Best Practices for AI Chatbots
- Always offer human escalation: Give users a clear path to a human agent for complex issues
- Keep the knowledge base updated: An outdated knowledge base leads to wrong answers that damage trust
- Set clear expectations: Tell users they are chatting with an AI from the start
- Review conversations regularly: Analyze what the bot fails to answer and add that content to the knowledge base
- Personalize by page: A chatbot on a pricing page should focus on conversion; one on a support page should focus on resolution
