    Online advertising, also called online marketing or Internet advertising or web advertising, is a form of marketing and advertising which uses the Internet to deliver promotional marketing messages to consumers. Consumers view online advertising as an unwanted distraction with few benefits and have increasingly turned to ad blocking for a variety of reasons.

    It includes email marketing, search engine marketing (SEM), social media marketing, many types of display advertising (including web banner advertising), and mobile advertising. Like other advertising media, online advertising frequently involves both a publisher, who integrates advertisements into its online content, and an advertiser, who provides the advertisements to be displayed on the publisher's content. Other potential participants include advertising agencies who help generate and place the ad copy, an ad server which technologically delivers the ad and tracks statistics, and advertising affiliates who do independent promotional work for the advertiser.

    In 2011, Internet advertising revenues in the United States surpassed those of cable television and nearly exceeded those of broadcast television.[1]:19 In 2013, Internet advertising revenues in the United States totaled $42.8 billion, a 17% increase over the $36.57 billion in revenues in 2012.[2]:4-5 U.S. internet ad revenue hit a historic high of $20.1 billion for the first half of 2013, up 18% over the same period in 2012.[3] Online advertising is widely used across virtually all industry sectors.[1]:16

    Many common online advertising practices are controversial and increasingly subject to regulation. Online ad revenues may not adequately replace other publishers' revenue streams. Declining ad revenue has led some publishers to hide their content behind paywalls.[4]


    History

    In early days of the Internet, online advertising was mostly prohibited. For example, two of the predecessor networks to the Internet, ARPANET and NSFNet, had "acceptable use policies" that banned network "use for commercial activities by for-profit institutions".[5] [6] The NSFNet began phasing out its commercial use ban in 1991.[7][8] [9] [10]

    Email

    The first widely publicized example of online advertising was conducted via electronic mail. On 3 May 1978, a marketer from DEC (Digital Equipment Corporation), Gary Thuerk, sent an email to most of the ARPANET's American west coast users, advertising an open house for a new model of a DEC computer.[6][11] Despite the prevailing acceptable use policies, electronic mail marketing rapidly expanded[12] and eventually became known as "spam."

    The first known large-scale non-commercial spam message was sent on 18 January 1994 by an Andrews University system administrator, by cross-posting a religious message to all USENET newsgroups.[13] Four months later, Laurence Canter and Martha Siegel, partners in a law firm, broadly promoted their legal services in a USENET posting titled "Green Card Lottery - Final One?"[14] Canter and Siegel's Green Card USENET spam raised the profile of online advertising, stimulating widespread interest in advertising via both Usenet and traditional email.[13] More recently, spam has evolved into a more industrial operation, where spammers use armies of virus-infected computers (botnets) to send spam remotely.[11]

    Display ads

    Online banner advertising began in the early 1990s as page owners sought additional revenue streams to support their content. Commercial online service Prodigy displayed banners at the bottom of the screen to promote Sears products.[15] The first clickable web ad was sold by Global Network Navigator in 1993 to a Silicon Valley law firm.[16] In 1994, web banner advertising became mainstream when HotWired, the online component of Wired Magazine, sold banner ads to AT&T and other companies. The first AT&T ad on HotWired had a 44% click-through rate, and instead of directing clickers to AT&T's website, the ad linked to an online tour of seven of the world's most acclaimed art museums.[17][18]

    Search ads

    GoTo.com (renamed Overture in 2001, and acquired by Yahoo! in 2003) created the first search advertising keyword auction in 1998.[19]:119 Googlelaunched its "AdWords" search advertising program in 2000[20] and introduced quality-based ranking allocation in 2002, [21] which sorts search advertisements by a combination of bid price and searchers' likeliness to click on the ads.[19] :123

