Black hat “SEO” refers to a set of practices that are used to increases a site or page’s rank in search engines through means that violate the search engines’ terms of service. Some examples of black hat SEO techniques include keyword stuffing invisible text, doorway pages, adding unrelated keywords to the page content or page swapping (changing the web page entirely after it has been ranked by search engines).
Black Hat SEO Usage
Black hat SEO is more frequently used by those who are looking for a quick financial return on their Web site, rather than a long-term investment on their Web site. Black hat SEO can possibly result in your Web site being banned from a search engine, however since the focus is usually on quick high return business models, most experts who use Black Hat SEO tactics consider being banned from search engines a somewhat irrelevant risk.
invisible or hidden text/links – the text/links added on website’s page that cannot be viewed by users, with the purpose to boost its ranking. Usually, webmasters include text on website’s page that is of the same color as the page background, thus they manipulate search engine results. Nevertheless, this practice together with others is easily identified and punished. Another technique to hide text is to make its font very small.
irrelevant keywords– a lot of keywords that are not related to the content from the page used to increase significantly web site traffic.
page cloaking– a strategy that misleads search engines by showing one content in search engines results, but the page actually contains another content. Besides this, users are also deceived being taken to pages where the content is not that one they were searching for.
content automation– a technique that generates content automatically with the help of a tool and does not require webmaster’s involvement. This content doesn’t include SEO key components (heading, style, images etc.) and its quality is very poor, but a good SEO involves qualitative content, so you can draw conclusions for yourself whether to use Black Hat SEO or White Hat SEO.
duplicate content– one of the worst method that refers to copying and duplicating content from another website. As a rule, search engines index content just once, and every time the same content reappears on another website, it is considered copied, that’s why instead of using this method, it’s better spending time on creating authentic content.
buying/selling links– a strategy to buy/sell links on spam websites which will redirect to your website. Due to this strategy, website’s ranking can boost incredibly, but at the same time it is very risky, because as soon as search engines discover paid links on your website that redirect to other websites or vice-versa, you will lose your ranking forever with no possibility to recover it, regardless of your future investments.
spam-posting or sending messages that will include the link to your website to different people on emails or social networks.
