I am co-founder of Big Data & Cloud solutions venture. I have been working on building marketing presence for our firm which can help us build our brand as well as serve as lead generation source. The primary medium we use is LinkedIn both for reach out to prospects as well as content distribution for engaging with users. I would like to know from other folks out here on what all mediums are being used for B2B marketing and their effectiveness. I have also used Google Adwords for sometime but i don't think it works for in our case. Also would welcome details on lead generation sources that have been successfully used.
