Sainsbury’s has completed the upgrade of its groceries website to a new platform.

The retailer has been gradually moving the site over to new systems since October. The migration has been by region to minimise disruption.

New features include improved navigation so shoppers can search by favourites, special offers, new products and top brands; improved recipes that allow shoppers to add ingredients to their online trolley; and data-driven merchandising that allows Sainsbury’s to personalise offers based on what a shopper puts in their trolley.

“Taking into consideration the performance implications of the large number of items in the average shopping trolley, the sheer abundance and complexity of grocery promotions and data migration of eight million customer accounts, four million credit cards and 12 million orders, the launch has been a resounding success,” said Neil Stewart, CEO of digital agency Salmon, which did the work.

Sainsbury’s digital and technology director Jon Rudoe added: “It’s taken Sainsbury’s 14 years to reach £1bn annual sales online and this new platform gives us the capacity to double this.”
