File not found. This error happens when a user requests a page that is
no longer present. This can be caused if the file has been moved, deleted
The number of page views a site has available for advertising.
Words that are censored by search engines. These include the FCC's seven
forbidden words. Search engines often maintain two databases, to allow a
user to search all data or to filter offensive results.
Agent Name Delivery
The process of sending search engine spiders to a tailored page, yet
directing your visitors to what you want them to see. This is done using
Server Side includes (or other dynamic content techniques). SSL, for
example, can be used to deliver different content to the client depending
on the value of HTTP_USER_AGENT. Most normal browser software packages have
a user agent string which starts with "Mozilla". Most search engine spiders
have specific agent names, such as "Scooter", "Googlebot", "Lycos spider"
A set of rules that a search engine uses to rank the listings contained
within its index, in response to a particular query. No search engine
reveals exactly how its own algorithm works, to protect itself from
competitors and those who wish to spam the search engine. (it is the
mathematical program formula used to determine which web pages are
displayed in search results and what order).
Algorithmic Results; see Organic
A popular search engine. AllTheWeb is the main search engine for
FAST available at AllTheWeb.com.
A popular search engine, available at
An HTML "tag" that allows a browser to display text instead of a
graphic. Some search engines read these tags in order to help with
rankings. All images can be given an ALT tag.
The default search engine for users of the AOL Internet service
provider, and thus a busy site.
Apache Web Server
The leading web server software of the Internet. Apache is an open
A small program, often written in Java, which usually runs in a web
browser, as part of a web page. It is possible that the use of such a
program may cause spiders and robots to stop indexing a page.
A Meta search engine which can be asked questions in common English
Active Server Pages, a server based scripting language that is used to
provide dynamic content and build database driven web sites where the
browser may not have any scripting.
All the links pointing at a particular web page. Also called inbound
links. Source: Webmaster World Forums
When pages are removed from a search engine's index specifically because
the search engine has deemed them to be spamming or violating some type of
It started out as referring to specific content management software
(blogger), and has transitioned into a description for a wide range of
personal pages, journals, and diary type setups.
A search allowing the inclusion or exclusion of documents containing
certain words through the use of operators such as AND, NOT and OR.
Best of Web, a reference to one search engine that classifies its core
set of sites as "the best of web". BOW is also used as a reference to the
BOW TIE theory. It states that the core of the web is a central hub with
two off shoots extending in either direction. A graphical map of that
theory appears to look like a Bow Tie.
IP Addresses are 4 digits between 0 and 255. (Example:111.222.333.233).
Each number represents a "class" that is most often denoted as A-C
(Example: aaa.bbb.ccc.ddd). A "c-class"refers to the 255 addresses
from "xxx.xxx.xxx.001" to "xxx.xxx.xxx.255".
Common Gateway Interface - a standard interface between web server
software and other programs running on the same machine. In practice, CGI
programs are used to handle forms and database queries on web pages, and to
produce non-static web page content.
The percentage of those clicking on a link out of the total number who
see the link. For example, imagine 10 people do a web search. In response,
they see links to a variety of web pages. Three of the 10 people all choose
one particular link. That link then has a 30 percent clickthrough rate.
Also called CTR.
A computer, program or process which makes requests for information from
another computer, program or process. Web browsers are client programs.
Search engine spiders are (or can be said to behave as) clients.
In terms of search engine marketing, this is the act of getting a search
engine to record content for a URL that is different than what a searcher
will ultimately see. (Hiding of page content). It can be done in many
technical ways. Several search engines have explicit rules against
unapproved cloaking. Those violating these guidelines might find their
pages penalized or banned from a search engine's index. As for approved
cloaking, this generally only happens with search engines offering paid
inclusion program. Anyone offering cloaking services should be able to
demonstrate explicit approval from a search engine about what they intend
to do. If not, then they should then have explained the risks inherent of
unapproved cloaking. (Using cloaking a web site will submit a page built
purely to rank high for a search engine algorithm and then display
completely different content for human users).
The listing of only one page from each web site in a search engine or a
directory's list of search results. This avoids occupation of all the top
results of a query by a small number of web sites and provides a cleaner
more useful list of results to the user.
