First, you must draw out the Demographics of your Customer – age, gender, education, interest…etc.
Define Your Goal First : One way to avoid being overwhelmed by the Facebook Ads platform is by defining your objective upfront. Once you map out your strategy and define your goal it will be easier for you to select an objective when you start setting up your campaigns.
Personalize Your Campaigns : Select audiences that make sense to your offer and your objective and give them the right type of incentive. This will give you a greater chance of increasing conversions.
Your Research: One of the best ways to make sure that you are successful on each new campaign that you launch is by researching the results of similar brands promoting similar products on Facebook ads.
Finally,
Do Split Test Your Campaigns: Always test two or more variations of the same campaign, each one with different targets, or different copy, or different design elements, or both.
