WP SEO Structured Data Schema is a plugin built specifically for structured data, rather than a schema feature bolted onto a broader SEO plugin. That focus shows in the level of control it gives you. You can add schema globally across a post type, or you can go in at the individual post level and add or override schema for that specific page. For sites where content varies significantly from post to post, that granularity is exactly what you need.
The plugin supports JSON-LD injection and covers the key schema types you’re likely to need, including Article, Local Business, Review, and FAQ. The free version provides a solid base, and the paid tiers unlock additional schema types and more advanced automation features. I find the manual override capability particularly useful on client sites where certain cornerstone pages need bespoke schema that doesn’t fit the standard template rules.
The interface is functional rather than beautiful. It gets the job done, but compared to Schema Pro’s mapping system it feels less polished. The documentation could also be clearer in places, particularly around the automatic injection settings and how they interact with schema from other plugins. If you’re running a broader SEO plugin like Yoast or Rank Math, you’ll want to check for conflicts before activating both simultaneously. That said, the plugin is actively maintained and the free tier is genuinely usable, which puts it ahead of several abandoned alternatives in the WordPress repository.
