Companies Using Facebook

Search for companies that use Facebook and you mostly find lists of brands with a Page. That isn't much of a signal, since nearly every consumer brand has one. The record this page counts is narrower and, for a marketer, more useful: a business that verified its domain with Meta. To do that by DNS, an admin publishes a TXT record, facebook-domain-verification= plus a code, and Meta's developer guide tells them to leave it in place because Meta may check it again. Our October 2026 crawl finds that record on 590,855 domains. We matched 346,753 of the 591,375 in our clean live set to a company, a 58.64% match rate.

What the record proves

It proves someone with access to the domain's DNS set up a Meta business account and claimed the domain. Meta's help page on domain verification gives the reasons to bother: to control who can edit links to its domain in ads and organic posts, to sell through Facebook commerce surfaces, to join the news Page index, and to finish business verification when its email domain or phone number won't do. Each of those is an advertiser's or publisher's job, and none puts anything on the website, which is why this page and our Facebook Pixel page count different things.

It's also a floor. Meta accepts two other methods, an HTML file in the site's root and a meta tag on the home page, and neither shows up in DNS. The match rate, 58.64%, is low next to the 84.84% (7,645 of 9,011) on our Amazon Business page, measured the same way, most likely because a one-person shop with an ad account often has no LinkedIn company page to match.

Sales signal: read each row as "this business has run, or set up to run, Meta campaigns for its own domain." For ad tech, creative tools and agency services that's a stronger signal than a Page count, and a weaker one than spend data, which a DNS record can't give you.

Growth trajectory

The chart reads 473,105 domains in June, 564,648 in July, 569,356 in August, 584,823 in September and 590,855 in October. Most of the gain, 91,543 domains, arrives between June and July, and the line has added 26,207 since. I wouldn't read that June step as a wave of new advertisers. The set of domains we crawl turns over every month, with dead domains dropping out and new ones added, and our detection widens over time, so a count like this jumps when our coverage does.

Few domains leave. 10,022 have lost the record since we began tracking it in March 2026, 1.7% of today's count, and 830 of them still carried it on another hostname when I checked on 11 October. Meta asks businesses to keep the record, so a company that stops advertising has little reason to delete it. Low churn here describes the record, not how loyal advertisers are.

"A Like button tells you a website wanted social proof. A verified domain tells you a business opened Meta's ad tools and claimed its own URL. If you sell to marketing teams, the second fact is the one worth building a list on." - Elif Arslan, CMO and Co-founder at TechnologyChecker.io

Sales signal: treat the list as a stable universe, not a timing trigger. The record won't tell you when a business started or stopped advertising, but it does tell you that someone there owns the Meta relationship.

Who the customers are

Mostly small businesses. 54.56% of matched companies with a known headcount have ten or fewer employees, 25.75% have 11 to 50, and only 2.79% (9,233 of 330,860) employ more than 1,000. They're young too: 44.48% of those with a known founding year started in the 2010s and 18.77% in the 2020s, so 63.25% date from 2010 or later. Picture a fitness studio, an estate agent or an online shop that buys its own ads. There's no entry fee to stop them: Meta says Meta Business Suite is free to use, and advertisers set their own budgets.

The big names are real. Accenture, Deloitte, McDonald's, IBM, Siemens, Bank of America, Starbucks, Apple and Nike all carry the record, and I checked every one of the 50 companies on this page in DNS. At that size the record says a marketing team verified the main domain. It says nothing about budget, and a group with many brands may verify each one in a different account.

Sales signal: for most of this list, the person who verified the domain is the owner or a one-person marketing team. Pitch the work they do by hand, such as creative, reporting or product feeds, and price for a small business. The enterprise rows need a separate motion that starts with the brand team.

Industries and countries

Retail leads at 6.99%, then advertising services (4.73%), IT services (3.8%), software development (3.35%) and internet companies (3.32%). The top ten add up to 34.74%, so no vertical owns this list. For a seller, the consumer businesses matter most, such as apparel (2.86%), real estate (2.78%) and wellness and fitness (2.66%), and so do agencies. Agencies verify their own domains, and Meta's guide asks them to have each client verify its domain in the client's own account.

Geography is broad. The United States has 97,609 matched companies, 28.15% of the 346,753, then Brazil (27,088), the United Kingdom (22,795), Germany (15,536), Australia (14,792) and Canada (13,103). India (12,109) and the Netherlands (10,994) follow. Brazil in second place is the figure I'd act on, because it ranks ahead of every European market.

Sales signal: a Portuguese-language campaign aimed at Brazilian retailers reaches more matched companies (27,088) than Germany (15,536) and France (10,071) combined. The advertising services rows are the other shortcut: an agency that runs Meta campaigns for clients can carry your product into many accounts at once.

Pixel, no Pixel and the rest of the stack

Percentages here are of the 591,374 live domains in our clean set. The Facebook Pixel runs on 49.32%. So about half the businesses that verified a domain also fire Meta's browser script on the pages we crawl, and about half don't. Some of that second half send events server-side, which a crawler can't see; others verified for link control or commerce and never set up tracking. For scale, our Facebook Pixel profile counts 3,428,681 domains, so most sites that run the Pixel haven't published this record.

Second ad channels are thin. The TikTok Pixel is on 8.29%, Google Ads conversion tracking on 7.36%, the LinkedIn Insight Tag on 5.34%, Pinterest's conversion tag on 1.96% and the Snapchat Pixel on 1.23%. The storefront side is heavier: Shopify builds 22.36% of these sites and WooCommerce 6.72%, WordPress runs 29.39% and Elementor 11.71%, and Klaviyo (9.59%) is ahead of Mailchimp (6.13%) for email.

"Half of the businesses that verified a domain with Meta don't run the Pixel on the pages we crawl. Some track server-side and some don't track at all, and either way that half is the first list I'd hand a measurement vendor." - Elif Arslan, CMO and Co-founder at TechnologyChecker.io

Sales signal: the verified-without-Pixel half is the opening for conversion tracking and server-side event tools. For a second ad channel the gap is wider still: fewer than one in ten of these domains runs the TikTok Pixel.

Why there's no market share

Our Social Media & Content Curation table is built from share buttons and feed widgets such as AddToAny and ShareThis. A Meta business account would top it, and that position would tell you nothing, so we publish neither a share nor a competitor table. The ad-channel figures above are the fairer comparison.

Key takeaways

1. 590,855 domains carry a Meta domain-verification record in October 2026, a floor on business accounts, with 346,753 matched to a company.

2. It's a small-business list: 54.56% of matched companies with a known headcount have ten or fewer staff, and 63.25% were founded in 2010 or later.

3. The United States leads with 97,609 matched companies, and Brazil (27,088) is second, ahead of every European country.

4. The Facebook Pixel runs on 49.32% of these domains, so the record and the Pixel measure different things.

5. Exits are low, 10,022 since March, because Meta asks businesses to keep the record.

How to use this list

Start with the size band you sell to, then split by whether the domain runs the Pixel. A first line that works for a creative or reporting tool: "You verified your domain with Meta, so you run your own campaigns; here's how other retailers your size cut the hours they spend on ad creative."