A CGI database program from Allaire. Cold fusion uses a file extension
of cf or cfm. Also used by some cloaking programs.
The HTML <-- and --> tags are used to hide text from browsers. Some
search engines ignore text between these symbols but others index such text
as if the comment tags were not there. Comments are often used to hide
invisible keywords to some search engines.
A search for documents related conceptually to a word, rather than
specifically containing the word itself.
Contextual Link Inventory
To supplement their business models, certain text-link advertising
networks have expanded their network distribution to include "contextual
inventory". Most vendors of "search engine traffic" have expanded the
definition of Search Engine Marketing to include this contextual inventory.
Contextual or content inventory is generated when listings are displayed on
pages of Web sites (usually not search engines), where the written content
on the page indicates to the ad-server that the page is a good match to
specific keywords and phrases. Often this matching method is validated by
measuring the number of times a viewer clicks on the displayed ad.
The relationship between visitors to a web site and actions consider to
be a "conversion," such as a sale or request to receive more information.
Often expressed as a percentage. If a web site has 50 visitors and 10 of
them convert, then the site has a 20 percent conversion rate.
Cost Per Click
System where an advertiser pays an agreed amount for each click someone
makes on a link leading to their web site. Also known as CPC.
A counter counts hits or page views to a web site. Counter quality and
features can vary widely. Most common are image tag counters that are
activated when anyone views a page with the graphics enabled.
CPC; see Cost Per Click.
System where an advertiser pays an agreed amount for the number of times
their ad is seen by a consumer, regardless of the consumer's subsequent
action. Heavily used in print, broadcasting and direct marketing, as well
as with online banner ad sales. CPM stands for "cost per thousand," since
ad views are often sold in blocks of 1,000. The M in CPM is Latin for
Component of search engine that gather listings by automatically
"crawling" the web. A search engine's crawler (also called a spider or
robot), follows links to web pages. It makes copies of the web pages found
and stores these in the search engine's index.
A reference to "Cross Browser" is usually in relation to java script,
html, or css code that can work in multiple browsers.
Cross linking is linking across content within the same site.
CTR; see Clickthrough Rate.
An Internet link which doesn't lead to a page or site, probably because
the server is down or the page has moved or no longer exists.
Linking to content buried deep within a web site. The link is referred
to as "deep" because it is often linked to content found two or more
directories deep within a web site.
When pages are removed from a search engines index. This may happen
because they have been banned or for other reasons, such as an accidental
glitch on the search engine's part.
Descriptive text associated with a web page and displayed, usually with
the page title and URL, when the page appears in a list of pages generated
by a search engine or directory as a result of a query. Some search engines
take this description from the DESCRIPTION Meta tag – others generate their
own from the text in the page. Directories often use text that was provided
A system which monitors the search engine users' selections from search
engine results, counting which results are clicked on most, and how long
visitors spend at that site. This is done so as to improve the relevancy of
A type of search engine where listings are gathered through human
efforts, rather than by automated crawling of the web. In directories, web
sites are often reviewed, summarized in about 25 words and placed in a
Sometimes referred to as Reverse Domain Name Server Lookup. Most often
used by webmasters while looking at server log files. It converts a unique
IP address of a site visitor to its domain name.
A Meta search engine. Found at
An Internet address. The most significant part of the address comes at
the end. Typical top-level domains are .com, .edu, .gov, .org. There are
also various geographic top-level domains (e.g, .ar, .ca, .fr, .ro, etc.)
A web page created expressly in hopes of ranking well for a term in a
search engine's non-paid listings and which itself does not deliver much
information to those viewing it. Instead, visitors will often see only some
enticement on the doorway page leading them to other pages (i.e., "Click
Here To Enter), or they may be automatically propelled quickly past the
doorway page. With cloaking, they may never see the doorway page at all.
Several search engines have guidelines against doorway pages, though they
are more commonly allowed in through paid inclusion programs. Also referred
to as bridge pages, gateway pages and jump pages, among other names.
