SERP volatility index refers to the changes in Google and Bing SERP rankings and ranges from 1 to 10. On this scale, one is characterized by minimal changes in search engine rankings and ten corresponds to dramatic changes in Google search algorithms and major updates to search engine algorithms.
DataForSEO checks Google and Bing SERPs for a fixed list of keywords and measures the volatility of results’ changes daily. Each keyword in a set is assigned with a category, which allows us to estimate and display volatility across various product, service, and industry categories.
To calculate the SERP Volatility Index, we are continuously analysing search engine results pages and applying DataForSEO’s proprietary formula to provide the result.
