A few hours a day is whats best for daily scheduled content, sourced from the clients themselves, daily trending topics, feedly and klout and other tools. My social media management work starts with a close study of existing audience demographics on each platform, followed by a simple plan for the future of each platform. From there, we use the plan and simple scheduling and tracking tools - my preferred tool is Buffer, but I can also use hootsiute or another if your team of your clients prefer - to create regular content. Then I can start working a quick hour or two each morning to create your content.

I've worked first as social media manager at a few small organizations, and also worked with Youtube production company Funhaus for 3 months, where I learnt about tracking engagement, and youtube monetization etc. Then most recently took over as the social media manager of a successful Boston startup. They were really struggling to put any constantly content up and improve their search terms - after working an hour a day for about 3 months I had increased twitter impressions by 54% and profile visits by 69%. Facebook post reach had gone up by 82%. Although this last number seems ridiculous, going from an inactive Facebook page to me working on content, I created 76x the average monthly Facebook engagements. Let me do something like this for you and your clients, too
