A/B testing is a powerful tool for businesses to optimize their marketing campaigns. By testing different versions of a campaign with a randomly split audience, businesses can determine which version is more effective at achieving their desired outcome, such as increased conversions or engagement. This data-driven approach enables businesses to make informed decisions about their campaigns, improve their return on investment, and grow. Whether it's testing different ad copy, visuals, or call-to-actions, A/B testing can help businesses fine-tune their marketing strategies and achieve greater success. With our predefined Dynamic Content (DC) templates, you can easily create your own control group dispatcher. In this use case, we will use the DC campaign to run the dispatcher. The ready-to-use Java Script in the template will update the page body with `data-test-snrs` attribute according to predefined user allocation. The attribute can be later found in the customer profile with value A or B. ## Prerequisites --- - [Implement a tracking code](/docs/settings/tool/tracking_codes) into your website. ## Create dynamic content --- The dispatcher will assign users to 2 groups in 2 areas: - The group will be assigned as an attribute in the customer profiles. The attribute is called `test-snrs` and takes the following values: - **A** - recommendation group (people in this group are able to see recommendations and personalized content), - **B** - control group (people in this group should not get any recommendations and personalized content). - It will add a `data-test-snrs` (=”A” or =”B”) attribute to the page body, which you must use in any later campaign settings. You can find out more about this in the [What's next](#whats-next) section. 1. Go to **Experience Hub > Dynamic content > Create new**. 2. Enter the name of the dynamic content. 3. Choose the **Insert Object** type. 4. As the Audience, leave **Everyone**. ### Define content 1. In the **Content** section, select **A/B tests**. 2. In the **Variations** section, click **Allocation**. 1. Switch off the **Set equal** toggle. 2. Set the **Profile allocation** to A-90% / B- 10%.

If you have more that one dispatcher configured in your business profile (ex. for different percentages of audience) remember that two dispatchers cannot render on the website at the same time. In such case you need to make a delay for one of them. 1 second should be enough.

Click **Activate**. ## What's next --- The [above DC campaign](#create-dynamic-content) gives the `data-test-snrs` (=”A” or =”B”) attribute to the page body. You can see the attributes in client profile in **Behavioral Data Hub > Profiles**. You can use this attribute in all sorts of analytics. In order to send any DC campaigns to a recommendation group (group A), selector `body[data-test-snrs="A"]` should be placed in the campaign **Content** section, before the place where you want to render your DC campaign.
