Pro Tips to Get the Most Out of WhatsApp Chat
1. Set a Helpful Pre – filled Welcome Message
Instead of a blank chat, pre – fill it with something like: “Hi MagentoBrain! I visited your store and have a question about [product].” This reduces friction and gets the conversation started immediately.
2. Enable on Both Mobile & Desktop
Don’t limit the button to mobile only. Desktop shoppers also want quick answers – especially for high – ticket items. Enable it on both for maximum reach.
3. Place the Button on the Right Side
The bottom – right corner is where most users naturally look for chat support. It’s the standard UX position and gets the most clicks – especially on mobile.
4. Respond Quickly
A WhatsApp button only works if someone answers. Set up WhatsApp Business on your phone with quick replies and away messages so customers always get a response – even outside business hours.
