You've tailored your CV, written a strong cover letter, and hit apply — then heard nothing. It's frustrating, and often it's not your fault. Many applications never reach a human at all. Here's why, and what you can do about it.
An Applicant Tracking System (ATS) is software used by employers and recruiters to manage job applications. When you apply for a role online, an ATS often scans your CV before a human ever sees it. The system filters, ranks, and sometimes rejects applications automatically based on keywords, formatting, and relevance to the job description.
In the UK, the majority of medium- and large-sized employers use some form of ATS, which means your CV needs to be optimised not just for humans but also for the software.
Why Do CVs Get Rejected by an ATS?
There are several common reasons an ATS might filter out your CV:
- Missing keywords: The ATS looks for specific terms from the job description. If your CV doesn't include them, it may be ranked lower or rejected.
- Complex formatting: Tables, columns, graphics, headers, and footers can confuse ATS software and cause it to misread your information.
- Wrong file format: Some ATS systems struggle with PDFs. A Word document (.docx) is often the safest choice unless stated otherwise.
- Unusual section headings: Stick to standard headings like "Work Experience", "Education", and "Skills" rather than creative alternatives.
- Images or logos: ATS software cannot read text embedded in images, so avoid using them in your CV.
How to Make Your CV ATS-Friendly
Follow these steps to give your CV the best chance of passing through an ATS:
- Tailor your CV for each role. Read the job description carefully and use the same language. If the job asks for "stakeholder management", use that exact phrase — not "managing relationships".
- Use a clean, simple layout. Single-column formats with clear headings are easiest for ATS to parse. Avoid tables, text boxes, and decorative elements.
- Include a skills section. List relevant technical skills and tools explicitly. This makes it easy for the ATS to identify your competencies.
- Use standard fonts. Stick to Arial, Calibri, or Times New Roman. Unusual fonts can cause parsing errors.
- Save as .docx unless told otherwise. Check the job listing — if no format is specified, Word format is the safer bet.
- Spell out acronyms. Write "Search Engine Optimisation (SEO)" rather than just "SEO" to cover both variations the ATS might search for.
Keywords: The Most Important Factor
Keywords are the single biggest factor in ATS success. To find the right ones, read the job description and highlight the skills, qualifications, and tools mentioned most frequently. Then make sure those exact terms appear naturally throughout your CV – in your summary, work experience, and skills sections.
Don't "keyword stuff" – that is, don't add irrelevant keywords or hide white text on a white background. Modern ATS systems and human reviewers can detect this, and it will disqualify you.
Does Beating the ATS Guarantee an Interview?
Not on its own, but it does help get your CV in front of a human. Once a recruiter sees your application, the quality of your experience, achievements, and presentation takes over. That's why it's important to have a CV that works for both the ATS and the reader.
