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.