Information on web pages that change or is changed automatically, e.g.
based on database content or user information. Sometimes it's possible to
spot that this technique is being used, e.g. if the URL, ends with .asp,
.cfm, .cgi or .shtml. It is possible to serve dynamic content using
standard (normally static) .htm or .html type pages, though Search engines
will currently index dynamic content in a similar fashion to static
content, although they will not usually index URLs which contain the "?"
Dynamic IP Address
An IP address that changes each time you connect to the Internet.
Sometimes refers to a single page with a logo and "click here" link to
Earnings per Click.
Earnings per Visitor.
Previously a popular search engine with its own database, it has now
been transformed into a popular Meta search engine. Available at
Free For All links. These are places that allow anyone to add a link.
Search engines do not endorse FFA and ignore them. FFA has become one of
the biggest sources of email addresses for spammers.
An HTML technique for combining two or more separate HTML documents
within a single web browser screen. A framed web site often causes great
problems for search engines, and may not be indexed correctly.
The maximum number of times or length of times a site visitor will be
shown the same or related advertisement.
An index containing every word of every document cataloged, including
A search that will find matches even when words are only partially
spelled or misspelled.
A web page submitted to a search engine (spider) to give the
relevance-algorithm of that particular spider the data it needs, in the
format that it needs it, in order to place a site at the proper level of
relevance for the topic(s) in question.

where web sites can pay to increase their hierarchy. The URL is
Graphical Search Inventory. Banners, and other types of advertising
units which can be synchronized to search keywords. Includes pop-ups,
browser toolbars and rich media.
Many search engines give extra weight and importance to the text found
inside HTML heading sections. It is generally considered good advice to use
headings when designing web pages and to place keywords inside headings.
Text on a web page which is visible to search engine spiders but not
visible to human visitors. This is sometimes because the text has been set
the same color as the background. Hidden text is often used for spamdexing.
Many search engines can now detect the use of hidden text, and often remove
offending pages from their database or lower such pages' positioning.
In the context of visitors to web pages, a hit (or site hit) is a single
access request made to the server for either a text file or a graphic. If,
for example, a web page contains ten buttons constructed from separate
images, a single page will involve eleven hits on the server. In the
context of a search engine query, a hit is a measure of the number of web
pages matching a query returned by a search engine or directory.
A search engine converted into a Meta search engine that displays
results from Google, Teoma, Inktomi and Fast. The URL is
HyperText Markup Language – the (main) language used to write web pages.
A set of hyperlinks attached to areas of an image. This may be defined
within a web page, or as an external file.
A hypertext link to a particular page from elsewhere, bringing traffic
to that page. Inbound links are counted to produce a measure of the page
popularity. Searches for inbound links to a page can be made on Altavista,
Google and Hotbot.
The collection of information a search engine has that searchers can
query against. With crawler-based search engines, the index is typically
copies of all the web pages they have found from crawling the web. With
human-powered directories, the index contains the summaries of all web
sites that have been categorized.
A failed search engine that now redirects its traffic to Go.com. The URL
The database of web sites used by some of the largest search engines.
Owned by Yahoo.com
Whenever you connect to the Internet, you are giving a unique 4 number
Internet Protocol Address (IP Address). Your IP address is how data finds
its way back and forth from your computer to a particular web site. Your IP
address may change each time you attach to your ISP. If your IP address
stays the same from connection to connection, you are said to have a static
IP address. If it changes each time you connect, you are said to have a
dynamic IP address. IP addresses can be important in the context of search
engine submission because some search engines have been known to ignore
submissions from any one IP over a certain limit.
Similar to agent name delivery; this technique presents different
content depending on the IP address of the client. It is very difficult to
view pages hidden using this technique, because the real page is only
visible if your IP address is the same as (for example) a search engine's
A computer programming language whose programs can run a on a number of
different types of computers and/or operating systems. Used extensively to
produce applets for web pages.
A simple interpreted computer language used for small programming tasks
within HTML web pages. The scripts are normally interpreted (or run) on the
client's computer by the web browser. Some search engines have been known
to index these scripts, presumably erroneously.
A word which forms (part of) a search engine query.
A property of the text in a web page which indicates how close together
the keywords appear. Some search engines use this for positioning.
