What do you mean by Black hat SEO?

Black hat SEO is the name of getting traffic by illegal way. A person visit any type of forum and leave irrelevant comments which are the source of increasing traffic on specific website.
Google did not give power to these sort of SEO.

don’t use black hat, alot of it is spam

Black Hat SEO may also be referred to as Unethical SEO/ Unnatural SEO or just spamdexing, as spamdexing is a typical frequently used Black Hat SEO practice.

The word “illegal” is actually incorrect here. Search engines like Google and Bing are not government so violating their rules are not really illegal. Unethical yes, but illegal? No!

They do, however have interest in providing the best search results for their users, so any attempt by webmasters to manipulate them to push some low quality websites just deserved to be penalized. Moreover, while not illegal, black hat techniques usually work in tandem with other illegal activities such as phishing websites and Nigerian royalty scams.

The previous comments are pretty right.

Black Hat SEO is like junk mail. It often has a lot of volume, but low or negative impact.

What’s even more funny is that people who often claim to do “white hat” SEO are actually not.

There are only two types of SEO which are “white hat”. Content creation on your own site that is keyword optimized and the internal link structure of your own site.

If you do ANYTHING to get links from other sites with the intent of building up your site’s rank and visibility, you’ve crossed to the dark side and are no longer in white hat territory.

You want to build another blog at Wordpress.com or Blogger that has great content on it too but the REAL purpose is to lock in some backlinks…that’s black hat.

You want to write guest posts so that you can get a link back to your site? You’ve gone black.

You want to social bookmark your own site not because you love social bookmarking and use it all the time to find stuff that’s interesting that you never would have found otherwise but instead are doing it for the link juice? Then you’re just covered in black.

The whole discussion continues to crack me up.

Hello

As the name itself suggest that black hat i.e illegal way of doing SEO. the techniques which are not fall under google guidelines then it is called as black hat seo techniques.

If the link builder is actually contributing to the discussion, I don’t think that’s something that can be considered as black hat. With due respect, but this is the first time I encountered an extreme opinion such as yours.

In one of my blogs, I actually removed the default nofollow tag of WordPress but insist that people actually say something about the topic and use their real names.

Is Link Building really Black Hat SEO?

It depends on how you do it. If all you do is to leave “me too” or “I agree” or “that was well thought” or any general statement that can be inserted in any forums or blog comments without contributing to the discussion, then yes.

As far as i know, Black Hat search engine optimization is customarily defined as the practice of using unethical techniques to make your search rankings go up. In search engine optimization (SEO) terminology, Black Hat SEO refers to the use of aggressive SEO strategies, techniques and tactics that focus only on search engines and not a human audience, and usually does not obey search engines rules. Some examples of Black Hat SEO techniques include keyword stuffing, invisible text and doorway pages.
