Digital media glossaries include terms such as conversion, supply-side platform, ALT attribute, squidoo and cache busting. Conversion is when a user performs an online action, such as purchasing an item, which the advertiser tracks, while supply-side platform is a technology platform that allows publishers to manage their ad inventory while maximizing revenue. Squidoo refers to popular user-generated sites that allow users to create single-page websites on various topics.
An ALT attribute is a line of text that explains a non-text file, such as an image. Cache busting refers to forcing a user who has cached, which means to have saved a webpage or other content, to download a new copy of the same content rather than use the one previously cached. Publishers like cache busting because it provides more accurate information as to the number of users requesting their content.
Other digital media glossary terms include CTR, PPC, sphinn and VOIP. Glossaries describe CTR, which is the abbreviation for click-thru rate, as the percentage of people who click on a link, while PPC references the per-click payments that advertisers make to get the best placement (and most clicks) for their ads on various search-engine listings. A bidding process among advertisers determines which advertiser gets the placement and how much they pay per click. Sphinn, in digital media vernacular, refers to an online marketer's social-bookmarking site. VOIP is the acronym for "voice over Internet protocol," a technology that makes it possible for users to make phone and video calls via the Internet.
