Black Hat SEO Techniques

What is Black Hat SEO?

Black Hat SEO is the use of unfair techniques to promote a site on search engine listing. These techniques may work but the results are likely to be temporary. These sites are often banned if the search engines get wind of these unethical practices.

What are the common Black Hat techniques?

Keyword Stuffing: Overburdening a site with too many keywords at the most unwarranted places is a common black hat technique. Eventually, search engines might ban sites that do this.

Invisible Text: Another method is putting lists of keywords in white text on a white background in order feed different on-page content to search engines and different to users actually browsing the site. It is easy for search engines to detect this.

Doorway or Gateway Pages: Some web developers use the doorway page – a fake page that the user will never see and which would be only visible to search engine spiders. These doorway pages are optimized heavily for search engines and normal users never see it as they are automatically redirected to a different page (you can do that based on user-agent check). It can be easily detected by search engines.
