About reaching new audiences

When choosing a target audience for your ad set, you can either create a new audience or use a saved one.

These are the options available for creating a new audience, which you can find in the Audience section of ad set creation:

• Locations. Target ads to people based on locations. You can select country, state, province, city, congressional district, zip and post codes. Most objectives let you target worldwide (type in "worldwide"), by region (for example, "Europe"), by free trade area (for example, "NAFTA", the North American Free Trade Agreement) or by app store availability (for example, "iTunes app store countries").
• Age. Target ads to people within an age range.
• Gender. Target ads to women, men or people of all genders.
• Languages. Target ads to users of certain languages.
• Detailed targeting. Include or exclude people from an audience based on criteria such as demographics, interests and/or behaviours.
• Custom audiences. Custom audiences are select audiences of people you already know that created from information you provide or from information generated across Meta technologies. You can create custom audiences from a list, the Meta Pixel, the Facebook SDK and engagement across Meta technologies.
  

Note: You can also use custom audiences to create lookalike audiences. A lookalike audience is an audience that we create based on a custom audience source that finds other people across Meta technologies who are the most similar to the people in the source.

You can include or exclude people in a Custom or Lookalike Audience from the audience you want to reach.
