Top 5 Black Hat SEO Techniques You Should Avoid in 2021

Ten years ago, many mistakenly believed that SEO was a fraudulent marketing strategy centered around “formula fraud” and manipulating Google to believe that a website was the best answer to a search query.

This should never be the case and instead SEO should focus on achieving the best possible result on the web, instead of figuring it out.

SEO with a hat can seem like a quick way to improve your rankings and increase your search exposure. However, be careful when using these techniques. Black hat tactics can do more harm than good to your SEO.

Google’s algorithms were less complicated 10 years ago, especially when it came to detecting web spam.

In the past, many advertisers have used black hat SEO strategies to evaluate websites; however, things have changed. We’ll take a closer look at shutdown strategies if you don’t want to break the webmaster’s algorithm or quality guidelines in this guide.

What is Black Hat SEO?

Google’s Webmaster Guidelines provide the basic rules for your search engine optimization approach. If you use SEO ranking tactics or shortcuts that violate Google’s policies, you are participating in SEO with a black hat that any professional marketer or website owner can stop at any cost.

If Google finds that your website uses SEO techniques with a black hat, they will punish you. Receiving a penalty from Google will cause the search engine to change its PageRank algorithm, lowering the rating of the website or, in the worst case, to remove it completely.

Not sure if you violated Google’s policies? To calm any questions, you can ask a simple question: Is your SEO approach focused on providing value to your readers or just on good rankings? If the intention is related to the ranking, you need to reconsider your plan.

Private blog networks

In the past, private blogging networks (PBNs) were often used by companies seeking immediate delivery of links to new or inefficient property on the site. PBN is a network of high-ranking websites created exclusively for the purpose of building links and maintaining supported content.

These websites are often referred to as “link farms” because they are set to take advantage of the Google PageRank algorithm. Instead of charging for PBN membership, you can automatically expand your reach and offer guest blog posts to reputable sources and forums for long-term SEO benefits.


Disguise is a term that refers to the practice of displaying crawled content that is different from what you present to your users. One method of concealment is to use different slogans, names and definitions that are diametrically opposed to the actual content. There is a high risk that if the search engine finds a cover, the site will be blocked.

The search engine algorithm is constantly being updated, and if you use disguise, they may eventually find it and will permanently prohibit your website from being indexed. In fact, Google blacklisted the German carmaker BMW in February 2006 for violating its guidelines.

the process of filling a web page

Filling by keywords

Keyword stuffing is the process of filling a web page with keywords or numbers to trick a search engine into believing it is important to search. Usually these keywords are not related to the content of the website.

Sometimes these keywords are protected by the user, but are still searched by the search engine. Filling in keywords will degrade the user interface and potentially damage your site’s ranking.

An example of keyword stuffing would be when you write to be ranked “best laptop” using the following copy: “If you’re looking for the best laptop, look no further for the best laptop.” We have the best laptop. The best laptop works seamlessly … and more.

Comment Spam

Although becoming rarer, there was a period in which comment sections were flooded with automated comments written to create feedback. Google’s algorithm has since been modified to remove and discredit links created by spam or bots.

In any case, links created from comment sections are usually marked with HTML “nofollow” tags, which have no effect on your ranking results.

Relationships need to be won, not bought. Google discredits links created from sponsored content or paid guest posts, but rewards the domains to which they are linked based on the quality of their content with PageRank (or “link juice”). In other words, the feedback approach must be normal.

An effective approach to networking begins with the development of real and exclusive value-added materials that readers may find useful. If you can do this, the feedback will automatically flow over time.
