Here are few points to remember while building the conversation flow of your chatbot inorder to get better interaction and conversion rates-
Keep your messages short and crisp.
Start the conversation with an easy question -basic yes or no question
Try to convey what your product does in simple language
Make it more visual- using images and videos
Keep in mind the mentality of your customers, so you can ask relevant questions
Always ensure that you give some kind of value in return when you ask for any information like phone number/ email id. Or make it clear as to why you need this information. This way they will be more willing to share the information and the conversion rates will be higher
