How CMS usage is detected

Methodology

Company data

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.

Frequently asked questions

What is the most-used CMS among UK M&E contracting companies?
WordPress is the most-detected CMS among UK M&E contracting companies, with 77% share (1,992 of 2,587 companies with a detectable system), ahead of Wix (10.4%) and Squarespace (3.9%).
How many UK M&E contracting companies have a detectable CMS?

What is a CMS?
A CMS, or content management system, is the software used to create, edit and publish website content without rebuilding the site for each change. For UK M&E contracting companies, it is usually the layer behind service pages, project pages, enquiry forms and routine website updates.
How is CMS usage detected?
Firmbase crawls the public website of every actively-trading company in this scope and fingerprints the technologies present — scripts, widgets, booking and checkout flows. A company is attributed to a system when that system's signatures are found; systems with no public web footprint are not attributable, which is why every share figure on this page means share of companies with a detectable system.
Which has more UK M&E contracting companies, WordPress or Wix?
WordPress: 1,992 detected companies versus 270 for Wix, of the 2,587 UK M&E contracting companies with a detectable CMS.
What is the best CMS for UK M&E contracting companies?
