Usually, this will be 'index.­html', but on Windows IIS servers, it is often 'Default.­htm' or 'index.htm'. This information allows Google Analytics to reconcile log entries such as 'http://­www.­example.­com/' and 'http://­www.­example.­com/­index.­html', which are in fact the same page. Without the Default Page information entered correctly, these would be reported as two distinct pages. Only a single default page should be specified.

Delegation
The process of assigning name servers to a domain name.

Description
A short piece of descriptive text to describe a web page or website. With most search engines, they gain this information primarily from the meta data element of a web page. Directories approve or edit the description based on the submission that is made for a particular URL.

Frames
The use of multiple, independent sections to create a single Web page. Each frame is built as a separate HTML file but with one "master' file to identify each section. When a user requests a page with frames, several pages will be displayed as panes. Sites using frames may report one page request with several panes as multiple page requests. Most audit firms count only the master HTML page request and therefore can accurately report the page requests.

Gross Exposures
Each time a Web server sends a file to a browser, it is recorded in the server log file as a "hit." Hits are generated for every element of a requested page (including graphics, text and interactive items). If a page containing two graphics is viewed by a user, three hits will be recorded - one for the page itself and one for each graphic. Webmasters use hits to measure their server's work load. Because page designs vary greatly, hits are a poor guide for traffic measurement.

H

Hacker
Originally used to describe a computer enthusiast who pushed a system to its highest performance through clever programming.

Helper Application
This term refers to software programs that run along with browser programs enabling them to perform additional functions. Good examples are Shockwave for downloading and viewing moving images and Real Audio for hearing sounds and music online.

History List
Most browsers have a pull-down menu which displays the sites you've recently visited so you can return to site instantly or view your latest surfing session. The same mechanism makes it possible for servers to track where you were before visiting a particular site -- better viewing habit information than television networks ever dreamed of providing.

Hit
A hit is simply any request to the web server for any type of file. This can be an HTML page, an image (jpeg, gif, png, etc.), a sound clip, a cgi script, and many other file types. An HTML page can account for several hits: the page itself, each image on the page, and any embedded sound or video clips. Therefore, the number of hits a website receives is not a valid popularity gauge, but rather is an indication of server use and loading.

Home Page
The page designated as the main point of entry of a Web site (or main page) or the starting point when a browser first connects to the Internet. Typically, it welcomes you and introduces the purpose of the site, or the organization sponsoring it, and then provides links to the lower-level pages of the site. In business terms, it's the grabber. If your home page downloads too slowly, or it's unclear or unin­te­res­ting, you will probably lose a customer.

Host
An Internet host used to be a single machine connected to the Internet (which meant it had a unique IP address). As a host, it made available to other machines on the network certain services. However, virtual hosting has now meant that one physical host can now be actually many virtual hosts.

Hotlists
These can be pull-down or pop-up menus on browsers that contain new or popular sites. Major browser and search engine home pages also contain updated hotlists, and there are entire sites -- such as Cool Site O' the Day.

HTML
HyperText Markup Language is a coding language used to make hypertext documents for use on the Web. HTML resembles old-fashioned typesetting code, where a block of text is surrounded by codes that indicate how it should appear. HTML allows text to be "linked" to another file on the Internet.

Hypertext
Any text that that can be chosen by a reader and which causes another document to be retrieved and displayed.

HTTP
Hyper-Text Transfer Protocol, the format of the World Wide Web. When a browser sees "HTTP" at the beginning of an address, it knows that it is viewing a WWW page.

HTTPS
Hyper-Text Transfer Protocol Secure.

Hyperlink
This is the clickable link in text or graphics on a web page that takes you to another place on the same page, another page or a whole other site. It is the single most powerful and important function of online com­mu­nica­ti­ons. Hyperlinks are re­volu­ti­oni­zing the way the world gets its information.

Impression (Ad Impression or Page Impression)
The ad impression is the metric a site uses for measuring inventory. Different definitions exist for this term: 1. The viewing of a page or ad(s) by the user. The assumption is that the page or ad images were successfully downloaded and the user viewed the page or ads on the page are recorded whether or not a user clicks on an ad. 2.The request for a page or ad. Agencies usually collect a fee for every thousand impressions (hence the term CPM Ð cost per thousand).

