Create your ad texts in compliance with the maximum number of characters (including spaces):
- Headline: max. 35 characters
- Text: max. 80 characters
- Displayed URL: max. 35 characters
We use four image formats to present your ad optimally on all devices.
Since our publishers usually offer all four formats on their websites, it is necessary to add an image file for each of the formats for optimal performance. The images must not exceed a maximum file size of 2MB and must be uploaded in either JPEG or PNG format. For optimal display, even on high-resolution displays, we recommend using images with an edge length of at least 1000px.
Video ads must not exceed a maximum file size of 5MB and must not last longer than 15 seconds. After these 15 seconds, your video will be looped (it repeats automatically). We recommend a file resolution of 720p or Full HD. However, the bigger the better. Acceptable formats are: mp4, webm, mov and gif. No relevant information should be placed on the edges of the image, as your video will automatically be cropped to the required 1:1, 4:3, 16:9 and 10:3 aspect ratios. We also recommend creating all video ads in a separate ad group.
