Hey DEV community!
Wanted to share something I've been working on. I built Cirv Box, a free WordPress plugin that auto-generates Schema.org structured data (JSON-LD) for your site.
The Problem I Solved
I was frustrated that:
- Most schema plugins are bloated with features I don't need
- The good ones cost $67-199/year
- Manual schema is tedious and error-prone
- Non-technical site owners have no idea how to implement it
What It Does
Cirv Box automatically adds schema markup to:
- Blog posts → Article schema
- WooCommerce products → Product schema with prices, reviews, stock status
- FAQ pages → FAQ schema (detects Q&A patterns automatically)
- Tutorial content → HowTo schema with step detection
- Business info → Organization schema on homepage
- Navigation → Breadcrumb schema for all pages
Everything runs automatically. No coding required. Just toggle on what you need.
Tech Stack
- Pure PHP (WordPress requirements)
- Zero external dependencies
- JSON-LD output (Google's preferred format)
- 24-hour transient caching for performance
- Multisite compatible
- ~2,400 lines of code
What I Learned Building This
- WordPress.org review is brutal - Took 6 rounds of compliance fixes (escaping, sanitization, prefix requirements)
- Schema validation is tricky - Empty fields break Google's validator, had to add conditional logic everywhere
- The 90/10 rule is real - 90% of the work was edge cases and polish
Results
The plugin is now live on WordPress.org:

What's Next
Planning to add:
- Local Business schema (for physical locations)
- Video schema (for embedded content)
- Event schema (for webinars/events)
Would love feedback from anyone running WordPress sites. What schema types would be most useful to add next?
