What is the best way to win lasting customers loyalty?

Treat them like king, give more attention to existing customers expecially and most importantly produce base on customers demand in terms of quality specification standard.

I think it is a series of several episodes and each episode in which it is no less important than the other you always have to develop and activate the work and monitor it periodically and continuously whether in the products or offers distinguished from the rest of the competitors, and stick to the dates with customers, and the honesty of promises and seriousness of commitment, and transparency of the response that The heart of trust always and the comfort of customers, the softness of the treatment, and the excellence of the rest of the competitors, whether in products, prices, quality or commitment or the appearance of the people belonging to the institution or the company and the good treatment that is embodied in their behavior and morals I think they are advantages that bring continuity with the old customers The market opens up to new customers as I think every missing link of this series is able to destroy trust between customers.

Serve every customer in the same way, in which I would like to be treated as a customer.
