gives the customer assurance they have reliable support available.
because a site has Live chat this does not mean they give reliable support
That's true, maybe I should've worded that differently. It doesn't mean they give reliable support - the actual experience and support will determine that.
it should be working 24/7. An "offline livechat" will create the opposite effect.
Been thinking about incorporating live chat here also. I agree it doesn't have to be 24/7 but a live chat that's never available or a live chat where the responses come at a snail pace also have negative effects. And don't get me started on those chat bots lol. @easyhostmedia, that would be great where the chat doesn't show offline but just disappears. Will look into that.
Most live chat providers will have an option to make the chat window non visible if offline
