Do better product attributes improve visibility outside my own website?

Yes. Rich, structured product attributes can improve how products are understood by search engines, marketplaces, shopping feeds and AI systems, provided those channels can access the data. Attributes such as material, colour, compatibility, dimensions and product type give systems more explicit signals for matching products to detailed queries. Better attributes do not guarantee visibility on their own, but they reduce ambiguity. The strongest approach combines structured product data with accurate content, valid feeds and crawlable storefront information.
