MozCast Shows Huge Google Update But SEOs Don't Agree
Yesterday, MozCast, Moz's Google ranking volatility tool, reported the highest level of change in Google's search results in the history of MozCast. 113 degrees hot. Typically, on a normal day it will be in the high 60s or low 70s.

Why the huge temperature? The other tools such as SERPs.com and SERP Metrics reported normal days for Tuesday. And more importantly, I didn't see any chatter in the SEO forums that would signal a Google search algorithm or ranking update.

What set off MozCast? Dr. Pete explained what it might have been, giving a detailed look at the data but saying, he needs more time to give a definitive answer and even then, he might not know for sure.
One thing is for sure, I am 99% certain there was no major ranking change yesterday. The forums and level of discussion in those forums did not spike at all. In fact, it seemed like an incredibly slow day over the past 48 hours.
