Adware, often called advertising-supported software by its developers, is software that generates revenue for its developer by automatically generating online advertisements in the user interface of the software or on a screen presented to the user during the installation process. The software may generate two types of revenue: one is for the display of the advertisement and another on a "pay-per-click" basis, if the user clicks on the advertisement. Some advertisements also act as spyware, collecting and reporting data about the user, to be sold or used for targeted advertising or user profiling. The software may implement advertisements in a variety of ways, including a static box display, a banner display, full screen, a video, pop-up ad or in some other form. All forms of advertising carry health, ethical, privacy and security risks for users.
Claria Corporation was a software company based in Redwood City, California that invented “Behavioral Marketing”, a highly effective but controversial new form of online advertising. It was founded in 1998 by Denis Coleman, Stanford MBA Sasha Zorovic, and engineer Mark Pennell, based on work Zorovic had done at Stanford. In March 1999 Jeff McFadden was hired as CEO and Zorovic was effectively forced out.
Pop-up ads or pop-ups are forms of online advertising on the World Wide Web. A pop-up is a graphical user interface (GUI) display area, usually a small window, that suddenly appears in the foreground of the visual interface. The pop-up window containing an advertisement is usually generated by JavaScript that uses cross-site scripting (XSS), sometimes with a secondary payload that uses Adobe Flash. They can also be generated by other vulnerabilities/security holes in browser security.
Google AdSense is a program run by Google through which website publishers in the Google Network of content sites serve text, images, video, or interactive media advertisements that are targeted to the site content and audience. These advertisements are administered, sorted, and maintained by Google. They can generate revenue on either a per-click or per-impression basis. Google beta-tested a cost-per-action service, but discontinued it in October 2008 in favor of a DoubleClick offering. In Q1 2014, Google earned US$3.4 billion, or 22% of total revenue, through Google AdSense. AdSense is a participant in the AdChoices program, so AdSense ads typically include the triangle-shaped AdChoices icon. This program also operates on HTTP cookies. In 2021, over 38.3 million websites use AdSense.
Google Ads is an online advertising platform developed by Google, where advertisers bid to display brief advertisements, service offerings, product listings, or videos to web users. It can place ads both in the results of search engines like Google Search and on non-search websites, mobile apps, and videos. Services are offered under a pay-per-click (PPC) pricing model.
Ad blocking or ad filtering is a software capability for blocking or altering online advertising in a web browser, an application or a network. This may be done using browser extensions or other methods.
An online advertising network or ad network is a company that connects advertisers to websites that want to host advertisements. The key function of an ad network is an aggregation of ad supply from publishers and matching it with advertiser's demand. The phrase "ad network" by itself is media-neutral in the sense that there can be a "Television Ad Network" or a "Print Ad Network", but is increasingly used to mean "online ad network" as the effect of aggregation of publisher ad space and sale to advertisers is most commonly seen in the online space. The fundamental difference between traditional media ad networks and online ad networks is that online ad networks use a central ad server to deliver advertisements to consumers, which enables targeting, tracking and reporting of impressions in ways not possible with analog media alternatives.
Online advertising, also known as online marketing, Internet advertising, digital advertising or web advertising, is a form of marketing and advertising which uses the Internet to promote products and services to audiences and platform users. Online advertising includes email marketing, search engine marketing (SEM), social media marketing, many types of display advertising, and mobile advertising. Advertisements are increasingly being delivered via automated software systems operating across multiple websites, media services and platforms, known as programmatic advertising.
Google Analytics is a web analytics service offered by Google that tracks and reports website traffic, currently as a platform inside the Google Marketing Platform brand. Google launched the service in November 2005 after acquiring Urchin.
Zango,, formerly ePIPO, 180solutions and Hotbar, was a software company that provided users access to its partners' videos, games, tools and utilities in exchange for viewing targeted advertising placed on their computers. Zango software is listed as adware by Symantec, and is also labeled as a potentially unwanted program by McAfee. Zango was co-founded by two brothers: Keith Smith, who served as the CEO; and Ken Smith, who served as the CTO.
Privacy-invasive software is computer software that ignores users’ privacy and that is distributed with a specific intent, often of a commercial nature. Three typical examples of privacy-invasive software are adware, spyware and browser hijacking programs.
