AB InBev claims sales through its Stella Pear Cidre Facebook page have rocketed since adding Slingshot in August.

The new tool lets customers add items to online baskets at Tesco, Sainsbury’s, Waitrose and Ocado with one click on any advert.

AB InBev declined to reveal exact figures, but said that introducing Slingshot had doubled the conversion rate it would have expected from a product page on Amazon, which is usually between 3% and 5%.

“Shopping habits are changing as consumers embrace the multiple channels that offer purchasing opportunities,” said AB InBev head of consumer connections Ken Valledy. “We aim to meet our consumers’ needs through our innovations, whether that’s product development or embracing new ways of doing business.”

Slingshot MD Mitch Vidler added: “Online shopping is meant to be fun and intuitive, but many consumers are not yet getting the experience they expect. This is why a forward-thinking brand like Stella Artois and their consumers are benefiting from Slingshot - online grocery shopping should not be a chore consumers have to allocate time to.”
