Third generation mobile telephony, see UMTS.
802.11 is a wireless standard for connecting PCs together
to create a LAN referred to as Wi-Fi. The first version of Wi-Fi
was 802.11b, followed by the faster 802.11g. Wi-Fi provides
connection speeds comparable to Ethernet networks, but
without the cables. 802.11x is a method of referring
to the general 802.11 standard, and is not a specific variety. 802.11x is regulated by the IEEE (
A form of conjoint analysis developed by Sawtooth Software
where the program determines which conjoint task to ask next, based on the
respondent’s earlier responses. There is a version of ACA which is available
for Internet surveys, and which can be used in conjunction with Hierarchical Bayes. For more information
see www.sawtoothsoftware.com. ACA
is an example of a form of adaptive scripting.
See panels.
Acrobat Reader is a piece of software, which allows users
to read PDF files. Acrobat Reader is
produced by Adobe and can be downloaded free from www.adobe.com.
ActiveX is Microsoft’s answer to
Java; it is a programming language that can be used to
write small programs (applets) that perform a specific
task. The main drawback to ActiveX for Internet is that it requires the server
to be running Microsoft tools and for the browser to be capable of working with
it. More information about ActiveX can be found at www.microsoft.com.
An ad blocker is a piece of software that works with the users browser to prevent online advertisements being
displayed. Ad blockers can have the side effect of blocking other events as
well.
An ad click is a measure of the number of users
interacting with an ad. The most important type of ad click is the click-through.
The ad click rate is the ratio of ad
clicks to ad impressions, ie the number of
people who interacted with the ad as a percentage of all those who saw it.
An ad impression is created every time an ad is displayed
on a Web page. There are two categories of ad impression, push
and pull. Ads that are requested by the user’s browser are pull ads. Ads that
are initiated by the server are push ads.
An ad network is a broker of advertising space for a
number of different sites. These brokers act as the sales representatives for
the Web sites within the network.
Ad recall is a term used to describe the percentage of a
sample that can recall seeing an ad, after being exposed to it.
There are a number of variations that affect the recall
scores. The recall question is often asked immediately after the ad is removed
from the screen, but it may be asked later – the later the question is asked
the lower the recall is likely to be and the more likely that other chances to
see the ad will effect the score.
The recall question can be asked unprompted or as aided
recall. With aided recall the respondent is told the category, or brand, or
shown a copy of the ad (these are also known as prompted recall).
Ad rotation is when ads are rotated into an ad space from a list, either from the server
or via an ad server.
Most pages that display ads do not have the ad coded
directly into them, what they have are one or more ad
spaces where an ad server can send the ad to be displayed. An ad server
selects ads and sends them to the Web page when a request is received.
Ad serving is the delivery of an ad by the ad server to the user’s computer. The ad serving is
usually performed either by the publisher of the web site or by a third-party ad server.
An ad space is the location on the page where an ad is
going to be placed. There can be multiple ad spaces on a single page. An ad
space group is a number of ad spaces on the same page that share the same
characteristics and can be purchased as a group.
The collection of ads displayed to the user during a visit
to a site.
An ad view is created only when an ad is actually seen by
a user, this is not measurable with current technologies. Ad impressions may be off the visible screen,
partially loaded, blocked, or otherwise not viewed.
Adaptive scripting is a generic term for questionnaires
that are tailored to individual respondents. For example adaptive scripting can
be used to detect fraudulent responses, to shorten interviews for slower respondents, or to probe deeper when specific responses are
identified.
Adobe is a software company with a wide range of leading
programs including: Acrobat, Flash,
Dreamweaver, Photoshop, and Cold Fusion.
ADSL provides high bandwidth
Internet access using an ordinary telephone line. ADSL splits the telephone
line into two channels; this allows users to make normal telephone calls whilst
using the Internet. ADSL is one form of DSL
and is a type of broadband connection.
Affiliate marketing is an arrangement where one site (the
affiliate) carries ads for a second site and receives some form of
compensation, such as a percentage of the sales generated from the visits to
the second site.
Selling services and/or products to existing customers on
the basis of their buying/viewing/searching patterns.
An animated ad is an ad that changes. This can be
achieved, for example, by using streamed media, Shockwave, Java applets, or
animated GIFs.
See GIF.
