What Is Blackhat SEO?

Blackhat SEO is a technique used that focuses primarily on the search engines alone. The strategies being used here do not comply with the guidelines of a particular search engine like Google. Thus, the effect would only be temporary. When the search engine can sense there is a manipulation in moving up to the rank, then, the website will face a penalty. Some of the sites being penalised are now sandboxed. There are some that are struggling to be back on track again.
