Just recently, we experimented with a business partner of mine using Facebook pixel and Amazon embedded URLs and the results we got, were quite fascinating. CTRs averaged 5% to 15%, which was not bad at all considering we had split tested both campaigns at a total daily spend of $10 per ad.
Facebook PPC especially when connected to amazon selling has shown a lot of success in recent year.
This is where create a Facebook ads and then link it to your Amazon page such that people are being directed there to make a purchase.
It's pretty easy if you know what to target. You just create a campaign on Facebook, select your objective and audience demographic, and are good to start testing.
With a good campaign on Facebook PPC you should be able to advertise yourself nicely through their social network. I recommend you try.
If you have money to sponsor PPC advertising, one of the best ways is to promote through Facebook.
