hello there. face is the most easiest way to ads for your site business work or you can ads for your products. if you dont know you should check market place where you can put your products with details to sell so anyone can reach you to buy. simpleFacebook's drawback I think is that people are not actively searching for your product. In that case, you're further down the line in the buying cycle and getting a buy would require a lot more work. Well, with PPC, on the other hand, if you're bidding on someone looking for a product with a long tail keyphrase, then you might get a buy - as that justified the expensive CPC.
