Answer Engine

Grounding
The practice of connecting AI responses to verified, real-world information sources to improve accuracy.
JSON-LD
A structured data format used to provide machine-readable information about content. Essential for AEO schema markup.
Knowledge Graph
A database of interconnected entities and their attributes. Google's Knowledge Graph heavily influences Gemini responses.
Knowledge Panel
A box in Google Search displaying verified information about an entity. Having a Knowledge Panel significantly boosts AEO visibility.
LLM
Large Language Model. The AI technology underlying ChatGPT, Claude, Gemini, and other AI assistants.
Perplexity
An AI search engine that uses real-time web search to answer queries, displaying source citations in its responses.
Prompt
A query or question submitted to an AI assistant. In AEO, tracking which prompts mention your brand is key.
Prompt Visibility
Whether your brand appears in AI responses for specific prompts or query types.
Real-Time Search
AI systems (like Perplexity) that search the web live to answer queries, unlike systems that rely solely on training data.
Schema Markup
Structured data added to websites to help search engines and AI understand content context. Essential for AEO.
SEO
Search Engine Optimization. Traditional practice of optimizing for Google Search rankings. Related but distinct from AEO.

Training Data
The corpus of information used to train an LLM. Content in training data influences AI responses.
