I had to explain this question to the board this week. We’ve done customer surveys for years, but were always surprised when customers who declared 90 per cent satisfaction would defect to a competitor.

I previously worked for an energy company at a time when people were switching supplier in their droves. I conducted analysis on the satisfaction levels of different groups – those who were new to my brand, had recently complained, had announced they were leaving, and had not been in touch for years.

Those most satisfied with our service were the ones who had complained because we had addressed their concern. The least satisfied were those new to the business because changing supplier was a hassle. Those who had announced they were leaving were no less satisfied than anyone else – “it was price what done it”.

Years later, I worked for a travel company. After every holiday, we asked customers what they thought of their experience. Analysing the stats one day, we split the responses into two and drew two graphs, showing satisfaction with everything from the hotel, the resort, the holiday rep, airport check-in times and food on the plane. One graph was several percentage points above the other one for every measure. And the two graphs? The weather seemed to affect responses – if the sun shone, they felt better about the firmness of the bed and the flight delay than if the weather had been miserable. Marketing often gets asked to do many things, but correcting the weather is pushing our skills somewhat.

In today’s social world, the problem will get even tougher, with customer loyalty influenced by what peers and non-peers say about your brand. So, while I don’t believe there’s a link between customer satisfaction and loyalty, I do believe there is one between dissatisfaction and disloyalty.
