Many websites depend largely on search engine traffic to survive. This means Search Engine Optimization (SEO) plays a key role when it comes to determining their growth. However, if you try to use ‘black hat’ SEO tactics (i.e. bad practices with severe penalties) to climb through the rankings faster, you may end up hurting your website over the long-term.

In this article, we’ll give you a quick introduction to black hat SEO and why it doesn’t pay off. Then we’ll break down some black hat techniques you need to avoid if you don’t want your website to be penalized.

Let’s talk SEO!

What Black Hat SEO Is (And Why It’s Bad For Your Site)

Black hat SEO is a catch-all term for any technique aiming to improve your search rankings using sketchy or unethical approaches. In theory, the most relevant content should always show up first among results. However, search engines aren’t perfect. They’re powered by algorithms, and although their precise inner workings aren’t transparent, some can still game the results.

For example, you used to be able to fill your pages with the keywords you wanted to rank for, and get them displayed among the top spots on Search Engine Results Pages (SERPs). This technique is called ‘keyword stuffing‘, and search engines are now pretty good when detecting it. If those search engines think you’re trying to pull a fast one, chances are your site will get penalized. On that note, let’s break down the downsides of approaching SEO using black hat techniques:

  • It can hurt your rankings over the long term. Search algorithms are constantly improving to provide better results. One of the ways they do this is by penalizing sites looking to game the results.
  • Your traffic can die suddenly due to algorithm updates. Even if your nefarious SEO tactics are paying off, a single update to a search engine’s algorithm can tank most of your traffic.
  • It usually leads to poor-quality content. In our experience, the types of sites engaging in black hat SEO aren’t usually too concerned with quality, and it shows.

Just to give you an idea of what black hat SEO might look like, imagine you’re running two blogs about exercise equipment. For one of them, you focus on creating the best articles, reviews, and comparison articles you can. You also put in a lot of effort researching keywords. However, you only use them when it makes sense within the context of each article.

For your other site, you decide to play it fast and loose when it comes to SEO. You put up keywords anywhere you can, buy links from sketchy online marketplaces, leave spam comments on other sites leading back to your blog, and more. In short, you decide to pull every dirty trick in the book to get an edge.

The second blog might get more visitors at first. However, we’d be willing to bet few of them would be willing to return. After all, quality content was not a priority. On the other hand, your first blog might take several months to start getting decent traffic. However, you won’t need to worry about search engine penalties or updates that cut your traffic by half. If you keep working on new and relevant content, traffic should flow to you.

What Black Hat SEO Looks Like (And 6 Techniques You Should Avoid)

Black hat SEO techniques are pretty easy to spot in most cases. However, if you’re new to SEO, you might mistake some black hat methods as legitimate. Here are six of the most common black hat SEO techniques you should avoid!

1. Keyword Stuffing

We already touched upon keyword stuffing during the last section, so let’s dive right into an example. Imagine you’re writing a blog post about “running shoes in 2018” and you start it off with a paragraph similar to this one:

Finding the best running shoes in 2018 is tough. There are hundreds of best running shoes in 2018 to choose from. If you pick the wrong running shoe for you, your feet won’t thank you for it.

Unless you’re a robot, your posts should never read anything like the above. To be fair, there isn’t a metric for how often you should use keywords within your content. The best we can recommend is you only use them when it makes sense to do so.

The logic behind keyword stuffing is that search engines rely on keywords and metadata to make sense of your content. So, it stands to reason the more times you use a keyword, the more relevant search engines might think your pages are for particular queries.

It sounds reasonable. However, as you might imagine, search engines have adapted to detect this approach. In addition, they also penalize websites using the tactic by simply not displaying the offending content.

The next time you’re working on an article, and you’re not sure if you’re overdoing it when it comes to keywords, just go over it a few times. Make sure what you’re saying sounds natural, and if possible, get another set of eyes to go over it. You can even use Yoast SEO or another plugin to monitor keyword density and usage. If you’re overdoing it with the keywords, chances are it’ll be noticeable to others.

2. Buying Links

One of the ways search engines determine what content is the ‘best’ is by checking how many other websites are linking back to it. The logic is that if your content is good, other sites will want to share it with their visitors.

In fact, backlinks are one of the most important criteria search engines use to rank your website. A lot of unscrupulous people take advantage of this by offering to place links on their sites leading back to yours:

Two examples of link sellers.

It sounds like a reasonable proposition since you both get something you want. However, if someone is selling links, chances are you’re not their only client. They’ll want to sell as many as possible, so search engines might mark them as spam.

The result usually is that you’ll waste money on links not helping your site rise in the SERPs. In fact, you might get penalized for them. As for the person who sold those links to you, they’ll probably just keep trying to swindle more people out of their money.

3. Article Spinning

As far as black hat SEO techniques go, article spinning is one of the most egregious. The concept is to find articles targeting the same topics you want to write on, then rewrite them just enough so search engines won’t notice they’re essentially the same content. For example, here’s another version of this same paragraph:

When it comes to black hat SEO, there are few techniques worse than article spinning. It involves finding posts that tackle the same ideas you want to publish, and changing their wording enough to make them appear unique.

To be fair, chances are you’ll find plenty of other people have already tackled a lot of the same subjects you may want to. However, this doesn’t mean it’s impossible to write original articles. It’s always possible to take a shot at the same ideas other people have and improve on them without copying their content in the slightest.

