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
• Use conversational language
• Show empathy for problems
• Be concise

Don’t

• Be overly casual/jokey
• Use jargon
• Be robotic
• Apologize excessively

Example Tone

Empathetic: "I understand how frustrating that must be."
Helpful: "Here's what I can do to fix this..."
Clear: "Your refund of $89 will appear in 3-5 business days."

Measuring Success

Key Metrics

Metric	Target
Resolution rate	> 70%
