Site demotion is the intentional lowering or worsening of a website’s position in the search engine results page (SERP), either by a search engine algorithm or as a manual penalty. This term describes the state of reduced visibility that results from an identified violation of the Webmaster Guidelines.
Conceptually, demotion is a disciplinary or corrective mechanism. It serves as a sanction for websites that engage in black-hat SEO practices, such as keyword stuffing, poor link building (PBN), cloaking, or duplicate content.
Demotion is a signal of commercial risk. In the case of an algorithmic penalty, it requires a thorough audit and correction of the issues. In the case of a manual penalty, it requires the violation to be remedied and a reconsideration request to be submitted to the search engine.