On top of being unethical, a lot of services enable people to detect when someone copies their content. You might fool those services and search engines. However, with all the effort it would take, you’d be better off writing original articles in the first place.

4. Markup Spam

Schema markup is a type of code you can add to your pages so search engines can understand their contents better. With schema markup, you can completely overhaul your meta descriptions and transform them into rich snippets, like this one:

Two examples of rich snippets.

The more information you give search engines, the more likely the algorithm knows when to display your pages. Plus, rich snippets feature a higher Click-Through Rate (CTR) than normal links. Thus, it makes sense to use them whenever possible.

Using keywords within your markup makes sense. However, the same rules apply to schema markup as they do to the rest of your content. You should never try to spam keywords within your markup or your meta description. Not only will search engines be able to tell but cramming a lot of keywords into a short paragraph almost never sounds good (remember the example from the first section!).

5. ‘Web Rings’

Web rings are groups of websites that link to each other in an attempt to fool search engines into believing they’re more popular than they are. For example, imagine you have four websites all on a similar niche, and you use each of them to discuss slightly different content. Then, you add links to each other whenever it makes sense to do so within your content.

It sounds pretty cut and dry. However, search engines are good at catching this practice. After all, it’s pretty obvious what’s going on if you have a group of websites only linking to each other.

Even if you take precautions to also link to other sites, the backlinks you do get might not benefit you. After all, search engines not only care about the number of links, but their quality. However, if you’re part of a web ring with top-notch websites and content, you might get good results.

However, if you’ve got a popular website with a lot of great content, you should be getting backlinks without having to enter shady arrangements. If you’re having problems building links to your site, there are plenty of white hat SEO alternatives you can try without succumbing to the dark side.

6. Blog Comment Spam

Last but not least, we’ve got comment spam, which is one of the most obvious and least effective black hat SEO techniques. You’ve probably run into comments like the following at some point on the web:

An example of blog comment spam.

In some cases, they will  at least make an effort to write a comment relating to the article. However, their main goal is to add a link to their website from yours. Instead of buying links or exchanging them, people just spam them anywhere they can.

According to some sources, link-building using blog comments can have a positive impact on your website. However, you also need to understand a lot of people will dismiss your comments as spam. Some websites might even remove them or ban you from commenting outright.

The right approach, in this case, is only to include links to your website whenever they’re relevant and not tack them as an afterthought to your comments. Even then, you should only use this technique sparingly in order to play it safe.


Growing a website’s organic traffic takes time. When it comes to SEO, there aren’t any shortcuts you can take. If someone tells you otherwise, they’re probably trying to sell you something. The good news is, as long as you keep publishing great content, your search engine rankings should improve organically.

There are a lot of black hat SEO techniques you need to avoid, such as keyword stuffing and buying links. Generally speaking, if a method seems somewhat sketchy, you’d best listen to your instincts and walk away!

  1. Website clients sometimes ask for black hat SEO techniques. They’ve heard of specific “tricks” that can help SERP such as keyword stuffing. Articles like the one you posted are great tools in helping to define what SEO work isn’t so that the conversation can return to what SEO work is. Keeping up with the updates can help drive repeat business, as, for example, the Aug 1 update impacted “health/wellness verticals” so a quick call to that segment of your client base can not only let them know that you have their best interest at heart but that you are actively looking out for them.

    • You are right. Some people want quick results for their website and not bothered what happens in the long run. They go for this Black Hat SEO along with adwords. By the time search engines punish, they already made their money.

  2. Detailed and practical article,
    Speaking of black hat seo technique, any seoer will surely do once the problems are done where?
    Five years ago I was doing spamming at the footer of the site that I wanted to place the keyword.
    But now things are not as effective as I would like and I change the way they gradually move in new directions, softer, more natural 🙂

  3. There’s more and more of this garbage now, but Googlebots are getting smarter every day as well! The two examples you got there, the two images of “Buying Links” are hilarious!

  4. Hi John, I am new to blogging and suffering very badly from spam comments on my blog. I am using WordPress for blogging. Can you please suggest if there is any free wordpress plugin to stop spam comments?

    • I’d recommend Akismet. It actually comes pre-installed with all WordPress installations. All you have to do is create an account with them and activate it. It’s not 100% free but very affordable and really effective.

      • Would this count as comment spinning? 😉

  5. Unusual link building is obviously one of the black hat seo techniques. But, it is complicated when some famous companies which doing white hat seo techniques (like Attracta) sell backlink packages at the same time!

  6. wonderfull information thank q for sharing a grate list and blog

    • You’re welcome. 🙂

  7. My belief is that if you write or say what is relevant, over a period of time it will get noticed. In panchtantra it is said – slow and steady wins the race. Black hat will always be BLACK PERIOD.

    • Correct, Sanjeev!

  8. Hello John Hughes,

    First of all thank you so much for clearing all the doubts about the Black Hat SEO. Because many of us trying to rank fast in Google SERP and start building spam backlinks but it does not stay for a long term and at the end, all the efforts are totally waste.

    Here I just want to ask you that for a short-term blog black hat seo is still working or not?

    • In a nutshell, no. Black Hat SEO is dangerous and is not something we can recommend, which I hope is clear in the article.

      Thanks for your insight and question!