    Recent trends

    More recently, companies have sought to merge their advertising messages into editorial content or valuable services. Examples include Red Bull's Red Bull Media House streaming Felix Baumgartner's jump from space online, Coca-Cola's online magazines, and Nike's free applications for performance tracking.[18] Advertisers are also embracing social media[22] [23] and mobile advertising; mobile ad spending has grown 90% each year from 2010 to 2013.[1]:13

    Delivery methods

    Display advertising

    Display advertising conveys its advertising message visually using text, logos, animations, videos, photographs, or other graphics. Display advertisers frequently target users with particular traits to increase the ads' effect. Online advertisers (typically through their ad servers) often use cookies, which are unique identifiers of specific computers, to decide which ads to serve to a particular consumer. Cookies can track whether a user left a page without buying anything, so the advertiser can later retarget the user with ads from the site the user visited.[24]

    As advertisers collect data across multiple external websites about a user's online activity, they can create a detailed picture of the user's interests to deliver even more targeted advertising. This aggregation of data is called behavioral targeting.[25] Advertisers can also target their audience by using contextual to deliver display ads related to the content of the web page where the ads appear.[19] :118Retargeting, behavioral targeting, and contextual advertising all are designed to increase an advertiser's return on investment, or ROI, over untargeted ads.[26]

    Advertisers may also deliver ads based on a user's suspected geography through geotargeting. A user's IP address communicates some geographic information (at minimum, the user's country or general region). The geographic information from an IP can be supplemented and refined with other proxies or information to narrow the range of possible locations.[27] For example, with mobile devices, advertisers can sometimes use a phone's GPS receiver or the location of nearby mobile towers.[28] Cookies and other persistent data on a user's machine may provide help narrowing a user's location further.[27]

    Web banner advertising

    Web banners or banner ads typically are graphical ads displayed within a web page. Many banner ads are delivered by a central ad server.

    Banner ads can use rich media to incorporate video, audio, animations, buttons, forms, or other interactive elements using Java applets, HTML5, Adobe Flash, and other programs.

    Frame ad (traditional banner)

    Frame ads were the first form of web banners.[17] The colloquial usage of "banner ads" often refers to traditional frame ads. Website publishers incorporate frame ads by setting aside a particular space on the web page. The Interactive Advertising Bureau's Ad Unit Guidelines proposes standardized pixel dimensions for ad units.[29]

    Pop-ups/pop-unders

    A pop-up ad is displayed in a new web browser window that opens above a website visitor's initial browser window.[30] A pop-under ad opens a new browser window under a website visitor's initial browser window.[1]:22 Pop-under ads and similar technologies are now advised against by online authorities such as Google, who state that they "do not condone this practice".[31]

    Floating ad

    A floating ad, or overlay ad, is a type of rich media advertisement that appears superimposed over the requested website's content. Floating ads may disappear or become less obtrusive after a preset time period.

    Expanding ad

    An expanding ad is a rich media frame ad that changes dimensions upon a predefined condition, such as a preset amount of time a visitor spends on a webpage, the user's click on the ad, or the user's mouse movement over the ad.[32] Expanding ads allow advertisers to fit more information into a restricted ad space.

    Trick banners

    A trick banner is a banner ad where the ad copy imitates some screen element users commonly encounter, such as an operating system message or popular application message, to induce ad clicks.[33] Trick banners typically do not mention the advertiser in the initial ad, and thus they are a form of bait-and-switch.[34] [35] Trick banners commonly attract a higher-than-average click-through rate, but tricked users may resent the advertiser for deceiving them.[36]

    News Feed Ads

    "News Feed Ads", also called "Sponsored Stories", "Boosted Posts", typically exist on Social Media Platforms that offer a steady stream of information updates ("news feed"[37]) in regulated formats (i.e. in similar sized small boxes with a uniform style). Those advertisements are intertwined with non-promoted news that the users are reading through. Those advertisements can be of any content, such as promoting a website, a fan page, an app, or a product.

