Search Engine
Any service generally designed to allow users to search
the web or a specialized database of information. Web search
engines generally have paid listings and organic listings.
Organic listings typically come from crawling the web, though
often human-powered directory listings are also optionally
offered. Source: Webmaster World Forums
Search Engine Marketing
The act of marketing a web site via search engines, whether
this be improving rank in organic listings, purchasing paid
listings or a combination of these and other search engine-related
activities.
Search Engine Optimization
The act of altering a web site so that it does well in the
organic, crawler-based listings of search engines. In the
past, has also been used as a term for any type of search
engine marketing activity, though now the term search engine
marketing itself has taken over for this. Also called SEO.
Search Terms
The words (or word) a searcher enters into a search engine's
search box. Also used to refer to the terms a search engine
marketer hopes a particular page will be found for. Also
called keywords, query terms or query.
SEM
Acroymn for search engine marketing and may also be used
to refer to a person or company that does search engine
marketing (i.e.., "They're an SEM firm).
SEMPO
Search Engine Marketing Professional Organization, a non-profit,
formed to increase the awareness of and educate people on
the value of search engine marketing.
SEO
Acronym for search engine optimization and often also used
to refer to a person or company that does search engine
optimization (i.e., "They do SEO").
SERP
(Source: http://www.webopedia.com/TERM/S/SERP.html)
Short for search engine results page, the Web page that
a search engine returns with the results of its search.
The major search engines typically display three kinds of
listings on their SERPs. Listings that have been indexed
by the search engine抯 spider, listings that have been indexed
into the search engine抯 directory by a human, and listings
that are paid to be listed by the search engine.
Shopping Search
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 (i.e. the search terms
are used tens or hundreds or 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. Source: Webmaster World
Forums
Spider
See Crawler.
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 (i.e., you fill out
an online form and submit) or automated, where a software
program or online service may process the forms behind the
scenes.
Query
See Search Terms.
Query-By-Example
A search where a user instructs an engine to find more documents
that are similar to a particular document. Also called "find
similar."
Recall
Related to precision, this is the degree in which a search
engine returns all the matching documents in a collection.
There may be 100 matching documents, but a search engine
may only find 80 of them. It would then list these 80 and
have a recall of 80%.
Relevancy
How well a document provides the information a user is looking
for, as measured by the user.
Search Engine
The software that searches an index and returns matches.
Search engine is often used synonymously with spider and
index, although these are separate components that work
with the engine.
Spider
The software that scans documents and adds them to an index
by following links. Spider is often used as a synonym for
search engine.
Stemming
The ability for a search to include the "stem"
of words. For example, stemming allows a user to enter "swimming"
and get back results also for the stem word "swim."
Stop words
Conjunctions, prepositions and articles and other words
such as AND, TO and A that appear often in documents yet
alone may contain little meaning.
Thesaurus
A list of synonyms a search engine can use to find matches
for particular words if the words themselves don't appear
in documents.
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.
