Hi Joe,
I was reading your post and thought I would offer some advice. The business card is what is considered a proactive chat invitation. If you have reporting that shows where your chats are originating from you will see that the business card probably accounts for 70%+ of your chat activity. You don't want to stop using it because your chat volume will drop 70%+. You may even consider increasing how fast people see the proactive chat invitation to reduce site abandonment, and improve your chat volume. I recommend that you set the first greeting to 10 to 15 seconds, and let them remain up at least 15 to 20 seconds. I know I am an unknown on this form, but my company also uses proactive chat invitations, and based on our past 3 years of data, if you follow the advice I am giving you above you will increase chat and lead volume on your website. Please feel free to let me know your thoughts on this. I think if you check with ContactAtOnce they will agree with what I am saying. Based on what I am reading you are probably missing a lot of chat opportunities from the visitor that spends 35 seconds on a page if you have it set for 45 seconds. I know it has been a while since you posted the above info, and you may have already figured this out, but maybe someone else can benefit from this info.

Yes I agree with Shereef. His numbers are about the same as what we have found. The drop down business card thingy actually does really well. I would suggest it within the first few seconds and govern it to only show on specific pages. Home page is a biggie of course. As long as you have buttons on your site and you present the fact that you offer chat with the drop down business card thingy then once they cancel it out they know to look for a button if they want to chat later. The trend is not how many dealers are adding this chat to their websites but how many people are actually starting to chat with dealers. It has grown tremendously just in the past year I have been here.
