Thumbnails are reduced-size versions of pictures or videos , used to help in recognizing and organizing them, serving the same role for images as a normal text index does for words. In the age of digital images , visual search engines and image-organizing programs normally use thumbnails, as do most modern operating systems or desktop environments, such as Microsoft Windows , macOS , KDE ( Linux ) and GNOME ( Linux ). On web pages, they also avoid the need to download larger files unnecessarily.
70-514: Clickbait (also known as link bait or linkbait ) is a text or a thumbnail link that is designed to attract attention and to entice users to follow ("click") that link and read, view, or listen to the linked piece of online content , being typically deceptive , sensationalized , or otherwise misleading . A " teaser " aims to exploit the "curiosity gap", providing just enough information to make readers of news websites curious , but not enough to satisfy their curiosity without clicking through to
140-413: A content creator 's overall engagement . There are various clickbait strategies, including the composition of headlines of news and online articles that build suspense and sensation, luring and teasing users to click. Some of the popular approaches in achieving these include the presentation of link and images that are interesting to the user, exploiting curiosity related to greed or prurient interest. It
210-429: 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. The process

GoTo.com (renamed Overture in 2001, and acquired by Yahoo! in 2003) created the first search advertising keyword auction in 1998. Google launched its " AdWords " (now renamed Google Ads) search advertising program in 2000 and introduced quality-based ranking allocation in 2002, which sorts search advertisements by
350-432: A USENET posting titled "Green Card Lottery – Final One?" 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. More recently, spam has evolved into a more industrial operation, where spammers use armies of virus-infected computers ( botnets ) to send spam remotely. Online banner advertising began in
420-676: A combination of bid price and searchers' likeliness to click on the ads. 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. Advertisers are also embracing social media and mobile advertising; mobile ad spending has grown 90% each year from 2010 to 2013. According to Ad Age Datacenter analysis, in 2017 over half of agency revenue came from digital work. The March 2021 eBay advertisement for
490-502: A combination of bid price, expected click-through rate, keyword relevancy and site quality. 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. Videos, interactive quizzes, and sponsored posts are all a part of this operation. Usually these ads are found on Facebook, Instagram, Twitter, and Snapchat . Mobile advertising
560-417: 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. This
630-534: 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. Despite the prevailing acceptable use policies, electronic mail marketing rapidly expanded 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
700-577: A moving target for advertisers. Many vendors offer SEO services. 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. In addition to setting a maximum price per keyword, bids may include time, language, geographical, and other constraints. Search engines originally sold listings in order of highest bids. Modern search engines rank sponsored listings based on
770-503: A penny was charged. This resulted in the advertisers monitoring the campaign by the number of clicks and were satisfied that the ads could be tracked. 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

980-461: A restricted ad space. Trick banners: A trick banner is a banner ad where the ad copy imitates some screen elements users commonly encounter, such as an operating system message or popular application message, to induce ad clicks. Trick banners typically do not mention the advertiser in the initial ad, and thus they are a form of bait-and-switch . Trick banners commonly attract a higher-than-average click-through rate , but tricked users may resent
1050-489: A small sketch . A "comprehensive" thumbnail sketch of a printed project, more or less to final size, is often referred to as a "comp", and can be highly detailed, with production information included. The purpose of thumbnails was to visualize the ideas in a miniature form, similar to an illustration shorthand. Often, the old school animators used this process to quickly jot down the key "poses" that were part of an animation sequence. These compact drawing were then pinned up above
1120-617: A user can access requested content, sometimes while the user is waiting for the content to load. Interstitial ads are a form of interruption marketing . 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 the 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. Search engine marketing , or SEM,
1190-410: A website visitor's initial browser window. A pop-under ad opens a new browser window under a website visitor's initial browser window. 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". Floating ad: A floating ad, or overlay ad, is a type of rich media advertisement that appears superimposed over
1260-489: A website, a fan page, an app, or a product. Some examples are: Facebook's "Sponsored Stories", LinkedIn's "Sponsored Updates", and Twitter's "Promoted Tweets". 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. The process by which online advertising
1330-558: Is "a sensationalized headline or piece of text on the Internet designed to entice people to follow a link to an article on another web page." In 2014, BuzzFeed editor Ben Smith stated that his publication avoided using clickbait, using a strict definition of clickbait as a headline that is dishonest about the content of the article. Smith noted that Buzzfeed headlines such as "A 5-Year-Old Girl Raised Enough Money To Take Her Father Who Has Terminal Cancer To Disney World" delivered exactly what
1400-403: Is a form of fraud . ( Click fraud , however, is a separate form of online misrepresentation which uses a more extreme disconnect between what is being presented in the frontside of the link versus what is on the click-through side of the link, also encompassing malicious code .) The term clickbait does not encompass all cases where the user arrives at a destination that is not anticipated from
1470-456: Is ad copy comprising an entire email or a portion of an email message. 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).

