My DH and I have set up a small business and we we have an on line presence (FB,twitter, website) how/ where can I learn to optimise these channels? I'm a trad marketeer by prof but I've been out the loop for a while and I'm certainly no digital marketeer so need to learn about ppc, google Adwords (I think) and the like. We need to start pushing this business now as it's seasonal so any help appreciated
