Recent drop in Bing SERPs


I am working on seven sites and their ranking was pretty consistent in Bing on almost all keywords for around three to four months but yesterday I found a significant drop in all of my sites ranking in Bing SERPs. As this effect is on all the sites that I am working so it could not be due to some bad link.

Is this because of any update in the algorithm and Was any one also facing it?



I am not seeing any major drop in other search engines but Bing is showing an extraordinary drop in results.

there might be broken links makes drops over all Search engines not only bing.
