Black Hat SEO is a collection of unethical tactics used to boost one’s ranking in Google search results. These methods are known as black hat since they go beyond Google’s search engine standards. Keyword stuffing, cloaking, paid links, doorway pages, hidden content, and duplicate content are some of the most often employed SEO tactics. Let’s take a closer look at each one.

Keyword Stuffing:

The practice of stuffing many keywords into a single sentence is known as keyword stuffing. Stuffing a page with keywords in order to rank higher in search results is referred to as this approach. It is done to manipulate the Google search bot and gain better rankings by repeating and rehashing the same words and sentences.

Duplicate Content

This is one of the strategies in which the website owner just copies content from one page and pastes it into his own. Isn’t it illegal to steal other people’s belongings? The same may be said of content. This is a technique that Google strongly opposes, as it believes in original content.

This approach, which is considered one of the hacker-man techniques, includes showing one version of your website to the Google bot and another to the user.

This is done in two ways:

  • Search engines see an HTML text page, while consumers see a page with CSS, JS, and image-heavy content.
  • Embedding text or keywords inside a page and only displaying it if the user-agent crawling the page is a search engine rather than a human visitor.

Buying Links:

This is a bad practice in which a website owner pays money to another website in exchange for a link. Many agencies sell such paid links, which are frequently spotty and of poor quality. You’d be better off if you didn’t have any hazardous connections on your site.

Doorway Pages:

Door pages, bridge pages, and jump pages are produced expressly for specific queries and are designed to score well for specific keywords. These pages have little value for the user and are solely designed to fool the search engine and redirect a visitor from a searched query to a different collection of websites, i.e. a hazy destination.

Link Farming:

A link farm is a website or a collection of websites dedicated solely to link building. A link farm is a collection of websites that all point to a site that should be ranked better in search engine results pages. Web crawlers rate a site based on the number of websites that link to it, as well as other factors. This is exploited by black hat SEO, which increases the amount of backlinks a site receives through link farms.

Invisible Text or Links:

This technique involves overlaying white text on a white backdrop, which is a fairly shoddy attempt. The goal here is to have the text colour match the background colour. By doing so, website owners hide their keywords from consumers while allowing the Google bot to see them. For links, a similar procedure is followed.

Spamming in Blog Comments

The intellectuals and scholars in the comments area, oh, the intellectuals and scholars in the comments section. This method entails leaving comments on blog sites and including a link to their website. This is done only for the purpose of obtaining a backlink from that particular website. Such links from blogs are currently ignored by Google; the website owners have configured the links to no-follow by default.

Incorrect Re-directs:

Redirects are a wonderful way to send a user to a better-functioning page if the one they’re on isn’t working. In such circumstances, website owners utilise 301 redirects. The black hat “experts,” on the other hand, exploit these redirections to send the user to a whole different page. By directing consumers to a page with a faulty URL that they did not want to see, they trick both the Google bot and the users.

Overly optimized pages:

Do you know the expression “too much of a good thing is bad for you”? The same is true for your web pages. Sometimes SEO pros are so focused on optimising their pages that they do a little too much. This contains a variety of On-page features like as over-optimized anchor text, a large number of internal links, keyword-stuffed titles and descriptions, as well as the content.

All of this could backfire, and you could be penalised by Google if your efforts are deemed to be black hat SEO tactics.

Bait and Switch:

When employing Bait and Switch, the first step is to write a page for Google that includes a set of keywords, then change it to different products and projects as your ranking rises. As a result, a user sees something wholly unrelated to the topic they clicked on. This technique, also known as Page Swapping, is intended to deceive people and search engines. Black Hat SEO is defined as unethical SEO tactics.


The term “clickbait” refers to a title that is both spectacular and visible in order to entice readers to click on the link. This is a copywriting technique that involves exaggerating a topic in order to get a visitor to click on a link that leads to irrelevant content. These types of methods are utilised to generate revenue based on the amount of clicks. It’s a popular algorithm in tabloids, and it accounts for a significant portion of Black Hat SEO.

Guest Post Spam:

This is a Black Hat technique for getting backlinks that involves sending letters to bloggers asking them to post an irrelevant article with a do-follow link. Guest blogging activities that include links to such articles can have an impact on a site’s ranking. These linked blogs are still put on irrelevant websites for the sole purpose of link-building, notwithstanding their poor quality.

Negative SEO:

This refers to the practise of adopting black hat SEO techniques to degrade a competitor’s search engine rankings. The steps are as follows:

  • Hacking the website
  • Building numerous spammy links to the website
  • Copying the content and spreading it all over the internet
  • Pointing links to the website using various keywords
  • Removing the best backlinks from the website

Automated Google queries:

This is a form of black hat SEO in which software is used to generate automated searches for specific keywords in order to boost a website’s ranking in search results. Without Google’s authorization, automated inquiries are not permitted. When software is used to send automated Google queries, it indicates the programme is used to increase the total number of searches for a specific keyword in order to rank better in the SERP.

How to Report Black Hat SEO?

There are two instances in which black hat SEO tactics should be reported. The first is when your website is targeted by a malicious hacker, a virus, or spam links as part of a negative SEO campaign. Another example is when interconnected black hat approaches uncover spam-infested Web results for a competitive phrase on which your website ranks. To deal with these issues, you’ll need to use Google Search Central to submit a webspam report. Falsely reporting competitor pages is likewise seen as a black hat practice.

If your website has been infected with a virus or malware, you can request a malware evaluation once the bad code has been removed.

If your website is the focus of negative SEO tactics, use Google Search Central’s Disavow Links ToolOpens in a new tab. after contacting the Webmasters who are referring such links to your site to get them removed.

Why Should One Avoid Black Hat SEO?

  • Although black hat SEO is not illegal, it does violate search engine webmaster standards.
  • Pages that show signs of using black hat SEO practises are often de-ranked immediately, with the possibility of “domain blacklisting” as one of the measures in domain penalties.
  • If you receive a Google penalty, you will either fall further down the search results or be completely eliminated. As a result, the website will receive less traffic and fewer customers. While some companies provide Google penalty recovery services, it is advisable to avoid engaging in such actions in the first place.
