display advertising

Display advertising[edit]

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 and semantic advertising to deliver display ads related to the content of the web page where the ads appear.[19]:118 Retargeting, 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[edit]

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 appletsHTML5Adobe Flash, and other programs.
Frame ad (traditional banner)[edit]
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.[citation needed]
Pop-ups/pop-unders[edit]
pop-up ad is displayed in a new web browser window that opens above a website visitor's initial browser window.[29] A pop-under ad opens a new browser window under a website visitor's initial browser window.[1]:22
Floating ad[edit]
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[edit]
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.[30] Expanding ads allow advertisers to fit more information into a restricted ad space.
Trick banners[edit]
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.[31] Trick banners typically do not mention the advertiser in the initial ad, and thus they are a form of bait-and-switch.[32][33] Trick banners commonly attract a higher-than-averageclick-through rate, but tricked users may resent the advertiser for deceiving them.[34]
Interstitial ads[edit]
An interstitial ad displays before a user can access requested content, sometimes while the user is waiting for the content to load.[35] Interstitial ads are a form of interruption marketing.[36][37]

Text ads[edit]

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.[38]

Search Engine Marketing (SEM)[edit]

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)[edit]

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.[39][40][41] Many vendors offer SEO services.[1]:22

[edit]

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[42] In addition to setting a maximum price per keyword, bids may include time, language, geographical, and other constraints.[19]:118 Search 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[edit]

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.[43]
