Launched a year ago, the platform combines Tesco Clubcard and in-store data insights with Dunnhumby’s data analytics.

Dunnhumby helped Tesco develop its Clubcard scheme in the 1990s. Tesco later bought Dunnhumby and there are now around 20 million Clubcard holders.

Brands and agencies can book ad placements through the platform, measure campaign performance and access sales reports.

The platform has expanded its self-service tools and media channels available to advertisers, with new partnerships with media owners including Pinterest.

Tesco has also expanded the range of advertising opportunities for brands on its website, including sponsored placements.

Tash Whitmey, membership and loyalty director at Tesco, said: “It is a big part of our strategy, through I Love my Tesco Clubcard, to better engage our customers and provide them a more personalised and responsive offer. We’re using our digital platform to create additional value and increase loyalty, making sure that the more customers use Tesco, the more useful it is to them.”
