Free ATS CV checker: how UK applicant tracking systems read your CV

Most large UK employers run your CV through an Applicant Tracking System (ATS) before a person reads it. If the software can't parse your CV cleanly, a strong candidate can be filtered out for reasons that have nothing to do with ability. Understanding what the machine does first is half the battle.

What an ATS actually is

An ATS is recruitment software that ingests every application, extracts the text, and stores it as structured fields — name, contact, work history, education, skills. Recruiters then search and filter that database. Common systems you'll meet in the UK include Workday, Greenhouse, SmartRecruiters, iCIMS and Taleo.

Two things follow from this:

1. Your CV is parsed into text. Anything the parser mangles is effectively lost.
2. Recruiters search by keyword. If your CV doesn't contain the words they search for, you don't surface.

What breaks ATS parsing

These are the usual culprits, in rough order of how often they cause damage:

• Tables and multi-column layouts. Many parsers read left-to-right across the whole page, scrambling two-column CVs into nonsense. Use a single-column layout.
• Text in headers/footers. Some ATSes ignore them entirely. Don't put your contact details only in the header.
• Images, icons and text boxes. Skills shown as little graphics or rating bars usually extract as nothing.
• A photo. UK convention is no photo anyway; some systems also choke on the layout around it.
• Unusual fonts or heavy styling. Stick to standard fonts and real text, not text-as-image.
• Wrong file type. A clean, text-based PDF or .docx is safest. Avoid exporting a CV as a flat image.

What an ATS rewards

• A clear single column with conventional section headings ("Work Experience", "Education", "Skills").
• Real keywords from the job description, used naturally. If the advert says "stakeholder management" and you've done it, write "stakeholder management" — not a clever synonym the recruiter won't search for.
• Standard date formats so your timeline parses correctly.
• Plain text, selectable and copyable, throughout.

Keyword-matching is about being findable, not stuffing. Name the skills you genuinely have, the way the employer names them.

A quick checklist
