Rank Risk Index
Google SERP Fluctuations
Rank Risk Index measures SERP fluctuations for 10,000+ domains and keywords that we monitor daily. It is one of the tools in our Google algorithm monitoring service.
We also log SERP structure changes and track Google SERP features to determine whether ranking fluctuations are potentially being caused by changes in the type or number of vertical search engine results (e.g., Images, News, Maps, etc.) that Google included in page one results.
More information can be found in our Google Algorithm Updates History.