Inbound Link
An inbound link is an hyperlink to a particular Web page from an outside site, bringing traffic to that Web page. Inbound links important because many search engine algorithms use the quality and quantity of inbound links to measure the popularity of a Web page.

Infopreneur
Someone who starts up a business in information technology or online commu­nica­ti­ons.

Inte­rac­tivity
If your web site isn't interactive, it's dead.

Internet
A collection of approxima­tely 60,000 independent, inter-connected networks that use the TCP/IP protocols and that evolved from ARPANet of the late '60s and early '70s. The Net," is a worldwide system of computer networks providing reliable and redundant connectivity between disparate computers and systems by using common transport and data protocols.

Internet Domain Name
The unique name that identifies an Internet entity.

Interstitial
Means "something in between" and is a page that is inserted in the normal flow of content between a user and a site. An Interstitial Ad is an "intrusive" ad unit that is spon­ta­ne­ous­ly delivered without specifically being requested by a user. Blocking the site behind it, Interstitial Ads are designed to grab consumers' attention for the few nanoseconds it takes them to close the window. In­ter­sti­ti­al's can be full pages or small daughter windows. Also referred to as "pop-ups."

Intranet
Intranets are private networks, usually maintained by corporations for internal com­mu­nica­ti­ons, which use Internet -- usually web -- protocols, software and servers. They are relatively cheap, fast, and reliable networking and information warehouse systems that link offices around the world. They make it is easy for corporate users to communicate with one another, and to access the information resources of the Internet.

IRC (Internet Relay Chat)
A facility that allows people -- from many different places in the world at one time -- to chat in real time. The chats, or forums, are typed remarks, and they can be either public or private. This, un­der­stan­dab­ly, is a wildly popular consumer area of the Internet. A sort of "ham radio" for the '90s, it offers intimacy combined with autonomy. Many celebrities are also talking to the public at pre-announced times, so IRC has commercial publicity uses, too. Business meetings can be conducted in the same way.

Inventory
The number of ads available for sale on a Web site. Ad inventory is determined by the number of ads on a page, the number of pages containing ad space and the number of page requests.

Invisible Web
A term that refers to the vast amount of information on the web that isn't indexed by search engines. Coined in 1994 by Dr. Jill Ellsworth.

IP address
Internet Protocol address. Every system connected to the Internet has a unique IP address, which consists of a number in the format A.B.C.D where each of the four sections is a decimal number from 0 to 255. Most people use Domain Names instead and the resolution between Domain Names and IP addresses is handled by the network and the Domain Name Servers. With virtual hosting, a single machine can act like multiple machines (with multiple domain names and IP addresses).

IP Delivery
To deliver content based on the IP address of the computer requesting the URL. Sometimes used to tailor content to different user groups.

ISDN (Integrated Digital Services Network)
ISDN lines are high-speed dial-up connections to the Internet. That's good. What's bad is that their cost and availability is determined by local telephone companies, which means in some places they are available, in other places not; and sometimes they're cheap, and at other times wildly expensive. It is a lot of commotion for a connection roughly four times faster -- 128,000 bits per second -- than a normal phone line. (The joke among com­mu­nica­ti­ons experts is that ISDN stands for "It Still Does Nothing.") Wait for fiber optic lines which will be thousands of times faster -- that's the future.

ISP (Internet Service Provider)
A business that provides access to the Internet. Its services are available to either individuals or companies, and include a dial-in interface with the Internet, software supply and often web site and intranet design. There are currently over 3,000 ISPs in the U.S. alone. It's a growth business, and as a result pricing is highly competitive, so shop around.

J

Java
Java is an object oriented programming language created by Sun Microsystems that supports enhanced features such as animation, or real-time updating of information. If you are using a web browser that supports Java, an applet (Java program) embedded in the Web page will auto­mati­cally run.

JPEG (Joint Photographic Experts Group)
JPEG (pronounced "jay peg") is a graphics format newer than GIF which displays photographs and graphic images with millions of colors, it also compresses well and is easy to download. Un­for­tuna­tely, not many browsers currently support it, so don't use it for your logo.

JS
Java Script

JSP
Java Server Pages (file.jsp)

K

Keyword
A word -- or often phrase -- used to focus an online search. A keyword is a database index entry that identifies a specific record or document. Keyword searching is the most common form of text search on the
