Companies Using Site Kit in Leeds: 224 Active Firms (2026)
Companies using website analytics tooling measure site traffic and search visibility across Leeds and its surrounding metropolitan area.
Adoption of this analytics layer usually sits with marketing, web and commercial operations rather than core IT. Companies running it tend to have a public content-management estate, search traffic they want to monitor, and enough inbound demand to justify regular reporting on page performance, form conversion and search visibility. The buying centre is often a small marketing team or an agency-managed website function, not a dedicated analytics department. In practice, that points to organisations using their sites for lead generation, ecommerce support, recruitment or customer service, with engagements likely to be modest software subscriptions plus periodic agency or freelancer support.

Across Leeds and its surrounding metropolitan area, 224 companies running this analytics stack are actively trading. The reported employment footprint is 2,569 people across 117 firms, so the visible base is a set of small teams with a few larger operating businesses rather than a pure micro-company tail. The commercial centre of gravity is not purely start-up: 17 firms report turnover above £5M, while only 10 were incorporated since 2022. Typical adopters are therefore established website operators with a reason to monitor search-led demand, not only newly incorporated digital-first firms.
Privacy and procurement work is likely to be ordinary but not trivial. Companies running this stack usually place analytics inside a content-managed website, often alongside form handling, tag deployment, anti-spam checks and delivery infrastructure. That means visitor identifiers, enquiry content and agency permissions need governance, even when the website is not the core operating system. Leeds adopters span trades, construction, distribution, manufacturing and healthcare providers, so the risk profile varies from simple lead capture to more sensitive customer communications. For researchers, the useful distinction is between firms using analytics as a lightweight marketing control and those embedding it into paid acquisition, recruitment or service workflows.
Adoption appears tied less to experimentation than to basic website operating discipline. Many firms in the cohort look like established regional businesses with agency-managed sites, so churn in the stack may come from redesign cycles, consent tooling changes and consolidation of marketing dashboards rather than from wholesale platform replacement. Smaller operators tend to keep the default analytics layer if it continues to answer search and traffic questions; more mature teams are more likely to add governance around tags, attribution and customer journeys. The direction is therefore incremental: tighter consent controls, fewer unmanaged scripts and more bundling of search, content and conversion reporting.

Detected companies are joined to UK Companies House records and XBRL accounts data. Revenue and headcount figures come from the most recent filed accounts; where the company has not filed, values are estimated using a model trained on filed history and peer benchmarks and are labelled as estimates.
Detection
Firmbase crawls the public website of actively-trading UK companies and fingerprints the technologies present: tracking scripts, embedded forms, chat widgets, CMS markers and similar signatures. A company is included in this list when one or more of the technology's signatures are found on its site; closely-related variants of the same product are grouped under one name. Detection covers what is visible on the public web — a company using the technology purely internally, with no website footprint, will not appear. Counts are therefore a conservative floor, not a ceiling.
Freshness
Websites are re-crawled on a rolling basis and the underlying company data is refreshed from Companies House continuously; filings appear within days of submission. The list and its statistics are regenerated when the detected cohort moves meaningfully. You can see the last-updated timestamp near the top of the page.
