B2B Using All in One SEO in the UK: 3,345 Active Firms (2026)
B2B companies using SEO software sell products or services to other organisations, with UK public websites showing search-optimisation tooling.
For B2B suppliers, this SEO plugin sits close to the public website rather than the back office: it manages search metadata, XML sitemaps, indexing signals and content templates that help buyers find service pages, technical explainers and thought-leadership material. Adoption tends to signal an owned-channel sales motion, with marketing teams expected to generate enquiries rather than rely only on outbound or partner referrals. Typical users sell to corporate, public-sector or professional buyers through recurring, contract-based or account-managed relationships, so the website has to support qualification, evidence-gathering and conversion tracking before a salesperson enters the process.

UK adoption among B2B suppliers covers 3,345 actively trading companies. Within the detected SEO-tool mix for this sector, the plugin ranks third, at 8.7% across 38,594 sector sites. The registered-office skew is southern but not London-only: London accounts for 19.9% of the cohort, followed by the South East at 15.2%, the East of England at 10.4%, the North West at 10.2% and the West Midlands at 9.4%. Reported employment totals 625,661 people, so the adopters include sizeable operating businesses rather than only micro-sites.
B2B marketing obligations sit on the activity being carried out, not on a single sector licence. A supplier using SEO to capture enquiries may still be operating in financial services, telecoms, professional services, data processing or another regulated category, so website claims, forms and follow-up workflows need to reflect the relevant rulebook. The ICO position on PECR is especially practical for this cohort: electronic-mail rules differ for corporate subscribers, but organisations still must identify themselves and provide an opt-out route. UK GDPR continues to apply where business-contact data identifies a person, and live marketing calls require screening against CTPS and TPS where objections have been registered.
Adoption appears likely to remain tied to the wider website stack rather than being treated as a standalone procurement choice. B2B firms with lean marketing teams tend to keep familiar plugins if they are already embedded in content workflows, analytics tagging and form handling. Pressure comes from search-interface changes, privacy expectations and the need to attribute pipeline without over-collecting personal information. Over time, the category may tilt towards bundled website, analytics and consent tooling, while more mature users retain specialist SEO controls where organic search is a visible source of qualified enquiries.

Key facts
About 6% of the trading cohort reports turnover above £5M (201 of 3,345 firms) — the rest sits below that revenue band.
6% of the cohort was incorporated since 2022 (214 firms), so a sizeable share is in its first few filing cycles.
This SEO system is third by detected SEO-tool share among B2B suppliers, at 8.7% (3,345) of 38,594 companies with a detectable system; the two larger systems account for 78.6% (30,323) and 11.2% (4,323).
Every firm in the cohort runs the same content-management platform; 55.5% (1,856) also run web analytics, 42.7% (1,429) run bot-checking software and 21.0% (701) run tag-management tooling.
Construction and field services are the largest overlapping sector tags at 19.7% (659) and 19.4% (648), followed by advanced manufacturing at 14.8% (494).
London accounts for 19.9% (664) of the cohort, with the South East at 15.2% (509) and the East of England at 10.4% (349).
The ICO says B2B electronic mail to corporate subscribers does not need PECR consent, but senders must identify themselves, provide a valid opt-out address and still comply with UK GDPR where personal data is processed.

How All in One SEO 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. B2B companies are identified using Firmbase's semantic classification of company activity, built from filings, websites and registered SIC codes rather than SIC codes alone. The detected counts and share figures on this page are computed within that sector cohort, so "share" always means share of B2B companies with a detectable system — not of all UK companies.
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.
