Many companies have invested heavily in the past twenty years in loyalty schemes, particularly in the retail and travel markets.
But recent research has suggested that this has had little impact - with only one in four UK consumers professing strong loyalty to their favourite brands.
More interesting are the regional variations the research uncovers, with strong loyalty at 33% in the Tyne Tees area but only 20% in Scotland. Why is this?
Nectar is the UK's largest customer loyalty programme, and since its launch in 2002, more than ten million UK households regularly collect Nectar points.
The Nectar website, which allows users to spend the points they have earned on everything from CDs and DVDs to discounts on holidays, has recently relaunched with a view to improving usability.
We caught up with Roger Sniezek of Loyalty Management Group (which owns and operates the Nectar brand) to find out more about the site's relaunch.
