Acronym for search engine optimization and often also used to refer to a person or company that does search engine optimization
Shopping Search Engine
Shopping search engines allow shoppers to look for products and prices in a search environment. Premium placement can be purchased on some shopping search indices.
Spam
Any search engine 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 about what they consider to be spamming, but ultimately any activity a particular search engine deems harmful may be considered spam, whether or not there are published guidelines against it. Example of spam include the creation of nonsensical doorway pages designed to please search engine algorithms rather than human visitors or heavy repetition of search terms on a page this means the search terms are used tens or hundreds of times in a row. These are only two of many examples. Determining what is spam is complicated by the fact that different search engines have different standards. A particular search engine may even have different standards of what's allowed, depending on whether content is gathered through organic methods versus paid inclusion. Also referred to as spamdexing.
Submission
The act to submitting a URL for inclusion into a search engine's index. Unless done through paid inclusion, submission generally does not guarantee listing. In addition, submission does not help with rank improvement on crawler-based search engines unless search engine optimization efforts have been taken. Submission can be done manually this is done by filling online form and then submitting it or automated, where a software program or online service may process the forms behind the scenes.
XML Feeds
A form of paid inclusion where a search engine is "fed" information about pages via XML, rather than gathering that information through crawling actual pages. Marketers can pay to have their pages included in a spider based search index either annually per URL or on a CPC basis based on an XML document representing each page on the client site. New media types are being introduced into paid inclusion, including graphics, video, audio, and rich media.
