What does the term 'Custom Audiences' refer to in Facebook advertising?

The term 'Custom Audiences' in Facebook advertising refers to a feature that allows advertisers to target specific groups of users based on their previous interactions with the brand. This can include individuals who have engaged with the business through various channels, such as visiting a website, using a mobile app, or engaging with posts on Facebook or Instagram. By utilizing Custom Audiences, advertisers can create more personalized and relevant ad experiences, targeting people who are already familiar with the brand and increasing the likelihood of conversion.

This targeted approach leverages data that businesses have about their existing customers or those who have shown interest, allowing for more effective advertising strategies. Using Custom Audiences helps to maximize the impact of advertising spend by reaching users who are more likely to respond positively to the ads due to their prior interactions.
