Market leader by size
The leading WordPress plugins system shifts with company size: among UK B2B with under 10 employees, Site Kit leads at 34% of the 8,910 with a detectable system; among UK B2B with 10–50 employees, Site Kit leads at 33.5% of the 4,263 with a detectable system; and among UK B2B with over 50 employees, Site Kit leads at 40.1% of the 546 with a detectable system.
Under 10 employees
34% of band
Under 10 employees covers 8,910 detected companies, making it the largest employee band here. Site Kit is first at 34.0%, while competition comes from the same general-purpose, navigation, optimisation and page-builder systems seen in the overall market.
10–50 employees
33.5% of band
10–50 employees covers 4,263 detected companies, with Site Kit first at 33.5%. Mid-sized B2B sites in this band still split across analytics, menu, page-builder and image-optimisation plugins rather than a single specialist stack.
Over 50 employees
40.1% of band
Over 50 employees covers 546 detected companies, and Site Kit has a higher share here at 40.1%. The smaller base leaves more room for variation in secondary systems, but the first-ranked system is unchanged.
How WordPress plugins usage is detected
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.
