Japanese SEO-focused JSON-LD manager with automatic duplicate control.

== Description ==

ASMKC Schema is a structured data (JSON-LD) management plugin designed specifically for website operators in Japan.
It fully supports "Japanese business customs" and "Japanese address formats," which are often difficult to configure with international plugins. This plugin strongly supports display in Google Search's "Knowledge Panel" and "Rich Results."

The key feature is the **"Automatic Duplicate Control (Smart Control)"**.
It detects simple structured data automatically output by WordPress themes (Cocoon, SWELL, SANGO, etc.) or SEO plugins (All in One SEO, Yoast SEO, etc.).
It prevents duplicate errors while allowing ASMKC to output more detailed data with high E-E-A-T (Experience, Expertise, Authoritativeness, and Trustworthiness).
