Learn MoreMozCast tracks the daily "weather" patterns of the Google algorithm. While major algorithm updates get a lot of press, Google made over 3,000 changes to search in 2018. What we notice and name is barely the tip of the iceberg. MozCast was designed to help you spot those unconfirmed changes in the Google algorithm.
How Does MozCast work?
Every 24 hours, we track a hand-picked set of 10,000 keywords (across 20 industry categories and 5 major US cities) and analyze page one of Google organic results, comparing it to the previous day. The MozCast temperature reflects the degree of change in the day-over-day rankings, with an uneventful day being about 70°F. Put simply, the hotter the temperature, the more change we saw in Google rankings in the previous 24 hours.
How do I use MozCast?
MozCast has been running since 2012 over a controlled data set, giving us a rich history to explore and challenging how we think about Google search results. Ultimately, it helps answer the question: "Did Google change, or was it just me?" Our SERP feature tracking can also help you quickly spot shifts in the ever-evolving landscape of rich search features, including Featured Snippets, Local Packs, Top Stories, and much more.
