Google penalties are actions taken by the search engine to demote or remove websites from search results that violate their Webmaster Guidelines. These guidelines are a set of rules and best practices that help ensure a positive user experience and maintain the integrity of Google's search results.

As previously explained, there are two types of Google penalties. manual and algorithmic. A manual penalty occurs when a Google employee manually reviews your website and finds it does not comply with quality guidelines. An algorithmic penalty, on the other hand, is applied automatically by Google's algorithms.
