### Limitations and Considerations about Meta Rules
The guidelines and requirements for custom audiences on Meta are subject to frequent changes. Because of this, we always recommend consulting the [official Meta documentation](https://www.facebook.com/business/help) to obtain up-to-date information on the rules for creating and updating audiences.
Below, we highlight some practices adopted by SprintHub to facilitate the creation and updating of custom audiences on Meta, reducing the need for manual uploads:
* **Automatic Update:** SprintHub automatically inserts each lead into the custom audience as soon as they enter the segment, even if the total number of leads is less than 100. This allows the audience to form gradually.
* **“Filling” Status:** Until the audience reaches the minimum of 100 leads required by Meta, the status in the Ads Manager may appear as “Filling”. However, all added leads will be recorded and ready to be included in the audience when the threshold is reached.

### Practical Cases
* **Broad Audience (4,000+ leads):** With a large audience, above 4,000 leads, it is possible to create a lookalike audience and target ads to that group, even though the status may appear as “Filling”.
* **Small Audience (33 leads):** With an audience of 33 leads, it is possible to create a lookalike audience, but Meta does not allow the use of that audience in ads until the number of leads reaches the minimum of 100 required.
This approach reduces the 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:** Monitor lead entry directly in Meta. On some occasions, a lead may not appear in the SprintHub segment due to lack of information.
* **Custom Segment Identifier in Meta:** The segment identifier is the ID, available in the Meta leads list.
* **Recreating Audiences on Meta by SprintHub:** By following the previous steps, the audience will already be recreated automatically on Meta. Note: deleted audiences cannot be recovered.
* **Changing Segment Name in SprintHub:** Name changes in the SprintHub segment only reflect in Meta during audience creation. Subsequent changes are not automatically updated on Meta.
