Companies Using SEOmatic in London: 154 Active Firms (2026)
Companies running SEO technology automate metadata and content optimisation on public websites, with this cohort based across London.
Marketing, content and web operations teams tend to own this stack, rather than IT alone. Companies running this SEO automation stack usually need repeatable page templates, structured metadata and editorial controls across a public website, with agencies, in-house marketers or product teams sharing responsibility for changes. The buying centre points to digital acquisition rather than pure brand presence: property and construction firms use search to surface projects and listings, agencies manage client publishing workflows, and media publishers depend on discoverable article archives. Typical engagements look like website-platform maintenance rather than large change programmes, with recurring licences, implementation support and governance around who can change search-facing content.

London has 154 actively trading companies running this stack. They report 1,847 employees between them, which makes the adoption picture more SME-weighted than enterprise-led despite the public-web dependency implied by the technology. Sector mix tilts toward Real Estate & Property at 21.4% of the cohort and Construction at 20.8%, with Marketing Agency at 13.6% and Media & Publishing at 11.7% also present. Many firms fit more than one sector label, so these are better read as use-case signals than an exclusive split.
Regulation is indirect but not irrelevant. Public-page optimisation itself is not a licensed activity, yet the surrounding stack often touches consent banners, analytics tags, lead forms and customer-journey measurement. UK privacy and cookie-consent rules matter where visitor identifiers, enquiry details or profiling logic are used to test pages or attribute demand. Procurement also tends to be fragmented: marketing teams can buy the SEO layer, agencies may configure it, and web teams remain responsible for release control. That split makes audit trails, permissions and change approval more important than the licence category.
Adoption appears tied to content-management choices rather than a standalone SEO budget. That makes the installed base vulnerable to website rebuilds, agency changes and bundled optimisation features inside broader publishing suites. Companies with mature content operations may keep specialist automation where search traffic supports enquiries, bookings or editorial discovery; lighter users may rationalise the stack when templates are rebuilt. Consolidation is therefore likely to be quiet and procurement-led, not a visible land grab. The more durable users should be those with repeated page creation, clear ownership between marketing and web teams, and enough governance to treat metadata as operational infrastructure.
What’s in the file
One row per company, 50+ columns — everything below plus each company’s verified directors, from Companies House filings.
Company data
Verified directors — included
Active director count is the full Companies House board, so it can be higher than the number of names listed — we leave out nominee and formation-agent directors, who aren’t worth contacting. It’s blank for the small number of companies whose officers we haven’t fetched yet.
You’re charged per business, not per row. Where a business trades through several registered companies you get every one, and the Group Primary column marks one row per business — filter to those and the count matches your invoice. Rows sharing a website are not automatically one business: franchises and multi-site operators each count separately, and where names don’t prove a relationship we count them apart rather than guess.
Adoption by company size
Adoption of SEOmatic rises with company size across the trading companies in this cohort. 0% of the 532,485 companies with under 10 employees run SEOmatic (103 detected). 0.3% of the 15,364 companies with 10–50 employees run SEOmatic (42 detected). 0.5% of the 1,763 companies with over 50 employees run SEOmatic (8 detected). That is a 0.5% gap between the over 50 employees and under 10 employees bands.

Key facts
About 9% of the trading cohort reports turnover above £5M (14 of 154 firms) — the rest sits below that revenue band.
7% of the cohort was incorporated since 2022 (12 firms), so a sizeable share is in its first few filing cycles.
Every firm in the London cohort also shows the same content-management layer, with 100.0% overlap across 154 active firms.
Tag-management tooling appears on 46.1% of sites in the cohort, while 32.5% show web-analytics tooling.
Real Estate & Property is the largest sector tag at 21.4%, followed by Construction at 20.8% and Marketing Agency at 13.6%.
The cohort has 395 verified directors, which points to a buyer set suited to named-account research rather than broad volume prospecting.
Financial-health bands are mixed: 17.5% sit in the highest band, 20.8% are stable, and 12.3% are distressed.

How SEOmatic 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.
