Companies Using Site Kit in Portsmouth: 68 Active Firms (2026)
Companies running website analytics track public-site traffic and search performance across Portsmouth's business base.
Site Kit users tend to have marketing ownership of the public website rather than a separate web-operations function. The stack connects content management, search reporting and visitor measurement into the same administrative layer, so adoption usually signals an organisation that wants evidence on landing pages, enquiry paths and organic acquisition without commissioning a bespoke measurement build. Buyers are often owner-managed firms, local service providers or small regional operators where the website is still the main storefront. Engagements tend to be modest: configuration, consent settings, reporting templates and occasional agency support rather than a long enterprise implementation.

Portsmouth has 68 companies running Site Kit on public websites, a small adoption base with enough operating substance to be more than a collection of personal sites. Reported headcount totals 1,198 staff, so the footprint sits mainly among employer businesses rather than purely owner-maintained brochureware. The cohort fits the city’s mixed commercial base: local services, retail, hospitality, professional services, manufacturing and digital commerce all have reasons to track enquiries, bookings and search-led traffic through a low-maintenance website measurement layer.
Privacy and electronic-communications obligations are the main constraint for Site Kit users, because measurement tags can place cookies or process usage identifiers before a sales conversation has begun. Procurement is often light, but responsibility is split: marketing wants attribution, an external web agency may control the implementation, and a director or office manager may own consent wording. Companies selling into public bodies or regulated customers tend to face more questions about cookie choices, access permissions and where analytics reporting sits in the wider customer-record workflow.
Adoption appears likely to remain tied to content-managed websites and agency-supported marketing rather than large internal analytics teams. Portsmouth’s users tend to be practical operators, so churn may come from website rebuilds, consent-management changes and bundled reporting inside broader hosting or marketing packages. The scarcity of scale-up style users suggests fewer complex migrations, but also less tolerance for tools that need specialist maintenance. Over time, the stack may become less visible as analytics, search reporting and site administration are packaged together by web agencies and hosting providers.

Key facts
About 2% of the trading cohort reports turnover above £5M (2 of 68 firms) — the rest sits below that revenue band.
4% of the cohort was incorporated since 2022 (3 firms), so a sizeable share is in its first few filing cycles.
100.0% of Portsmouth companies in this cohort also run the same website platform, so the analytics plugin is attached to a common publishing base.
91.2% also run a separate web analytics tag, while 27.9% run a tag-management layer.
60.3% also run an SEO plugin and 47.1% run anti-spam or bot-checking technology.
Advanced Manufacturing accounts for 22.1% of sector tags, followed by Field Services & Trades at 17.6% and Construction at 10.3%.
Financial risk varies across the Portsmouth cohort: 20.6% sit in a weak band and 7.4% are distressed.

How Site Kit 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.
