OneTag for Retail Media Offsite
Introduction
What is OneTag?
The Criteo OneTag is a code snippet to embed in your website's source code or tag management system. It measures and analyzes user interactions on your site. It also loads asynchronously, ensuring no impact on site performance or customer experience.
Common parameters
There are some common parameters which are shared between all the tags:
| Event | key | example value | description |
|---|---|---|---|
setAccount | account | 12345 | Your Criteo Account or Partner ID, provided by your technical contact, to route data to Criteo servers. |
setRetailerVisitorId | ID | 0193553C0A39937F23FC | A unique, unauthenticated user ID valid for at least 30 days. Used to track visitor behavior across sessions. Typically retrieved via a first-party cookie. |
setCustomerId | ID | 1SDFJI435FH12HFK2 | A consistent, internal ID for logged-in users, linked to accounts, purchase history, or membership programs. |
setEmail | d9c37700(...)18be88 | User’s email address in SHA256 hash format. |
