## Integration flow

The integration timeline can vary depending on the resources available and the level of prioritization. Here is an overview of the integration flow and steps:

* **The preparation phase** follows the initial kick-off. That's a time dedicated to the creation and validation of the ad formats and mock-ups, as well as providing the integration documentation and setting up the product feed alongside its QA and ingestion. This is followed by the account setup.
* **The technical integration phase** has two parts:
  * the first part is dedicated to Ad requests development, testing and QA,
  * the second part focuses on Ad rendering and beaconing development, testing and QA.
* **The "Go live" phase** goes from Prod release, to Prod & Data QA, to the actual "go live", followed by algorithm optimization

## Timeline precisions

* Each step duration depends on the integrated scope and on retailer’s integration capacity and resources.
* QA duration depends on the scope and round(s) of feedback between Criteo and the Retailer.
* For example, an 8 to 10 weeks duration is standard for a scope of `Sponsored Products` in one environment (Web/Web mobile or Apps). Whereas, simultaneously integrating a scope of `Sponsored Products` & `Commerce display` formats in multiple environments and countries is estimated to take from 15 to 20 weeks.

## Onsite vs. Offsite

At Criteo, Retail Media solutions are split into two categories: **Onsite** and **Offsite**.

### Onsite

Onsite advertisements are displayed within a retailer's website or mobile app. Onsite ads use first party data to reach shoppers who visit, browse, or search on a specific retailer. There are two campaign types, which include Onsite Display and Sponsored products.

### Offsite

Offsite is a Retail Media solution used to target unique audiences using retailer first-party data to reach shoppers across the open internet.

<Note>
