next-seo is a search engine optimization toolkit and component library for Next.js. It provides a set of React components and utilities for managing page titles, descriptions, and social media tags to improve how web pages are indexed and displayed.
The project functions as a structured data manager and JSON-LD schema generator. It transforms entity data into standardized schema properties for articles, products, and organizations, enabling the implementation of rich snippets in search engine results.
The toolkit covers a broad range of metadata management, including business identity mapping, the creation of structured data for how-to guides, and the automation of schema type assignments.
