Responsive ads automatically adjust their size, appearance and shape to fit the relevant available spaces. Some websites only allow ads in this format to be displayed. Therefore, using this type of ads means increasing the possibility of impressions in spaces where static ads are not supported. In order to create an ad of this kind, it only takes two images and two logos, one in landscape and the other square.
Landscape Logo (4: 1): 1200 × 300 (minimum required: 512 × 128)
Square Logo (1: 1): 1200 × 1200 (minimum required: 128 × 128)
Landscape Image (1.91: 1): 1200 × 628 (minimum required: 600 × 314)
Square Image (1: 1): 1200 × 1200 (minimum required: 300 × 300)
Size limit for the above images: 5 MB
Responsive ads have text fields (title, description ...), so if text is used in the image, it's best not to overdo it.
NOTE: to fit in some ad spaces, your image can be cropped horizontally (up to 5% on each side).
As mentioned, this type of display ad has a text part. It is divided into:
Short Title: Up to 30 characters
Long Title: Up to 90 characters
Description (up to 5 different): Up to 90 characters each
