Companies Using Siteimprove

Siteimprove Usage Statistics

Siteimprove reads 8,921 domains on our June 2026 rollup, 12,259 in July and 12,493 in August. Three points cannot carry a growth rate, and this movement is coverage rather than adoption. The crawled domain set turns over every month, with dead domains dropping out and newly discovered ones coming in, and detection widens at the same time: the total number of domains seen carrying the Siteimprove signal moved from 8,964 to 13,772 across the same three months, faster than the active line. Read the three points as three sightings of a population we can see progressively more of, not as a trend in sales. One caution belongs here more than on most profiles. This is a page-level tag, so a domain enters and leaves this series on whether the script executed on the page we fetched that month, which is a different question from whether the account is live. The August figure, 12,493, is the one quoted at the top of this page.

Which Countries Use Siteimprove the Most?

Which countries use Siteimprove the most? The United States holds 4,132 of the 6,459 companies we could place, 63.96%, ahead of the Netherlands on 407 (6.30%), Canada on 389 (6.02%) and Norway on 298 (4.61%). The United Kingdom is fifth at 240 (3.72%), then Australia 207 (3.20%), Denmark 192 (2.97%), Sweden 102 (1.58%), Switzerland 72 (1.11%), Germany 55 (0.85%), Iceland 47 (0.73%), Finland 41 (0.63%), Italy 39 (0.60%), New Zealand 30 (0.46%) and Spain 27 (0.42%). Two readings sit in that table. The first is the founding country. Siteimprove started in Copenhagen, and the five Nordic countries together are 680 companies, 10.53% of the 6,459, more than double the United Kingdom on its own. Iceland contributes 47 companies from a population near 400,000, the highest per-capita reading of the fifteen countries shown. The second is Germany at 55 companies, 0.85%, behind Switzerland on 72 and barely above Iceland. A vendor with a Nordic base and a Dutch second place has thin coverage in the largest German-speaking market, and at this sample size that is a real gap rather than a rounding effect. Country here is the headquarters on the company record, not where the web team sits.

Siteimprove Market Share Among Web Analytics

What is Siteimprove's market share? Siteimprove holds 0.07% of Web Analytics and ranks 32nd of 100 in that category, on 12,493 domains. The rows above it are general web analytics: Google Analytics on 10,942,935 domains and 64.26%, Cloudflare Browser Insights on 1,916,483 (11.25%), Site Kit on 616,569 (3.62%), WordPress.com Stats on 447,144 (2.63%) and Snowplow Analytics on 380,244 (2.23%). Before reading anything into 0.07%, look at what is being compared. Siteimprove sells accessibility auditing, content quality assurance and policy monitoring; the analytics module is attached to that rather than being the thing a customer signs for. A buyer choosing Siteimprove is not choosing between it and Google Analytics, and most of these domains run both. The share counts domains carrying a detectable script inside one taxonomy bucket, and it is not a measure of spend, of pages audited, or of accessibility work done.

Siteimprove Customers by Company Size & Age

What size companies use Siteimprove? The distribution leans small and the named table does not, and the two are easier to read together than apart. 1,604 of the 6,261 companies with a size band, 25.62%, employ 1 to 10 people, and 2,662, 42.52%, employ 50 or fewer. The middle holds 51-200 at 1,018 (16.26%) and 201-500 at 783 (12.51%). Above 1,000 employees there are 1,241 companies, 19.82%, split across 1,001-5,000 (808, 12.91%), 5,001-10,000 (186, 2.97%) and 10,001+ (247, 3.95%). Now set that against the named list, where all 50 organisations sit in the 5,001-10,000 or 10,001+ bands. That list is ordered by LinkedIn following, which selects for federal agencies, state governments and large universities, so it shows the top of the base rather than its centre. The small end is not a free tier and it is not noise: small municipalities, community colleges, clinics, libraries and non-profits fall under the same accessibility rules as the large bodies and buy the same kind of monitoring on a smaller estate. Both ends of this curve are created by the same regulation.

What Industries Use Siteimprove the Most?

Government Administration leads at 14.79% of the 5,874 companies with a recorded industry, 869 companies, with Higher Education second at 726, 12.36%, and Hospitals and Health Care third at 430, 7.32%. Grouping the labels that describe the same buyer makes the shape obvious. Government Administration, Higher Education, Hospitals and Health Care, Primary and Secondary Education (126, 2.14%), Non-profit Organizations (124, 2.11%) and Research Services (105, 1.79%) come to 2,380 companies, 40.52% of the 5,874. That is the accessibility-mandate cohort. Section 508 of the US Rehabilitation Act, the EU Web Accessibility Directive and equivalent national rules apply to exactly these bodies, and they arrive as procurement conditions and audit obligations rather than as advice. Regulated finance is the second block: Banking 246 (4.19%), Financial Services 223 (3.80%) and Insurance 162 (2.76%) add 631 companies, 10.74%, reached by the same accessibility expectations through consumer protection instead of public procurement. Hospitality (144, 2.45%), Medical Practices (141, 2.40%) and Law Practice (132, 2.25%) complete the ten labels shown.

