Bing has confirmed that xRank, the search service available on the Bing homepage, has been shut down. Attempts to use xRank will bring users back to the Bing home page.
xRank was released back in 2007 as Bing's answer to "Google Trends." xRank was billed as a "cultural snapshot of who's hot and who's not." It used search information to track the most popular queries on Bing. Results were posted in different categories.
This may come as bad news to users who relied on these trends to dictate SEO strategies and content development. Websites focusing on recent celebrity news were known to rely heavily on xRank as a way of seeing which celebs people were actually searching to find more information on.