    Some examples are: Facebook's "Sponsored Stories",[38] LinkedIn's "Sponsored Updates",[39] and Twitter's "Promoted Tweets".[40]

    This display ads format falls into its own category because unlike banner ads which are quite distinguishable, News Feed Ads' format blends well into non-paid news updates. This format of online advertisement yields much higher click-through rates than traditional display ads[41][42]

    Display advertising process overview

    The process by which online advertising is displayed can involve many parties. In the simplest case, the web site publisher selects and serves the ads. Publishers which operate their own advertising departments may use this method.

    Online advertising serving process - simple publisher case

    The ads may be outsourced to an advertising agency under contract with the publisher, and served from the advertising agency's servers.

    Online advertising serving process using online bidding

    Alternatively, ad space may be offered for sale in a bidding market using an ad exchange and real-time bidding. This involves many parties interacting automatically in real time. In response to a request from the user's browser, the publisher content server sends the web page content to the user's browser over the Internet. The page does not yet contain ads, but contains links which cause the user's browser to connect to the publisher ad server to request that the spaces left for ads be filled in with ads. Information identifying the user, such as cookies and the page being viewed, is transmitted to the publisher ad server.

    The publisher ad server then communicates with a supply-side platform server. The publisher is offering ad space for sale, so they are considered the supplier. The supply side platform also receives the user's identifying information, which it sends to a data management platform. At the data management platform, the user's identifying information is used to look up demographic information, previous purchases, and other information of interest to advertisers.

    Broadly speaking, there are three types of data obtained through such a data management platform:

    First party data refers to the data retrieved from customer relationship management (CRM) platforms, in addition to website and paid media content or cross-platform data. This can include data from customer behaviors, actions or interests.[43]
    Second party data refers to an amalgamation of statistics related to cookie pools on external publications and platforms. The data is provided directly from the source (adservers, hosted solutions for social or an analytics platform). It is also possible to negotiate a deal with a particular publisher to secure specific data points or audiences. [44]
    Third party data is sourced from external providers and often aggregated from numerous websites. Businesses sell third-party data and are able to share this via an array of distribution avenues.[45]

    This customer information is combined and returned to the supply side platform, which can now package up the offer of ad space along with information about the user who will view it. The supply side platform sends that offer to an ad exchange.

    The ad exchange puts the offer out for bid to demand-side platforms. Demand side platforms act on behalf of ad agencies, who sell ads which advertise brands. Demand side platforms thus have ads ready to display, and are searching for users to view them. Bidders get the information about the user ready to view the ad, and decide, based on that information, how much to offer to buy the ad space. According to the Internet Advertising Bureau, a demand side platform has 10 milliseconds to respond to an offer. The ad exchange picks the winning bid and informs both parties.

    The ad exchange then passes the link to the ad back through the supply side platform and the publisher's ad server to the user's browser, which then requests the ad content from the agency's ad server. The ad agency can thus confirm that the ad was delivered to the browser. [46]

    This is simplified, according to the IAB. Exchanges may try to unload unsold ("remnant") space at low prices through other exchanges. Some agencies maintain semi-permanent pre-cached bids with ad exchanges, and those may be examined before going out to additional demand side platforms for bids. The process for mobile advertising is different and may involve mobile carriers and handset software manufacturers.[46]

    Interstitial

    An interstitial ad displays before a user can access requested content, sometimes while the user is waiting for the content to load.[47] Interstitial ads are a form of interruption marketing.[48] [49]

    Text ads

    A text ad displays text-based hyperlinks. Text-based ads may display separately from a web page's primary content, or they can be embedded by hyperlinking individual words or phrases to advertiser's websites. Text ads may also be delivered through email marketing or text message marketing. Text-based ads often render faster than graphical ads and can be harder for ad-blocking software to block.[50]

    Search engine marketing (SEM)

    Search engine marketing, or SEM, is designed to increase a website's visibility in search engine results pages (SERPs). Search engines provide sponsored results and organic (non-sponsored) results based on a web searcher's query.[19] :117 Search engines often employ visual cues to differentiate sponsored results from organic results. Search engine marketing includes all of an advertiser's actions to make a website's listing more prominent for topical keywords.

