on a revenue share basis but can also be on a pay per click basis where revenue
is tied to volume of visitors sent rather than their actual spend.
A site traffic ranking tool that uses a sampling approach where data is gathered

CP - Control panel

eg a registrar control panel allows changes to nameserver delegation, contact
CPM - Cost Per Thousand

DNJ - Domain Name Journal
A popular website that lists verified and reported domain sales
on a weekly basis, including a specific new tld chart. The site is at www.dnjournal.com
DNS - Domain Name System
Devices on the internet route data to each other using IP addresses which are
numerical "locations". Sitting on top of these IP addresses are the
more human friendly domain names that we know and love - like google.com. When
a domain name is registered, nameservers have to be specified which have authority
to control what IP address is given in response to a domain name. Different
subdomains can resolve to different IP addresses so alpha.domain.tld can be
configured to resolve to a different IP address than beta.domain.tld for example.
Wildcard DNS can also be employed where everything.domain.tld is configured
to resolve to a specific IP address. Round robin systems can also be employed
where a domain name resolves to a specified list of IP addresses in a predetermined
order to spread the loading across multiple servers.
DRS - Dispute Resolution Service (UK Names)
A dispute service that all .uk registrations are subject to. The complainant
lodged a complaint with Nominet (the UK registry) and the respondent gets to
answer this upon which an informal mediation period begins where a solution
is attempted to be brokered. If no solution is found the complainant can pay
a fee (currently £750 plus VAT) to have the case heard by an expert panel
who can request the domain name be transferred if found in favour of the complainant:
a. A Respondent must submit to proceedings under the Dispute Resolution Service
if a Complainant asserts to us, according to the Procedure, that:
i.The Complainant has Rights in respect of a name or mark which is identical
or similar to the Domain Name; and The Domain Name, in the hands of the Respondent,
is an Abusive Registration.
b. The Complainant is required to prove to the Expert that both elements are
present on the balance of probabilities.
DS - DomainSponsor (also used as an acronym for DomainState)

of the most popular services for this.
No need to introduce the site itself, but google [page] count is often used
to show how popular a term is. This is simply the count Google gives at the
top of the search results page to show how many pages containing the search
it has indexed e.g. "Results 1 - 10 of about 271,000,000 for cars".
When looking up multiple word terms, the term should be enclosed in double quotes
(")to make it meaningful as otherwise it simply returns the number of pages
that contain all the words but not necessarily together as a term.
GTLD - Generic Top Level Domain
Domain extensions (tld's) that are not linked to a specific geographic region
and were originally intended to represent a specific usage e.g. .com (originally

KW - KEYWORD(S)
The word/words used to describe a specific interest. It is used in several ways,
the "domain keyword" is the the domain excluding the tld (extension)

In a domain parking sense this means showing content (ads/keyword links) that
are the mix of relevancy and revenue delivery - this can either be done manually
or via an automated and algorithmic approach that extracts semantic data from
the domain and/or analyzing site visitor behaviour.
OV / OVERTURE / SUGGESTION TOOL
Now part of Yahoo!, overture is the advertising division and is more often used
to represent the "suggestion tool" count. This is data provided by
overture to show the number of searches for a term performed in the previous
month via their network of sites. It is also commonly used to look up full domain
names (with extension) as a form of sampling to see how many times a domain
was entered into the search box to give an idea of how popular a domain name
may be for direct address bar type-in traffic.
Caution should be taken when using overture, it groups like keywords (plural/singular
etc), treats hyphens as a delimiter (the same as it treats spaces), can be influenced
by outside factors (especially on freshly deleted domains) and can just plain
There is a thread going into more detail on overture in relation to traffic
Update: Yahoo rebranded Overture as Yahoo! Advertising and the suggestion tool was eventually taken offline in 2008.

PPC - Pay Per Click
A model where revenue is calculated upon the volume of visitors sent to advertisers
rather than a revenue share approach.
This is where someone accessing a domain name is routed to a different domain
name/URL. There are different methods of doing this, the most common are:
Header redirect - this is where the browser is instructed to leave the
current url and move along to the new site, the url displayed in the address
bar is that of the new location.
the browser to leave the current url and move along to the new site, the url
displayed in the address bar is that of the new location. META refresh redirects
also include the option of a timed delay before the redirect takes place.
Frame/Stealth redirect - this is where frameset code is used which loads
the new location into a frame on the existing page. This page is normally configured
to be 100% so in effect it means the entire screen. This has the advantage that
the url displayed in the address bar remains that of the typed url.
An entity that offers registration services, usually within various tld's (extensions)
- examples include Enom and Network Solutions.
The controller of the tld's eg Verisign with .com

SLD - Second Level Domain
Reading from right to left, and splitting a domain into separate parts using
the dot as the delimiter, this is the second element e.g. in domain.com "domain"
is the sld, in bbc.co.uk the SLD is "co". Domain.com is said to be
a second level domain because the identifying element controlled by the registrant
is "domain", with the ".com" top level domain being controlled
by the registry.
TLD - Top Level Domain
Sometimes referred to as the "extension", this is the first element
of a domain name reading from right to left before the first dot e.g. in domain.com
the tld is .com. These are further broker down into gtld's which are generic
top level domains such as .com /.info etc which do not have a geographical association
and cctld's which are country code top level domains such as .uk/.de which do
have a geographical tie and are usually operated by agencies within the country
TM - TRADEMARK
From the UK Patent Office: "A trade mark is any sign which can distinguish
the goods and services of one trader from those of another. A sign includes,
for example, words, logos, pictures, or a combination of these. Basically, a
trade mark is a badge of origin, used so that customers can recognise the product
of a particular trader."
Trademarks can be registered with a trademark office or they can be common
law where the usage as a source of origin alone can create rights. Trademark
strength is on a sliding scale with descriptive/suggestive at one end and coined/fanciful/proprietary
at the other. Trademarks are not intended to provide ownership amd prevent third
party usage of a descriptive term in a descriptive capacity. Trademarks are
registered in classes (categories) and with geographic offices, although these
factors are not always included in dispute resolutions. Links: US
Patent and Trademark Office and UK
Again from the UK PTO: "Why shouldn't my trade mark be descriptive?
You cannot use everyday words which say what your goods or services are, as
everybody dealing in them should be able to use these words for their goods

Where a person enters an incorrect term/address usually through incorrect spelling.
UDRP - Uniform Domain Name Dispute Resolution Policy (Most gTld's like .com)
Dispute service that most gtld's (e.g. .com) are subject to. Remedy if found
against the domain holder is the transfer of the domain name. There are several
forums that offer UDRP services, WIPO and National Arbitration Forum being 2

Applicable Disputes. You are required to submit to a mandatory administrative
proceeding in the event that a third party (a "complainant") asserts
to the applicable Provider, in compliance with the Rules of Procedure, that
(i) your domain name is identical or confusingly similar to a trademark or
service mark in which the complainant has rights; and
(ii) you have no rights or legitimate interests in respect of the domain name;

to the web server via the DNS. Common web servers include Apache and Microsoft
This is where the domain is configured to resolve anything.domain.tld
rather than the traditional www.domain.tld and just domain.tld. The configuration
is performed in the nameserver that has authority for the domain name and the
web server also needs to be configured to accept the full domain when the data
is resolved to it for correct functionality.
This is another tool like KeywordDiscovery.com to look at the volume of searches a term has had from the Infospace search engine - the site is www.wordtracker.com