An anonymizer is service that
prevents Web sites from detecting the user’s IP address. For more information
on one provider of these services see www.anonymizer.com.
Viruses are a major problem for
computers connected to the Internet. Antivirus software, software that searches
for and deals with viruses, has become an essential part of any system
configuration. The safest approach to virus protection is to use a program that
searches the Internet for updates on a regular basis. For information on a
leading provider of antivirus software visit www.norton.com.
AOL is the leading provider of consumer online services in
the
An applet is small self-contained piece of software that
can be sent along with a Web page to the users browser
to perform local processing. Applets are usually written in Java
and their uses include: interactive animations, immediate calculations, and the
implementation of a market research questionnaire. One problem with applet’s is
that they require the user to be running a compatible browser and also for the
user not to have blocked that type of applet.
The ARF is a USA-based non-profit trade association whose
mission is to improve the practice of advertising, marketing
and media research in pursuit of more effective marketing and advertising
communications. For more information visit www.arfsite.org.
ASCII is a method of representing Western character sets
using just a single byte. The standard form of ASCII uses
just 7 bits of the byte, meaning that just 128 characters are defined. It is
generally assumed that Unicode, a system which has the
disadvantage of using two bytes per character but which can represent over
65,000 characters, will replace ASCII over the next few years.
Active Server Pages is a proprietary technique designed by
Microsoft that allows a Web page to have a high
degree of interactivity without resorting to CGI scripting.
However Application Server Pages will only run if your server is using the
appropriate Microsoft software, eg it will not run if your server is Unix based.
This type of ASP is not particularly relevant to the world
of market research and should not be confused with Application Service Providers (also
referred to as ASPs), which are very important in the provision of market research
online services.
An ASP is a company that hosts applications on its servers and rents access to them over the Internet. Rather
than buy the software the subscribers use the systems on demand and tend to pay
on a per use basis. Within the world of market research two ASP products are Confirmit and GMI.
The term asynchronous research covers techniques that
allow respondents to answer in their own time rather than in direct response to
a question or prompt. Many quantitative techniques have this property, for
example mail, email, and diary. Until recently qualitative techniques tended to
be synchronous in nature, but the growth of Moderated
Email Groups and Bulletin Board Groups
has changed that.
Asynchronous qualitative is a term that includes those
forms of qualitative that do not require the moderator and the subject to be
interacting at the same time. Examples of asynchronous techniques include Blog
Groups, MEGs and Bulletin Board Groups.
B2B is a generic phrase for markets where the customers
for the products and services are companies rather than consumers. B2B market
research is conducted amongst those businesses that are customers or
prospective customers of the research agencies client.
B2C is a generic phrase to describe selling things to
consumers. B2C marker research in conducted with consumers.
B2B exchanges are online market places. Exchanges can take
a variety of forms including: providers offering products/services at a
specific price, providers offering products/services via an auction, buyers
requesting products/services via tender or competitive bid. B2B exchanges have
been most successful where they have been dealing with commodities that can be
readily interchanged, for example motor parts. However, many analysts predict
that in the future they will encompass a wider range of services, possibly
including market research fieldwork.
A backbone is central network connecting other networks
together. Networks within companies will often have a backbone connecting
smaller networks together. Likewise, the Internet has a backbone connecting
countries and major sites together.
Bandwidth describes the amount of electronic
"space" available on a computer network. Bandwidth is usually
expressed in bytes per second. A 56kbps modem, for
example, can transmit data at the rate of 56,000 bytes per second.
A banner is an advert that is displayed with a Web page. The
Web site’s publisher can serve banners or they can be organised and delivered
by ad-serving companies, such as Double-Click. More information on the
different formats of banners is available from www.iab.net,
the Interactive Advertising Bureau.
See Web bug.
Bit rate is a measure of bandwidth
that tells you how fast data is moving from one place to another. A bit is a
single unit of data (a 1 or a 0) and be expressed as Kbps (Kilobits per
second).
The term black-box is a pejorative description of a
proprietary system, where the owner of the system chooses to keep important
information secret. The term black-box can be applied to either the algorithm
(as in the case of a market modeling system), or to
the data format (ensuring that other vendors cannot supply additional or
competitive functionality).
A typical blog is defined by the software it is written in.
