On "How topical authority spreads (and where it doesn’t) in ChatGPT [Study]"

Topical authority as a concept starts collapsing the moment you test it against how LLMs actually work — these models don't care about your site's thematic coherence the way Google's algorithms do, so expecting spillover from one topic cluster to another misses the fundamental difference between ranking in search and performing well in an AI system that treats each query independently. The practical takeaway is obvious: stop designing content architecture around topical authority as a hedge for AI visibility, because ChatGPT doesn't reward domain consolidation the way search engines do, and chasing both strategies at once will only dilute your focus.