Public bodies using Siteimprove are the block that defines this page: 2,380 of the 5,874 companies with a recorded industry, 40.52%. The named table shows what that looks like at the top of the list. Federal agencies appear on their own properties, www.accesstocare.va.gov, www.taxpayeradvocate.irs.gov, www.dhs.gov, www.fema.gov, www.justice.gov and www.fns.usda.gov; state, provincial and city government on mn.gov, www.gov.ca.gov, www.alberta.ca and activiteiten.amsterdam.nl; universities on global.iu.edu, osu.edu, howdy.tamu.edu, www.crk.umn.edu, pe.gatech.edu and www.manchester.ac.uk. Higher Education at 726 companies, 12.36%, understates the work behind it, because one university is dozens of faculty, campus, library and admissions sites and each is a separate property that has to pass the same audit. Hospitals and Health Care at 430, 7.32%, brings MD Anderson Cancer Center, Baptist Health, Piedmont Healthcare and UT Southwestern Medical Center, where the obligation attaches to patient-facing information. Banks and insurers using Siteimprove come to 631 companies, 10.74%, with U.S. Bank, JPMorgan Chase, First Citizens, Chubb and NN Group named below. Two record caveats before reading any row too closely. Industry sits on the company record rather than on the site, so Xerox is filed under Business Consulting and Services and King's College London under Research Services rather than Higher Education. And a company type can disagree with an industry: MD Anderson Cancer Center carries an Educational company type alongside a Hospitals and Health Care industry, which is correct on both counts and confusing on one.

Siteimprove Alternatives & Competitors

This table lists the five largest technologies in the same taxonomy bucket, not the five products a Siteimprove buyer shortlists. Google Analytics on 10,942,935 domains and 64.26%, Cloudflare Browser Insights on 1,916,483 (11.25%), Site Kit on 616,569 (3.62%), WordPress.com Stats on 447,144 (2.63%) and Snowplow Analytics on 380,244 (2.23%) are general web analytics, and a Siteimprove customer usually runs one of them alongside Siteimprove rather than instead of it. The products Siteimprove actually displaces sit in our accessibility tools category, where Siteimprove does not appear at all. That is a filing decision on our side and it is better stated than hidden: we file this technology under Web Analytics because the signal it leaves is an analytics script, while the product is sold as accessibility auditing, content quality assurance and policy monitoring. Read the rank of 32 of 100 as a position in a taxonomy, not as a competitive set.

There is no switching table on this page, and that is a decision rather than a gap. We ran the destination query across all 146 other technologies in Web Analytics and Accessibility Tools, and nothing cleared its own base rate. Google Analytics sits on 55.2% of the 1,724 dropped domains we can read a stack for against 75.71% of the 14,237 live ones; Adobe Analytics 3.95% against 3.99%; Matomo 1.82% against 3.16%; UserWay 1.32% against 2.19%; Piwik PRO 0.71% against 1.12%. Every candidate destination is less common on the domains that lost Siteimprove than on the domains that kept it, which is the opposite of what a migration looks like. Domains that stopped showing Siteimprove did not move to a substitute. They stopped showing Siteimprove, which is the consent-gating finding arriving from a second direction. We publish nothing here rather than dress up noise as a trend.

Technology	Domains	Market Share
Google Analytics	10,942,935	64.26%
Cloudflare Browser Insights	1,916,483	11.25%
Site Kit	616,569	3.62%
WordPress.com Stats	447,144	2.63%
Snowplow Analytics	380,244	2.23%

Tech Stack of Siteimprove-Powered Websites

Every percentage in this table divides by the 14,238 domains our live crawl currently answers for Siteimprove, a different base from the 12,493 in the August rollup at the top of the page. No row here is a share of the headline count.

Start with tag management. Google Tag Manager is on 11,487 of the 14,238 live domains, 80.68%, with Adobe Experience Platform Launch adding 828 (5.82%), Adobe DTM 734 (5.16%) and Tealium 510 (3.58%). Siteimprove is almost always injected through a container rather than hard-coded into a template, and that single fact drives the churn reading on this page.

The content management group inverts the order we see across the rest of our records. Drupal at 2,887 (20.28%) plus Drupal Multisite at 904 (6.35%) reaches 3,791 domains, 26.63%, against WordPress at 2,396, 16.83%. Drupal is the CMS of US federal agencies and university web estates, and CivicPlus at 220 (1.55%) is a municipal government CMS with little reason to exist outside that buyer. Adobe Experience Manager at 796 (5.59%), Sitecore at 595 (4.18%), Optimizely Content Management at 474 (3.33%) and TYPO3 CMS at 258 (1.81%) fill in the enterprise and European public-sector tiers. This block reaches the same conclusion as the industry table through a signal that has nothing to do with company records, which is the useful kind of corroboration: two measurements that could disagree and do not.

Consent and privacy is the group to read next to the churn number: OneTrust 1,622 (11.39%), Cookie Control 528 (3.71%), Cookiebot 427 (3.00%), CookieYes 359 (2.52%), Osano 344 (2.42%), Cookie Information 223 (1.57%) and Transcend 206 (1.45%). Those rows count consent platforms on live domains, 31.71% of 14,237 in total. On the domains that stopped showing Siteimprove the same class of tool is on 73.14% of 1,724.

The accessibility group is interesting because it is small. ReadSpeaker 341 (2.40%), UserWay 312 (2.19%), AudioEye 240 (1.69%), AccessiBe 111 (0.78%), Texthelp 101 (0.71%), Silktide 79 (0.55%) and Allyant 24 (0.17%) sum to 1,208 of the 14,238 live domains, about 8.5%. Accessibility overlay widgets and Siteimprove's audit-and-monitor approach look like alternatives rather than companions: a site that has bought an overlay has usually not also bought an audit programme, and the reverse holds too. Silktide at 0.55% and Monsido at 1.66% of the 14,238 are the closest direct competitors that appear in this table at all, which says more about how little of this market leaves a client-side trace than about either vendor.