    Search engine optimization (SEO)

    Search engine optimization, or SEO, attempts to improve a website's organic search rankings in SERPs by increasing the website content's relevance to search terms. Search engines regularly update their algorithms to penalize poor quality sites that try to game their rankings, making optimization a moving target for advertisers. [51] [52][53] Many vendors offer SEO services.[1]:22

    Sponsored search (also called sponsored links, search ads, or paid search) allows advertisers to be included in the sponsored results of a search for selected keywords. Search ads are often sold via real-time auctions, where advertisers bid on keywords.[19]:118[54] In addition to setting a maximum price per keyword, bids may include time, language, geographical, and other constraints.[19] :118Search engines originally sold listings in order of highest bids.[19]:119 Modern search engines rank sponsored listings based on a combination of bid price, expected click-through rate, keyword relevancy and site quality. [21]

    Social media marketing

    Social media marketing is commercial promotion conducted through social media websites. Many companies promote their products by posting frequent updates and providing special offers through their social media profiles. [55]

    Mobile advertising

    Mobile advertising is ad copy delivered through wireless mobile devices such as smartphones, feature phones, or tablet computers. Mobile advertising may take the form of static or rich media display ads, SMS (Short Message Service) or MMS (Multimedia Messaging Service) ads, mobile search ads, advertising within mobile websites, or ads within mobile applications or games (such as interstitial ads, "advergaming," or application sponsorship).[1]:23 Industry groups such as the Mobile Marketing Association have attempted to standardize mobile ad unit specifications, similar to the IAB's efforts for general online advertising.[49]

    Mobile advertising is growing rapidly for several reasons. There are more mobile devices in the field, connectivity speeds have improved (which, among other things, allows for richer media ads to be served quickly), screen resolutions have advanced, mobile publishers are becoming more sophisticated about incorporating ads, and consumers are using mobile devices more extensively.[1] :14 The Interactive Advertising Bureau predicts continued growth in mobile advertising with the adoption of location-based targeting and other technological features not available or relevant on personal computers.[1] :14In July 2014 Facebook reported advertising revenue for the June 2014 quarter of $2.68 billion, an increase of 67 percent over the second quarter of 2013. Of that, mobile advertising revenue accounted for around 62 percent, an increase of 41 percent on the previous year.

    Email advertising

    Email advertising is ad copy comprising an entire email or a portion of an email message.[1]:22 Email marketing may be unsolicited, in which case the sender may give the recipient an option to opt out of future emails, or it may be sent with the recipient's prior consent (opt-in).

    Chat advertising

    As opposed to static messaging, chat advertising refers to real time messages dropped to users on certain sites. This is done by the usage of live chat software or tracking applications installed within certain websites with the operating personnel behind the site often dropping adverts on the traffic surfing around the sites. In reality this is a subset of the email advertising but different because of its time window.

    Online classified advertising

    Online classified advertising is advertising posted online in a categorical listing of specific products or services. Examples include online job boards, online real estate listings, automotive listings, online yellow pages, and online auction-based listings.[1]:22 Craigslistand eBay are two prominent providers of online classified listings.

    Adware

    Adware is software that, once installed, automatically displays advertisements on a user's computer. The ads may appear in the software itself, integrated into web pages visited by the user, or in pop-ups/pop-unders.[56] Adware installed without the user's permission is a type of malware.[57]

    Affiliate marketing

    Affiliate marketing (sometimes called lead generation) occurs when advertisers organize third parties to generate potential customers for them. Third-party affiliates receive payment based on sales generated through their promotion.[1]:22 Affiliate marketers generate traffic to offers from affiliate networks, and when the desired action is taken by the visitor, the affiliate earns a commission. These desired actions can be an email submission, a phone call, filling out an online form, or an online order being completed.

