Self-Optimizing Block is a multivariate testing add-on that randomly displays a block variant to visitors. You monitor the progress of the test. The variant that generates the most conversions is the one that appears most over time.

**Note**

[A/B testing](docId\:JzXNoptGf00jv_LEVC5ed) provides a more functionally rich way of gauging site visitor reactions to content versions.
:::

After you install the add-on, a self-optimizing block type is available when you create [Blocks](docId\:YWIfiRoLzuUzvmqvUX3Ol).

Create content for multivariate testing:

1. Select **New Block** in the editorial interface.
2. Select the **Self-Optimizing Block** type to create content for multivariate testing.
3. Select a goal page for conversion, such as a confirmation page after posting a form.
4. Add the block variants you want to include, preferably 2-4 variants with similar content.
5. Publish the self-optimizing block.
6. Drag the self-optimizing block you created to a landing page and publish it.

A self-optimizing block is indicated with a specific icon in edit view.

**Note**

You cannot track external links. For example, a conversion is not registered if the conversion page has a shortcut link to an external Web page.

## Analyze statistics

Statistics are counted only in live view and automatically show the most successful block over time. The **Self-Optimizing Block** renders the best performing block variant in edit view.

**Exposures** are the number of page views, and **Conversions** are the number of visitors reaching the goal page.
