After I upload a new image to FAA I then use the Pinterest, SU, facebook, G+ and whatever icon to advertise my new painting.
SU and G+ don't provide me with any warm fuzzy's. Thus far I don't get feedback or notable views/sales from these platforms and I am sure a LOT of that is that I don't use them to their full advantage, since I haven't taken the time to learn how.
I enjoy the Pinterest user friendly platform and my growing followers. Just recently, a Pinterest user saw one of my paintings and followed the link back to FAA to contact be to buy the original. Thus far, FAA and Pinterest are best at marketing for me.
I also just opened an Etsy shop that seems to be gathering some views.
