Common Web Development Terms
Ad banner -
a graphic image or other media object used as an advertisement. See iab.net for voluntary guidelines for banner ads.
Ad click -
a measurement of the user-initiated action of responding to (such as clicking on) an ad element causing a re-direct to another Web location or another frame or page within the advertisement. There are three types of ad clicks: 1) click-throughs; 2) in-unit clicks; and 3) mouseovers. Ad click-throughs should be tracked and reported as a 302 redirect at the ad server and should filter out robotic activity.
Ad click rate -
ratio of ad clicks to ad impressions.
a unique identifier for a computer or site online, usually a URL for a Web site or marked with an @ for an e-mail address. Literally, it is how one computer finds the location of another computer using the Internet.
Ad impression -
1) an ad which is served to a user's browser. Ads can be requested by the user's browser (referred to as pulled ads) or they can be pushed, such as e-mailed ads; 2) a measurement of responses from an ad delivery system to an ad request from the user's browser, which is filtered from robotic activity and is recorded at a point as late as possible in the process of delivery of the creative material to the user's browser -- therefore closest to the actual opportunity to see by the user. Two methods are used to deliver ad content to the user - a) server-initiated and b) client-initiated. Server-initiated ad counting uses the publisher's Web content server for making requests, formatting and re-directing content. Client-initiated ad counting relies on the user's browser to perform these activities.
For organizations that use a server-initiated ad counting method, counting should occur subsequent to the ad response at either the publisher's ad server or the Web content server. For organizations using a client-initiated ad counting method, counting should occur at the publisher's ad server or third-party ad server, subsequent to the ad request, or later, in the process. See iab.net for ad campaign measurement guidelines.
Ad network -
an aggregator or broker of advertising inventory for many sites. Ad networks are the sales representatives for the Web sites within the network.
Ad serving -
the delivery of ads by a server to an end user's computer on which the ads are then displayed by a browser and/or cached. Ad serving is normally performed either by a Web publisher, or by a third-party ad server. Ads can be embedded in the page or served separately.
Ad space -
the location on a page of a site in which an advertisement can be placed. Each space on a site is uniquely identified. Multiple ad spaces can exist on a single page.
the series of ads displayed by the user during a single visit to a site (also impression stream).
Ad window -
separate from the content window.
Alternate text -
a word or phrase that is displayed when a user has image loading disabled in their browser or when a user abandons a page by hitting "stop" in their browser prior to the transfer of all images. Also appears as "balloon text" when a user lets their mouse rest over an image.
Animated advertisement -
an ad that changes over time. For example, an animated ad is an interactive Java applet or Shockwave or GIF89a file.
Animated GIF -
an animation created by combining multiple GIF images in one file. The result is multiple images, displayed one after another, that give the appearance of movement.
makes web pages feel more responsive by exchanging small amounts of data with the server behind the scenes, so that the entire web page does not have to be reloaded each time the user makes a change.
a graphic image displayed on an HTML page used as an ad. See iab.net for voluntary guidelines defining specifications of banner ads.
Blogs Websites where entries are made in journal style,displayed in a reverse chronological order, and often include a comment feature.
memory used to temporarily store the most frequently requested content/files/pages in order to speed its delivery to the user. Cache can be local (i.e. on a browser) or on a network. In the case of local cache, most computers have both memory (RAM), and disk (hard drive) cache. Today, Web browsers cause virtually all data viewed to be cached on a user's computer.
Cache busting -
the process by which sites or servers serve content or HTML in such a manner as to minimize or prevent browsers or proxies from serving content from their cache. This forces the user or proxy to fetch a fresh copy for each request. Among other reasons, cache busting is used to provide a more accurate count of the number of requests from users.
Cached ad impressions -
the delivery of an advertisement to a browser from local cache or a proxy server's cache. When a user requests a page that contains a cached ad, the ad is obtained from the cache and displayed.
the process of copying a Web element (page or ad) for later reuse. On the Web, this copying is normally done in two places: in the user's browser and on proxy servers. When a user makes a request for a Web element, the browser looks into its own cache for the element; then a proxy, if any; followed by the intended server. Caching is done to reduce redundant network traffic, resulting in increased overall efficiency of the Internet.
CGI script (Common Gateway Interface) -
CGI's are used to allow a user to pass data to a Web server, most commonly in a Web-based form. Specifically, CGI scripts are used with forms such as pull-down menus or text-entry areas with an accompanying submit button. The input from the form is processed by a program (the CGI script itself) on a remote Web server.
1) a band of similar content; 2) a type of sales outlet (also known as channel of distribution), for example retail, catalogue, or e-commerce.
online interactive communication between two or more people on the Web. One can "talk" in real time with other people in a chat room, but the words are typed instead of spoken.
Chat room -
an area online where you can chat with other people in real-time.
Click down -
the action of clicking on an element within an ad and having another file displayed on the user's screen, normally below or above the initial ad. Click down ads allow the user to stay on the same Web page and provide the advertiser a larger pallet to communicate their message.
Click rate -
ratio of ad clicks to ad impressions.
1) metric which measures the reaction of a user to an Internet ad. There are three types of clicks: click-throughs; in-unit clicks; and mouseovers; 2) the opportunity for a user to download another file by clicking on an advertisement, as recorded by the server; 3) the result of a measurable interaction with an advertisement or key word that links to the advertiser's intended Web site or another page or frame within the Web site; 4) metric which measures the reaction of a user to hot-linked editorial content. See iab.net for ad campaign measurement guidelines. See also ad click, click-through, in-unit clicks and mouseover.
1) the electronic path a user takes while navigating from site to site, and from page to page within a site; 2) a comprehensive body of data describing the sequence of activity between a user's browser and any other Internet resource, such as a Web site or third party ad server.
the action of following a hyperlink within an advertisement or editorial content to another Web site or another page or frame within the Web site. Ad click-throughs should be tracked and reported as a 302 redirect at the ad server and should filter out robotic activity.
similar to click down or click. But more commonly, click-withins are ads that allow the user to "drill down" and click, while remaining in the advertisement, not leaving the site on which they are residing.
a computer that submits an information request to a server on behalf of a user or proxy.
Client-initiated ad impression -
one of the two methods used for ad counting. Ad content is delivered to the user via two methods - server-initiated and client-initiated. Client-initiated ad counting relies on the user's browser for making requests, formatting and re-directing content. For organizations using a client-initiated ad counting method, counting should occur at the publisher's ad server or third-party ad server, subsequent to the ad request, or later, in the process. See server-initiated ad impression.
Content integration -
advertising woven into editorial content or placed in a contextual envelope. Also known as "Web advertorial".
a file on the user's browser that uniquely identifies the user's browser. There are two types of cookies: persistent cookies and session cookies. Session cookies are temporary and are erased when the browser exits. Persistent cookies remain on the user's hard drive until the user erases them or until they expire.
Cookie buster -
software that blocks the placement of cookies on a user's browser.
COPPA (Children's Online Privacy Protection Act) -
Congress enacted the COPPA in 1998 to prohibit unfair or deceptive acts or
practices in connection with the collection, use, or disclosure of personally identifiable information from and about children on the Internet. Section 6502(b)(1) of the Act sets forth a series of general privacy protections to prevent unfair or deceptive online information collection from or about children, and directs the Commission to adopt regulations to implement those protections. The Act requires operators of Web sites directed to children and operators who knowingly collect personal information from children to: (1) Provide parents notice of their information practices; (2) obtain prior verifiable parental consent for the collection, use, and/or disclosure of personal information from children (with certain limited exceptions for the collection of "online contact information," e.g., an e-mail address); (3) provide a parent, upon request, with the means to review the personal information collected from his/her child; (4) provide a parent with the opportunity to prevent the further use of personal information that has already been collected, or the future collection of personal information from that child; (5) limit collection of personal information for a child's online participation in a game, prize offer, or other activity to information that is reasonably necessary for the activity; and (6) establish and maintain reasonable procedures to protect the confidentiality, security, and integrity of the personal information collected.
COPPR (Children's Online Privacy Protection Rule) -
issued by the FTC in October 1999 the Children's Online Privacy Protection Rule went into effect on April 21, 2000, and implements the requirements of the COPPA by requiring operators of websites or online services directed to children and operators of Web sites or online services who have actual knowledge that the person from whom they seek information is a child (1) to post prominent links on their Web sites to a notice of how they collect, use, and/or disclose personal information from children; (2) with certain exceptions, to notify parents that they wish to collect information from their children and obtain parental consent prior to collecting, using, and/or disclosing such information; (3) not to condition a child's participation in online activities on the provision of more personal information than is reasonably necessary to participate in the activity; (4) to allow parents the opportunity to review and/or have their children's information deleted from the operator's database and to prohibit further collection from the child; and (5) to establish procedures to protect the confidentiality, security, and integrity of personal information they collect from children. As directed by the COPPA, the Rule also provides a safe harbor for operators following Commission-approved self-regulatory guidelines. See www.caru.org for more information.

