1. The Mechanics of Chunk Boundaries in Vector DBs
RAG systems slice web pages into fixed token chunks (e.g., 512 tokens with 50-token overlap). If a paragraph references 'this software' without naming the entity, the chunk loses context when evaluated in isolation.
2. Designing Self-Contained Section Loops
Every H2 section should act like a mini-article: state the entity name, define the core concept, provide proof, and summarize key takeaways.
// Structure of an Atomic Chunk [H2 Subheading with Full Entity Name] └─ [Definition Sentence] └─ [Empirical Proof / Metric] └─ [Actionable Takeaway]
3. Checklist for Atomic Section Design
- Repeat core entity names: Avoid using ambiguous pronouns at the start of sections.
- Keep section length under 400 words: Matches standard RAG chunk sizes.
- Include unique H2/H3 subheadings: Ensure subheadings reflect the specific sub-intent.

Understand with Google AI →Practical Exercise & Observation
Audit 3 section headings on your site. Rewrite them so that each section contains a self-contained entity definition that makes complete sense if read out of context.
Student Outcome
You can structure web pages into atomic section chunks that maintain complete semantic context inside vector retrieval windows.
