Companies Using Yoast SEO in London: 8,895 Active Firms (2026)
London companies running SEO plugins use public websites to improve search visibility and manage metadata in a major UK digital advertising market.
Adoption of a mainstream SEO plugin usually sits with marketing, content and web operations teams rather than with engineering alone. The tool’s job is to make metadata, indexation settings, structured page content and search-led editorial routines manageable inside the website workflow. In practice, companies running the plugin tend to have an owned-content motion: lead-generation pages for B2B services, ecommerce category pages, recruitment content, or publishing operations that need repeatable on-page controls. It also suggests some go-to-market maturity, because search visibility, cookie notices, enquiry forms and campaign attribution usually need to be co-ordinated across internal teams or retained agencies.

London has 8,895 active trading companies running this SEO plugin, making the capital a sizeable adoption base for public websites using search-led content workflows. Reported employment totals 11,404 people among companies that disclose headcount. The profile is still small-business weighted: the median reported headcount is 5 and median turnover is about £520,000. Construction accounts for 11.3% of the cohort, field services and trades for 11.1%, real estate and property for 9.1%, healthcare providers for 6.6%, and wholesale and distribution for 6.3%.
Sites running SEO plugins and analytics are not generally subject to a sector-specific licence, but their marketing stack sits inside established UK rules. The ICO’s PECR guidance requires websites to tell users about cookies, explain what they do and why, and obtain consent before setting non-essential cookies or similar device-access technologies. Where tracking or analytics information is personal data, UK GDPR and the Data Protection Act also apply. The Advertising Standards Authority regulates advertising across media under the CAP Advertising Codes, so search landing pages, affiliate copy, paid search and social media promotion can be caught where they amount to marketing communications.
Adoption appears likely to remain tied to the broader content-management stack rather than becoming a stand-alone procurement decision. Smaller service firms tend to keep the plugin because it is familiar to agencies and easy to hand over between retained suppliers, while higher-headcount organisations are more likely to formalise governance around templates, redirects, consent settings and analytics tags. Migration pressure may come less from search itself than from bundled website platforms, privacy tooling and the consolidation of agency support. The cohort therefore looks sticky, but not immune to gradual substitution.

Key facts
About 6% of the trading cohort reports turnover above £5M (569 of 8,895 firms) — the rest sits below that revenue band.
7% of the cohort was incorporated since 2022 (706 firms), so a sizeable share is in its first few filing cycles.
The London cohort is CMS-dependent: 100.0% run the SEO plugin on the same content-management platform.
Analytics and conversion tracking sit close to the plugin signal, with 51.8% also running web-analytics tooling and 37.8% using tag-management tooling.

How Yoast 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.
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.
