e-commerce, social media, UK/Australia

hi all,



I have a website that sells extra virgin olive oil (if you want after you leave the link, I would not be accused of spam, in the first post)



My questions:



I am interested primarily in the UK market: Have you advice about the best social media strategy for the united kingdom? (gplus? FB?)



I would be interested also in the Australian market. Do you have experience of e-commerce sites on this market?



thanks
