Alt text

A short text description of an image. Agents can't see pictures, so this is how they learn what a product photo shows. See alt text for AI agents.

Why it matters

Agents can't see your photos, so alt text is how they learn what a product looks like, which colour it comes in or what's in the box. Good alt text helps agents describe and compare your products accurately, and it's already expected for accessibility. Your content or merchandising team can usually add it in the tools they use for product pages.

More terms in understanding pages

• Raw HTML The page exactly as your server sends it, before any JavaScript runs.
• Server-side rendering (SSR) and static generation Ways of building pages so the content is already in the raw HTML, rather than added afterwards by JavaScript.
• Structured data (schema.org, JSON-LD) Machine-readable facts in your page code, such as a product's name, price and stock, written in the shared schema.org vocabulary, usually as JSON-LD.
• XML sitemap A file listing the pages you want found, so crawlers and agents don't depend on following links.
• Canonical URL The one address you name as the main version of a page that can be reached in several ways.
