Good point about content quality being part of maintaining the bot. For a small business, a short, dated fact list (prices, hours, policies) that you review on a set day each month goes a long way, and it helps to tell visitors clearly that they're talking to an AI. I'd also log every question the bot couldn't answer and add those answers weekly, since that's where the gaps show up. When it does hit a gap, collecting the visitor's name and contact details for a human follow-up feels much better than a vague "I'm not sure", especially for after-hours enquiries.
