Auto-detection
Schema types picked automatically from post type, taxonomy and content patterns. WooCommerce products, recipes, events and FAQ blocks are recognised on activation — no mapping screen, no config wizard.
Schema markup, finally unbloated.
Valid JSON-LD for every post, product, FAQ and breadcrumb. Generated from the data WordPress already has. No setup wizard, no admin pop-ups begging for a five-star review, no 800KB JavaScript bundle parked in your footer.

What it does,
and what it doesn't.
Four things, done well. Cirv Box is not an SEO suite. It handles structured data and then gets out of the way. Pair it with Yoast, RankMath, Slim SEO — whatever you already use for meta tags and sitemaps.
Visual editor
Override any schema field from a panel inside the post sidebar. No code, no shortcodes, no nested-array PHP filter hunts. The right column previews the JSON-LD live as you type.
Multilingual
Works with WPML, Polylang and TranslatePress on install. Per-language schema with correct inLanguage and isPartOf wiring. Tested on a 7-language client site in March — zero plugin gymnastics required.
Audit reports
One-click PDF a non-technical client (or their compliance auditor) can actually read. Output passes Google Rich Results, the schema.org validator and Yandex Webmaster on every test we've thrown at it.
How it compares.
Real numbers, measured in April 2026. Bundle sizes from each plugin's own listed download. Feature coverage tested on identical WP 6.6 + Twenty Twenty-Four installs. No vapourware columns.

Questions.
The four we hear most. If yours isn't on the list, email hello@cirvgreen.com — an actual human (usually Nicholas) replies inside one working day.
Is it really free?
Yes. The WordPress.org version ships all 32 schema types and full auto-detection. No locked types, no scary "Pro" modals in your admin. The money comes from agencies and multilingual sites that pay for the visual editor and white-label audit PDFs.
Does it conflict with Yoast or RankMath?
No. On activation, Cirv Box detects other schema plugins and offers two options: switch off their structured-data output, or run alongside and deduplicate @id references. Most users disable the other plugin's schema and keep it around for sitemaps and meta tags.
Can I use it without writing code?
Yes. The free version needs zero configuration: install, activate, done. The Pro visual editor adds a sidebar panel to every post and product, so you can override any schema field without touching PHP, filters or shortcodes.
How do I migrate from another schema plugin?
Cirv Box ships a one-click importer for Yoast, RankMath, Schema Pro, SchemaPress and WP SEO Structured Data. Custom field mappings carry across. The migration is non-destructive: your old plugin's data stays put until you uninstall it, so rollback takes one click if anything looks off.