    Content Marketing

    Content marketing is any marketing that involves the creation and sharing of media and publishing content in order to acquire and retain customers. This information can be presented in a variety of formats, including blogs, news, video, white papers, e-books, infographics, case studies, how-to guides and more.

    Considering that most marketing involves some form of published media, it is almost (though not entirely) redundant to call 'content marketing' anything other than simply 'marketing'. There are, of course, other forms of marketing (in-person marketing, telephone-based marketing, word of mouth marketing, etc.) where the label is more useful for identifying the type of marketing. However, even these are usually merely presenting content that they are marketing as information in a way that is different from traditional print, radio, TV, film, email, or web media.

    Online marketing platform

    Online marketing platform (OMP) is an integrated web-based platform that combines the benefits of a business directory, local search engine, search engine optimisation (SEO) tool, customer relationship management (CRM) package and content management system (CMS). Ebayand Amazon are used as online marketing and logistics management platforms. On Facebook, Twitter, YouTube, Pinterest, LinkedIn, and other Social Media, retail online marketing is also used. Online business marketing platforms such as Marketo, Aprimo, MarketBright and Pardot have been bought by major IT companies (Eloqua-Oracle, Neolane-Adobe and Unica-IBM).

    Unlike television marketing in which Neilsen TV Ratings can be relied upon for viewing metrics, online advertisers do not have an independent party to verify viewing claims made by the big online platforms.[58]

    Compensation methods

    Main article: Compensation methods

    Advertisers and publishers use a wide range of payment calculation methods. In 2012, advertisers calculated 32% of online advertising transactions on a cost-per-impression basis, 66% on customer performance (e.g. cost per click or cost per acquisition), and 2% on hybrids of impression and performance methods.[1]:17

    CPM (cost per mille)

    Cost per mille, often abbreviated to CPM, means that advertisers pay for every thousand displays of their message to potential customers (mille is the Latin word for thousand). In the online context, ad displays are usually called "impressions." Definitions of an "impression" vary among publishers,[59] and some impressions may not be charged because they don't represent a new exposure to an actual customer.[60] Advertisers can use technologies such as web bugs to verify if an impression is actually delivered.[61] [62] :59

    Publishers use a variety of techniques to increase page views, such as dividing content across multiple pages, repurposing someone else's content, using sensational titles, or publishing tabloid or sexual content. [63]

    CPM advertising is susceptible to "impression fraud," and advertisers who want visitors to their sites may not find per-impression payments a good proxy for the results they desire.[64] :1-4

    CPC (cost per click)

    CPC (Cost Per Click) or PPC (Pay per click) means advertisers pay each time a user clicks on the ad. CPC advertising works well when advertisers want visitors to their sites, but it's a less accurate measurement for advertisers looking to build brand awareness.[65] CPC's market share has grown each year since its introduction, eclipsing CPM to dominate two-thirds of all online advertising compensation methods.[1] :18[64]:1

    Like impressions, not all recorded clicks are valuable to advertisers. GoldSpot Media reported that up to 50% of clicks on static mobile banner ads are accidental and resulted in redirected visitors leaving the new site immediately.[66]

    CPE (cost per engagement)

    Cost per engagement aims to track not just that an ad unit loaded on the page (i.e., an impression was served), but also that the viewer actually saw and/or interacted with the ad.[67][68]

    CPV (cost per view)

    Cost per view video advertising. Both Google and TubeMogul endorsed this standardized CPV metric to the IAB's (Interactive Advertising Bureau) Digital Video Committee, and it's garnering a notable amount of industry support.[69] CPV is the primary benchmark used in YouTube Advertising Campaigns, as part of Google's AdWords platform.

    CPI (cost per install)

    The CPI compensation method is specific to mobile applications and mobile advertising. In CPI ad campaigns brands are charged a fixed of bid rate only when the application was installed.