Daughter window -
an ad that runs in a separate ad window associated with a concurrently displayed banner. In normal practice, the content and banner are rendered first and the daughter window appears thereafter.
Domain name -
the unique name that identifies an Internet site. Every domain name consists of one top or high-level and one or more lower-level designators. Top-level domains (TLDs) are either generic or geographic. Generic top-level domains include .com (commercial), .net (network), .edu (educational), .org (organizational, public or non-commercial), .gov (governmental), .mil (military); .biz (business), .info (informational),.name (personal), .pro (professional), .aero (air transport and civil aviation), .coop (business cooperatives such as credit unions) and .museum. Geographic domains designate countries of origin, such as .us (United States), .fr (France), .uk (United Kingdom), etc.
Dynamic ad placement -
the process by which an ad is inserted into a page in response to a user's request. Dynamic ad placement allows alteration of specific ads placed on a page based on any data available to the placement program. At its simplest, dynamic ad placement allows for multiple ads to be rotated through one or more spaces. In more sophisticated examples, the ad placement could be affected by demographic data or usage history for the current user.
Dynamic IP address -
an IP address that changes every time a user logs on to the Internet.
Dynamic rotation -
delivery of ads on a rotating, random basis so that users are exposed to different ads and ads are served in different pages of the site.
E-mail campaign -
advertising campaign distributed via e-mail.
the process of compressing and separating a file into packets so that it can be delivered over a network.
a hardware or software application used to compress audio and video signals for the purpose of streaming.

