User experience: the secret to word-of-mouth

The definition of a good strategy relies on a great user experience. A high-performing e-commerce site must reduce theeffort deployed by the customer to achieve satisfaction. If the work on the interface is done well, the conversion rate for repeat visits soars.

The loyalty program of the past (like loyalty cards) is still useful, but the new standard is emotion. By creating a positive atmosphere , you encourage your customers to generate word of mouth, the most powerful growth engine in the industry.
