A quintessential index ofĀ key terminology, formulae, and digital advertising concepts for CMOs and seasoned marketing professionals. Did we forget something? Just use the form at the bottom of this page to let us know.
Advertising Effectiveness
Advertising Effectiveness considers how well advertising meets its goal(s). It's a concept that is studied heavily but poorly defined. After all, advertising goals may include ROAS, brand recall, sales lift, purchase intent, or many other things. Concluding (correctly) that advertising lacked a āuniversal definitionā and āshared languageā of effectiveness, in 2019, James Hurman and Peter Field conducted a global study of nearly 5,000 award entrant case studies from 2011 through 2019. The study analysed cases from the Cannes Creative Effectiveness Lions database (1,031 cases), WARCās database (3,616) and the IPA databank (216). The study concluded that marketing effectiveness is heavily impacted by media budget, duration and number of media channels applied, which are collectively referred to ācreative commitment.ā But above all, the study developed a cascading 'Creative Effectiveness Ladder' for defining outcomes correlated to effective advertising. In essence, advertising effectiveness can be defined as the following - with 1 being 'entry level' advertising effectiveness, and 6 being the 'holy grail' of effectiveness:
- Influential Idea: Advertising which over-achieves on campaign metrics.
- Behavioural Breakthrough: Advertising which changes consumer behaviour.
- Sales Spike: Advertising which delivers short-term, temporary sales growth.
- Brand Builder: Advertising which improves brand health.
- Commercial Triumph: Advertising which creates sustained sales success.1
- Enduring Icon: Advertising which creates long-term brand and sales growth.2

Contextual Keyword Advertising
A form of targeted advertising for advertisements appearing on websites or other media, such as content displayed in mobile browsers. The advertisements themselves are selected and served by automated systems based on the identity of the user and the content displayed.

Cost Per Thousand Impressions (CPM)
CPM is the the price (cost) per 1,000 impressions on a given media channel (digital, video/TV, OOH, or otherwise). It's the most common unit of price-based measurement in advertising, and the most universal as well. Radio, television, newspaper, magazine, out-of-home advertising, and online advertising can be purchased on the basis of showing the ad to one thousand viewers. Here's a calculator to get the CPM from the intended or quoted cost, and the impressions anticipated. Enjoy!
CPA (Cost Per Action)
Cost Per Action (CPA), also known as Pay Per Action (PPA) and Cost Per Conversion, is an online advertising pricing model where the advertiser pays for each specified action - for example, an impression, click, form submit, double opt-in or sale.
CPC (Cost Per Click)
Cost Per Click (CPC), also called Pay Per Click (PPC), is an internet advertising model used to direct traffic to websites, in which advertisers pay the publisher when the ad is clicked. It is defined simply as 'the amount spent to get an advertisement clicked.' To calculate CPC, divide the investment by the number of clicks achieved, or use our handy calculator:

Custom Audiences gives advertisers the ability reach their current customers + derivatives of those customers, via ads on Facebook, Instagram and Facebook's network.
DTC (Direct to Consumer)
Direct-to-Consumer Marketing takes brands directly to consumer when there might have previously been an intermediary - such as a retailer or traditional publisher. DTC brands are considered disruptive both for how they access their market - the logistics behind their offering - and their marketing strategy. Let's take a look at these two criteria:
Direct To Consumer Distribution: The First Frontier
Let's take a look at eyeglasses. In the past, the only way to get prescription glasses (in most Western markets) was to make an appointment to visit a doctor's office, pick out a pair of frames at that office, then wait a few weeks to pick up the glasses at the same optometrist's office. With the arrival of Warby Parker and others in the eyewear space, no more! Suddenly glasses could be delivered Direct To Consumer, with the doctor only involved for the eye exam. After a prescription is uploaded to the site, users can order their frames directly from the brand. Voila! Eyewear is shipped directly-to-consumer. Direct to Consumer distribution applies as well to industries of products traditionally sold on a B2B basis. A great, early example is domain registration. In the mid-90's, domains were the, well, domain of the few web developers in existence. It was a club of nerds, and a highly inaccessible process for the average person just signing on to their dial-up internet. Then came GoDaddy. In 2005, it ran a superbowl commercial offering its registration services, suddenly offering a niche product for the web developer subculture to the masses. This Direct To Consumer, approach was integral to GoDaddy's business plan, but also, later, its marketing. In advertising, DTC is often assumed to be pharma advertising. 'A 1996 marketing campaign for the allergy medicationĀ ClaritinĀ found a loophole by intentionally excluding information about the medication itself from its advertising (which only included imagery, slogans such as 'It's time for Claritin' and 'Clear days and nights are here', and instructions to ask a doctor or call a phone number to request more information).' This move led to a surge in pharma advertising, and ultimately the establishment of clearer guidelines for manufacturers to advertise directly to consumers, rather than just the B2B medical market. Media spending surged and DTC was born. Let's look at the second criterion for DTC, and the creation of 'Second Wave' DTC advertising:Direct To Consumer Marketing: The Second Wave
Before digital, consumer goods and media had a symbiotic relationship. The only way Johnson & Johnson could announce a new baby product was through TV airtime, print ads, billboards, radio spots and, well, advertising. And the only way media could monetize was through partners like J&J. While the latter is true, advertisers now control the game, with more avenues to reach consumers. DTC brands' signature move is using content, amplified via social media, to attract consumers in a nontraditional model.Recommended Reading:

DSP (Demand-side Platform)
A demand-side platform is software used to purchase advertising in an automated fashion from a variety of sources. Advertisers and agencies use DSPs to buy display, video, mobile, search, and increasingly OTT and even TV ads. DSPs help make the buying process cheaper and more efficient by purchasing media algorithmically across a wide variety of sources, theoretically in a more efficient way.
As an independent media buying agency, Criterion Global works with a variety of DSPs chosen according to client preference and needs. While there are risks with removing humans from parts of the equation, and certain limitations to what can be accomplished using DSPs (no Facebook, since Facebook 'sunsetted' FBX), DSPs are terrific for performance media buyingĀ as they help advertisers purchase inventory at scale.
Dynamic creative
Dynamic creative (personalized retargeting), allows an advertiser to display a banner created on-the-fly for a particular consumer based on specific pages that they viewed. For example, retargeting a consumer with a display banner featuring the exact products that they previously viewed from a specific website.
