Congratulations on starting your new venture. I think you have a couple of different routes and I'm a firm believer of finding a platform that "feels right" to you and focusing your efforts on it. For me, my podcast gives me direct access to my target audience of entrepreneurs and I also target followers of major podcast influencers on Twitter with ManageFlitter. This allows me to continue delivering quality content through my show and driving downloads on iTunes while also furthering my brand awareness on Twitter. I use other social platforms but have really concentrated my efforts on exploiting said channels.

Maybe you consider a YouTube Channel, blogging and/or guest blogging for relevant platforms. Facebook is pay-to-play but undoubtedly drives the best results, in my opinion.

Whatever you decide, educate, engage and build awareness. Do yourself a favor and conduct some strategy research before you just dive in. Hope this was helpful, best of luck!

*Build your email list! Can't stress that enough. Find ways to capture emails through your content in the form of quick freebies, resources, etc.
