You define the rules for where your ads are delivered with Core Audiences. Based on the following parameters, you may make your target audience as broad or as narrow as you like.
Advertise where you want to do business in the cities, communities, and nations where you want to do business.
Demographics-You can segment your audience by age, gender, education, job title, and other factors. You can track the demographics of the people who see your advertising, but
Facebook will never reveal personally identifiable information about them.
Add the interests and hobbies of the individuals you want to reach with your ad — everything from organic food to action movies – to make your targeted advertising more relevant.
Behaviour-Advertise to customers based on their previous purchases and device usage.
Connections-You can choose to include or exclude people who are connected to your Facebook Page or event to reach new audiences.
