If you are thinking about using facebook ads to advertise your business, here are a few things you should know. Facebook is the only company in the world that the more you spend the higher prices you pay. It was pretty much designed by a bunch of idiots. Keep an eye on your cost per click. It will double and triple for no reason.
If you are going to advertise multiple items, YOU WILL compete with yourself and drive up the price. Best of all, if you turn off an ad because your cost has gone up, it will turn it self back on and overcharge you. So basically if you are going to advertise with facebook, be ready to be overcharged.
Get used to getting bent over as they do not care one bit about their paying customers. I highly recommend going to google ads or finding another avenue of advertising. GOOD LUCK
