Open-source builds that already do this
Every project below is open source and already does this job today. Fork one, self-host it, or take the parts you need - the build prompt further down assumes an empty file, and this is the shortcut past that. Licences differ; check the one on each card before you ship. All Yoast SEO Premium alternatives, with the arithmetic →

What we assumed
The verdict above measures whether you could build it. This one is only about money.
Runnable build prompt
Build a WordPress plugin (PHP 8+, WP 6+, Gutenberg) that provides in-editor real-time SEO and readability checks, generates AI-powered meta title and meta description using OpenAI-compatible API, and injects basic JSON-LD schema. In-scope: content parsing, SEO/readability rules engine, admin UI in Gutenberg, AI integration (configurable API key), saving meta to post meta, and unit/integration tests. Out of scope: a redirect manager, full WooCommerce catalog optimizations, multi-site licensing UI. Require robust error handling for API failures, rate limits, and automated tests covering parsing, checks, and AI call mocking.

The base comes from the verdict. Everything under it is a check that either happened or did not, and each one is a fact frozen in this record rather than a judgement made at render time - so the same evidence always produces the same number.
