### Limitations and Considerations About Meta Rules

The guidelines and requirements for custom audiences in Meta are subject to frequent changes. Because of this, we always recommend consulting the [official Meta documentation](https://www.facebook.com/business/help) for updated information on the rules for creating and updating audiences.

Below, we highlight some practices adopted by SprintHub to make it easier to create and update custom audiences in Meta, reducing the need for manual uploads:

* **Automatic Update:** SprintHub automatically adds each lead to the custom audience as soon as it enters the segment, even if the total number of leads is below 100. This allows the audience to be built gradually.
* **"Populating" Status:** Until the audience reaches Meta's minimum of 100 leads, the status in Ads Manager may appear as "Populating." However, all added leads will be recorded and ready to be included in the audience when the limit is reached.

### Practical Cases

* **Large Audience (4,000+ leads):** With a large audience, above 4,000 leads, it is possible to create a lookalike audience and target ads to this group, even if the status may appear as "Populating."

* **Small Audience (33 leads):** With an audience of 33 leads, it is possible to create a lookalike audience, but Meta does not allow this audience to be used in ads until the number of leads reaches the minimum of 100 required.

This approach reduces manual upload work, but since the rules may change, we recommend reviewing Meta's guidelines periodically.

### Common Questions

* **Linking the Meta Audience to the Segment in SprintHub:** Track lead entry directly in Meta. In some cases, a lead may not appear in the SprintHub segment due to missing information.
* **Custom Segment Identifier in Meta:** The segment identifier is the ID, available in the Meta leads list.
* **Recreating Audiences in Meta via SprintHub:** By following the previous steps, the audience will already be recreated automatically in Meta. Note: deleted audiences cannot be recovered.
* **Changing the Segment Name in SprintHub:** Name changes in the SprintHub segment are only reflected in Meta during audience creation. Later changes are not automatically updated in Meta.<br>

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.
