SPAM

SPAM: Any search marketing method that a search engine deems to be detrimental to its efforts to deliver relevant, quality search results. Some search engines have written guidelines on their definitions and penalties for SPAM. Examples include doorway landing pages designed primarily to game search engine algorithms rather than meet searcher expectations from the advertiser’s clicked-on ad; keyword stuffing in which search terms that motivated a click-through are heavily and redundantly repeated on a page in place of relevant content; attempts to redirect click-through searchers to irrelevant pages, product offers and services; and landing pages that simply compile additional links on which a searcher must click to get any information. Determining what constitutes SPAM is complicated by the fact that different search engines have different standards, including what is allowable for listings gathered through organic methods versus paid inclusion (referred to as spamdexing), whether the listing is from a commercial or research/academic source, etc. Source: Webmaster World Forums
