Companies Using WP Rocket

I expected this refresh to move one number. Our October 2026 crawl finds WP Rocket on 681,717 live domains once stale, for-sale and gambling domains are set aside, 451,591 of them matched to a company. That's down from the 733,891 this page showed from August, and the cleaning explains only part of the gap. The rest is movement in the crawl, and I wanted to know whether the sites leaving were real before writing a word about it.

Fewer domains, and the losses are real

In the 90 days to 21 October, 125,661 domains dropped WP Rocket and 91,251 were seen with it for the first time. Totals in our crawl aren't a fixed panel: the domains we crawl turn over every month and our detection widens, so first sightings include sites that are new to us. Drops are firmer, because a domain only counts as one after a successful rescan finds none of WP Rocket's code. My first suspicion was the rule. A plugin that renames its markers makes upgraders look like leavers. WP Rocket's changelog from 3.22 to 3.23.5.1, the releases before our October crawl, removes no front-end marker, and the generator tag, which has listed the active features since late 2024, makes it easier to see, not harder. So I reopened 80 of the leavers that still run WordPress. 71 answered, and 63 showed no WP Rocket code at all. Seven still did, two of them on another domain they now redirect to.

The rate is what stands out. 14.86% of the domains live with WP Rocket now or dropped in that window left within 90 days. Rank Math's rate was 7.51%, Contact Form 7's 6.87% and Autoptimize's 8.76%. LiteSpeed Cache's was 13.83%. Of the paid tools, NitroPack's rate (19.78%) was higher still.

"One in seven WP Rocket domains dropped it in 90 days, about twice the rate of Rank Math or Contact Form 7, and when we opened those sites, nearly nine in ten had no WP Rocket left. These are real departures." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: WP Rocket installs turn over faster than the other plugins we compared. A list built from them needs a monthly refresh, and a site that dropped it in the last 90 days is worth a call while it decides what, if anything, replaces it.

Who buys it

59.52% of matched companies have 1 to 10 staff and 26.34% have 11 to 50. 37.06% were founded in the 2010s, but 27.9% before 2000. Put together, the core buyer is an established small business with a WordPress site and, usually, nobody whose job is site speed. The enterprise names sit on narrow sites. 25 of the 49 companies on our list run WP Rocket on a subdomain: Concentrix on its jobs site, STMicroelectronics on its blog, NYU Langone Health, Northside Hospital and Baylor College of Medicine on their donation sites. Engie, Bouygues, GlobalFoundries and REWE Group run it on their main domains.

Sales signal: at a large company, the WP Rocket owner is usually the team behind one microsite, often careers, giving or a blog. Sell to that team, not to central IT.

Industry and country

No industry passes 6%. Construction leads at 5.62%, agencies (Advertising Services) follow at 3.33%, and the two health labels together make 5.26%. Geography is the sharper signal. The United States has 123,741 matched companies, but the ten European countries in the top 15 hold 179,294 between them, led by France (36,267) and Germany (35,525). WP Media is a French company registered in Lyon, and the French count sits only 742 above Germany's.

Sales signal: for anything sold alongside WP Rocket, Europe is not a side market. French, German, British and Dutch sites together outnumber the US base, so localised outreach pays here.

Where the leavers go

Only one switching pair passes our tests: 33 domains moved to FastPixel, 6 the other way. That's too small to call a trend. The overlaps are much larger. 33,921 domains run WP Rocket and LiteSpeed Cache today, and 63,333 have run both at some point since March, so that pair fails our switching test: more than half of those sites never chose between them. Among the 71 leavers I reopened, 12 now show LiteSpeed Cache, and 25 of the 63 with no WP Rocket left show some other speed plugin. The rest run nothing we could see.

"Most sites that drop WP Rocket don't move to a paid rival. They fall back on whatever their host gives them, or on nothing." - Mehmet Suleyman, CEO & Co-founder at TechnologyChecker.io

Sales signal: hosts are the real competitor. A site on a LiteSpeed host has a free cache already, so the renewal case has to rest on what WP Rocket adds on top.

What owners switch on

Since late 2024 WP Rocket writes the features it applies into its generator tag, so I counted them. On the 473 sampled homepages that carry it, critical-image optimisation is on 84.36%, link preloading on 75.48%, CSS minification on 71.67% and image lazy-loading on 58.99%. Remove Unused CSS is on only 23.26%. 321 of the 473 ran a 3.23 release, the current line when we sampled in October. The stack around it is SEO-heavy: Yoast SEO on 54.77% of clean domains and Rank Math on 21.72%, Elementor on 36.82%, Cloudflare on 35.9%, HubSpot on only 3.75%.

Sales signal: an owner who runs WP Rocket plus Yoast or Rank Math has paid for speed and set up search. That pair marks a site that already treats organic traffic as revenue.

Reviews against the crawl

In the G2 review summary on this page, the most-mentioned complaint is the lack of a free version. The crawl agrees in an odd way: WP Media's own free LazyLoad plugin sets one of the same JavaScript variables, and in a sample of 724 live domains that answered, 24 (3.31%) ran only the free plugin. Reviewers also mention CSS conflicts with themes and page builders, which may be why Remove Unused CSS is switched on at only 23.26% of the sites that list their features.

Sales signal: price is the objection reviewers raise most. Lead with what the owner already uses, not with a feature they've left switched off.

Key takeaways

1. 681,717 live domains, 2nd of 12 in Caching with 24.11%, and 18.8 times NitroPack's count.

2. It is shrinking in our crawl: 125,661 domains dropped it in 90 days, a 14.86% rate, and 63 of 71 reopened leavers had no WP Rocket left.

3. The buyer is small: 85.86% of matched companies have 50 staff or fewer.

4. Europe outweighs the US: 179,294 matched companies in ten European countries against 123,741.

5. Leavers mostly fall back on their host or nothing; the only passing switch is 33 domains to FastPixel.

Sales applications

Outreach template: "Your site runs WP Rocket alongside [Yoast SEO / Rank Math]. Across the 451,591 WP Rocket domains we can match to a company, most are small teams that already invest in speed and search. If [your product] fits that setup, a short call could be worth it."

Targeting strategy: filter for 11-200 employee companies in construction, agencies and health care in the US, France, Germany, the UK and the Netherlands. They have budget, a WordPress site and usually no in-house developer.

Competitive angle: for performance vendors, the 125,661 domains that dropped WP Rocket in 90 days are the open market. Most of them run no visible replacement.
