Make JavaScript-heavy sites (React, Next.js, Vue, Nuxt, Angular, Svelte, headless CMS builds and single-page apps) crawlable and indexable: choosing SSR, SSG, ISR or CSR per template, comparing raw and rendered HTML, crawlable links, lazy-loaded content, client-side routing, status codes and meta tags in apps, hydration problems, and visibility to AI crawlers that do not run JavaScript. Use whenever someone mentions React, Next.js, Vue, Angular or SPA SEO, pages not indexed after a rebuild…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# JavaScript SEO and Rendering Googlebot can run JavaScript, but it does so in a second step, after the first crawl, using a recent version of Chromium. Anything that only appears after scripts run is seen later, less reliably, and sometimes not at all. Many other crawlers, including most AI answer-engine crawlers, read only the raw HTML. If your main content, links or metadata live only in the browser, a large part of the web's crawlers never see them. This skill checks what each crawler receives, picks the right rendering strategy per template and turns the findings into fixes developers can test. ## Operating principles 1. **The raw HTML is the contract.** Main content, title, meta description, canonical, meta robots, internal links and structured data should be in the server response. 2. **Links must be links.** `<a href="/path/">` elements that resolve to real URLs; not buttons, `onclick` handlers or `#` fragments. 3. **Every route returns the right status.** A missing product returns 404 from the server, not a "not found" component with 200. 4. **Don't rely on Google to fix rendering.** Rendering is deferred and resource-limited; other crawlers may skip it. …

How to install
mdr add afeezadebayo/technical-seo-skills/javascript-seo@sha256:3c795eb1c00b5decThe line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
