L’Economist ha scoperto che certi siti di ecommerce ne sanno una più del diavolo
The internet, by allowing anonymous browsing and rapid price-comparing, was supposed to mean low, and equal, prices for all. Now, however, online retailers are being offered software that helps them detect shoppers who can afford to pay more or are in a hurry to buy, so as to present pricier options to them or simply charge more for the same stuff.
Cookies stored in shoppers’ web browsers may reveal where else they have been looking, giving some clues as to their income bracket and price-sensitivity. A shopper’s internet address may be linked to his physical address, letting sellers offer, say, one price for Bel Air, another for Compton. Doug Bryan of iCrossing, a digital-marketing consultancy, explains that the most up-to-date “price customisation” software can collate such clues with profiles of individual shoppers that internet sellers buy from online-data-aggregation firms. All this is fairly cheap, he says.
One of the few big online firms to admit to using such techniques is Orbitz, a travel website. Its software detects whether people browsing its site are using an Apple Mac or a Windows PC and, since it has found that Mac users tend to choose pricier hotels, that is what it recommends to them. Orbitz stresses that it does not charge people different rates for the same rooms, but some online firms are believed to be doing just that, for instance by charging full whack for those assumed to be willing and able to pay it, while offering promotional prices to the rest.
