[H] Interactive Marketing Glossary
HANDS FREE (Hands free kit ) – The operation of a mobile phone without the use of the handset; usually installed in vehicles and/or enabled via Bluetooth or similar headset.
HANDSET – Term used in reference to a mobile phone, mobile device, or mobile terminal.
HDTV (High-Definition Television) – a higher quality signal resolution using a digital format for the transmission and reception of TV signals. HDTV provides about five times more picture information (picture elements or pixels) than conventional television, creating clarity, wider aspect ratio, and digital quality sound.
HEAD END – the site in a cable system or broadband coaxial network where the programming originates and the distribution network starts. Signals are usually received off the air from satellites, microwave relays, or fiber-optic cables at the head end for distribution.
HEADING/H TAGS – This tag denotes a specific page or section heading on a Web page. Engines pay special attention to H text as it provides insight into the topicality and relevance of the content contained with the section.
HEURISTIC – a way to measure a user’s unique identity. This measure uses deduction or inference based on a rule or algorithm which is valid for that server. For example, the combination of IP address and user agent can be used to identify a user in some cases. If a server receives a new request from the same client within 30 minutes, it is inferred that a new request comes from the same user and the time since the last page request was spent viewing the last page. Also referred to as an inference.
HIGH SPEED DOWNLINK PACKET ACCESS – An enhancement to the Universal Mobile Telecommunications System (UMTS) 3G technology, also known as Wideband Code Division Multiple Access (W-CDMA). It is designed to increase the available download speeds by more than five times, and, in theory, reaches up to 14 Mbps (14 million bits per second).
HISTORY LIST – a menu in a web browser which displays recently visited sites. The same mechanism makes it possible for servers to track where a browser was before visiting a particular site.
HIT – 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, and 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 visitors and introduces the purpose of the site, or the organization sponsoring it, and then provides links to other pages within the site.
HOST – any computer on a network that offers services or connectivity to other computers on the network. A host has an IP address associated with it.
HOTLISTS – pull-down or pop-up menus often displayed on browsers or search engines that contain new or popular sites.
HOUSE ADS – ads for a product or service from the same company.
HTML (Hypertext Markup Language) – a set of codes called markup tags in a plain text file that determine what information is retrieved and how it is rendered by a browser. There are two kinds of markup tags: anchor and format. Anchor tags determine what is retrieved, and format tags determine how it is rendered. Browsers receive HTML pages from the Internet and use the information to display text, graphics, links and other elements as they were intended by a Website‘s creator.
HTTP (Hyper-Text Transfer Protocol) – the format most commonly used to transfer documents on the World Wide Web.
HYBRID PRICING – pricing model which is based on a combination of a CPM pricing model and a performance-based pricing model. See CPM pricing model and performance-based pricing model.
HYPERLINK – a clickable link, e.g., on a Web page or within an e-mail, that sends the user to a new URL when activated.
HYPERTEXT – any text that contains links connecting it with other text or files on the Internet.
