I'm a self-published writer and want to market myself as a brand to my target audience. In social media marketing, is it better to
- use only one platform (e.g. Facebook or my own website) and publish all my news, blog posts and images there,
- publish the same content on several platforms, or
- publish different content on different platforms (e.g. "private" news and images of myself on Facebook, photos I took on Pinterest, stuff I like on Tumblr, how-I-write blog posts on Blogger, instructional videos on YouTube, artistic videos on Vimeo, questions and answers on ask.fm, etc.) and connect everything through link lists in each platform's sidebar?
I ask this, because personally, when I find someone interesting, I dislike having to hunt for all their activities across all the net, never knowing if I have missed something interesting or important, on the other hand, if their website or Facebook profile is all someone has, they don't appear very interesting because I have quickly exhausted their depth.
So, what strategy works best? If you can, don't just post your private opinion, but quote research or expert publications, or give successful examples (and successful counter examples).
