Retrieval Augmented Generation (RAG)
Retrieval Augmented Generation (RAG) is an AI technique that retrieves real-time web content before generating responses, powering citation-based platforms like Perplexity.
Full Definition
Retrieval Augmented Generation (RAG) is an AI technique that combines the generative capabilities of large language models with real-time information retrieval. Instead of relying solely on training data, RAG-enabled AI systems search for relevant current information before generating responses.
How RAG Works:
- Query Analysis: AI interprets the user's question
- Retrieval: System searches indexed documents or the web
- Context Building: Relevant content is gathered and ranked
- Generation: LLM generates response using retrieved context
- Citation: Source attribution may be included
RAG in Popular AI Systems:
- Perplexity: Always retrieves current web content
- ChatGPT with Browse: Optional web browsing capability
- Google AI Overviews: Combines LLM with Search index
- Microsoft Copilot: Integrates Bing search results
Why RAG Matters for GEO:
- Your content can be retrieved and cited even if not in training data
- Fresh content has equal opportunity to be discovered
- Proper technical optimization enables retrieval
- Structured content is easier to extract and cite
Optimizing for RAG:
- Ensure AI crawlers can access your content
- Use clear, structured formatting
- Include direct answers to common questions
- Maintain accurate, up-to-date information
- Implement proper schema markup