Blog software makes it very easy to add articles, either from a web interface,
or remotely using email or even mobile phone. Articles written for a blog are
called a post and are typically displayed in date order. Many blogs are set up
as a diary, either as a personal diary or about events in some area of interest.
Another common type of blog is the journalist blog, or the private citizen
engaging in their own journalism. Blogs are an example of Consumer
Generated Media.
Blog groups use blogs as a medium for
online asynchronous qualitative
research. In a typical project a group of members are recruited and given
access to a closed blog, one where the general public cannot access. A typical
project lasts one to two weeks, with about 10 participants. Each day the
moderator will post comments and often tasks for the group's members. The
members post their replies, often uploading material they have found on the web.
In many ways the Blog Group is very similar to the Bulletin
Board Group, but it has a more modern feel and corresponds with the growing
demand to let consumers have more say in their own terms.
The blogosphere is a collective term for all the blogs, rss
feeds, and discussions about blogs that are on the Internet.
Bluetooth is a protocol that
enables mobile and fixed-location devices to communicate via short-range
wireless connections. For example Bluetooth can be used to enable a mobile to
have an earpiece that is not connected by a cable. The aim of Bluetooth
proponents is to link together a wide variety of IT devices, including mobile
phones, PCs, PDAs, payment systems, and entertainments centers. However, Bluetooth has taken off much more slowly
than was expected and is being challenged by the uptake of systems such as 802.11b. For more information visit www.bluetooth.com.
Web browsers usually include a facility to ‘Bookmark’ a URL for future reference, ie storing the
location so the user can readily find it next time. Microsoft’s
Internet Explorer uses the terms Favorites to
describe the book marking process.
See Robot
When an email is undeliverable it will generally be sent
back to the sender with a message that it has not been delivered, this is a
bounce-back.
Brand Impact is Millward Brown’s proprietary technique for
measuring the effectiveness of online advertising.
A bricks and mortar company is a traditional business that
only has real locations with real customers coming through its doors. A company
that operates both online and offline is often referred to as a clicks and
mortar company. Companies that operate only on the Internet are referred to as pure plays.
A high speed Internet connection, any bit rate over
100Kbps is considered broadband. Cable modems, ADSL, and ISDN offer broadband to the home user.
A system used by streamed media
providers to ensure the smooth delivery of the media. The software loads an
amount of the stream into a buffer before starting to display the media; it can
then use this buffer to compensate for variations in download speed during the
session.
Bulletin Board Groups are an online qualitative approach
that uses a bulleting board to provide a means to communicating with the group
members. The moderator posts questions online or sets tasks (eg to visit a site
or to view some stimuli) and the members of the group log in at their
convenience to reply to the prompts and to other members’ responses. A Bulletin
Board Group is an example if an asynchronous
qualitative technique. Software for Bulletin Board Groups is available from
Itracks and GMI.
In the context of a Web page, a button is either a
clickable graphic with some functionality, or a form of online ad.
The byte is main unit of data in most modern computers. A
byte is holds 8 bits (1s or 0s) and can represent a number in the range 0 to
255. Bytes can be combined together to represent larger numbers, decimal
numbers, of executable code. In ASCII
one byte us used to store one character.
A cable modem is piece of hardware that allows a PC to
connect to the Internet over a cable network (such as a cable TV system). Cable
modems typically deliver high-speed access, ie they are a broadband connection.
A cache (pronounced cash) is an area that is used to
temporarily store information, particularly frequently used information. PCs
will usually use both RAM and hard disk caching to improve performance. Web
browsers write most of the information viewed to a cache, which speeds up
re-viewing the same material.
CAWI refers to interviewing over the Web as opposed to
CAPI (Computer Aided Personal Interviewing), CATI (Computer Aided Telephone
Interviewing), and PAPI (Paper and Pencil Interviewing). The term CAWI has a
somewhat old fashioned feel to it (very 90s).
CGI is a language that runs on a server
and which processes responses from the user. CGI can be used to take actions
based on the respondent’s responses to items on the page, such as check boxes. The
strength of CGI is that it since it runs on the server, rather than via the users browser (which is what languages like Java
do), it is more reliable. The disadvantages include the latency
in waiting for the server to respond, difficulties with the language, and
problems with obtaining permission to load the CGI programs onto the server.
