Bing Now Supports data-nosnippet for Search & AI Results

Bing has introduced support for the data-nosnippet HTML attribute, offering website owners enhanced control over how their content appears in search snippets and AI-generated responses. This development allows publishers to exclude specific sections of a webpage from appearing in Bing Search results and Copilot answers, while the page itself remains fully indexed and eligible to rank.

The data-nosnippet attribute can be applied to any HTML element, ensuring that designated content stays hidden from previews. When Bing’s crawler processes a site, it still discovers the marked sections but deliberately omits them from snippet text and AI summaries. This gives webmasters a powerful tool for managing what users see before clicking through.

Common applications for this feature include keeping paywalled or premium material out of previews, reducing the visibility of user comments in AI responses, and hiding legal disclaimers or cookie notices. It also helps suppress outdated promotions, exclude affiliate disclaimers from neutral previews, and minimize noise from A/B testing by hiding variant content during experiments. The goal is to emphasize high-value content while keeping sensitive or secondary information accessible only after the click.

Implementation requires minimal effort. Simply add the attribute to relevant elements:

<div data-nosnippet="">
<h3>Subscriber Content</h3>
<p>This section will not appear in Bing Search or Copilot answers.</p>
</div>

After implementation, changes can be verified using Bing Webmaster Tools’ URL inspection feature. Depending on crawl frequency, updates might appear almost immediately or take up to a week to reflect in search results.

This new attribute complements existing page-level directives rather than replacing them. While noindex removes entire pages from search indexes and nosnippet blocks all text and thumbnails from previews, data-nosnippet provides surgical precision by targeting only specified sections. Other directives like max-snippet, max-image-preview, and max-video-preview control preview length or size, but data-nosnippet focuses on content exclusion with granular control.

For subscription-based websites, this means subscriber-only content can remain hidden from previews without affecting the page’s search visibility. Sites featuring user-generated content can prevent comments or reviews from appearing in AI summaries while keeping their core editorial material fully visible. Essentially, it enables websites to maintain ranking potential while carefully curating what appears in search previews.

The feature is currently available for immediate use. Website operators should consider implementing it on pages where preview control is most critical, then monitor the results through Bing Webmaster Tools to ensure proper functionality.
