: BingPreview user agent I'm getting several invalid requests from a "BingPreview" user agent. The complete user agent header is: Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/534+ (KHTML, like Gecko)

I realize that this is an old post but after researching this I came upon an article explaining the purpose of this user agent.

In this article they explain that this is a user agent string used to fetch images in real time when being accessed through the Bing app. Meaning as you scroll through pictures within this app you may end up clicking on one to bring up a full screen view. When you do this the user agent string is used to make a request to your site to get the latest version of the image.

They may be testing full page previews in search results similar to Google's. When you preview your page in Google you get a hit from one of their IP's. Bing right now just has a snippet of information and may be working on a full preview of the web page
