I allow and even encourage my visitors to have a chat with me whenever I am online on my website:
http://prowebsecrets.com/This way I can engage, sell and support my visitors more efficiently.
I got a Business account from SnapEngage, which is enough for my needs, but there are plans for even more demanding Businesses.
What the Business account includes is 4 chat licenses, which is enough for me at the moment.
What SnapEnage allowed me to do is to focus on way more my visitors and a bit less on trying to optimize every single detail of my website, like design and copy.
It has been my experience that every visitor/customer is different, and without interacting with customers on a human level it's hard to cater for the uniqueness of each one.
With all the features that SnapEngage has, I am able to do stuff like set proactive chat triggers, which make it possible to send automated messages to people while they are browsing the website based on a number of factors, including their location, page, and even set JavaScript variable triggers.
Finally I can put live human beings on any website I have.
This is what SnapEngage ultimately allows me to do.
