Companies Using Criteo

We detect Criteo on 110,313 domains, including Samsung, Walgreens, United Airlines. 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 Retail (7.68%).

We detect 110,313 domains running Criteo across our monthly crawl of live business domains. Company data could be matched for 41,844 of them (37.9%), and every company-size, industry and country breakdown on this page describes that matched subset rather than the full detected base. A further 76,144 domains carried a Criteo detection previously and no longer do.

Criteo holds 2.39% of the Ad Networks category, ranking #7. 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 Criteo include DoubleClick Floodlight (31.1% market share), Google AdSense (14.68% market share), Microsoft Advertising (7.45% market share), Pinterest Ads (6.85% market share) — measured as a share of the domains we detect running a platform in this category.

United States leads with 16,350 matched Criteo domains, followed by United Kingdom (3,011), India (2,323), Brazil (1,439), Canada (1,261). These are counts within the 41,844 domains we could match to a company record, not the full detected base.

The most common company size is 1-10 employees, representing 58.65% of the Criteo domains we could match to a company record and size — a subset of 41,844 matched companies, not of all 110,313 detected domains. This is followed by 11-50 employees (22.73%) and 51-200 employees (10.34%).

Among the Criteo domains we could match to a company with a known founding date, the largest group was founded in the 2010s (44.98%), followed by the 2000s (17.34%). That matched subset is drawn from 41,844 companies and is not representative of all 110,313 detected domains. This suggests Criteo is most popular among relatively young companies.

The ideal Criteo customer is: Company Size: 1-10 employees, Location: US, France, or Brazil, City: Paris, Sao Paulo, New York, London, Founded: 2010-2019, Company Age: ~10-15 years old — based on our analysis of 41,844 enriched companies at TechnologyChecker.io.

Criteo's platform uses commerce-focused AI trained on ~$1 trillion in annual ecommerce sales data. Advertisers install a tracking pixel, which collects browsing and purchase signals. Criteo's engine then matches this data across its ~740 million daily active users to serve personalized product ads across thousands of publisher sites. The company serves roughly 2 trillion ads per year, per its Q4 2025 investor fact sheet.

Criteo retargeting (now part of Criteo Commerce Growth) shows personalized display ads to people who previously visited your website but didn't complete a purchase. The platform dynamically generates ad creatives featuring the exact products each user viewed, along with complementary recommendations. Criteo's retargeting operates across thousands of publisher sites and apps without requiring advertisers to manage individual placements.

Retail is Criteo's largest detected vertical at 7.68% of the 41,844 domains we can match to a company, and named brands include Marriott, Samsung, IKEA and adidas. Our August 2026 crawl detects Criteo tags on 110,313 domains overall, though Criteo itself reports roughly 17,000 clients; the difference is that its tags also appear on publisher inventory it buys from, not only on advertisers.

AdSense monetises a publisher's inventory by filling it with Google's ad demand; Criteo primarily buys inventory on behalf of retailers to retarget shoppers, though it also works with publishers. They are complements more often than alternatives, and our data shows it: among domains that still run Criteo, 10.66% also run AdSense, while only 5.86% of those that dropped Criteo do. By footprint AdSense is far larger at 677,940 domains against Criteo's 110,313.

By detected footprint the Ad Networks category is led by DoubleClick Floodlight (1,436,200 domains), Google AdSense (677,940), Microsoft Advertising (344,173), Pinterest Ads (316,487) and Twitter Ads (297,888), with Criteo seventh at 110,313. Most of those are companions rather than rivals: Floodlight appears on 58.63% of live Criteo domains. Criteo's genuine commercial competitors are retail media networks and retargeting specialists, many of which run server-side and leave no comparable client-side trace.

No, Criteo isn't free. It operates on a cost-per-click (CPC) model where advertisers pay only when users click on their ads. There's no fixed monthly fee, but Criteo typically requires a minimum ad spend to start campaigns. The platform's self-serve option (Criteo Commerce Growth) has lower entry barriers than its managed service offerings, making it accessible to small and mid-size businesses.

Criteo's AI (called Commerce AI) processes shopping data from roughly 740 million daily active users and ~5 billion product SKUs. It uses predictive bidding to determine what to bid on each impression, product recommendations to select which items to show, and dynamic creative optimization to design the ad layout. Criteo employs ~1,200 R&D and product engineers (per its Q4 2025 fact sheet) and is now investing in agentic AI capabilities.

Retail leads at 7.68% of matched companies, followed by Technology and Internet (4.69%), IT Services (3.26%), Restaurants (3.13%) and Software Development (2.83%). The publisher cluster is worth separating: newspaper publishing (2.70%) and broadcast media (2.38%) reach 5.08% combined, and those domains typically carry Criteo to sell inventory rather than to advertise.

Our data shows 58.65% of matched Criteo domains belong to companies with 1-10 employees and 22.73% to those with 11-50. That said, a detected tag is not necessarily a client relationship, and the smallest domains are disproportionately publisher inventory rather than advertisers. Criteo's commercial model, with minimum spends and catalogue feed requirements, is aimed at merchants with meaningful product ranges.

It is built for it: Criteo describes itself as a commerce media company and retail is its largest detected vertical at 7.68%. The platform-level detail is telling. Among live Criteo domains, Magento appears on 4.68% against Shopify's 2.97%, and Adobe Experience Manager (15.81%) outranks WordPress (12.72%). That skew points to larger, established merchants with substantial catalogues rather than the small-store long tail.

Criteo Commerce Max is the demand-side platform for retail media, letting brands and agencies run campaigns across multiple retailer sites from one interface. It connects to Criteo's retail media network, which includes ~70% of top-30 US retailers and ~50% of top-30 EU retailers (per Criteo's Q4 2025 fact sheet). Commerce Max supports sponsored products, display, and onsite placements, and recently added Lidl and JB Hi-Fi to its retailer network.

Criteo GO is a self-serve performance advertising platform powered by Criteo's AI, designed for brands of any size. In March 2026, Criteo expanded GO with full self-service access to its AI-powered performance platform. GO lets advertisers launch cross-channel campaigns with simplified setup and automated optimization. Over 40% of Criteo's live clients now use more than one solution, and GO is the entry point for many SMB advertisers.

Criteo reported $1.945 billion in revenue for fiscal year 2025, roughly flat year over year. Gross profit grew 7% to $1.049 billion, and the company processed $4.3 billion in total media spend. Criteo trades on NASDAQ under the ticker CRTO and has no long-term debt, with $342 million in cash as of December 31, 2025 (per its Q4 2025 earnings release).
