Paxfire provides an appliance called the Paxfire Lookup Engines (PLE) to internet service providers (ISPs) as a method of generating additional revenue through advertising based on mistyped URLs. By using the Paxfire service, an ISP can redirect mistyped web queries from its clients to navigation pages that may contain paid advertising sources. If a user clicks on a sponsored link, Paxfire and the ISP share the revenue.
In 2011, a research team from the Berkeley-based International Computer Science Institute revealed that technology from Paxfire was also used by several US ISPs to redirect valid search engine queries for certain well-known brand names to an online marketing company. [2]
Paxfire customers are telephone and cable TV companies, and traditional ISPs both in the United States and other countries. [3] Paxfire is under non-disclosure agreements (NDAs) that prohibit[ citation needed ] the company from releasing a list of all participating ISPs. According to the Electronic Frontier Foundation, as of August 2011 "major users of the Paxfire system include Cavalier, Cogent, Frontier, Fuse, DirecPC, RCN, and Wide Open West." [4]
Paxfire's approach affects all of the end-user's transactions involving the domain name system (essentially all Internet application transactions) rather than just an end-user's web browser. The default behavior will automatically redirect mistyped web URLs to MSN Search. Paxfire's provides 2 methods to opt out of the service. The first method employs an HTTP Cookie and the second method employs IP address filtering at the Paxfire appliance. An ISP is free to make use of these methodologies to ensure that users can opt out, though the cookie method is irrelevant for non-web transactions like email. Security researcher Dan Kaminsky found serious vulnerabilities related to how Paxfire was handling DNS resolution. [5]
In August 2011, Paxfire and one of its ISP customers were sued for the hijacking and redirection of customers' valid search requests intended for Google, Bing, and Yahoo search engines. [2] The lawsuit alleges that results for searches of certain well-known brand names by consumers are not being provided by the intended search engine, and instead are being provided through affiliate marketing networks to earn revenue for Paxfire and the ISP. According to the New Scientist, this practice may be illegal under U.S. law. [2]
A class action lawsuit was quickly filed. Paxfire responded that the basis of the lawsuit was wrong, saying that it would seek sanctions against the lawyers for filing it in the first place. The company filed a countersuit against the law firm, Milberg LLP, as well as the individual, Betsy Feist, who, as a client of Milberg, was the person who initiated the attempted class action lawsuit. Paxfire charged both defamation and tortious interference, demanding $50 million.
In recent movements the company finds itself in a dire financial situation, and with its ads feed cut off from all its suppliers. Recently all direct numbers have been found not working and speculation states that they have closed their support office and are contracting a third party to handle it.[ clarification needed ]
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. In 2021, more than 38 million websites used AdSense. It is a participant in the AdChoices program, so AdSense ads typically include the triangle-shaped AdChoices icon. This program also operates on HTTP cookies.
Google Ads is an online advertising platform developed by Google, where advertisers bid to display brief advertisements, service offerings, product listings, and videos to web users. It can place ads in the results of search engines like Google Search, mobile apps, videos, and on non-search websites. Services are offered under a pay-per-click (PPC) pricing model.
Click fraud is a type of fraud that occurs on the Internet in pay per click (PPC) online advertising. In this type of advertising, the owners of websites that post the ads are paid based on how many site visitors click on the ads. Fraud occurs when a person, automated script, computer program or an auto clicker imitates a legitimate user of a web browser, clicking on such an ad without having an actual interest in the target of the ad's link in order to increase revenue. Click fraud is the subject of some controversy and increasing litigation due to the advertising networks being a key beneficiary of the fraud.
Internet privacy involves the right or mandate of personal privacy concerning the storage, re-purposing, provision to third parties, and display of information pertaining to oneself via the Internet. Internet privacy is a subset of data privacy. Privacy concerns have been articulated from the beginnings of large-scale computer sharing and especially relate to mass surveillance.

Web analytics is the measurement, collection, analysis, and reporting of web data to understand and optimize web usage. Web analytics is not just a process for measuring web traffic but can be used as a tool for business and market research and assess and improve website effectiveness. Web analytics applications can also help companies measure the results of traditional print or broadcast advertising campaigns. It can be used to estimate how traffic to a website changes after launching a new advertising campaign. Web analytics provides information about the number of visitors to a website and the number of page views, or creates user behavior profiles. It helps gauge traffic and popularity trends, which is useful for market research.
