What is Black Hat SEO? Techniques and Strategies

Black Hat SEO is a term used to distinguish correct SEO techniques from irregular techniques that take advantage of loopholes in search engine rules (or directly break them) to achieve quick results in search engine rankings. They are persecuted techniques and when it is verified that they have been used, they can entail severe penalties for the web pages involved.

These techniques promise quick and effortless results. In the short term, they can be very attractive in the eyes of the most inexperienced and less scrupulous users, but the risk of penalties is too high. It is honestly not worth spending money and resources to climb into positions that, in the end, will reverse damage to the company’s reputation and associated economic losses.

As with any dark practice, in any sphere of life, it is attractive. Appearing high in search results is vital to growing a business, but there is a right way and a wrong way to optimize your content for search engines.

Black Hat SEO is the wrong way. Playing with search engine algorithms instead of solving something for the user is a mistake. Instead of earning the right to rank high on search engine results pages, Black Hat SEO uses unethical tactics (some more than others, it must be said). Which are the best known and used?

Black Hat SEO: main techniques

In general, these are the main Black Hat SEO strategies that have been put into practice over the years. Many of them have even evolved and resulted in incomplete content (do you hear those articles that ask a question in the headline that is never answered?), of little value and practically filler.


Harry Potter’s cloak made him invisible to the eyes of others. In the field of SEO, this layer, or cloak, allows us to define the cloaking technique: we deceive the search engine by hiding the real web page that it has indexed and we deceive the user by showing another page or content. With this technique, an extraordinarily optimized page for search engines is proposed and, at the moment the user clicks on it, he discovers a page that is different from the original and that is not indexed in the search engine. Spam websites often do this to prevent web browser bots from discovering the spam content they offer to users.

Hide content

Hiding anything from a search engine is a bad idea. Using these content-hiding techniques, texts are usually written with the same color as the background of the page. The user does not read this content, but the search engine does track and index it. This technique can be combined with another one on this list, keyword stuffing.

Keyword stuffing

It is also known as the “over-optimization” of the keyword in content. The frequency with which we use keywords in content is an indicator, for most search engines, of the main topic that content is about. The erroneous belief is to think that if we repeat it more and more, we will position it better. This is not the case, in fact, since there are many other factors that are combined and analyzed in the process. The reality is that the keyword must always respond to the needs of the users and provide value.


Far removed from the sports practice with which it shares its name, this technique consists of generating several texts that are identical in content, but varying expressions, using synonyms and other issues, so that the web has more content designed to position. Again, the contribution of value for the user is nil and, in addition, search engines are getting better at detecting these abuses (and taking action).

Trading links

This technique was used massively at the beginning of the 2000s, and it consisted, simply, in buying links to your website: the owner paid other people certain amounts of money so that they placed links to his website and, in this way, way, said site saw its authority grow. Of course, this is a Black Hat practice and is subject to penalty. The links must be achieved organically and, in addition, it turns out that this is the best way to achieve real and beneficial results for both parties.

Black Hat SEO techniques are essentially a shortcut used by content creators who are in a hurry to get results and don’t care as much about the quality of their content, let alone their users.


In the realm of Search Engine Optimization (SEO), Black Hat SEO refers to the use of aggressive, unethical techniques and strategies aimed at manipulating search engines into ranking a website higher. These tactics typically do not consider the human audience or offer them genuine value. Common Black Hat SEO techniques include keyword stuffing, cloaking, using private link networks, doorway pages, and hidden text.

While these tactics might seem appealing for their promise of quick results, they come with significant risks. Search engines have become increasingly sophisticated at detecting Black Hat SEO. Violations of their guidelines, such as those involving Black Hat techniques, can lead to severe penalties, including a drop in rankings or even a complete de-indexing of a website.

Ultimately, while Black Hat SEO may offer short-term gains, the potential long-term damage to a site’s reputation and visibility makes these strategies a poor choice. Instead, focusing on White Hat SEO strategies those that align with search engine guidelines and prioritize providing real value to human users is a more sustainable and ethical approach to improving a website’s ranking and visibility. Therefore, it’s always advisable to use ethical, user-focused strategies that enhance the value of your content, improve user experience, and build a strong, sustainable online presence.
