For Facebook export, that will be one of the following:

Meiro Integrations

(required)

"MI workspace" refers to the workspace in Meiro Integration, which will be executed when the segment is exported.

To run exports, you need to know the name of the workspace. You should get the name of the respective workspace from the Meiro data analyst.

Meiro data analyst handles the Meiro Integration's workspace preparation and data transformation for a specific destination (e.g., Facebook, Twitter, Google Analytics). Each destination requires a different (very specific) data structure.

Parameter: 

Audience Name

(required)

Facebook destination requires setting up an Audience Name parameter. A business user must fill in to export a segment to a Facebook Audience.

Learn more: The audience is a selected group of your customers that you wish to communicate with. To learn about Facebook audiences, please refer to the official Facebook documentation.

Exportable shows how many customer profiles will be exported to your destination.

This number is defined by the conditions you choose to segment the audience and mandatory attributes set up by the administrator (that must be present to export to your destination).

For example, if you segment 1000 profiles, but only 10 have mandatory attributes present, only those ten will be exported to your destination.

Mandatory attributes are visible in the Data Library/ Destinations tab.

For Facebook Audience, those are the mentioned below:

• Email address,
• Phone number,
• Advertising ID.

Customer profiles where the above values are unknown will not be exported to Facebook Audiences.

Parameters

Audience Name (required)

The name will be visible in Facebook Audiences as the name of the exported audience.

Audience ID (optional)

"Audience ID" defines which audience will be updated or if a new audience will be created:

• If the Audience ID is left empty, then a new audience ID will be created.
• If you fill in an existing Facebook Audience ID (which can be obtained from the Facebook Business Manager), that audience will be updated/ overwritten (not incrementally).
  
  

Warning: You can only update an existing Facebook audience if that audience was previously created through export from the Meiro. If an audience was created manually in Facebook Business Manager, that audience will not support the load of external data, hence it will not be possible to update that audience.

Remember: Each export from Meiro to a preexisting Audience ID will replace the previous audience and not load incrementally. 

Retention days (optional)

The number of days to retain before the audience expires and is removed. You can now set this value for both new and existing audiences, allowing you to extend or modify the audience retention period as needed.

• When creating a new audience, you can specify the desired "Retention Days" value, which can be set for up to 180 days.

• If left blank, the audience will not have an expiration date, meaning it will remain active until manually removed.

• For existing audiences, you can also update the "Retention Days" parameter to change the audience's retention period, ensuring it aligns with your campaign needs.

Export your segment manually by clicking on the Export button or set up a schedule (optional) so your export will run at scheduled times.

Schedule export to the same audience in Audiences/ Facebook Business Manager:

1. Create a segment and fill in the Audience Name. This name will be visible on Facebook.
   
   

   

   
   
2. Click on the Export button.
3. Then go to Facebook Business Manager.
4. Find your new audience created and exported in Facebook Business Manager.
5. Copy Audience ID  from Facebook Business Manager and paste it to the Audience ID field in the parameters sections in the Meiro segment builder.
   
   
6. Set up a schedule as needed, and all exports will be exported to the same Audience ID.

Are any limitations of Facebook Audiences possible to load?

Facebook only allows the creation of up to 500 Custom Audiences per ad account. Any custom audience of more than 500 will result in an export error, and old audiences must be deleted.

What customers' data is exported to Facebook (mandatory & exported attributes)?

Meiro exports to Facebook:

• Email
• Phone number 
• Advertising ID

Those are mandatory attributes needed in order to export to Facebook Business Manager.

Possible to export (if known)  is also:

• First name
• Last name

Exported data is set by the administrator. To see which attributes have been set to export, please go to the Data library/ Destinations tab, exported attributes. 

Warning: The number of exported customer profiles will not be the same as the number of "rows" visible in exports on Facebook. It is because rows are not customer profiles but identifiers. 

How long does it take to export? 

Export happens in real-time, and usually, it is a matter of minutes.

Will multiple exports overwrite existing ones or load as new ones? 

Multiple exports with the same name will appear as new custom audiences (separate) with the same name on Facebook.

Warning: There is no limit on API calls. If you experience any trouble, please contact the Meiro team.

Match rate

Facebook shows a match rate for audiences of more than 1000. If you export an audience of fewer than 1000, or if out of your audience, fewer than 1000 are matched, then the audience size will show up as “Below 1,000 - Small after matching”. However, your custom audience can still be activated if the availability is Ready.

How do I delete custom audiences on Facebook?

Detailed steps can be found on the Facebook website.

What is the difference between FB custom and anonymous audience?

FB Custom Audience allows you to define an audience based on criteria such as CDP, but the audience can be identified through their name, email, or phone number.

FB Anonymous Custom Audience is defined but not identified, meaning that the audience does not have a name, email, or phone number. Instead, we retarget them based on their FB client ID.
