Google & Bing “Weather Report” Tool has quietly launched a SERPs Volatility Index, which aims to work like the MozCast tool to track search results fluctuations and help webmasters know if there was an algorithm update at Google and Bing.

While MozCast only tracks Google, tracks both Google and Bing. also shows a 30-day and 90-day volatility charge. It works a lot like the MozCast solution in that it tracks the top keywords for 1,000 popular websites on Google and Bing, adding up to tens of thousands of keywords being tracked. The tool is also updated daily.

Here are static screen captures of the SERPs Volatility Index as of today:

By the looks of it, and MozCast share the same interpretation of the Google fluctuations in the search results, for the most part.

Both the tools do show a change at Google over the weekend, which is what we reported this morning.
