Definition
What this term means
The process of anchoring AI outputs to verified, factual source material rather than allowing the model to generate responses purely from its parametric knowledge. Grounded AI responses include verifiable claims backed by cited sources, reducing the risk of hallucination and improving accuracy. Google's Gemini and Perplexity AI both use grounding extensively.
Why it matters
The business impact
AI platforms are increasingly prioritising grounded responses because they are more reliable and trustworthy. Brands that provide clear, verifiable, well-structured source content are more likely to be used as grounding references, earning citations and traffic. Content that is vague, unverifiable, or poorly sourced is less likely to be selected as a grounding source.
Used in context
How you might use this term
“A medical information provider structured their content with clear, sourced claims and author credentials. Perplexity and Gemini began using their pages as primary grounding sources for health-related queries, generating significant referral traffic from AI-powered search.”

RAG
An AI architecture that combines real-time information retrieval with language generation. Instead of relying solely on pre-trained knowledge, RAG systems search external sources, such as websites, databases, or knowledge bases, to find relevant information before composing their response. This is the technology behind AI search tools like Perplexity and Google's AI Overviews.
Hallucination
When an AI model generates information that sounds plausible but is factually incorrect, fabricated, or unsupported by its training data. Hallucinations can range from minor inaccuracies, such as attributing the wrong feature to your product, to entirely fabricated claims, such as inventing awards or customer testimonials that do not exist.
Model Citation
An instance where an AI model references, quotes, or links to a specific source when generating its response. Model citations can appear as inline references, linked source lists, or attributed quotes, and they represent the AI equivalent of earning a backlink in traditional SEO. Platforms like Perplexity and Google's AI Overviews prominently display citations.
