A customer clicks on the link with your phone number and enters his phone number. You will instantly get an email notification about this with all available customer details. Then you can bring more information about the product and answer all the customer’s questions when you call back over phone, Viber, WhatsApp or any other messenger. No matter how much information you put on your website, most visitors won’t take the time to read it all.  Time saving convenience is a key factor in customers making a decision. This is why it’s so important to offer callback options. It’s easy, and lightweight, for a customer to simply request you call them back. No waiting on hold, no waiting for a live chat agent, and best of all, no waiting for a “contact form” email reply.
