To run A/B tests that test your current setup or existing recommendations against Optimizely recommendations, request additional A/B test information by adding the `abTestContent`Â property.
| Name | Description and usage |
| abTestContent | [Optional] [String] Activate A/B test output. - **summary** – Returns only A/B test name and the page visitor's group. - **full** – Returns all available information. If you specify the property name with an empty string, summary is used by default. |
To request full A/B test information, set the `abTestContent` attribute in the tracking request to full, as shown below.
This results in the following info section being returned in the response.

Note
Each product can have different A/B groups. So, do not assume that a visitor in group **A** for recommendations is also in group **A** for another Optimizely product, such as, Optimizely Promote.
