No-JavaScript Content Scanner
Detects whether your site is a near-empty SPA without JS that AI crawlers can't index or cite.
What it checks
This scanner detects whether your site is a single-page application (SPA) that arrives nearly empty when loaded without running JavaScript. It checks how much real content is available before the browser processes the code.
Why it matters
Many AI crawlers and search engines don't run JavaScript, so if your content only appears after loading it with JS, to them your page is blank and they can't index or cite it. This is very common on sites built with modern frameworks by vibe coders without realizing it.
How to fix it
Use server-side rendering (SSR) or static generation (SSG) so the HTML arrives with the main text and links already in place. Most modern frameworks offer this option; enabling it ensures both Google and AI see your real content.
