BingPreview — Bing page snapshot fetcher
BingPreview is a user agent associated with Bing's fetching of page snapshots and previews. It is part of Bing's crawling activity alongside Bingbot. Specific current behaviour is best confirmed in Bing Webmaster documentation, so this entry is marked partially verified.
What this means
BingPreview is a user agent that has been associated with Microsoft Bing fetching page snapshots and previews. It is part of Bing's broader crawling activity, which is led by Bingbot.
Because Bing's crawler details change over time, the precise current role of the BingPreview user agent should be confirmed in Bing Webmaster documentation rather than assumed. This entry is therefore marked partially verified.
How it relates to Bingbot
Bingbot is Bing's primary crawler for discovery and indexing. BingPreview has historically been a separate user agent tied to preview/snapshot fetching. Verification of Bing crawlers follows Microsoft's documented reverse-DNS method (resolving into search.msn.com) and published IP ranges, since user agents are spoofable.

How it appears in analytics and logs
BingPreview requests have historically related to Bing fetching page snapshots or previews for its results. They are bot traffic from Microsoft's search infrastructure, not human visits. Current scope is best confirmed against Bing's own documentation.
Diagnostic use case
Recognise BingPreview hits in logs as Bing snapshot/preview fetches rather than human visits, and treat them as part of Bing's crawling footprint.
What WebmasterID can help detect
WebmasterID classifies Bing crawling server-side as search-crawler activity and shows it separately from human traffic, so Bing-related fetches are visible without log parsing.
Common mistakes
- Treating BingPreview hits as human page views.
- Assuming exact current behaviour without checking Bing Webmaster documentation.
Privacy and accuracy notes
Identification uses only the user agent — no human identity is involved. WebmasterID records BingPreview as a bot event, separate from human analytics.

Bingbot is the crawler Microsoft Bing uses to discover and index web pages. It uses the bingbot robots.txt token and can be verified through Bing's reverse-DNS method and published IP ranges. Bing also powers results for other surfaces, so Bingbot coverage has reach beyond Bing.com.
