Black hat SEO is a practice that goes against search engine guidelines, used to get a website to have a higher ranking in SERPs (search engine results page). These unethical tactics don't solve the search engine's purpose and often end up in a search engine penalty. Black hat techniques include keyword stuffing, cloaking, and using private link networks. Search engines, such as Google and Bing, make it very clear what types of practices go against their terms.
They are also quite clear as to the possible outcomes if you violate their guidelines. Using black hat SEO tactics can lead to your website being penalized (either algorithmically or with manual action), which means lower ranking positions and, most likely, a decrease in organic traffic. Duplicate content is one of the worst black hat techniques. This refers to the “copy and paste” content creation practice across domains and means that blocks of content copied from different sources exactly match each other or look very similar.
Search engines prefer unique content, so deliberately duplicated content across different domains is perceived as one of the worst black hat techniques. It is crucial to implement a canonical tag to indicate the original version of your article. Article spinning is another black hat technique that is becoming increasingly popular. This is higher-level plagiarism and involves the use of special software that takes the copied source and reformulates it for later use as a “new” and unique publication.
The modification efficiently reduces the risk of being detected by any plagiarism tool. Cloaking is another black hat technique that presents completely different content or URL to the user than to the search engine spider. In most cases, it serves people with irrelevant results and violates Google's webmaster guidelines. Keyword stuffing involves overusing the same keywords on a page to maximize its visibility and organic traffic.
