Why did a customer terminate her visit to a retail web site before ordering the product she was examining? Tealeaf Technology, recently purchased by IBM, captures and records what each customer is doing and seeing in real-time on every page and across all site visits, down to the page-by-page, browser-level experience. By capturing every customer’s visit, as well as the reaction of the site in response to requests, the technology captures both quantitative and qualitative details of every single interaction. Acting on these insights can then increase the number of visitors who become customers.
