JS SEO Lab — Homepage
Pattern survival mapping across batch crawlers and on-demand LLM fetchers.
Current pattern: Late-loaded (IntersectionObserver)
What we measure
- Pattern survival per bot class. Which JS content patterns disappear in bot responses, and which survive.
- Batch vs on-demand split. GPTBot vs ChatGPT-User: same provider, different capabilities — measured per pattern.
- Bing rendering revisited. First systematic test of Bing's JS rendering since the 2019 Edge crawler note.