Analyzers are available which allow comparisons between pages. Pages can
then be produced with similar keyword densities to those found in high
Keyword Domain Name
The use of keywords as part of the URL to a web site. Positioning is
improved on some search engines when keywords are reinforced in the URL.
A phrase which forms (part of) a search engine query.
The buying of search keywords from search engines. Overture is the main
seller of keywords.
A search for documents containing one or more words that are specified
by a user.
The repeating of keywords and keyword phrases in META tags or elsewhere.
The specific web page that a visitor ultimately reaches after clicking a
search engine listing. Marketers attempt to improve conversion rates by
testing various landing page creative, which encompasses the entire user
experience including navigation, layout and copy.
A count of the number of links pointing (inbound links) at a web site
and links pointing out (outbound links). Many search engines now count
linkage in their algorithms.
Free for All links. These are places that allow anyone to add a link and
are viewed as spam by the search engines.
A reference to when URLs are removed and the URL goes 404.
A raw count of how "popular" a page is based on the number of backlinks
it has. It does not factor in link context or link quality, which are also
important elements in how search engines make use of links to impact
The text that is contained within a link. For example, search engine is
a link that contains the link text "search engine."
The information that appears on a search engine's results page in
response to a search.
Files maintained on a server in which details of all file accesses are
stored. Analyzing log files can be a powerful way to find out about a web
site's visitors, where they come from and which queries are used to access
a site. Various software packages are available to analyze log files.
A program that logs web page views. Most often a logger will also track

Meta Search Engine
A search engine that gets listings from two or more other search
engines, rather than through its own efforts.
Information placed in a web page not intended for users to see but
instead which typically passes information to search engine crawlers,
browser software and some other applications.
Meta Description Tag
Allows page authors to say how they would like their pages described
when listed by search engines. Not all search engines use the tag.
Meta Keywords Tag
Allows page authors to add text to a page to help with the search engine
ranking process. Not all search engines use the tag.
Meta Robots Tag
Allows page authors to keep their web pages from being indexed by search
engines, especially helpful for those who cannot create robots.txt files.
The Robots Exclusion page provides official details.
Multiple copies of web sites or web pages, often on different servers.
The process of registering these multiple copies with search engines is
often treated as spamdexing because it artificially increases the relevancy
of the pages. Filters now automatically remove many of these mirrors from
People quite often spell words incorrectly when using search engines.
Pages which use common misspellings will often receive extra hits, so it is
a useful technique to include common misspellings of words in ALT tags,
keywords, page names and titles. A similar effect occurs when spaces are
missed out and words are accidentally joined together.
Multiple Domain Names
The use of several extra domains to provide gateway pages or gateway
sites to the main site.
A search engine with a "pay to access" collection of business, health
and consumer publication articles. The URL is
The act of misrepresenting Meta tags or content. The user is presented
with a page that looks normal, but it is not the page submitted to search
engines. This is similar to cloaking or stealth pages, but it further
protects the code by giving code stealers a Mickey page. The page
often looks normal, but there will be something wrong with it to cause it
to rank low on search engines (things like bad keyword density or Meta tag
errors). When someone steals a high ranking page like this and installs it
on their own server, they will never get the rankings the real page gets.
Listings that search engines do not sell (unlike paid listings).
Instead, sites appear solely because a search engine has deemed it
editorially important for them to be included, regardless of payment. Paid
inclusion content is also often considered "organic" even though it is paid
for. This is because that content usually appears intermixed with unpaid
Links on a particular web page leading to other web pages, whether they
are within the same web site or other web sites.
Advertising program where pages are guaranteed to be included in a
search engine's index in exchange for payment, though no guarantee of
ranking well is typically given. For example, LookSmart is a directory that
lists pages and sites, not based on position but based on relevance.
Marketers pay to be included in the directory, on a CPC basis or per-URL
fee basis, with no guarantee of specific placement. Also see XML Feeds.
Listings that search engines sell to advertisers, usually through paid
placement or paid inclusion programs. In contrast, organic listings are not
Term popularized by some search engines as a synonym for pay-per-click,
stressing to advertisers that they are only paying for ads that "perform"
in terms of delivering traffic, as opposed to CPM-based ads, where ads cost
money, even if they don't generate a click.
