What are custom audiences and how can I create them?

Custom audiences are a targeting option in Facebook Ads that allow you to reach people who have already engaged with your business in some way. Custom audiences can be created using a variety of sources, including website visitors, email subscribers, app users, and Facebook engagement.

Here are the steps to create a custom audience:

1. Go to Facebook Ads Manager: From your Facebook account, go to the Ads Manager and select "Audiences" from the top menu.
2. Create a new custom audience: Click on the "Create a Custom Audience" button.
3. Choose a source: Select the source for your custom audience. Here are some examples:
* Website traffic: You can create a custom audience based on website traffic using Facebook Pixel. You can target people who have visited your website, specific pages of your website, or who have taken a specific action on your website.
* Customer file: You can upload a customer file, such as a list of email addresses or phone numbers, to create a custom audience. Facebook will match the data in your file to Facebook user profiles.
* App activity: If you have a mobile app, you can create a custom audience based on app activity, such as people who have installed your app or taken a specific action within your app.
* Engagement: You can create a custom audience based on engagement with your Facebook content, such as people who have engaged with your Page, videos, or events.
4. Define your audience: Once you've selected a source, you can define your audience by setting rules and filters. For example, you can target people who have visited a specific page of your website in the last 30 days.
5. Name and save your audience: Once you've defined your audience, give it a name and save it. You can use your custom audience in any of your Facebook Ads campaigns.

By creating custom audiences, you can reach people who have already engaged with your business and are more likely to be interested in your products or services. Custom audiences can help you improve the relevance and effectiveness of your Facebook Ads campaigns.
