Hi I would not rely soley on facebook as it only shows about 1% of for posts to your followers. It’s fine as part of overall promoting package but not much use if you only use facebook.
Have you noticed the icons for Stumbleupon, twitter and pinterst those are direct links. You will have to open accounts with them first.
Also try google+ and wanelo.
There’s craftjuice and then look into the Showcase part of the forum. You will find weekly and daily listing threads where we show what we’ve listed and agree to promote each other.
As individuals our reach is limited but when we work together our reach increases.
All the best
