Context
Microsoft Bing announced support for data-nosnippet to exclude marked HTML sections from search snippets and AI-generated answer previews while leaving pages indexed and ranking eligible.
What changed
Bing added HTML section-level preview exclusion for traditional snippets and Bing-powered AI answers.
Why it matters
Publishers can limit which page sections appear in AI answers without excluding entire pages from indexing.
Visibility OS interpretation
Visibility OS interpretation: AI distribution governance distinguishes indexing, ranking eligibility, and excerpt display; this announcement documents that separation for Bing.
What remains uncertain
How consistently is the control honored across Copilot surfaces and partner integrations? What effect does it have on citations?
