How to Build Relationships and Loyalty
Have you ever seen a food frenzy at the office? Someone brings in bagels or donuts and everyone is instantly hungry and can't stop thanking the generous giver.
The same way we maintain friendships - by giving of our time, our resources and ourselves is the same method to use for our customers. Potential customers need items that can make them remember your company brand or image. There needs to be a token of appreciation and some type of benefit - sometimes extraordinary gift giving, sometimes not so much. Almost always, it's the ordinary that maintains relationships - a chat, a note, showing up with popcorn, tea and cookies or a bagel and cream cheese.
If you want to stand out from the competition. There are so many others in your field that are not providing these small extras to attract customers and to make a connection with your company. This can help brand your company, and communicate your style of business.
