Live chat is extremely useful when you deal with customers. They can ask questions and get answers faster, because imagine if they can't easily find the information they're looking for - probably they will just leave your website. If the live chat representative has friendly attitude to current and potential clients, they will establish stronger relationship with them and can make you look like a trustworthy company. It can help you boost your sales, as the agent can give advice to people or help them choose the best product or service for them. Also, you can learn and upgrade your website on the basis of your clients' questions, requirements and so on.