Industry groups such as

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
1680-452: 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. 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. The primary reason behind
1750-519: Is displayed can involve many parties. In the simplest case, the website publisher selects and serves the ads. Publishers which operate their own advertising departments may use this method. Alternatively ads may be outsourced to an advertising agency under contract with the publisher, and served from the advertising agency's servers or ad space may be offered for sale in a bidding market using an ad exchange and real-time bidding, known as programmatic advertising. Programmatic advertising involves automating
1820-655: Is done using 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 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. Craigslist and eBay are two prominent providers of online classified listings. Adware
1890-409: Is generally regarded as clickbait. A more commonly used definition is a headline that intentionally over-promises and under-delivers. The articles associated with such headlines often are unoriginal, and either merely restate the headline, or copies content from a more genuine news source. The term clickbait is sometimes used for any article that is unflattering to a person. In such cases, the article
1960-423: Is not actually clickbait by any legitimate definition of the term. From a historical perspective, the techniques employed by clickbait authors can be considered derivative of yellow journalism , which presented little or no legitimate well-researched news and instead used eye-catching headlines that included exaggerations of news events, scandal-mongering, or sensationalism . One cause of such sensational stories

2100-510: 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. Interstitial ads : An interstitial ad displays before
2170-569: 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. Adware installed without the user's permission is a type of malware .

Broadly speaking, there are three types of data obtained through such a data management platform: 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
2310-494: Is the controversial practice called checkbook journalism , where news reporters pay sources for their information without verifying its truth. In the U.S. it is generally considered an unethical practice, as it often turns celebrities and politicians into lucrative targets of unproven allegations. According to Washington Post writer Howard Kurtz , "this thriving tabloid culture has erased the old definitions of news by including tawdry and sensational stories about celebrities for

2450-503: The 1980s. The term vignette is sometimes used to describe an image that is smaller than the original, larger than a thumbnail, but no more than 250 pixels in the long dimension. Directors , storyboard artists and graphic designers , as well as other kinds of visual artists, use the term "thumbnail sketch" to describe a small drawing on paper (usually part of a group) used to explore multiple ideas quickly. Thumbnail sketches are similar to doodles , but may include as much detail as
2520-700: The Mobile Marketing Association have attempted to standardize mobile ad unit specifications, similar to the IAB's efforts for general online advertising. 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. The Interactive Advertising Bureau predicts continued growth in mobile advertising with
2590-466: The adoption of location-based targeting and other technological features not available or relevant on personal computers. In 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
2660-443: The advertiser can later retarget the user with ads from the site the user visited. As advertisers collect data across multiple external websites about a user's online activity, they can create a detailed profile of the user's interests to deliver even more targeted advertising. This aggregation of data is called behavioral targeting . Advertisers can also target their audience by using contextual to deliver display ads related to
2730-448: The advertiser for deceiving them. "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" ) 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

