1. Customer File: A customer file custom audience allows you to upload a list of customer email addresses, phone numbers, or Facebook user IDs to create a custom audience. You can use this type of custom audience to target ads to specific groups of customers, such as loyal customers or high-value customers.
2. Website Custom Audience: A website custom audience allows you to create a custom audience based on people who have visited your website. You can use this type of custom audience to target ads to people who have shown an interest in your products or services, or to people who have taken specific actions on your website, such as adding products to their cart or completing a purchase.
3. App Activity Custom Audience: An app activity custom audience allows you to create a custom audience based on people who have taken specific actions in your mobile app. You can use this type of custom audience to target ads to people who have engaged with your app, such as making a purchase or completing a level in a game.
4. Offline Activity Custom Audience: An offline activity custom audience allows you to create a custom audience based on people who have interacted with your business offline, such as in-store purchases or phone calls. You can use this type of custom audience to target ads to people who have already engaged with your business offline, or to people who are similar to your offline customers.
5. Engagement Custom Audience: An engagement custom audience allows you to create a custom audience based on people who have engaged with your content on Facebook or Instagram.

By using these different types of custom audiences, you can create more targeted and effective ad campaigns that are tailored to the specific needs and interests of your audience.
