Summary
If you're running a JavaScript documentation site and care about organic traffic, this skill systematically audits your concept pages for search visibility. It walks through keyword identification (targeting patterns like "what is X in JavaScript" and "how does X work"), on-page SEO elements, featured snippet optimization, and internal linking. The methodology is structured around the 33 JavaScript Concepts project, so it comes with pre-built keyword clusters for topics like closures, the event loop, and async/await. It's designed for pre-publish checks or when you're trying to figure out why a page isn't ranking. Practical if you treat documentation as a growth channel.