Consumer Generated Media (also known as Participatory
Media) is a collective term for the many ways that people can express themselves
on the Web. These forms include: blogs, discussion forums,
product review sites, places where video clips can be uploaded such www.youtube.com
and personal spaces such as www.myspace.com.
Another aspect of CGM is the way that regular news channels such as the BBC
encourage people to send in video clips, using their mobile phones, from real
news stories, as they are breaking.
Chat is a facility for two or more people to communicate
on the Internet using real-time text. Chat tends to be divided into chat rooms and Instant
Messaging.
A chat room is Web location where two or more people can
chat together. Chat rooms can either be public (anybody can join them) or
private (typically locked via a password). Many chat rooms exist on a permanent
basis, either to discuss a particular topic, or as a general place to meet. A
chat room may be moderated.
Click rate is a measurement of the number of people
clicking on an ad, as a percentage of all those seeing the ad.
The click stream is the collection of data defining the
sequence of signals between a browser and the Internet. It is the combination
of the messages sent from the user to the server, and
the messages to the user.
When somebody clicks on a hyperlink (eg a banner) they
create a click-through. For some types of advertising the click-through seen as
the most important measure of its success, inasmuch as eyeballs have been
delivered. However, for most online ads it is more important to understand the
impact of the ad on the brand and/or the ads performance at delivering
completes (eg how many clicks lead to a purchase or a registration).
The click-through rate is the percentage of people who see
an ad and who then click on it. Some online advertising is priced on a how many
people click on an ad; see cost per click.
A clicks and mortar company is one that operates via
traditional real locations and via an Internet presence. An e-tailer is a clicks and mortar if it has both real and
virtual locations, but it is a so-called pure play if
it only has an online presence. The term clicks and mortar is an evolved form
of bricks and mortar, a term that refers to
companies that only have real locations.
The client is the computer that is connected to the
Internet and which sends information and requests to the server,
ie it is the user’s computer. Processing which takes place on the user’s
computer is referred to as client-side processing,
processing that takes place on the server is called server-side processing.
Codec stands for compression/decompression. Codecs are algorithms for compressing the size of media
files, making them easier to transmit over the Web. A file can only be read
using the same Codec that originally compressed it.
See CGM.
Content integration refers to advertising that in
integrated with the contents of a Web page, as opposed to having the
advertising clearly separated. Content integration can also be known as Web
advertorial.
A cookie is a file that the server
puts on the user’s browser, which uniquely identifies the user’s computer. There
are two types of cookies: persistent cookies and session cookies. Session
cookies are temporary and are erased when the session ends. Persistent cookies
remain on the user’s hard drive until the user erases them or until they
expire.
As a method of uniquely identifying people cookies have
their limitations. Firstly, a small number of people set their browser to
reject cookies. More importantly, using cookies to filter respondents assumes
that each person has only on computer and that each computer has only one user.
These problems do not invalidate cookies as a tool for the market researcher,
but they do make them a little fuzzy.
Cookies are currently the subject of substantial debate
with the European Union and their use is likely to be heavily regulated in the
near future.
Confirmit is the online market research service provided
by Norwegian company, Firm. Confirmit is an example of a
service being provided as by an ASP.
Convergence is a term that describes the coming together
of different technologies. For example the convergence of computer and
telephone networks means that voice and data calls can be carried on a single
network.
A
COPPR is a set of rules published by the United States FTC
in 1999 and which went into effect in the
Cost of advertising based on some agreed actions, for
example registering for a service or completing on online survey.
CPC is a pricing method for advertising based on charging
for each user who clicks on the advert.
Cost of advertising based on charges for units of
thousands ad impressions, this is the most common and traditional way of
pricing online advertising.
See Robot.
The ultimate aim of CRM is to identify and develop those
customers that will be most profitable to the company in the long-term. CRM
requires organizations to know about their individual customers, to track their
relationship, and to organize their activities is a targeted way.
Dark wire is the term applied to fiber
optic cable which is sold as unused capacity, for example a cable provider may
sell dark wire to a telco to allow them to use it for
their services.
Data Protection usually refers to national and
international legislation covering data privacy and the requirements on
organisations to handle personal information in a safe and proper manner. In
addition, many organizations issue guidelines that cover the area of Data
Protection/privacy, such as the ESOMAR/ARF
guidelines.
