WhatsApp chat-in QR codes work best where people have a chance to scan them. They can be on posters in your store or flyers added to products you send out, ideally providing an incentive like a discount or early access to sales or new products. If your website has a lot of traffic from desktop (as 45,6% of all global website traffic still was in 2021), adding a QR code to your product pages or thank-you pages might add value, too. QR codes help customers enter the chat via their phones by simply scanning the QR code in case they aren’t using WhatsApp Web and thus can’t click the wa.me link to be taken to your inbox.
