27 reasons case studies always make great content

Many people have opinions on what makes great content.  One  is case studies.  But case studies usually aren’t at the top of the list.  
They are generally listed behind your voice (e.g. be authentic, be helpful, be passionate, be transparent) and even grammatical advice (e.g give tips, ask questions, use subheads and bullets to make it easier to read). 
In my opinion, case studies deserve a higher place in the content pecking order.  
Within the last year, I’ve written a number of blogposts using case studies.  They attracted a stong readership.  They’ve brought in business.  Just as important to me, they created relationships with people all over the world who share the same interests.  Here are the posts and how they use case studies:

1. 34 case studies that prove social media ROI
2. Another 33 case studies that prove social media ROI
3. 16 case studies that proe social CRM
4. 6 social media ROI case studies with something in common, courage

It is fair to say social media and ROI are topics of interest too.  But these topics would be of little interest and value without substantiation from case studies and it is the case studies that make the topics come to life.

In my own case study work, I’d been inspired by the creative thinking of Joe Sorge, an owner of a restaurant and hospitality chain that includes AJ Bombers and a founder of Kitchen Table Companies that helps small buisnesses and the resourcefulness of Mari Luangrath, the owner and founder of Foiled Cupcakes.
They have written back to elaborate on their stories and personal values.  It taught me the #27th reasons case studes always make great content; they build relationships and create friendships.
