Does co browsing have positive effects on the customer experience? Co browsing refers to the ability to have a contact center agent and customer jointly navigate an application (e. g., web page, digital document, or mobile application) on a real time basis through the web. A study of businesses indicates that 81 of 129 co browsing organizations use skills based routing to match the caller with the right agent, whereas 65 of 176 non co browsing organizations use skills based routing to match the caller with the right agent.
