Shortly after the MozCast Tool for weather reports on Google, SERPs.com has introduced a SERPs Volatility Index to keep track of any fluctuations that come in search results. The tool will inform webmasters of any algorithmic rollouts made by both the search engines: Google and Bing. MozCast tracks just Google whereas with SERPs you get to keep an eye on both Google and Bing.
SERPs tool is updated daily and it keeps track of the leading keywords for a thousand sites on both the search engines. The Volatility Index tracks volatility changes for a 30-day as well as a 90-day period. What do you think of this tool? Do share your views.
