# Online advertising formats ## Online display advertising Online display advertising messages can be communicated by text, visuals (such as graphics and video) and/or audio, offering a wide range of opportunities. The messages are displayed alongside the content on a publisher’s platform but may also float on top of the content. Online display advertising campaigns can be categorised into three primary forms: web banner ads, rich media ads, and text ads. ### Web banners Web banners are graphical advertisements that can be of any dimension. They are typically static and uploaded as a JPEG, GIF, or PNG file. A GIF file is the only format allowing simple animation effects, while HTML5 files are used for more advanced animation effects. The following is a list of the most frequently used ad format dimensions and their names:Medium rectangle (300*250): | Wide skyscraper (160*600): |

#### Interstitial | ||
[](https://documentation.adhese.org/uploads/images/gallery/2024-06/SnbFRTOGrtOwyEYL-online-advertising-formats5.png) | An *interstitial* ad is served between pages as a user navigates from one web page to the next. The ad is displayed in a separate browser window before the requested page is displayed. The ad will disappear after a short period or when the user clicks through it or clicks it away. An *interstitial* ad is also known as a *splash*, *transitional*, or *between-the-page* ad. | |
#### **Floating ad or overlay** | ||
[](https://documentation.adhese.org/uploads/images/gallery/2024-06/nrVPzzWTede5K7qA-online-advertising-formats6.png) | Like an interstitial ad, a *floating ad* or *overlay* may serve as a way for a user to navigate to another web page. However, the advertisement appears above the usual content of the webpage. A floating ad can also be delivered after a user has been on the webpage for a specific period. This is a common practice for promoting a website’s newsletter. A floating advertisement disappears after a short period or when a user clicks through the advertisement or clicks it away. | |
#### Expandable | ||
[](https://documentation.adhese.org/uploads/images/gallery/2024-06/1syhOB5fXOH2YeYs-online-advertising-formats7.png) | [](https://documentation.adhese.org/uploads/images/gallery/2024-06/QjGvgdA3SM9pffwC-online-advertising-formats8.png) | An *expandable* ad will expand beyond its actual dimensions once a user clicks or hovers over it. The ad expands over the page content while the original content remains in place. |
#### Push-down | ||
[](https://documentation.adhese.org/uploads/images/gallery/2024-06/RQX2euKqqicSBXeO-online-advertising-formats9.png) | [](https://documentation.adhese.org/uploads/images/gallery/2024-06/AfmzOCWfODJ0ejbd-online-advertising-formats10.png) | A *push-down* ad is placed at the top of a web page. Upon clicking or hovering over the ad, the creative expands downwards, with the original content shifting down with it. |
#### **Homepage takeover** | ||
---|---|---|
[](https://documentation.adhese.org/uploads/images/gallery/2024-06/mqRlC0Ljxee2GFBK-online-advertising-formats11.png) | A *homepage* takeover ad guarantees maximum visibility of the advertiser’s message, as this ad utilises all (or a subset of) existing advertising positions on a homepage. | |
#### **Wallpaper skin** | ||
[](https://documentation.adhese.org/uploads/images/gallery/2024-06/aPIxhdOlD5BwPgsA-online-advertising-formats12.png) | The *wallpaper skin* ad is displayed on a web page's left and right-hand rails. The position of the wallpaper image remains fixed when a user scrolls down the page. This format is often delivered with a leaderboard or other format (see Homepage takeover). | |
#### **Floor ad** | ||
[](https://documentation.adhese.org/uploads/images/gallery/2024-06/jIIlh8SnIiC0XJJM-online-advertising-formats13.png) | A *floor* ad is positioned at the bottom of a browser window and can be expanded in response to user interaction. | |
#### **In-banner video** | ||
[](https://documentation.adhese.org/uploads/images/gallery/2024-06/nVfimT0EObJBaJbs-online-advertising-formats14.png) | An *in-banner video* ad does not deliver a video within a video player but inside the dimensions of any display ad creative for a given position. It is possible to initiate video playback automatically, but it is recommended that the audio be started only upon user interaction. | |
#### In-read | ||
[](https://documentation.adhese.org/uploads/images/gallery/2024-06/IeSpSaT5pyDyU4uU-online-advertising-formats15.png) | [](https://documentation.adhese.org/uploads/images/gallery/2024-06/pDXHmD1QPrSt83gx-online-advertising-formats16.png) | An *in-read* ad contains a video integrated into the middle of an article. The video's playback automatically starts once the creative is in view for 50%. Should the user scroll past the video, playback will be paused and resume when the video is again in view. The video disappears after completion. |
