Companies Using SiteGround

Our live crawl finds SiteGround serving DNS for 123,341 domains, of which 103,654 resolve to an identifiable organisation. 72.32% employ ten people or fewer. Construction is the largest industry at 9.08%, and named users include Hinduja Global Solutions, eClerx, Vistaprint, Old Dominion University, Cal Poly Pomona, Flowers Foods and LA Metro.

We detect 123,341 active domains on SiteGround as of our August 2026 rollup. Counts are domains rather than accounts, and one hosting account commonly serves several domains, so the account number is lower than this. Unlike most technologies we measure, the figure is not depressed by suppression: the signal is a nameserver record, which a live site cannot remove.

SiteGround holds 1.27% of Web Hosting and ranks 14th of 50, behind GoDaddy at 4,378,121 domains, Hostinger at 1,192,207, IONOS at 637,254, OVHcloud at 426,618 and WP Engine at 348,566. The category mixes registrars with hosts, so the leaders' figures include domains that are registered and parked rather than served.

Among hosts we profile, the closest by product are WP Engine (348,566 domains), Kinsta (91,514) and Cloudways (65,170), all managed WordPress specialists. Hostinger (1,192,207) and IONOS (637,254) compete on price at the shared-hosting end. We publish no switching data between them, because every pair we tested still runs both signals on most shared domains.

The United States leads with 41,561 matched companies (44.24%), followed by the United Kingdom at 13,700 (14.58%), Australia at 7,240 (7.71%), Italy at 6,510 (6.93%), Canada at 5,531 (5.89%) and Spain at 4,168 (4.44%).

72.32% of matched SiteGround companies employ 1 to 10 people and 19.68% employ 11 to 50, so 92.00% are under fifty staff. Companies over 200 employees are 2.32% of the matched base and usually appear on a single project or country site rather than across their estate.

42.02% of matched companies were founded in the 2010s, 20.35% in the 2020s and 18.03% in the 2000s. The base skews slightly older than the newer managed hosts, which is consistent with SiteGround having operated since 2004.

A company of 1 to 10 employees, founded in the 2010s, based in the US, UK, Australia, Italy or Spain, in construction, advertising, consulting or real estate, running a WordPress brochure site built by a small agency.

From DNS. SiteGround's authoritative nameservers follow a fixed pattern under sgvps.net and its SOA record names siteground.net, and we also match a set of host-header fingerprints. This matters for how much the number is worth: script tags can be inlined, headers stripped by a proxy and generator comments deleted from a theme, but a domain that removes its nameservers stops resolving. Compare our Jekyll profile, published the same day, where the only signal is a meta tag any theme can delete.

Largely. WordPress appears on 72.64% of SiteGround domains and Nginx on 76.40%. That is a lower WordPress concentration than the premium managed specialists show, which fits SiteGround's position as a shared host that is good at WordPress rather than one that only does WordPress.

Our data cannot say, and the reason is instructive. 7,358 domains have been seen under both names and 5,846 still are, a 79.45% overlap. GoDaddy is a registrar as well as a host, so a domain bought at GoDaddy and served by SiteGround carries both signals at once, permanently. Reading that pair as movement would be wrong, so we publish no corridor for it.

Construction is 9.08% of SiteGround's matched base, the highest of any host we profile and 1.63 times the next. Grouped with advertising services (7.90%), business consulting (6.00%) and real estate (4.85%), 27.83% of the base is a local service business. The advertising row is probably the cause rather than a separate market: small agencies build these sites and place every client on the host they already use.
