What Is BingPreview?
BingPreview generates page snapshots and previews for Bing, creating visual representations of web pages for search results using both desktop and mobile variants. You can see how often BingPreview visits your website by setting up Dark Visitors Agent Analytics.
Agent Type
Expected Behavior
Fetchers retrieve metadata from web pages to generate link previews in social media platforms, messaging apps, and content aggregators. They're triggered on-demand when users share or post links, fetching information like titles, descriptions, and thumbnail images. Traffic is unpredictable and correlates with how often your content is shared. Viral content may trigger thousands of fetcher requests in a short period. Fetchers typically access only the shared URL rather than crawling your site.

Should I Block BingPreview?
No. Blocking fetchers prevents link previews from appearing when your content is shared on social media, messaging apps, and other platforms. This significantly reduces click-through rates and social engagement. Link previews are crucial for content distribution.
How Do I Block BingPreview?
If you want to, you can block or limit BingPreview's access by configuring user agent token rules in your robots.txt file. The best way to do this is using Automatic Robots.txt, which blocks all agents of this type and updates continuously as new agents are released. While the vast majority of agents operated by reputable companies honor these robots.txt directives, bad actors may choose to ignore them entirely. In that case, you'll need to implement alternative blocking methods such as firewall rules or server-level restrictions. You can verify whether BingPreview is respecting your rules by setting up Agent Analytics to monitor its visits to your website.
Will Blocking BingPreview Hurt My SEO?
Blocking fetchers will hurt your social SEO and content distribution. Link previews significantly improve click-through rates from social media, messaging apps, and other platforms. Without previews, your content appears less engaging when shared, reducing social signals that can indirectly benefit search rankings.
Does BingPreview Access Private Content?
Fetchers only access the specific URLs that users share or embed, without credentials or authentication. They're designed to retrieve publicly accessible metadata and preview information. Fetchers don't crawl beyond the shared URL and can't access private content unless the shared link itself provides public access to otherwise private information.
How Can I Tell if BingPreview Is Visiting My Website?
Setting up Agent Analytics will give you realtime visibility into BingPreview visiting your website, along with hundreds of other AI agents, crawlers, and scrapers. This will also let you measure human traffic to your website coming from AI search and chat LLM platforms like ChatGPT, Perplexity, and Gemini.
Why Is BingPreview Visiting My Website?
BingPreview visited your site because someone shared one of your URLs on a social platform, messaging app, or another service that generates link previews. The fetcher was triggered when the link was posted to retrieve your page's title, description, and preview image.
How Can I Authenticate Visits From BingPreview?
Agent Analytics authenticates agent visits from many agents, letting you know whether each one was actually from that agent, or spoofed by a bad actor. This helps you identify suspicious traffic patterns and make informed decisions about blocking or allowing specific user agents.
