The anti-spam department is a specialized unit within large Internet companies, especially in the context of search engines such as Google, which is tasked with maintaining the quality and fairness of their search results. Employees in this department develop, test, and implement complex algorithmic and manual control methods.
Their main function is to identify and combat deceptive techniques (so-called “spam”) that are used by some websites to artificially increase their ranking factors and, ultimately, increase traffic and monetization. These techniques can include creating unnatural links, cloning content, or hiding text.
When a site is found to be violating quality guidelines, the department can apply sanctions (penalties) that lead to a significant decrease in its ranking or even its complete removal from the search engine index. In this way, the department provides more relevant and useful results for end users by punishing unfair practices.