In 2017, Internet advertising revenues in the United States totaled $ 83.0 billion, a 14% increase over the $ 72.50 billion in revenues in 2016. And research estimates for 2019's online advertising spend put it at $ 125.2 billion in the United States, some $ 54.8 billion higher than

Like other advertising media, online advertising frequently involves
3010-427: The clickbait problem while social media platforms such as Twitter and Facebook have implemented algorithms to filter clickbait contents. Social media groups, such as Stop Clickbait, combat clickbait by giving a short summary of the clickbait article, closing the "curiosity gap". Clickbait-reporting browser plug-ins have also been developed by the research community in order to report clickbait links for further advances in
3080-538: The content of the web page where the ads appear. Retargeting, behavioral targeting, and contextual advertising all are designed to increase an advertiser's return on investment , or ROI, over untargeted ads. Advertisers may also deliver ads based on a user's suspected geography through geotargeting .

These desired actions can be an email submission, a phone call, filling out an online form, or an online order being completed. 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
3220-538: 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. The first clickable web ad was sold by Global Network Navigator in 1993 to a Silicon Valley law firm. In 1994, web banner advertising became mainstream when HotWired , the online component of Wired Magazine , and Time Warner 's Pathfinder sold banner ads to AT&T and other companies. The first AT&T ad on HotWired had
3290-450: The 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". The NSFNet began phasing out its commercial use ban in 1991. The first widely publicized example of online advertising was conducted via electronic mail . On 3 May 1978,
3360-440: The expression first appears in the mid-19th century to refer to 'a drawing the size of the thumbnail'. The word was then used figuratively, in both noun and adjective form, to refer to anything small or concise, such as a biographical essay. The use of the word "thumbnail" in the specific context of computer images as 'a small graphical representation, as of a larger graphic, a page layout, etc.' appears to have been first used in
3430-468: The face slightly reduced than an indistinct figure. However, this may mislead the viewer about what the image contains, so is more suited to artistic presentations than searching or catalogue browsing. Thumbnail makes for smaller, more easily viewable pages and also allows viewers to have control over exactly what they want to see. In 2002, the court in the US case Kelly v. Arriba Soft Corporation ruled that it

Thumbnail Thumbnails are ideally implemented on web pages as separate, smaller copies of the original image, in part because one purpose of a thumbnail image on a web page is to reduce bandwidth and download time. Some web designers produce thumbnails with HTML or client-side scripting that makes
3570-588: The first Asian Giant Hornet ( Vespa mandarinia ) nest in the US was controversial. The owner of the first nest discovered in the United States – in Blaine, Washington – demanded its return instead of allowing scientific investigation, and proceeded to sell it. A nearby beekeeper bought it to gift it back to the state entomology team which had exterminated it, for study. Display advertising conveys its advertising message visually using text, logos, animations, videos, photographs, or other graphics. Display advertising