Pay-Per-Click; see Cost Per Click.
Advertising program where listings are guaranteed to appear in response
to particular search terms, with higher ranking typically obtained by
paying more than other advertisers. Paid placement listings can be
purchased from a portal or a search network. Search networks are often set
up in an auction environment where keywords and phrases are associated with
a cost-per-click (CPC) fee. Overture and Google are the largest networks,
but MSN and other portals sometimes sell paid placement listings directly
as well. Portal sponsorships are also a type of paid placement.
The process of ordering web sites or web pages by a search engine or a
directory so that the most relevant sites appear first in the search
results for a particular query. Software can be used to determine how a URL
is positioned for a particular search engine when using a particular search
A method of modifying a web page so that search engines (or a particular
search engine) treat the page as more relevant to a particular query (or a
set of queries).
Stands for pay-per-click and means the same as cost-per-click. See
Cost Per Click.
A word, a phrase or a group of words, possibly combined with other
syntax used to pass instructions to a search engine or a directory in order
to locate web pages.
A search where a user instructs an engine to find more documents that
are similar to a particular document. Also called "find similar".
Rank or Ranking
How well a particular web page or web site is listed in a search engine
results. For example, a web page about apples may be listed in response to
a query for "apples." However, "rank" indicates where exactly it was listed
-- be it on the first page of results, the second page or perhaps the 200th
page. Alternatively, it might also be said to be ranked first among all
results, or 12th, or 111th. Overall, saying a page is "listed" only means
that it can be found within a search engine in response to a query, not
that it necessarily ranks well for that query. Also called position or
positioning. (in the context of search engines, it is the position that a
sites entry is displayed in a search engine query results).
A link exchange between two sites.
The URL of the web page from which a visitor came. The server's referrer
log file will indicate this. If a visitor came directly from a search
engine listing, the query used to find the page will usually be encoded in
the referrer URL, making it easy to see which keywords are bringing
visitors. The referrer information can also be accessed as document
(accessible from scripting languages).
Meta Refresh tag reloads a page at a set time.
How well a document provides the information a user is looking for, as
measured by the user.
The method a search engine or directory uses to match the keywords in a
query with the content of each web page, so that the web pages found can be
ordered suitably in the query results. Each search engine or directory is
likely to use a different algorithm, and to change or improve its algorithm
from time to time.
Registration; see Submission.
After a user enters a search query, the page that is displayed, is call
the results page. Sometimes it may be called SERPs, for "search engine
results page." Source: Webmaster World Forums
Any browser program which follows hypertext inks and accesses web pages
but is not directly under human control. Examples are the search engine
spiders, the "harvesting" programs which extract e-mail addresses and other
data from web pages and various intelligent web searching programs.
A text file stored in the top level directory of a web site to deny
access by robots to certain pages or sub-directories of the site. Only
robots which comply with the Robots Exclusion Standard will read and
obey the commands in this file. Robots will read this file on each visit,
so that pages or areas of sites can be made public or private at any time
by changing the content of robots.txt before re-submitting to the search
Stands for "Return On Investment" and refers to the percentage of profit
or revenue generated from a specific activity. For example, one might
measure the ROI of a paid listing campaign by adding up the total amount
spent on the campaign (say $200) versus the amount generated from it in
revenue (say $1,000). The ROI would then be 500 percent. Or often referred
to sales per lead.
RON: Run of Network. Large advertising brokers can sell ads across the
entire network of member sites.
ROS: Run of Site. An ad that can be placed anywhere on a web site
The name of the Altavista search engine's spider.
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. Some of the major search
engines are AltaVista, Google, Teoma, and AllTheWeb. Note: that Yahoo is a
directory, not a search engine. The term Search Engine is also often used
to describe both directories and search engines.
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
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.
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
Search Engine Marketing Professional Organization, a non-profit, formed
to increase the awareness of and educate people on the value of search
Acronym for search engine optimization and often also used to refer to a

Short for "Search Engine Results Page". This is the page that is
generated by a search engine in response to a search query.
