Is Criteo's Self-Serve Ad Platform Open to All Advertisers in 2026?

No — Criteo's self-serve platform, Criteo GO, is not open to every advertiser worldwide in 2026. Criteo expanded GO to full self-service access on March 31, 2026, but that expansion covers small and mid-sized businesses in the United States and United Kingdom only; other markets are planned for later in 2026 without a disclosed timeline, according to Criteo's own press release.

What Actually Changed on March 31, 2026

• Full self-service replaced a more limited GO offering. Criteo's investor relations announcement describes the update as expanding GO "with full self-service access to its AI-powered performance platform," implying the earlier version of GO required more involvement from Criteo's own team.
• The self-serve tool covers multiple formats in one place. Advertisers can run display, video, native, and social campaigns inside a single GO campaign environment rather than managing each format through a separate workflow.
• Criteo brought in new leadership for the rollout. Courtney MacConnell, formerly head of Shopping at Google, was named Vice President of Commercialization for GO specifically to support the platform's global expansion.

Who's Actually Covered Right Now

• US and UK small and mid-sized businesses can access full self-service GO today.
• Growth-stage brands in those two markets are included in the same expanded access.
• Advertisers outside the US and UK, and larger enterprise accounts generally, still go through Criteo's traditional, sales-led onboarding path rather than self-service sign-up.

Why Criteo Is Rolling This Out in Stages

Criteo's core business has historically run on a quote-based, sales-assisted model, which is a meaningfully different go-to-market motion than a self-serve platform a business can sign up for directly. Opening GO fully in just two markets first lets Criteo validate the self-serve experience, support load, and billing mechanics before extending the same access globally — the same staged pattern most ad platforms use when moving from a sales-led model toward self-service, rather than opening every market at once. It also lets Criteo's existing account teams keep handling the larger retail-media relationships that still depend on custom deal terms, while the self-serve product absorbs the smaller accounts that a sales team can't service efficiently.

What This Means If You're Outside the US or UK

If your business is based outside the US or UK, or if you're a larger advertiser evaluating Criteo, expect a sales-led onboarding conversation rather than a self-serve sign-up flow for now. That doesn't mean Criteo's retail media inventory is unavailable to you — it means the specific self-service, sign-up-and-launch GO experience that smaller US and UK advertisers now have isn't yet extended to your market or account size.

Bottom Line

Check whether your business is a US or UK small-to-mid-sized or growth-stage advertiser before assuming you can self-serve on Criteo GO — if you're outside that scope, reach out to Criteo's sales team directly rather than searching for a self-serve sign-up page that doesn't yet apply to you, and watch for Criteo's own announcements on further market expansion later in 2026.
