When it comes to designing your knowledge base articles for AI retrieval, choosing between bulleted and numbered lists isn’t just a stylistic decision - it impacts how information is chunked, indexed, and ultimately, retrieved by Context Retrieval Systems.

Note: The following advice is based on research with chat-based models like OpenAI 4.0. We’ve noticed similar results with Chain of Thought Reasoning models such as Deepseek R1, though outcomes may vary.

Why List Format Matters
Smaller, well-structured content groups are a game changer for AI-driven search. Just as organizing Zendesk articles into neat, focused sections improves human navigation, it also refines how your AI pulls relevant data. Lists, whether bulleted or numbered, serve as visual cues that break down complex information into digestible parts.

Bulleted Lists: For Unordered, Quick References
Bulleted lists shine when you need to present items without implying a sequence. They’re ideal when:

• Highlighting key points: Think of them as quick-reference cards that help your AI focus on critical details without the distraction of order.

• Chunking information: They allow the AI to isolate and prioritize content segments, improving retrieval accuracy.

• Enhancing readability: For support articles where customers need a fast scan of solutions, bullets act like signposts pointing to essential tips.

You want AI to have more flexibility: Your AI will be able to make better decisions when interacting with bulleted lists, as it understands it can use a combination of different bullet points in the same response. By contrast, mixing steps (e.g., step 1 and step 4) from a numbered list is typically an unexpected outcome and lowers reasoning clarity.

For example:

• “Tips for faster troubleshooting,” 

• “Key system settings,” 

• “Common user errors.” 

AI can pick and choose from any tip without implying order.

Numbered Lists: When Order or Sequence is Key
Numbered lists, on the other hand, suggest a hierarchy or sequential process. They are best used when:

1. Outlining step-by-step procedures: For troubleshooting guides or setup instructions, numbered lists provide a clear path, making it easier for the AI to map procedural steps.

2. Ranking information: When details need to be prioritized or the sequence is crucial for understanding, numbers add structure and clarity.

3. Facilitating cross-references: In complex support articles, numbering steps can help the AI connect related procedures, ensuring that no step is overlooked.

For example:

1. Install software

2. Configure user permissions

3. Run diagnostic tests

AI sees these steps as a logical progression, reducing confusion about the proper order.

How AI Benefits from These Choices
A well-structured knowledge base improves the AI’s retrieval rate by establishing clear content boundaries. Here’s a quick breakdown:

For Bulleted Lists:

• AI retrieves more contextually grouped information

• Faster recognition of key points

• Reduced noise from non-sequential data

For Numbered Lists:

• AI follows the logical progression of steps

• Ensures correct order in problem-solving processes

• Enhanced ability to provide context-specific answers

List format matters. AI retrieval depends on structure, so choose wisely!
