A simple, powerful plugin to add custom schema markup to WordPress posts & pages, helping search engines better understand your site's content.

Example of schema applied to a post
BBH Custom Schema gives you full control over your website’s structured data — without the limitations of traditional SEO plugins.
Most SEO plugins automatically generate schema, but they often restrict customization and can create duplicate or conflicting markup. This makes it difficult to control how search engines interpret your content.
BBH Custom Schema solves this by letting you manually add and manage JSON-LD schema on any post or page. You decide exactly what structured data is output — no restrictions, no overrides, no hidden logic.
Perfect for developers, SEO professionals, and advanced users who need precise, flexible control over their schema implementation.
Note: This plugin does not generate schema automatically. You must provide valid JSON-LD format.
Note: Validation only checks JSON format validity.
