to manage the volume of applications they receive. These are software platforms that collect, sort and filter CVs before a recruiter ever opens them. They scan for keywords, check formatting, and can even rank candidates based on how well their application matches the job description.
The UK ATS market has grown significantly in recent years and adoption continues to rise, particularly among larger organisations. According to research by Tracker RMS, 88% of employers believe they have lost highly qualified candidates because their CVs were not formatted in a way the ATS could read correctly.
Why CVs fail ATS screening
The most common reasons a CV gets filtered out have nothing to do with the candidate's experience. They are almost always formatting or keyword issues.
Graphics, tables, headers and footers, text boxes, unusual fonts and multi-column layouts can all confuse ATS parsing software. The system reads the document as code, not as a human would. If it cannot extract your job titles, dates and skills cleanly, your application may be ranked lower or missed entirely regardless of your suitability for the role.
The other common failure is keyword mismatch. ATS platforms are configured by recruiters to search for specific terms from the job description. If you call something "people management" and the job spec says "team leadership," the system may not make the connection.
How to make your CV ATS-friendly
The good news is that ATS optimisation does not always require a dramatic overhaul. A few targeted changes can make a big difference.
Use a clean, single-column layout with standard section headings: Work Experience, Education, Skills. Avoid tables, text boxes and images. Save your CV as a Word document or a text-based PDF rather than a scanned image.
Mirror the language of the job description. If the role specifies "stakeholder management," use that phrase rather than a synonym. Read the job posting carefully and make sure the key terms appear naturally in your CV where they are genuinely relevant to your experience.
Keep your contact details in the main body of the document rather than the header or footer, as some ATS platforms skip these areas entirely.
ATS optimisation does not mean keyword stuffing
A common mistake is overloading a CV with keywords in an attempt to game the system. Modern ATS platforms are increasingly sophisticated and can detect unnatural repetition. More importantly, once your CV reaches a human reader, it needs to hold up on its own merits.
The goal is a CV that passes the system and impresses the person who ends up reading it. Those two things are not in conflict. A well-structured, clearly written, achievement-led CV will do both.
The bottom line
ATS is one filter in a multi-stage process, but it is the first one, and failing it means the rest of your CV never gets seen. Getting the basics right costs nothing except attention to detail.
