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 online 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.
