I believe that facebook is a wiser option to advertise your products.
Facebook is a great social media page where not only could you advertise through chatting with your friends but also sharing your products to the public.
Here are some simple and effective ways to advertise:
1. Start with facebook messenger. Whether it is a webpage or just a product that you want to sell you could always share the links or photos with your messenger and not just with close friends but you could also share with all of your friends on facebook. An average user has about at least 800-1000 friends. You could spread the news to as many as 1000 people.
2. Friends of friends. You can also add "please share" to the captions so that your friends would know that you need them to share your advertisement if they aren't interested but still wants to help you out. I'm not saying that all of your friends would share your advertisement but at least your close friends and relatives would be able to share your advertisement to all of their facebook friends and again an average person would most likely have 800-1000 friends on facebook.
3. Advertising groups. There are many groups of facebook that you could join to sell or advertise your products or website or company. I recently joined a group that only sells guitars and guitar equipment and I could also post ads on the group if I wanted to provided that it's related to the purpose of the group. Anyway, what I'm trying to say is that you could find group pages and jin them so that you could advertise whatever it is you are trying to advertise.
There are many more ways to advertise on facebook and it's all up to you Just be creative on how you try to do things.