    Attribution of ad value

    Main article: Attribution (marketing)

    In marketing, "attribution" is the measurement of effectiveness of particular ads in a consumer's ultimate decision to purchase. Multiple ad impressions may lead to a consumer "click" or other action. A single action may lead to revenue being paid to multiple ad space sellers.[70]

    Other performance-based compensation

    CPA (Cost Per Action or Cost Per Acquisition) or PPP (Pay Per Performance) advertising means the advertiser pays for the number of users who perform a desired activity, such as completing a purchase or filling out a registration form. Performance-based compensation can also incorporate revenue sharing, where publishers earn a percentage of the advertiser's profits made as a result of the ad. Performance-based compensation shifts the risk of failed advertising onto publishers.[64]:4, 16

    Fixed cost

    Fixed cost compensation means advertisers pay a fixed cost for delivery of ads online, usually over a specified time period, irrespective of the ad's visibility or users' response to it. One examples is CPD (cost per day) where advertisers pay a fixed cost for publishing an ad for a day irrespective of impressions served or clicks.

    Benefits of online advertising

    Cost

    The low costs of electronic communication reduce the cost of displaying online advertisements compared to offline ads. Online advertising, and in particular social media, provides a low-cost means for advertisers to engage with large established communities. [55] Advertising online offers better returns than in other media.[64]:1

    Measurability

    Online advertisers can collect data on their ads' effectiveness, such as the size of the potential audience or actual audience response,[19] :119 how a visitor reached their advertisement, whether the advertisement resulted in a sale, and whether an ad actually loaded within a visitor's view. [61][62] :59This helps online advertisers improve their ad campaigns over time.

    Formatting

    Advertisers have a wide variety of ways of presenting their promotional messages, including the ability to convey images, video, audio, and links. Unlike many offline ads, online ads also can be interactive.[18] For example, some ads let users input queries[71] or let users follow the advertiser on social media.[72] Online ads can even incorporate games.[73]

    Targeting

    Publishers can offer advertisers the ability to reach customizable and narrow market segments for targeted advertising. Online advertising may use geo-targeting to display relevant advertisements to the user's geography. Advertisers can customize each individual ad to a particular user based on the user's previous preferences.[26] Advertisers can also track whether a visitor has already seen a particular ad in order to reduce unwanted repetitious exposures and provide adequate time gaps between exposures.[74]

    Coverage

    Online advertising can reach nearly every global market, and online advertising influences offline sales.[75][76][77]

    Speed

    Once ad design is complete, online ads can be deployed immediately. The delivery of online ads does not need to be linked to the publisher's publication schedule. Furthermore, online advertisers can modify or replace ad copy more rapidly than their offline counterparts.[78]

    Concerns

    Security Concerns

    According to a US Senate investigation, the current state of online advertising endangers the security and privacy of users.[79]

    Eye-tracking studies have shown that Internet users often ignore web page zones likely to contain display ads (sometimes called "banner blindness"), and this problem is worse online than in offline media.[80] On the other hand, studies suggest that even those ads "ignored" by the users may influence the user subconsciously.[81]

    Fraud on the advertiser

    There are numerous ways that advertisers can be overcharged for their advertising. For example, click fraud occurs when a publisher or third parties click (manually or through automated means) on a CPC ad with no legitimate buying intent.[82] For example, click fraud can occur when a competitor clicks on ads to deplete its rival's advertising budget, or when publishers attempt to manufacture revenue.[82]

    Click fraud is especially associated with pornography sites. In 2011, certain scamming porn websites launched dozens of hidden pages on each visitor's computer, forcing the visitor's computer to click on hundreds of paid links without the visitor's knowledge. [83]

    As with offline publications, online impression fraud can occur when publishers overstate the number of ad impressions they have delivered to their advertisers. To combat impression fraud, several publishing and advertising industry associations are developing ways to count online impressions credibly.[84][85]
