Read from the source, not self-reported
Every number on this page can be traced to a page we crawled or a posting we read. Full methodology →
- Job postingsRead hourly from the applicant tracking systems behind British career sites. A tool counts when the employer's own text names it as the team's system.
- CountryFrom the company's own website: imprint, address, phone prefix and language, with a confidence score. Not the posting's location.
- Website and DNSScripts and embeds on the company's pages, plus SPF, DKIM, MX and CNAME records of its domain that point at the vendor.
- ExclusionsJob boards, portals and aggregators are kept out of company lists.
