Chat live with visitors on your website. No software for visitors to download. No account for visitors to open. Initiate a message from you directly to visitors on your website. Watch as they move throughout your site. You even know what phrase they entered in search engines to reach your website. Mark pages as hot pages and you will be notified by a beep when a visitor reaches that page. Then if they do not click your chat icon, you can initiate the chat yourself. This should give you a greater return if you are paying for visitors to come to your site.
This live chat system is also perfect for providing support to your clients. You can chat live with them or if you are not available, visitors can create their own support tickets.
