To do this, I often align the launch of my content with a couple of guest posts on relevant websites to drive a load of relevant traffic to it, as well as some relevant links. This has a knock-on effect toward the organic amplification of the content and means that you at least have something to show for the content (in terms of ROI) if it doesn't do as well as you expect organically.
And executives in particular, whether you’re getting help from an external coach like myself, or have an internal expert that can help them with their profile, this is really important because your executives are the key to really building thought leadership. I know even at Act-On, Bill Pierznik has been making some really amazing posts on LinkedIn around his thoughts on the business world, and it’s garnered a lot of engagement. So, the more you could have your executives be the voice for your company and really get their profiles up and running, the better.
