Can refer to unwanted data sent via email or put on a website to game a search engine. You’re probably aware of spam in the classic email sense and hopefully also aware of the strict standards and penalties associated with the CAN-SPAM Act. Spam to a search engine is Web content that the search engine deems to be detrimental to its efforts to deliver relevant, quality search results. Some search engines have written guidelines about what they consider to be spamming, but ultimately any activity a search engine deems harmful may be considered spam, whether or not there are published guidelines against. Examples of spam include the creation of nonsensical doorway pages designed to pleased search engine algorithms rather than human visitors, or heavy repetition of search terms within a page (i.e., the search terms are used tens or hundreds of times in a row). Spam derives its name from a popular Monty Python skit.
