Well Nightwing,
I have tried many times to find this "link bait" examples for more specific industries but it was almost impossible to find successful stories unless you write an amazing post for your digital marketing company, post it on moz where will be seen by many others involved in digital and they probably will link to you.
What I am saying is that there are so many industries out there and for some of them certain techniques, practices just don't work because the audience doesn't really care about linking to what you write, and this gets even worse when you work for e-commerce site.
sorry about that, my English needs more improvement as my SEO skills.