Targeted advertising is a form of advertising, including online advertising, that is directed towards an audience with certain traits, based on the product or person the advertiser is promoting. These traits can either be demographic with a focus on race, economic status, sex, age, generation, level of education, income level, and employment, or psychographic focused on the consumer values, personality, attitude, opinion, lifestyle and interest. This focus can also entail behavioral variables, such as browser history, purchase history, and other recent online activities. Targeted advertising is concentrated in certain traits and consumers who are likely to have a strong preference. These individuals will receive messages instead of those who have no interest and whose preferences do not match a particular product's attributes. This eliminates waste.
Behavioral retargeting is a form of online targeted advertising by which online advertising is targeted to consumers based on their previous internet behaviour. Retargeting tags online users by including a pixel within the target webpage or email, which sets a cookie in the user's browser. Once the cookie is set, the advertiser is able to show ads to that user elsewhere on the internet via an ad exchange.
Google Ad Manager is an ad exchange platform introduced by Google on June 27, 2018. It combines the features of two former services from Google's DoubleClick subsidiary, DoubleClick for Publishers and DoubleClick Ad Exchange (AdX). Google Ad Manager initially used a second-price auction format, before announcing that it would be replaced with a first-price auction format in March 2019. Google Ad Manager is the free version of this online ad management software and it is recommended for small businesses. Google Ad Manager 360 is the paid version. Google Ad Manager does not require a minimum amount of impressions on individual active ads, but it does have a limit of 200 million impressions per month. Google Ad Manager manages inventory for advertisers, publishers and ad servers. Advertisers are able to manage their inventory of ad creative, publishers are able to manage their ad space inventory, and ad servers can use the platform to determine which ad to serve and where to serve it. Additionally, Google Ad Manager can use data collected from ad performance and ad space performance to make suggested optimizations to the user. These optimizations suggest what the user could change to better reach the goals they have set for a particular campaign.
Malvertising is the use of online advertising to spread malware. It typically involves injecting malicious or malware-laden advertisements into legitimate online advertising networks and webpages. Online advertisements provide a solid platform for spreading malware because significant effort is put into them in order to attract users and sell or advertise the product. Because advertising content can be inserted into high-profile and reputable websites, malvertising provides malefactors an opportunity to push their attacks to web users who might not otherwise see the ads, due to firewalls, more safety precautions, or the like. Malvertising is "attractive to attackers because they 'can be easily spread across a large number of legitimate websites without directly compromising those websites'."
Real-time bidding (RTB) is a means by which advertising inventory is bought and sold on a per-impression basis, via instantaneous programmatic auction, similar to financial markets. With real-time bidding, advertising buyers bid on an impression and, if the bid is won, the buyer's ad is instantly displayed on the publisher's site. Real-time bidding lets advertisers manage and optimize ads from multiple ad-networks, allowing them to create and launch advertising campaigns, prioritize networks, and allocate percentages of unsold inventory, known as backfill.
Advertising revenue is the monetary income that individuals and businesses earn from displaying paid advertisements on their websites, social media channels, or other platforms surrounding their internet-based content. In September 2018, the U.S Internet advertising market was estimated to be worth $111 billion, with market share being held mostly between Google, Facebook, Amazon, and Microsoft. These companies earn revenue through online advertising but also have initiated pathways for individual users and social media "influencers" to earn an income. Individuals and businesses can earn advertising revenue through advertisement networks such as Google AdSense, YouTube monetization, or Outbrain.
Scroll is a web service developed by Scroll Labs Inc. that offers ad-free access to websites in exchange for a subscription fee. Scroll is not an ad blocker, but rather partners directly with internet publishers who voluntarily take down ads on their site for Scroll users in exchange for a portion of the subscription fee.
Federated Learning of Cohorts (FLoC) is a type of web tracking. It groups people into "cohorts" based on their browsing history for the purpose of interest-based advertising. FLoC was being developed as a part of Google's Privacy Sandbox initiative, which includes several other advertising-related technologies with bird-themed names. Despite "federated learning" in the name, FLoC does not utilize any federated learning.
The Privacy Sandbox is an initiative led by Google to create web standards for websites to access user information without compromising privacy. Its core purpose is to facilitate online advertising without the use of third-party cookies. The initiative includes Federated Learning of Cohorts as well as other proposed technologies, many of which have bird-themed names. It was announced in August 2019.