Flash downloading -
the ability to automatically send software upgrades to a set-top box network.
Flash is commonly used to create animation, advertisements, various web-page components, to integrate video into web pages, and more recently, to develop rich Internet applications.
Floating ads -
an ad or ads that appear within the main browser window on top of the Web page's normal content, thereby appearing to "float" over the top of the page.
an ad or content that is viewable as soon as the Web page arrives. One does not have to scroll down (or sideways) to see it. Since screen resolution can affect what is immediately viewable, it is good to know whether the Web site's audience tends to set their resolution at 640 x 480 pixels or at 800 x 600 (or higher).
a facility on Web for holding discussions.
multiple, independent sections used to create a single Web page. Each frame is built as a separate HTML file but with one "master" file to control the placement of each section. When a user requests a page with frames, several files will be displayed as panes. Sites using frames report one page request with several panes as multiple page requests. IAB ad campaign measurement guidelines call for the counting of one file per frame set as a page impression.
Frame rate -
the number of frames of video displayed during a given time. The higher the frame rate, the more high-quality the image will be.
GIF (Graphic Interchange Format) -
a graphic format which uses compression to store and display images.
GIF89a/Animated GIF -
an extension of the .gif format which creates animation through a sequence of images being stored in a single image. A delay is customizable between "frames" to render the appearance of animation, much like a flappable picturebook.
Gross exposures -
the total number of times an ad is served, including duplicate downloads to the same person.
when users access a Web site, their computer sends a request to the site's server to begin downloading a page. Each element of a requested page (including graphics, text, interactive items) is recorded by the site's Web server log file as a "hit." If a page containing two graphics is accessed by a user, those hits will be recorded once for the page itself and once for each of the graphics. Webmasters use hits to measure their servers' workload. Because page designs and visit patterns vary from site to site, the number of hits bears no relationship to the number of pages downloaded, and is therefore a poor guide for traffic measurement.
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 other pages within the site.

1) time it takes for a data packet to move across a network connection; 2) visible delay between request and display of content and ad. Latency sometimes leads to the user leaving the site prior to the opportunity to see. In streaming media, latency can create stream degradation if it causes the packets, which must be received and played in order, to arrive out of order.

Search engine -
a program that helps Web users find information on the Internet. The method for finding this information is usually done by maintaining an index of Web resources that can be queried for the keywords or concepts entered by the user.
a computer which distributes files which are shared across a LAN, WAN or the Internet. Also known as a "host".
1) a sequence of Internet activity made by one user at one site. If a user makes no request from a site during a 30 minute period of time, the next content or ad request would then constitute the beginning of a new visit; 2) a series of transactions performed by a user that can be tracked across successive Web sites. For example, in a single session, a user may start on a publisher's Web site, click on an advertisement and then go to an advertiser's Web site and make a purchase. See visit.
Session cookies -

slang term describing unsolicited e-mail.
a program that automatically fetches Web pages. Spiders are used to feed pages to search engines. It is called a spider because it crawls over the Web. Because most Web pages contain links to other pages, a spider can start almost anywhere. As soon as it sees a link to another page, it goes off and fetches it. Large search engines have many spiders working in parallel. See robot.
Splash page -
a preliminary page that precedes the user-requested page of a Web site that usually promotes a particular site feature or provides advertising.
