Keyword stuffing is known as an unethical search engine optimization technique that involves adding an excessive amount of keywords into the HTML or tags of a webpage to bring more traffic to a website. While considered obsolete and outdated, there are still websites that attempt to use this technique and end up being blacklisted or banned from search engines. Search engines are now well equipped to deal with that sort of unethical SEO technique. For example, Google, one of the main search engines, has parameters that check for keyword stuffing hidden away from the eyes of the casual website viewer.
