Google Merchant Center Descriptions, Product Highlights and Product Details

How to write Google Merchant Center product descriptions, highlights and details that help Google Shopping and AI Mode understand your products.

Why these fields matter now

Titles decide most of the searches you show for, but descriptions, highlights and details give Google the facts behind them. Google says product highlights and product details help shoppers find products on AI-driven surfaces such as AI Mode in Google Search, as well as in regular results.

Descriptions

  • Describe the product itself: what it is, what it is made of, how it fits or works and who it is for.
  • Put the most important facts first.
  • No promotional text, prices, shipping or store policies, and nothing that isn't on the product page.

Product highlights

  • Short, quick-to-scan points about the product's most important features.
  • At least 2 and up to 100, each up to 150 characters. Google recommends 4 to 6.
  • Describe only the product, not accessories, similar products or your business.

Product details

Product details are a specification table: an optional section name, an attribute name and a value, such as General, Material, 100% cotton. Up to 100 are allowed, each value up to 150 characters. Use them for facts not covered by other attributes, such as dimensions, care instructions or compatibility.

Stay factual

Every word should be true of the product and supported by your product page. Copying a supplier's text is common for dropshipping stores, and rewriting it in your own words from the real product facts makes listings clearer and more distinct.

Can product highlights include my returns policy?
