Marks & Spencer is to unveil a revamped website tomorrow, as the retailer holds its first investor day in nearly a decade.

The revamp of follows customer feedback and testing, and includes the upgrading of its core functionality and design.

Key changes include videos from the catwalk, actual fabric swatches and a carousel image suite to bring clothes to life. The site will also include stock availability information when customers select their sizes.

The site will have a more powerful and flexible search facility and include ratings and reviews. A wider screen will allow M&S to create more vibrant landing pages.

Shoppers will also be shown suggestions on how to mix and match and a pop up basket will allow customers to automatically view and buy their selection without being diverted from their shopping page.

M&S Direct director Dave Hughes said: “We’re very excited about the changes we’re launching tomorrow as they will dramatically improve the customer journey from browsing to basket. We’re certain this will give our customers more confidence when buying with us and attract new shoppers to the site.”

M&S will also expand Shop Your Way – a tool whereby shoppers have the flexibility to place clothing, beauty and homeware orders in stores, online or over the phone, from home delivery, or free delivery to their nearest store for collection. In the next month it will extend Shop Your Way from 46 to 163 locations.

Steve Rowe, director of retail and M&S Direct, said: “’Shop Your Way’ is central to our multi-channel strategy so that we reach new generations of customers in a way that is convenient for them. It’s already proven incredibly popular with customers particularly in our smaller stores that perhaps don’t offer the full range of M&S products.

“As a result of this success, we’re now extending ‘Shop Your Way’ to another 106 main chain stores and 11 Simply Food stores to help make our customers’ lives easier, especially in the run-up to Christmas.”
