What is Semantic Chunking?
Semantic Chunking is the practice of organizing content into small, meaningful, and self-contained sections that each focus on a specific user intent or question.
This makes it easier for both readers and AI-powered tools (like ChatGPT, Google’s Search Generative Experience, or Perplexity) to understand, retrieve, and reuse the information.
Why Semantic Chunking Matters
✅ Improves Answer Engine Optimization (AEO): AI tools extract and repackage content from clearly defined chunks.
✅ Enhances readability: Humans and machines scan more effectively when information is grouped logically.
✅ Boosts semantic retrieval: Well-structured chunks align with how Large Language Models (LLMs) understand and serve answers.
How It Works (Simple Example):
Instead of writing one long paragraph about “email marketing,” you break it down like this:
❌ Bad (Unchunked)
Email marketing is a powerful tool. It helps with nurturing leads, increasing conversions, and driving retention. You should use segmentation, automation, and personalization.
✅ Good (Semantically Chunked)
