Websitescanner Custom Schema is a free WordPress plugin designed to enhance SEO by allowing users to add custom JSON-LD schema markup directly within the post and page editor. This tool simplifies the integration of structured data, enabling website owners to implement their own schema without needing to write any script tags. The plugin also features a validation tool to ensure that the JSON-LD is formatted correctly, making it user-friendly for those looking to optimize their site's search engine visibility.

The plugin is particularly useful when combined with other SEO tools like Yoast SEO. Users can easily disable the default schema generated by such plugins or themes and replace it with their custom schema on specific pages or posts. This flexibility allows for more precise control over how content is presented to search engines, ultimately improving the chances of better search rankings and visibility.
