Companies Using AddThis in Leeds: 73 Active Firms (2026)
Leeds companies running social sharing tags operate websites that encourage visitor content sharing and engagement measurement across the metropolitan economy.
Marketing, e-commerce and website teams are the usual buying centres for this kind of tag, rather than central IT alone. The script adds sharing controls and engagement signals to public webpages, so its presence tends to indicate an organisation that treats the website as a measurable acquisition or retention channel. In Leeds, that can mean trade-services firms, manufacturers, distributors, automotive retailers and online sellers with content or catalogue pages worth promoting. Adoption also implies some budget for tag management, consent tooling and campaign reporting, even where the internal team is small and implementation is handled by an agency or part-time digital role.

Leeds has 73 actively trading companies running this social-sharing and engagement-tracking tag, a narrow adoption cohort rather than a proxy for all local website operators. The employment footprint is visible rather than trivial: reported headcount totals 1,545 across the cohort. Sector mix points towards practical, transaction-led websites, with Field Services & Trades and Advanced Manufacturing each accounting for 15.1% of the local cohort, and Wholesale & Distribution plus Automotive Retail each at 13.7%. Co-occurring website infrastructure is mostly mundane: tag managers, content-management systems, mapping widgets, analytics, anti-bot checks and video embeds appear alongside the sharing layer.
PECR and UK GDPR make these deployments a compliance as well as marketing-operations choice. ICO guidance requires website operators to tell users when cookies or similar technologies are present, explain their purpose, and obtain consent before storing or accessing information on a device. Non-essential tracking should not be set before consent on the homepage, and consent needs a clear positive action; anonymity does not take the activity outside PECR. Where identifiers become personal data, UK GDPR and the Data Protection Act also apply. IAB UK adds market-structure context through its work on digital advertising expenditure, which is treated as the official measure of the UK digital advertising market.
Adoption appears to be moving from simple share widgets toward managed consent, tag hygiene and tighter attribution controls. Smaller Leeds adopters tend to keep these scripts because they are low-friction additions to content and commerce sites, while larger operators are more likely to rationalise overlapping tags as privacy reviews and performance budgets bite. Older social-sharing code may be retired when consent platforms, analytics tools and site-build workflows bundle similar functions. The pattern looks less like a fresh build-out and more like gradual pruning: fewer orphaned tags, clearer consent journeys, and more scrutiny of what engagement tracking still earns its place.
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 AddThis rises with company size across the trading companies in this cohort. 0.1% of the 56,251 companies with under 10 employees run AddThis (51 detected). 0.6% of the 2,891 companies with 10–50 employees run AddThis (18 detected). 1.3% of the 307 companies with over 50 employees run AddThis (4 detected). That is a 1.2% gap between the over 50 employees and under 10 employees bands.

Key facts
About 8% of the trading cohort reports turnover above £5M (6 of 73 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.
35.6% of the Leeds social-sharing tag cohort also runs a tag-management tool, suggesting the tag usually sits inside a managed marketing stack rather than being the only website script.
34.2% also use a content-management platform, while 27.4% also run web analytics tags.
Field services and trades and advanced manufacturing each account for 15.1% of the cohort, ahead of wholesale and distribution and automotive retail at 13.7% each.
The ICO says PECR regulation 6 requires website operators to explain cookies and similar technologies and obtain consent before storing or accessing information on a user’s device.
In 2024, 68% of UK businesses had a website and 77% handled digitised data of any type.

How AddThis 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.
