Pattern survival mapping across batch crawlers and on-demand LLM fetchers.

Current pattern: JS-rendered links

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.

Methodology

This page is part of an open research experiment. Bot hits are logged to a public-ish tracker (anonymized IPs, hashed). Marker UUIDs aggregate visibility per cell over time. Full methodology and data at jsseo.dev.
