How can I produce a good facebook ad ?

Hi Friends, a long time i registered in here and now i will post continously

So i set up a Dropshipping Store with Shopify. Its a store about LED Lamps, flashlights and so on...
I need to set up my first facebook ad, but how can I find targets for the object i want to market ?
For example I have a moonlamp thats thing is great, but which targets like moonlamps ?

how do you start with something like that ?

thanks

When setting up your Facebook ad, Facebook will give you the chance to choose and analyze your target market. It will help you narrow down your reach by interests. The age group can be quite challenging, but of course, target the age of millennials, young professionals, and the list goes on. Facebook will give you all the options you can get before launching your ad -Micah
