Use Automatic Chat Distribution (ACD) to automatically place operators in an active chat session without operator interaction.
For example, you can automatically invite visitors to chat with an operator when they have been on a particular page for a certain time, clicked a link or revisited a URL. Automatic Chat Distribution balances the number of visitors in queue and the operator's workload in order to keep the rate of invitations at a maintainable level and the operator's chat queue saturated.
