How often do search engines implement algorithm changes?

[Min George]

Search engines and even social media platforms implement algorithm changes in ranking of contents.

From your experience, how long before an algorithm change is implemented in a search engine. Just the average duration.

I honestly don't know how often they do it, but I deduce that it must be quite frequently because you never notice they're doing it, but you do notice it when you use it.

Last year, Google implemented three major changes to the entire ranking of sites. It is always around 4 core changes every year.
