Keyword spamdexing / keyword spamming / keyword stuffing
These three terms can be used interchangeably to refer to the practice of loading a webpage with too many keywords to the point that the content becomes plain gibberish with absolutely no meaning. Keywords may also be stuffed in meta tags that are invisible to users. In the context of search engine optimization, this is an unethical practice and search engines may penalize sites for keyword stuffing.
