Schema Article JSON-LD adds the structured data that helps search engines understand your content and can unlock rich results. On every page it outputs WebSite and Organization schema, and on single posts it adds an Article entity with headline, author, dates and featured image, plus a BreadcrumbList. Everything is emitted as a single valid JSON-LD graph in the head — no settings to wrestle with, no external calls.

Will this give me rich results in Google?
It outputs valid, eligible structured data, which is a prerequisite for rich results. Google decides whether to show them based on many factors, but correct schema gives you the best chance.
Does it duplicate schema if I use another SEO plugin?
Possibly. If your SEO plugin already outputs Article or WebSite schema, run only one to avoid duplicate entities. Disable the other plugin's schema or use this on sites without one.
Can I add my logo to the Organization schema?
Yes — edit the Organization array in the code and add a logo property pointing to your image URL. The code is plain, commented PHP.
Does it support pages and custom post types?
It targets posts for the Article entity by default. You can extend the is_singular() check to include pages or custom post types.
