What does the term value mean

Having been working with new CSM's both internal and external one question I get asked is what does the term adding value mean. Below I have listed a few points what value means to me and how I "add value to customers 

Value for me is the ability to provide a customer something they cannot get/find themselves i.e Product/Industry information or experience.

How do I add value to my customers?

• Provide the customer with industry or product information they cannot find elsewhere (An example I provide is The best day to post your adverts looking at our industry and site data is
• Provide a positive experience to the customer 
• Collect and apply feedback
• Gather and share social proof (Customers competitor information to help justify decisions)

Has anyone got any other ways they add value to their customers