The DDA is a piece of UK legislation that requires services
to the public to be accessible to those with special needs, for example the
visually impaired. This law, and similar laws in other markets such as Australia
and USA, apply to publicly accessible websites and surveys that the public can
access. The best source of information on how to make websites accessible is
from the Web Accessibility Initiative at www.w3.org/WAI/.
DHTML is an extension to HTML
to add animation to Web pages.
Digital signatures provide a way of authenticating who has
sent an email or electronic document. Since digital signatures establish
identity, they can be used to legally endorse agreements and contracts.
In Discrete Choice respondents are given tasks where they
are offered choices and where they must pick one, as opposed to rank or rate
choices. The main use of Discrete Choice Models is in conjoint analysis, but
they can also be used in areas such as MaxDiff scaling
and Brand Price Trade-Off.
A name that represents an IP
address. Domain names are used to make IP addresses more friendly and
informative. In the following URL, ”http://www.thefutureplace.com/about.htm”,
the domain name is “thefutureplace.com”.
Characters are represented on computers, and on the
Internet, via numbers stored in binary format, ie 1s and 0s. For Western
character sets (eg the Roman character set), the characters can be represented
using a single byte (representing numbers in the range 0
to 255). The standard system for representing Western characters is ASCII and is well established.
However, some scripts require much more variation than can
be provided by ASCII. For example, Chinese has over 2000 different symbols. Computer
systems can be updated to use two bytes to represent each character (two bytes
provide over 65000 possible characters). The most common method for using two
bytes to represent characters is Unicode.
DSL is a method of sending high-speed data over a
conventional telephone line. DSL uses separate channels for voice and data, so
the user can talk on the same line they are using to connect to the Internet. DSL
comes in several varieties: The most common consumer variety is ADSL.
A dynamic IP address is an IP
address that changes every time that a user connects to the Internet. Dynamic
IPs are typical of users who
connect via ISPs and individuals within large corporations. Because many IP
addresses are dynamic they are not a reliable way of identifying repeat
visitors to a site.
The term eCRM is applied to both
CRM being applied to customers of
online companies and to the use of the Internet as part of a conventional
organization's CRM programme.
Encryption is a method of making it difficult or
impossible for third parties to read information or data. The original data is
scrambled using mathematical techniques before being stored or transmitted; it
is then decrypted when it is retrieved/received.
EDI is a well-established form of electronic commerce that
has traditionally taken place over proprietary networks. One way of reducing
the cost of EDI, and making it more accessible to smaller companies, is to migrate EDI standards to the Internet, various systems are
currently competing to offer this service.
ESOMAR is the European based international association of
market researchers. Amongst many other activities, ESOMAR issues guidelines on
the conduct of market research, and these guidelines are binding on it members.
These guidelines include sections on using the Internet for market research. Its
website is www.esomar.org.
The most important guidelines for researchers using the
Internet are those provided by ESOMAR. These rules include guidance on
providing Privacy Policies, of the special rules
for interviewing children, and the need to avoid spam. The
guidelines can be downloaded from www.esomar.org.
An e-tailer is simply an online
retailer. Traditional retailers are described as bricks
and mortar, whilst companies that embrace both traditional and electronic
channels are referred to as clicks and mortar.
An e-tailer that operates only online is known as a pure play company.
Ethernet is a method of networking computers together
within a site, ie a LAN.
An extranet is an area within an Intranet
that allows third parties to access specific information and resources. Extranets
are used both to share information with third parties and also to allow third
parties to deliver information and services.
Many Web sites and services have a FAQ section where users
can review the answers to typical questions. These FAQ’s can make the site more
usable and reduce the load on technical support teams.
A firewall is a technology that prevents unauthorized
access to areas of a network, and in particular which regulates people entering
private networks via the Internet, and prevents the admission of electronic
agents that could compromise your systems.

viewed by the same person. Cookies can be used to
control ad frequencies.
Freeware is software that is distributed free, often as an
inducement for people to try it and then to go on and buy a commercial version
(usually with greater functionality). Freeware should not be confused with shareware – for which some payment is usually required.
FTP is a method of uploading and downloading files. FTP
used to be fairly common on the Internet, but is now restricted mainly to the
technical community.
GIF is one of the two leading Internet formats for storing
graphical images, the other popular format being JPG. GIF files use data compression to
reduce the size of the file, making it easier to transmit over the Internet.
