Companies Using Sitecore

Our live crawl finds Sitecore on 13,870 domains, resolving to 7,081 identifiable companies. Named users include Adecco, Saudi Aramco, RTX, Huawei, ADP, IKEA, L'Oreal and IQVIA. The base is concentrated in regulated industries: insurance is the largest sector at 10.06%, with hospitals and health care second at 8.03%.

We detect 13,870 domains running Sitecore across our monthly crawl of live business domains. Company data could be matched for 7,081 of them (51.1%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 711 domains carried a Sitecore detection previously and no longer do.

Sitecore holds 0.09% of our CMS & Website Builders category and ranks 40th of 50 tracked technologies. Share is measured by distinct domains, so platforms with free self-serve distribution dominate: WordPress alone holds 62.27%. The metric captures how many sites run a platform, not the size or value of the organisations behind them.

By web footprint the largest alternatives in our CMS category are WordPress (9,519,706 domains), Wix (1,297,463), Squarespace (1,017,426), Webflow (262,281) and Joomla (226,312). For enterprise evaluations the closest functional comparison is Adobe Experience Manager, which serves the same multi-site estate requirement from a different industry base.

The United States leads with 3,611 matched companies (52.28%), followed by the United Kingdom (450), Australia (326), Canada (324) and the Netherlands (238). Australia and the Netherlands both index above the corpus norm, reflecting Sitecore's established implementation partner networks in those markets.

Organisations above 1,000 employees account for 19.20% of matched Sitecore customers, including 5.56% with more than 10,000 staff. The 1 to 10 bracket reads 28.90%, but for an estate platform that mostly reflects regional and brand domains resolving to small local entities rather than genuine small-business adoption.

Sitecore has an unusually established customer base. Companies founded before 1960 are the largest group at 26.06%, ahead of the 2000s at 15.99%, the 2010s at 15.37% and the 1990s at 14.87%. That age profile is consistent with the insurance, healthcare and banking concentration seen in the industry data.

Based on our matched customer data, the typical Sitecore customer is a US, UK or Australian organisation with more than 1,000 employees, founded before 1960, operating in insurance, healthcare or financial services. Sector is the strongest predictor: regulated industries with strict content governance requirements dominate the identified base.

We detect Sitecore on 13,870 domains as of our August 2026 crawl, of which 7,081 match to a named company. Because Sitecore runs multi-site estates, one organisation frequently accounts for several domains, so the number of distinct customers is lower than the domain count implies.

Insurance leads at 10.06% of matched customers, with Hospitals and Health Care at 8.03% and Financial Services at 6.63%. Grouping insurance, hospitals and medical practices puts healthcare and insurance at 21.36% combined, the sharpest sector concentration of any content platform we track.

We match several of Sitecore's own delivery signatures: its analytics and session cookies including SC_ANALYTICS_GLOBAL_COOKIE, its media and component paths such as /-/media/ and /_sitecore/, the SitecoreUtilities JavaScript object, and its cloud edge host. Multiple independent signals mean a detection reliably indicates a site served by the platform.

Google Tag Manager appears on 83.13% of Sitecore domains and Google Analytics on 65.61%. The most revealing figure is OneTrust at 42.25%, far above its corpus average, which follows directly from a customer base weighted toward insurance, healthcare and banking where consent management is a compliance requirement.

On the window we can observe, Sitecore has gained more from WordPress than it has lost to it: 55 domains arrived from WordPress against 27 moving the other way. These are small counts over a short observation period and should be read as direction rather than magnitude. In total 711 domains have dropped Sitecore since tracking began in March 2026.
