Schema & Structured Data for WP lets editors pick a schema type per post type (Article, Product, Recipe, Event, Course, FAQ, HowTo, LocalBusiness, and so on) and override per-post values via a meta box. Choices land in wp_postmeta under keys like _saswp_post_specific_schema_enabled, saswp_modify_this_schema, the per-field override keys, and a global JSON blob in wp_options with the schema rules. The admin lists schemas in a table, one row per rule, and surfaces each post's schema only inside the post editor.

That works for editing one schema. It does not work for the question every SEO lead asks each quarter: how much of the corpus actually carries valid schema, which post type is uncovered, and how that coverage is trending. SleekView Charts reads wp_postmeta joined to wp_posts and the global rules option, then renders four chart cards on top of it. A Number for posts without any schema enabled. A Pie split by chosen schema type. A Bar of schema coverage per post type. An Area of schema updates per week.

The plugin still owns the JSON-LD output, the Knowledge Graph settings, and the Google Rich Result rules. SleekView only reads the saved keys and the rules option, so editors keep using the same meta box while the SEO team finally has a single screen for corpus-wide coverage.

Schema & Structured Data for WP records the data that drives a structured-data audit, but the admin shows one rule at a time and the meta box shows one post at a time. Neither surface answers "how much of the corpus has schema attached" or "which post type is uncovered" without an export. SleekView Charts reads the same saswp postmeta, joins to wp_posts and the global rules option, and renders four cards that answer those questions in one glance.

The data is already correct because the plugin wrote it. Charts just gives the team a dashboard to look at it. Search Console flags missing markup weeks after the fact.

A live coverage dashboard catches the gap on the day a new post type lands.
