Keyword stuffing is the phenomenon of putting in an unnecessary amount of keywords, even those with absolutely no relevance to the site, into the description and keyword tags of the site. This was a practice that gained immense popularity a few years back when the web was still young and no laws existed to prevent such misuse. As a result, a number of websites instantly skyrocketed to highly appreciable SERPs. However, this practice did not last long as soon enough search engines started formulating laws and modified their formulae to determine ranking which caused either the plummeting of some very high ranking websites or outright bans being placed on some of them.