#17329015220503640-408: The first form of web banners. 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 propose standardized pixel dimensions for ad units. Pop-ups/pop-unders: A pop-up ad is displayed in a new web browser window that opens above
3710-450: The headline promised. The fact that the headline was written to be eye-catching was irrelevant in Smith's view, since the headline accurately described the article. Facebook, while trying to reduce the amount of clickbait shown to users, defined the term as a headline that encourages users to click, but does not tell them what they will see. However, this definition excludes a lot of content that
3780-452: The link that is clicked. A defining characteristic of clickbait is misrepresentation in the enticement presented to the user to manipulate them to click onto a link. While there is no universally agreed-upon definition of clickbait, Merriam-Webster defines clickbait as "something designed to make readers want to click on a hyperlink, especially when the link leads to content of dubious value or interest." Dictionary.com states that clickbait
3850-511: The linked content. Clickbait headlines often add an element of dishonesty, using enticements that do not accurately reflect the content being delivered. The "-bait" suffix makes an analogy with fishing, where a hook is disguised by an enticement ( bait ), presenting the impression to the fish that it is a desirable thing to swallow. Before the Internet , a marketing practice known as bait-and-switch used similar dishonest methods to hook customers. In extreme degree, like bait-and-switch, clickbait
3920-494: 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 ,
3990-627: The political spectrum – including Breitbart News , Huffington Post , Salon , Townhall and the Gawker Media blogs – which profited by producing shareable short-form pieces offering simple moral judgements on political and cultural issues. Click-through rates (CTRs) on YouTube show that videos with hyperbolic or misleading title, created for the purpose of being attention-grabbing, displayed higher click-through rates than videos which did not. Clickbait tactics generally lead to higher clickthrough rates, and to higher revenue and optimization of
4060-425: The range of possible locations. For example, with mobile devices, advertisers can sometimes use a phone's GPS receiver or the location of nearby mobile towers. Cookies and other persistent data on a user's machine may help narrow down a user's location even further. This involves many parties interacting automatically in real time. In response to a request from the user's browser, the publisher content server sends
4130-409: The recommendations page. Recommendations on YouTube are driven by a viewer's personal watch history and videos that get an abundance of clicks. With a streaming platform like YouTube, which has upwards of 30 million active users a day, the videos that are watched are very likely to be those with clickbait in either the title or thumbnail of the video, garnering attention and therefore clicks. By 2014,
4200-423: The requested website's content. Floating ads may disappear or become less obtrusive after a pre-set 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. Expanding ads allows advertisers to fit more information into
4270-400: The rise of post-truth politics . Katherine Viner , editor-in-chief at The Guardian wrote that "chasing down cheap clicks at the expense of accuracy and veracity" undermined the value of journalism and truth. Emotional subjects with stark headlines are widely shared and clicked, which resulted in what Slate described as an "aggregation of outrage" and a proliferation of websites across

However, this concept was popularized by Google. Google Ad words was convenient for advertisers to use and create campaigns. And, they realized that the tool did a fair job, by charging only for someone's click on the ad, which reported as the cost-per-click for which

It can also be used for phishing attacks for the purpose of spreading malicious files or stealing user information. The attack occurs once the user opens the link provided to learn more. Clickbait has also been used for political ends and has been blamed for
4480-402: The sale and delivery of digital advertising on websites and platforms via software rather than direct human decision-making. Advertisements are selected and targeted to audiences via ad servers which 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

Many internet users also find online advertising disruptive and have increasingly turned to ad blocking for a variety of reasons. Online ad revenues also may not adequately replace other publishers' revenue streams. Declining ad revenue has led some publishers to place their content behind paywalls . In
4620-452: The ubiquity of clickbait on the web had begun to lead to a backlash against its use. Satirical newspaper The Onion launched a new website, ClickHole , that parodied clickbait websites such as Upworthy and BuzzFeed , and in August 2014, Facebook announced that it was taking technical measures to reduce the impact of clickbait on its social network, using, among other cues, the time spent by
4690-399: The user on visiting the linked page as a way of distinguishing clickbait from other types of content. Ad blockers and a general fall in advertising clicks also affected the clickbait model, as websites moved toward sponsored advertising and native advertising where the content of the article was more important than the click-rate. Web browsers have incorporated tools to detect and mitigate
4760-431: The user's browser shrink the picture, rather than use a smaller copy of the image. This results in no saved bandwidth, and the visual quality of browser resizing is usually less than ideal. Displaying a significant part of the picture instead of the full frame can allow the use of a smaller thumbnail while maintaining recognizability. For example, when thumbnailing a full-body portrait of a person, it may be better to show
4830-418: 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
4900-503: Was fair use for Internet search engines to use thumbnail images to help web users find what they seek. The word "thumbnail" is a reference to the human thumbnail and alludes to the small size of an image or picture, comparable to the size of the human thumbnail. While the earliest use of the word in this sense dates back to the 17th century, the American Heritage Dictionary of Idioms is reported to have documented that