Browser hijacking is a form of unwanted software that modifies a web browser's settings without a user's permission, to inject unwanted advertising into the user's browser. A browser hijacker may replace the existing home page, error page, or search engine with its own. These are generally used to force hits to a particular website, increasing its advertising revenue.

In August 2010, Intertrust Technologies announced that it had acquired all software and patents developed by SeeqPod, Inc. via the Chapter 7 Bankruptcy proceeding. Intertrust did not acquire the domain names used by the company.
DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. This can be achieved by malware that overrides a computer's TCP/IP configuration to point at a rogue DNS server under the control of an attacker, or through modifying the behaviour of a trusted DNS server so that it does not comply with internet standards.
NebuAd was an American online advertising company based in Redwood City, California, with offices in New York and London and was funded by the investment companies Sierra Ventures and Menlo Ventures. It was one of several companies which originally developed behavioral targeting advertising systems, and sought deals with ISPs to enable them to analyse customer's websurfing habits in order to provide them with more relevant, micro-targeted advertising. Phorm was a similar company operating out of Europe. Adzilla and Project Rialto also appear to be developing similar systems.
An ISP redirect page is a spoof page served by major ISPs including: Cox Communications, Embarq, Verizon, Rogers, Earthlink, and various others when World Wide Web users enter an invalid DNS name.
Scour Inc. was a multimedia Internet search engine, and provided Scour Exchange, an early peer-to-peer file exchange service.
Web tracking is the practice by which operators of websites and third parties collect, store and share information about visitors' activities on the World Wide Web. Analysis of a user's behaviour may be used to provide content that enables the operator to infer their preferences and may be of interest to various parties, such as advertisers. Web tracking can be part of visitor management.
A potentially unwanted program (PUP) or potentially unwanted application (PUA) is software that a user may perceive as unwanted or unnecessary. It is used as a subjective tagging criterion by security and parental control products. Such software may use an implementation that can compromise privacy or weaken the computer's security. Companies often bundle a wanted program download with a wrapper application and may offer to install an unwanted application, and in some cases without providing a clear opt-out method. Antivirus companies define the software bundled as potentially unwanted programs which can include software that displays intrusive advertising (adware), or tracks the user's Internet usage to sell information to advertisers (spyware), injects its own advertising into web pages that a user looks at, or uses premium SMS services to rack up charges for the user. A growing number of open-source software projects have expressed dismay at third-party websites wrapping their downloads with unwanted bundles, without the project's knowledge or consent. Nearly every third-party free download site bundles their downloads with potentially unwanted software. The practice is widely considered unethical because it violates the security interests of users without their informed consent. Some unwanted software bundles install a root certificate on a user's device, which allows hackers to intercept private data such as banking details, without a browser giving security warnings. The United States Department of Homeland Security has advised removing an insecure root certificate, because they make computers vulnerable to serious cyberattacks. Software developers and security experts recommend that people always download the latest version from the official project website, or a trusted package manager or app store.
Google's changes to its privacy policy on March 16, 2012, enabled the company to share data across a wide variety of services. These embedded services include millions of third-party websites that use AdSense and Analytics. The policy was widely criticized for creating an environment that discourages Internet innovation by making Internet users more fearful and wary of what they do online.
The commercialization of the Internet encompasses the creation and management of online services principally for financial gain. It typically involves the increasing monetization of network services and consumer products mediated through the varied use of Internet technologies. Common forms of Internet commercialization include e-commerce, electronic money, and advanced marketing techniques including personalized and targeted advertising. The effects of the commercialization of the Internet are controversial, with benefits that simplify daily life and repercussions that challenge personal freedoms, including surveillance capitalism and data tracking. This began with the National Science Foundation funding supercomputing center and then universities being able to develop supercomputer sites for research and academic purposes.
Search engine privacy is a subset of internet privacy that deals with user data being collected by search engines. Both types of privacy fall under the umbrella of information privacy. Privacy concerns regarding search engines can take many forms, such as the ability for search engines to log individual search queries, browsing history, IP addresses, and cookies of users, and conducting user profiling in general. The collection of personally identifiable information (PII) of users by search engines is referred to as tracking.
