Skycastle Creative considerations

Must be created internally by our Skycastle creative team.

Who is the target audience?
What is the overall goal of the campaign (e.g., click-throughs, branding, registration, KPIs)?
Compile any URLs, splash pages, brand/style guides, colors, logos, and pre-existing work.
What do we need to communicate?
Custom ad units will render on all modern browsers excluding Internet Explorer. Modern browsers include Chrome, Edge, FireFox, and Safari.
