434 Days Later: ChatGPT and Claude Still Can't Render JavaScript Content
gaganghotra_ · x · 2026-10-20
SEO practitioner Glenn Gabe retested AI search platforms 434 days after his original August 2025 experiment and found ChatGPT, Claude, and Perplexity still cannot read content rendered via JavaScript.
- The chatbots explicitly admit JS rendering blocks them from seeing page content.
- Gemini and Copilot handled JS content fine in both rounds, since they leverage Google/Bing's rendering infrastructure; Google's own Generative AI optimization guide confirms it processes JavaScript if not blocked.
- Advice for site owners stands: don't rely on JS-based rendering for core content if you want AI search visibility—serve it in server-side HTML and test.
