How to design a Display Ad

Display ads should include the following content:

  1. Your logo and company name
  2. Message
  3. Promotion
  4. Call to Action (linked to your website or landing page)

In order to comply with exchange standards and pass the creative audit, your Display ads need to include brand identification which is also immediately visible on your linked landing page or website. This can be your logo, an icon, or company name.
