Black hat seo is the process by which we achieve serp’s placement using tactics that are completely unethical. The results are immediate but will not last. When we are caught implementing black hat seo we can face severe consequences like site banning.
These are some of the techniques..
• cloaking and false redirects
• automatically generated doorway pages
• misspelling of well-known web sites
• excessive keyword stuffing
• pages loaded with irrelevant words that do not match the subject
• duplicated content on multiple pages
• hidden text or hidden links
• unrelated and centralized link farms
