Companies Using RankMath SEO

We detect RankMath SEO on 939,870 domains, including Veterans Affairs, Mousquetaires Group, Flex. A detection means the technology is present on that domain, which for large organisations is often a single storefront or subdomain rather than a company-wide deployment. Among domains we matched to a company with a resolved industry, the most common is Construction (4.96%).

We detect 939,870 domains running RankMath SEO across our monthly crawl of live business domains. Company data could be matched for 602,371 of them (64.1%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 81,304 domains carried a RankMath SEO detection previously and no longer do.

RankMath SEO holds 17.28% of the SEO Tools category, ranking #2. This is a share of the domains we detect running a platform in this category — not a share of all websites, and not a share of spending — so it is not directly comparable to figures published on other denominators.

The top alternatives to RankMath SEO include Yoast SEO (68.87% market share), All in One SEO Pack (11.16% market share), Ahrefs (0.94% market share), Baidu Push (0.42% market share) — measured as a share of the domains we detect running a platform in this category.

United States leads with 130,165 matched RankMath SEO domains, followed by Germany (46,166), United Kingdom (45,230), India (32,319), Spain (30,197). These are counts within the 602,371 domains we could match to a company record, not the full detected base.

The most common company size is 1-10 employees, representing 63.36% of the RankMath SEO domains we could match to a company record and size — a subset of 602,371 matched companies, not of all 939,870 detected domains. This is followed by 11-50 employees (24.33%) and 51-200 employees (8.17%).

Among the RankMath SEO domains we could match to a company with a known founding date, the largest group was founded in the 2010s (38.84%), followed by the 2020s (23.11%). That matched subset is drawn from 602,371 companies and is not representative of all 939,870 detected domains. This suggests RankMath SEO is most popular among relatively young companies.

The ideal RankMath SEO customer is: Company Size: 1-10 employees, Platform: WordPress, Location: US, Germany, or UK, Founded: 2010-2029, Page builder: Elementor — based on our analysis of 602,371 enriched companies at TechnologyChecker.io.

RankMath is a WordPress SEO plugin launched in 2018 by MyThemeShop. It handles schema markup, sitemaps, redirects, keyword tracking and social metadata, and its free tier covers much of what competitors reserve for paid plans. We detect it on 939,870 domains, making it the second-largest technology in our SEO Tools category at 17.28%.

Our September 2026 crawl detects RankMath on 1,013,698 live domains, with 939,870 in the August monthly rollup that market share is computed on. The detection matches an asset request from /wp-content/plugins/seo-by-rank-math/ or the plugin's schema script, so it only fires when a crawled page actually rendered RankMath's output.

Our data cannot judge quality, but it can measure what people do. 18,099 domains dropped Yoast SEO and now run RankMath, against 5,271 moving the other way — a 3.4:1 flow with a 19.6x base-rate lift, which is the strongest migration corridor we have measured on any technology. Yoast remains four times larger at 3,746,462 domains. The honest summary is that Yoast leads decisively on installed base while RankMath is the one taking accounts.

In practice, no. Both plugins write the title tag, canonical URL and schema graph, so running both produces duplicate and conflicting output that search engines have to reconcile. That exclusivity is why this category shows real migration data: 13,990 domains do currently register both, but that usually indicates a migration in progress rather than a deliberate pairing.

RankMath holds 17.28% of the SEO Tools category with 939,870 domains, ranking 2nd of 48 behind Yoast SEO (68.87%) and ahead of All in One SEO Pack (11.16%). Those three hold 97.31% of the category's 5.44 million domains between them; fourth place, Ahrefs, is a different kind of product at 0.94%.

Small organisations, mostly: 61.74% of matched companies have 1-10 employees and 24.33% have 11-50. The industry mix is almost flat — Construction leads at just 4.96% — because a WordPress plugin inherits WordPress's distribution rather than expressing a market of its own. Larger detected users include NASA, the US Department of Veterans Affairs, Turkish Airlines and Flex.

The United States leads at 29.0%, followed by Germany at 10.3%, the United Kingdom at 10.1%, India at 7.2%, Spain at 6.7% and the Netherlands at 5.8%. RankMath is the least US-concentrated of the three major WordPress SEO plugins — All in One SEO Pack reads 36.2% and Yoast 31.8%.

23.1% were founded in the 2020s and 38.8% in the 2010s, with 17.2% in the 2000s. That 2020s share is the highest of the three major SEO plugins — Yoast reads 16.7% and All in One SEO Pack 21.1% — which is consistent with RankMath winning newer sites as well as converting existing ones.

WordPress on 99.3% is definitional. The distinguishing companion is Elementor at 47.14%, fourteen points above Yoast's 33.22% — RankMath skews toward page-builder sites. Google Analytics reaches 63.45%, Google Tag Manager 61.44%, jQuery 88.56% and Cloudflare 35.28%.

Yes, and this is one of the few places in our data where that claim survives testing. 18,099 domains dropped Yoast SEO and now run RankMath, with 16,662 of those moves inside the last 90 days and 5,676 inside 30. RankMath appears on 0.36% of the domains that kept Yoast but 7.01% of those that left, a 19.6x lift, and the flow runs 3.4:1. A further 3,300 domains came from All in One SEO Pack at a 9.4x lift.
