"Marketing through thought leadership is totally in right now. It makes sense: Every business wants to be perceived as a leader, respected by customers and envied by competition".

"Thought Leadership doesn't directly aim to sell, but educate, advise and in some case entertain", says Molli Bucini. However, for professionals and businesses, this is a marketing action.
There is no KPI yet directly measuring influence, reputation or Thought Leadership - no magic button on Google Analytics either. However, the basic Content Marketing analytics must be tracked:
- repeat visitors
- bounce rate
- mention and share
- and eventually in-site conversion.
All of them, and more, discussed in this post.
Reminds me of the situation of Social Media marketing some years ago: professionals and businesses realized they needed to be active on SM, before they could actually measure their impact (well... most professionals and businesses - this was not obvious for all, actually). Detailed ROI analysis matures as we progress, it's a step by step process. But we should not wait for a mathematical proof before we demonstrate our Thought Leadership through a relevant Content Marketing strategy.
Becoming a thought leader is not something that just happens. It takes work and strategic planning to achieve. The perfect pathway is not spelled out for anyone to follow. Content curation should definitely be part of one's strategy to become a thought leader in their industry.
