BreadcrumbList
Also known as: BreadcrumbList schema / パンくずリスト構造化データ
A Schema.org type for breadcrumb navigation. Implemented via JSON-LD, it surfaces site hierarchy in Google search results, improving click-through rates and helping search engines understand site structure.
Overview
BreadcrumbList is an array of ListItem entries, each specifying position, name, and item (URL). When implemented, Google replaces the plain URL in search results with a breadcrumb trail, making site hierarchy immediately clear to users.
SEO Benefits and Implementation
BreadcrumbList strengthens internal link signals and helps search engines accurately map site hierarchy. The best practice in Next.js is to dynamically generate breadcrumb JSON-LD in layout components for each page.
