Instead of using chatbots, I would recommend you try the services of managed live chat from Chat Metrics (chatmetrics.com) as you will get human agents who will be available on your website 24/7 to instantly answer the questions and queries of your website visitors and provide them with the right solution. You will be able to double up your generated leads within the shortest time without any hassle.
Yes, I have used interactive chatbots in the past. However, to my disappointment, I was not able to get the results I expected. So then I tried live chat services from Chat Metrics (https://www.chatmetrics.com/). To my surprise, I was able to get more leads and bookings within a brief period of time. Wondering how? My website visitors got to interact with human agents when they had a question regarding my service. So these agents would instantly answer them and direct them in the right direction, doing what a sales and marketing individual would.
