Lookalike segments

What Lookalike segments are?

Lookalike segments are a powerful tool within Meiro Business Explorer that allows you to create segments based on the attributes defined in Lookalike settings under the Administration tab. These segments are designed to closely resemble or "look like" existing segments, enabling you to expand your audience and target users with similar characteristics to those already in your base segment.

Create Lookalike Segments

Creating a lookalike segment from the Lookalike segment tab

1. Go to the Lookalike Segment tab and click the "Create Lookalike Segment" button.

2. In the window that appears, use the segment picker to choose the base segment you wish to use as a reference for your lookalike segment. You can select from custom or featured segments, provided you have access to view them.

Upon selecting your base segment, its size is fetched and pre-filled in the corresponding field, which cannot be modified. Once this size is loaded, the rest of the segment creation settings will become enabled.

3. To configure the size of your lookalike segment, you can start interacting with the slider.

Remember: you cannot create a lookalike segment with a size of 0. Furthermore, the size limit is 20% of the total CDP profile base. You can't create a lookalike segment larger than this limit by moving the slider or entering a bigger number in the lookalike segment size field.

4. Proceed with the "include base segment" checkbox. By default, it remains unchecked. Selecting this option indicates your preference to include profiles from the base segment into the newly created lookalike audience.

The "Include base segment" checkbox changes the slider's behavior. It ensures that the base segment size is considered and not excluded from the lookalike segment. This can be particularly useful when you want to include profiles with specific characteristics from your base segment in your lookalike audience.

5. Review your settings and ensure they align with your targeting goals and audience size. Click the "Create” button to create your new lookalike segment.

Creating a lookalike segment from custom/featured segment detail page

You also have the option to create a lookalike segment directly from the detail page of a custom or featured segment, provided the segment has defined conditions.

1. Navigate to the custom/featured segment detail page. Ensure that the selected segment has specific conditions defined. If there are no conditions in the segment description, the button for creating a lookalike segment will be disabled.

2. If the conditions are met, you can proceed by clicking the "Create Lookalike Segment" button located within the segment detail page.

3. A new window will appear, where you will need to follow a similar process outlined in the Lookalike Segment tab. It's important to note that the selected segment is already pre-filled and cannot be changed from this window.

4. Take a moment to review your settings. Once you are satisfied, click the "Create" button to generate your new lookalike segment. You will then be redirected to the detail page of this newly created lookalike segment on the Lookalike Segment tab.
