If you are a member of the online community and have a website, you should be aware of BlackHat SEO practices.  BlackHat practices are different ways to get your site to rank higher in the search engines.  You won’t go to jail for doing anything illegal if you participate in BlackHat SEO, but it will not help your site, it will hurt it.
There are two types of SEO; BlackHat and WhiteHat.  WhiteHat SEO techniques are the usual things that a site does to get seen by the search engines.  This can include keywords, relevant backlinks, blogs, meta tag optimizing, and other items that are ethical.  Working this way can help your site rank higher in the most popular search engines.

BlackHat SEO techniques are more debatable and it’s a pretty unethical way to get your website to look more accepted than it really is.  These practices include irrelevant backlinks, keyword stuffing, and spamming.  All these are well-liked by the marketers who don’t care to act ethically.  These types of people will have automated sites to try and sell you something that probably won’t end up working.

There is no truth to the statement that BlackHat will save you money.  Some people who handle SEO might tell you this; don’t listen to them.  They will say that using BlackHat will save you thousands compared to the regularly used SEO tactics, or WhiteHat.  This is not the case.

Developing a free site and overloading it with keywords is only going to help you for a very short period of time.  Don’t think you can outsmart Google, or any of the other search engines.  They keep changing algorithms to fight those BlackHat practices and the sites that do use them will be banned by Google.
What would it mean to you if you got banned by Google?  True, it is only one search engine.  But you picked the wrong search engine to get banned by; it is the most popular search engine by far.  This will cut your traffic down to a few visitors a day, if that.  If you get blacklisted from Google, people won’t be able to find you when doing keyword searches and other sites won’t want to be affiliated with you.

Now looking at the BlackHat SEO, does it seem worth using?  NO!  Use the ethical White Hat way, so you can be in business for the long run.
