As part of the deal, SCL Analytics will use Unica Corporation's Affinium NetInsight software to add web analytics to the tourism body's e-commerce work.
Visit Britain has around 1m unique users across its network of more than 40 sites globally and a key focus of SCL Analytics work will be to gain better information on site visitors and to improve customer services and partnership working.
Harry Speller, customer experience executive at VisitBritain, said: "This integration will provide us with the information we need to ensure our website is providing valuable products and services for our visitors from around the world."
Alan Hall, managing director of SCL Analytics, added: "Using web analytics to gain insight into its online shops will not only help VisitBritain improve its revenue, but to extend its reach and provide better customer service."
Meanwhile, VisitBritain will also be taking a free webinar called ': the dark art of advanced web analytics', alongside Unica and SCL Analytics on July 10.
