AI Chatbot Best Practices: Building Bots Users Love
Most chatbots frustrate users. Here’s how to build one that doesn’t.
The User Experience Gap
68% of users have had a frustrating chatbot experience.
Common complaints:
- “It doesn’t understand me”
- “I can’t reach a human”
- “It keeps repeating itself”
- “It’s useless for my problem”
Core Design Principles
1. Set Clear Expectations
Tell users what the bot can do:
Bad:
“Hi! I’m here to help!”
Good:
“Hi! I can help with order tracking, returns, and product questions. For other issues, I’ll connect you with our team.”
2. Understand Intent, Not Just Keywords
Use AI to grasp meaning:
User: “Where’s my stuff?” Bot should understand: Order tracking inquiry
User: “I want to send this back” Bot should understand: Return request
3. Provide Escape Hatches
Always offer paths out:
- “Talk to a human”
- “Start over”
- “Something else”
- Clear menu/options
4. Handle Failure Gracefully
When the bot doesn’t understand:
Bad:
“I don’t understand. Please rephrase.”
Good:
“I’m not sure I understood. Did you mean:
- Track an order
- Return an item
- Something else”
Conversation Design
Opening Message
✓ Introduce the bot
✓ Set expectations
✓ Offer starting options
Example:
"Hi! I'm Alex, your support assistant.
I can help with:
• Order tracking
• Returns & exchanges
• Product information
What can I help you with?"
Follow-Up Questions
Ask one thing at a time:
Bad:
“What’s your order number, email, and what’s the issue?”
Good:
“I’d be happy to help! First, could you share your order number?”
Confirmation
Verify understanding:
"Just to confirm—you'd like to return order #12345 for a refund. Is that right?"
[Yes, proceed] [No, let me clarify]
Handoff to Human
Make it seamless:
"I'll connect you with a team member who can help further.
They'll have our conversation history, so you won't need to repeat yourself.
Typical wait time: 2 minutes."
Technical Best Practices
Response Time
| Action | Target |
|---|---|
| Acknowledge | < 1 second |
| Simple response | < 3 seconds |
| Complex query | < 5 seconds |
| Typing indicator | During processing |
Context Management
Remember conversation history:
User: "I want to return my order"
Bot: "I'd be happy to help with your return. What's your order number?"
User: "12345"
Bot: "Got it! I found order #12345 - the blue running shoes for $89.
What's the reason for the return?"
User: "Wrong size"
Bot: "No problem! Would you like to exchange for a different size,
or get a full refund?"
Error Handling
□ Rate limit exceeded → Friendly wait message
□ Service unavailable → Apologize + offer callback
□ Unknown intent → Offer options + human escalation
□ User frustration detected → Proactive human offer
Personality Guidelines
Do
- Be helpful and friendly
