This quote speaks to the fact that we, as salespeople, must make ourselves available and push valuable content out on all relevant media platforms (email newsletters, social media, etc) to help our customers as they make purchasing decisions.
The key is to not be “salesy” with your content. Educate your customer, provide value, and give them the resources that they need to figure out which company provides the best solution to their problem. Sometimes it will be yours, and sometimes it won’t. However, I can guarantee that if you provide the best resources and help throughout their buying journey, you will have a distinct advantage over the competition when it comes time for the client to pick a partner.
