About SEO Render Inspector

SEO Render Inspector compares a page's raw HTML (what the server returns, before JavaScript) with its JavaScript-rendered DOM, and tells you — element by element — what is server-side, injected by JavaScript, or removed/truncated by JavaScript. It checks: meta tags, textual content (with the exact text injected or removed by JS, shown in red), structured data (JSON-LD & microdata), canonical, hreflang, internal links, indexability (HTTP status, X-Robots-Tag, meta robots) and user-agent cloaking (your browser vs Googlebot). Why it matters: search engines render JavaScript, but most AI assistants (ChatGPT, Claude, Perplexity) and their crawlers fetch the raw HTML and do NOT run JavaScript — so anything only injected by JS is invisible to them. A clean, traffic-light report shows exactly where you stand. All analysis runs locally in your browser. No data is collected or transmitted.
