Web banners: displaying and testing a web banner to a segmented audience

Prerequisites for web banners


To work with web banners, first, they need to be set by the Meiro team:

1. Meiro Events must be implemented.

2. Meiro Events API connection must be set in the Administration/ Settings tab.

3. Web banners tabs must be enabled by the administrator for your user role.

4. For embedded web banners it is required to place a DOM element with a unique ID in the HTML code of the website where the banner will be displayed.


To use segments with web banners, there are additional requirements:

1. The relevant segment must be created in the Segments tab.

2. The Meiro User ID attribute must be added to WBS - Please contact the Meiro team to set this up.

1.1. Select condition: “Segment”

1.2. Select the segment of your choice you wish to display a web banner to.

1.3. Select “Identifier attribute” which is an attribute used for profile stitching that helps to identify the user.

Usually, it is “Meiro User Id”.

1.4. Select operator “is in segment / is not in segment”.

1.5. Select “Identifier location” (cookie / local storage) and insert a “key”.

Those values are Meiro user IDs tracked from the client website where Meiro SDK is deployed.

Usually, it is a cookie, key:  meiro_user_id

Key can be found in the Developers tools -> Application -> Cookie/ Local storage -> Key

Warning: Setup for identifier attribute/ location and key can be custom to your use case, therefore please contact the Meiro team.


2. How to test a web banner for a segmented audience

To test whether the banner displays correctly to the segmented audience it is necessary to set the meiro_id of the customer belonging to the segment.


Warning: We strongly advise using only the fresh anonymous windows for testing different cookies!
