ChatGPT

ChatGPT (Bing + Broad Fanout) is OpenAI's AI Search platform using Bing's index with broad query fanout: prefers Wikipedia content.

ChatGPT is OpenAI's AI Search platform that uses Bing's index and applies broad query fanout. Citation source distribution: Wikipedia 47.9%, industry directories 25.2%, media 19%. This means earned media dominates over owned media.

Broad fanout means ChatGPT generates many sub-queries and searches diverse sources, giving sites that cover multiple sub-questions better visibility. To be visible in ChatGPT: ensure Bing indexation (not just Google), build presence in Wikipedia or industry directories, invest in earned media (PR, guest publications). ChatGPT often cites a brand's homepage when its Web Entity is consistent—that's why the 'API-able Brand' strategy (identical data across all platforms) is particularly important.

In practice, check your site's visibility in Bing Webmaster Tools: if you're not in Bing's index, you're invisible to ChatGPT. YouTube is gaining importance in ChatGPT (+121% citations year-over-year), so creating video content is worthwhile.
