I was having issues in my online store with customers abandoning their shopping carts and I couldn't figure out why. I started to use chatbots by Tidio so when the customer was about to abandon, the bot was triggered and offered a discount code. This helped increase my sales by 65%!
Tidio really is the best chatbot I have come across. There's so many out there but they're difficult to program. This is just easy and does the job well. I'd highly recommend you give it a go. There's a 7-day free trial too.
One of the more difficult and time-consuming things is getting your bot working well. The interface from Tidio is great for this and with its visual editor, the learning curve is not too big. I'd recommend this to beginners and advanced users alike.