A computer, program or process which responds to requests for
information from a client. On the Internet, all web pages are held on
servers. This includes those parts of the search engines and directories
which are accessible from the Internet.
Server Side Includes
A means of creating a 'template' web page, which places some standard
text in a set of web pages or applies a consistent appearance across a set
of web pages.
The use of various means to steal another site's traffic. Techniques
used include the wholesale copying of web pages (with the copied page
altered slightly to direct visitors to a different site, and then
registered with the search engines) and the use of keywords or keyword
phrases "belonging" to other organizations, companies or web sites.
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.
The name of the spider used by Inktomi.
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.
That part of a search engine which surfs the web, storing the URLs and
indexing the keywords and text of each page it finds.
The process of surfing the web, storing URLs and indexing keywords,
links and text. Typically, even the largest search engines cannot spider
all of the pages on the net. This is due to the huge amount of data
available, the speed at which the new data appears, the use of politeness
windows and practical limits on the number of pages that can be visited in
a given time. The search engines have to make compromises in order to visit
as many sites as possible, and they do this in different ways. For example
some only index the home pages of each site, some only visit sites they're
explicitly told about, and some make judgments about the importance of
sites (from number and quality of inbound links) before "digging deeper"
into the subpages of a site.
Similar to a gateway page but provides an initial display which must be
viewed before a visitor reaches the main page. This usually acts as a kind
of "opening title" sequence, and can be extremely annoying.
Server Side Includes. Used (for example) to add dynamically generated
content to a web page.
A CGI script which switches page content depending on who or what is
accessing the page.
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".
A word which is ignored in a query because the word is so commonly used
that it makes no contribution to relevancy. Examples are, common net words
such as computer and web, and general words like get, I, me, the, and you.
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. Useful to get listed with many of
the minor search engines, but don't reply on such services to get listed
with the major search engines. Many of these services are automatic and run
from web sites. Others run offline. Some are free. Beware of supplying your
email address to the so called FFA (free for all) services – you may
receive lots of spam.
Top Level Domain. This is the far right portion of any domain name.
Examples: .com, .org, .uk, .net.
The visitors to a web page or web site. Also refers to the number of
visitors, hits, accesses, etc., over a given period.
The Lycos spider.
A real visitor to a web site. Web servers record the IP addresses of
each visitor, and this is used to determine the number of real people who
have visited a web site. If for example, someone visits twenty pages within
a web site, the server will count only one unique visitor (because the page
accesses are all associated with the same IP address) but twenty page
Universal Resource Locator. An address which can specify any Internet
resource uniquely. The beginning of the address indicates the type of
resource – e.g. http: for web pages, ftp: for file transfers, telnet: for
computer login sessions or mailto: for e-mail addresses.
The process of submitting a webpage to search engines.
Each time a web browser or other client connects to a web site, they
report a USER_AGENT. Common user agents include Netscape, Opera, and
Internet Explorer. In the context of Search Engine Robots or Spiders, a CGI
program can read the USER AGENT and deliver custom content to that user or
robot. The User Agent can also be included in a robots.txt file to allow or
deny access to the web site.
A domain hosted by a virtual server account.
An account on a hosting company server, usually linkedc to its own
domain. This provides an inexpensive way to run a web site with its own top
level domain, and is usually indistinguishable from having a separate
physical server, except that the virtual server may share an IP address
with other virtual servers on the same machine. A virtual server account is
fine for most uses, but will often be slower to respond than a physically
separate server, and physical access to the machine will seldom be allowed.
The cost of a virtual server account is a small fraction of that needed to
run a real server, mainly because of the expense of the dedicated line
needed to connect the server continuously to the rest of the net.
Extensible Markup Language. A new language which promises more efficient
data delivery over the web. XML does nothing itself – it must be
implemented using 'parser' software.
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.
Extensible Scripting Language – and XML style sheet language supported
by the newer web browsers Internet Explorer 5 and Netscape 5.
Similar to a search engine, but with a database generated by hand. The
URL is http://www.yahoo.com. Yahoo!
Charges an annual fee for each web site to be listed in their database.
