I'm planning to add a Live chat service to my website, which would be a SEO company website. I would like to know if there are any easy to implement services, if yes, how would they work and how would be the pricing?
I am using the live chat system that came with www.focalscope.com. They have a free edition so, price wise, it is hard to beat. I found the chat module was easy to install and has loads of features: logging, analytics, etc.
Check out ClickDesk - it's cloud based, no software installation, easy integration with Skype and Gtalk. Very low pricing. Free plan available and paid plans start at $9.99. URL - http://www.clickdesk.com/
I would recommend Zopim. I really liked zopim and it has lots of useful features.
