This tab acts as a safeguard. It scans your site for other common SEO plugins (like Yoast, Rank Math, etc.) that also output schema to prevent a common issue: duplicate schema, which can confuse search engines.
If a conflict is detected, the plugin will take two steps:
First, it will warn you directly in this tab.
Second, it will provide clear instructions and code snippets on how to safely disable the schema feature in the other plugin.
