Suppliers and retailers can now track product sales and market share in real time, MySupermarket has claimed.

MySupermarket’s Unique Insight Service, launched this week, provides daily sales figures for brands and categories at 11 UK retailers.

The resource tracks purchases at online shops to provide insights into shopper behaviour. MySupermarket CEO Gilad Simhony said it would be particularly useful for brand managers wanting to judge campaign success at different supermarkets.

“For the first time, marketers will be able to directly link the performance of their marketing campaign and impact on market share.”

The service covers Tesco, Asda, Sainsbury’s, Aldi, Morrisons, Iceland Ocado, Waitrose, Superdrug, Boots and Poundland. It hopes to add Lidl soon. The data is from over 50,000 unique monthly shoppers and 4.5 million visitors.