An animated GIF is created by storing multiple images in
the same file. These images are then displayed one after another giving the impression
of movement – in the same way a cartoon gives the image of movement.
GMI is a
Seth Godin is a leading author
and write on permission based marketing.

GPRS is often referred to as 2.5G (ie 2.5 generation)
because it is a way of improving the performance of the existing second-generation
mobile phone network. It can offer data rates between 56kbits/s and 114kbits/s.
GPRS allows users to remain connected to the Internet, being charged on the
volume of data sent and received, rather than by charging by connect time. GPRS
may provide a way of providing data communications prior to the introduction of
third generation mobile phone networks (UMTS)
in 2003.
GSM, or second generation mobile, is the current standard
for mobile telephony in
An alternative to the older text based interface. The most
typical GUI is the windows mouse pointer interface, which allows the user to
see the system as a sequence of icons and to use the mouse to control it.
Harris Interactive is a major
Hierarchical Bayes is a computer intensive technique that
is based on Bayesian statistics. The attraction of HB is that it allows a
researcher to collect sparse data and then estimate how the missing data would
behave. For example HB is used in conjoint analysis, each respondent answers a
sub-set of the questions and from this data a total distribution is estimated.
Using complicated procedures (beyond the scope of most researchers) HB then
estimates the values for each respondent.
TV using a digital format and providing about five times
as much definition as conventional TV.
A hit is the term used to describe each element downloaded
from the server when a user visits a web
page. If a page contains three graphical images then the server will record
fours hits, one for the page and one for each of the images downloaded. Hits
are useful as a measurement of workload on the server.
The home page is the central point of reference for a Web
site, and is often also known as the index page. Web sites tend to have a tree
structure, which starts with the home page and extends beyond it with a branch
structure. Many web sites will include links back to the home page at various
points, to enable the visitor to readily return to the central point.
A computer connected to the Internet offering services to
other computers. Each host has a permanent IP address.
A host is also known as a server.

House ads are ads for a product or service from the
company publishing the web page. The IAB
recommends that revenues from house ads should not be included in reported
advertising revenues.
HTML is the language that underpins World Wide Web. HTML allows browsers to convert
plain text Web pages into the graphical screens associated with the Internet. HTML
consists of a set of tags that tell the browser how to display the elements, or
where to download additional elements. HTML is a specific form of the more
general SGML.
HTTP is the most common format for transferring documents
on the Internet.
By convention URLs
that require SSL start with HTTPS, SSL provides a
secure Internet connection and is used when sensitive data, e.g. credit card
details, are being entered.
A hyperlink is a method of turning text or a graphic into
an instruction to transfer the user to some other locations (within a document
or across the Internet). The link is associated with a piece
of text or a graphic, when the users clicks on this
link they are taken to the new location.
The term hypertext refers to text on a page that causes a hyperlink to be actioned when
the user clicks on it.
A hyperstitial is an ad that is
displayed whilst the user waits for the requested page to be downloaded; these
ads can be full screen or smaller.
The IAB is a US based trade association (with other
national affiliates) who seeks to promote and regulate Internet advertising. For
more information see www.iab.net.
ICQ (pronounced I seek you) is the longest established
instant messaging system. In recent years MSN and AOL’s instant messaging have become more
popular.
A method of two or more people creating a private chat
room. IM systems (such as ICQ, AOL Instant Messaging etc) tell users which
of their friends/contacts are online.
An image map is a graphic on a Web page that comprises a
number of hyperlinks. Each hyperlink or hot spot can
lead to a different location. For example a store with regional outlets may
show a map of the country on its web site, where clicking on a region would
take the user to the information for that area.

An intranet is an internal computer network that uses
Internet technology to allow people within the organization to share
information and work collaboratively, ie a web within one company.
Inventory is an advertising term that covers the
collection of ads available on a Web site.
Invisible processing is a generic term that covers the
practice of collecting information about users/respondents without them
knowing. For example the server may query
the browser to find out client-side
information such as: screen size, operating system, color
settings, options enabled, plus server-side
information such as date of access, referring URL,
etc. The ESOMAR/ARF guidelines
say that a site’s Privacy Policy should warn
users if invisible processing is being used.
IP is the standard communications protocol
for transmitting data over the Internet. The reason the Internet works is that
everybody is using the same protocol.
