“Minusinsk” is the name of a significant algorithmic update of the Yandex search engine, introduced in 2015. This algorithm is a disciplinary mechanism designed to combat black-hat SEO practices in the field of link building, specifically the mass and manipulative purchase of SEO links to improve rankings.
Functionally, “Minusinsk” works as an anti-spam filter that analyzes the link profile of websites for unregulated or unnatural patterns of link acquisition. When a site is identified as violating these rules, the algorithm imposes a corrective penalty, which is expressed in a significant decrease in positions in search results. This is not just a temporary hesitation, but a targeted sanction for violating the main quality guidelines of the search engine.
In a broader sense, “Minusinsk” is an example of consolidating the algorithmic focus on organic authority. It demonstrates the principle that long-term ranking cannot be achieved by artificially injecting “weight” (PageRank), but requires naturally earned trust and recommendations from other quality resources that actually serve as a signal of authority in the given field.
