Half page

Although the name is Half Page, the size of this banner ad does not cover half the website. In addition, with generous dimensions of 300 pixels wide by 600 pixels high (300×600), the ad is larger and more striking than any other Ad and offers plenty of room for creativity. It is therefore ideally suited as an advertising form for large-scale, attention-grabbing campaigns. The Ad can be seen beside the content along the right side of website pages, mostly starting in the upper portion of the page.

  • The .zip file must contain at least one index.htm or index.html file, or another unique .htm or .html file. This file will be used as the starting point for the HTML5 advertisement.The main .html file contains a clickTAG. Our ad server counts on it to correctly track the clicks.

  • The main .html file refers relatively to all code and assets. This means that all links in HTML5-creative, like the link to an image in the ad, have to use a relative path, for example /graphics/ad-image.png or <img src=”/graphics/ad-image.png”>. In this way, the ad can be independent and therefore run or be displayed independently without a network connection. External libraries and web fonts may constitute an exception to thisto this guideline.
  • There are no specific rules for the folder structure in the .zip file. All files can be organized in different subfolders or in the root folder.
  • The number of files should be kept to a minimum (maximum 15)because each other file leads to a separate request, which affects the performance of the web page on which the ad is loaded.
  • If you are linking to external libraries (jquery, etc.), ensure the request is made via HTTPS (SSL). x Send all HTML5 .zip files through a service like WeTransfer or Dropbox
