    Definition

    Definition Blocks are short, structured explanations that define a term, product attribute, material, method, or concept in plain language.

    Why It Matters

    Definitions help agents map user language to product data and reduce ambiguity in category and guide content.

    How AI Uses It

    AI extracts definitions for entity understanding, query expansion, glossary answers, and contextual recommendations.

    Commerce Example

    A bedding site defines GSM as fabric weight in grams per square meter and explains how it affects towel plushness and drying speed.

    Copy/Paste Prompts

    Replace the bracketed placeholders and run these prompts against your priority product lines, categories, or brand pages.
