As I constantly read what people have to say about black hat SEO, I came across this definition in Wikipedia:
Black hat SEO attempts to improve rankings in ways that are disapproved of by the search engines, or involve deception. One black hat technique uses text that is hidden, either as text colored similar to the background, in an invisible div, or positioned off screen. Another method gives a different page depending on whether the page is being requested by a human visitor or a search engine, a technique known as cloaking.
Search engines may penalize sites they discover using black hat methods, either by reducing their rankings or eliminating their listings from their databases altogether. Such penalties can be applied either automatically by the search engines’ algorithms, or by a manual site review.
One infamous example was the February 2006 Google removal of both BMW Germany and Ricoh Germany for use of deceptive practices. Both companies, however, quickly apologized, fixed the offending pages, and were restored to Google’s list.
What I found interesting is that this definition gives two examples of black hat SEO that are really really outdated. Cloaking by user-agent and keyword masking are a couple of the “oldest tricks in the book” so to speak, and are a couple of tactics that the search engines are now equipped to spot easily and penalize quickly.
If we want a more up-to-date explanation of Black Hat SEO from wikipedia, we have to look up what is being labeled “spamdexing”. This includes much better information such as doorway pages, hidden links, link farms, etc. I recommend the spamdexing page of Wikipedia as a reference to get a base for more Black Hat SEO techniques, since many of those STILL WORK!!!
