Companies Using Google AdSense

Our August 2026 crawl detects 677,940 domains running Google AdSense, which makes it the second-largest technology in our Ad Networks category on a 14.68% share, #2 of 282. I worked from the 181,943 companies we could match to a detected domain, and the industry breakdown is the most interesting thing on this page. AdSense is the publisher-facing half of Google Ads, and its footprint says something specific about who still monetises a web audience with display.

The publisher signature

Most technologies we profile skew toward one vertical or spread evenly across business software buyers. AdSense does neither. Its top ten industries are led by Technology, Information and Internet (4.55%), IT Services and IT Consulting (4.22%) and Advertising Services (4.12%), which is unremarkable. What is remarkable is that Online Audio and Video Media (2.85%, 4,503 companies), Book and Periodical Publishing (2.73%, 4,305) and Media Production (2.35%, 3,712) all appear in the same ten. Three media and publishing categories in a single top ten is a distribution nothing else in this category produces. Together those three account for 12,520 companies, or 7.93% of the matched base.

The flat tail says the same thing from the other direction. No industry clears 5%, and the gap between first place and tenth is barely two points. AdSense is not concentrated anywhere because it is horizontal by design: any site with pages and readers can run it, and the sites that do are mostly small.

Sales Signal: The 12,520 matched companies in video media, periodical publishing and media production are the clearest prospect list on this page. They monetise audience for a living, which means ad yield is a revenue line rather than a side project, and they are the segment most exposed to any change in display CPMs.

"Three of the ten biggest industries running AdSense are media and publishing. Nothing else in the category looks like that. AdSense is not an ad network with publishers attached, it is a publisher network." - Mehmet Suleyman, CEO at TechnologyChecker.io

What the number counts

AdSense is identified from the code a page serves: five JavaScript globals including adsbygoogle, google_ad_ and Goog_AdSense_, the AMP ad element publishers use on accelerated pages, and script sources including googlesyndication.com and doubleclick.net. Some of those script hosts are shared with other Google ad products, so 677,940 is best read as the number of domains carrying Google ad-serving code of the AdSense family rather than the number of signed AdSense accounts. It is also a count of domains. A publisher operating twenty sites appears twenty times, so this figure sits above any account count. At roughly 2.3% of all domains we detect technologies on, AdSense is one of the most widely deployed tags on the consumer web.

What AdSense pays

The revenue split has held stable for well over a decade. Publishers earn 68% of revenue when ads on their site are bought through Google Ads, and 80% after the advertiser-side fee when third-party demand bids in (AdSense Help: revenue share). The 68% figure has been the public default since Google disclosed it in 2010 (AdSense blog, May 2010), and the November 2023 restructure made the arithmetic cleaner without changing what most publishers see (Google Blog, November 2023). The payment threshold is still $100, which keeps the smallest publishers waiting months for a first payout (AdSense Help: payment thresholds).

Size and age profile

This is a small-publisher product and the size data does not equivocate. 72.6% of matched companies have 1-10 employees and 18.4% have 11-50, so 91% sit under fifty people. Everything from 201 employees upward comes to 3.61%, and the 10,001+ bracket is 0.25%, or 421 companies. Those large names are real, though: United Airlines, Intuit, Hertz, Veolia, Safeway, Paramount Skydance and Televisa all serve the code somewhere. In almost every case it sits on a newsroom, an investor page or a microsite rather than the main commercial domain.

By founding decade, 47.96% started in the 2010s and 23.56% in the 2020s, with 15.76% from the 2000s. Nearly half the base was founded in the decade when content marketing and independent blogging peaked, which is consistent with what the industry mix shows.

"Ninety-one per cent of the AdSense sites we can match to a company have fewer than fifty employees. The real market for this product is the individual publisher, and it always has been." - Mehmet Suleyman, CEO at TechnologyChecker.io

Geography

The United States leads with 40,181 matched companies, but India ranks second on 17,717, ahead of Brazil (12,105), the United Kingdom (10,289), France (8,749) and Germany (7,407). Second place for India is unusual. Most advertising and marketing products we profile put three or four European markets between the United States and the first Asian country. Spain (5,504), Canada (4,764), Italy (4,498) and Australia (3,657) fill out the top ten, with Turkey (2,772), Indonesia (2,498) and Mexico (2,219) close behind.

Sales Signal: India's 17,717 matched publishers and Brazil's 12,105 are large, English-and-Portuguese-language audiences with almost no premium ad management competition. Yield optimisation offers priced for those markets face a far emptier field than the same offer in the United States.

Pressure on publishers in 2026

Between 13 and 15 January 2026, AdSense publishers reported revenue drops of 50-90% tied to Ad Exchange match rate failures (Search Engine Land), and Google acknowledged a systemic delivery issue. That landed on top of a harder structural problem. Press Gazette and Chartbeat data show global Google search traffic to publishers fell 33% in the year to November 2025, with the United States down 38% (Press Gazette, January 2026). When sessions fall and CPMs compress at once, the arithmetic stops working for marginal sites. 63,369 domains have dropped the tag since this profile began tracking in March 2026, which against 677,940 active domains is a churn rate under 10% and low for a product with no contract.

Sales Signal: Those 63,369 lapsed domains already know how display monetisation works and already have ad-ready content. They are a warmer list than any cold publisher segment, and the January 2026 event gives an outreach hook that needs no explaining.

Technology ecosystem

AdSense publishers run a recognisable and slightly dated stack. WordPress (41.38%) dominates the CMS slot, with Elementor on 10.17%. Google Analytics (58.88%) is near-universal for measurement. The front end is jQuery (57.68%), jQuery Migrate (34.87%), core-js (25.99%) and jQuery UI (15.72%), which is the profile of sites built on themes rather than component frameworks. Cloudflare (24.84%) is the leading CDN.

The ad-side overlaps matter most. DoubleClick Floodlight appears on 9.14% of AdSense sites, Google Publisher Tag on 5.07%, and the Prebid header-bidding library on only 2.78%. Header bidding is the standard way larger publishers lift CPMs, and fewer than three AdSense sites in a hundred run it. The typical AdSense site is a single-tag site.

Sales Signal: The 97% of AdSense sites with no Prebid detection are the addressable market for any managed ad service. They have inventory and no bidding infrastructure, and the WordPress concentration means one plugin-shaped integration reaches most of them.

Key takeaways

1. 677,940 domains, 14.68% of the Ad Networks category, #2 of 282. The leader, DoubleClick Floodlight, is an advertiser-side conversion tag, so AdSense is the largest publisher-facing network in the category.

2. Three of the ten largest industries are media and publishing. No other ad tag in our data shows that shape.

3. 91% of matched companies have fewer than fifty employees, and only 0.25% have more than 10,000.

4. India ranks second by country with 17,717 matched companies, ahead of every European market.

5. Only 2.78% run Prebid. The overwhelming majority of AdSense inventory is sold through a single tag with no competing demand.

Sales applications

Outreach template: "Hi [Name], I noticed [Company] runs Google AdSense on WordPress without a header-bidding layer. Only 2.78% of AdSense sites run Prebid, which means most are taking the first bid they are offered. We have helped similar [industry] publishers add competing demand without changing their ad layout. Worth twenty minutes?"

Targeting strategy: filter for the 12,520 publishers in Online Audio and Video Media, Book and Periodical Publishing and Media Production, in the United States, India or Brazil, with 11-200 employees. They have enough traffic for optimisation to pay for itself and rarely have a dedicated ad ops team.

Competitive angle: the 63,369 domains that dropped AdSense since March 2026 are lapsed publishers with content still live. Faster payouts and a higher effective RPM are the two arguments that move them.
