Lead with a single message
Use a short headline, one visual focus and a clear next action. Keep the brand and offer legible at a glance, and test the design at the actual display size rather than only on a desktop preview.
Use contrast and type sizes that remain readable from the viewing position. Avoid placing essential information at the extreme edges until safe areas are confirmed. If the message needs a paragraph of explanation, move the detail to a mobile landing page and keep the screen creative focused.
Confirm the destination requirements
OORO's creative upload endpoint accepts JPEG, PNG, WebP, MP4 and WebM files. This is only the accepted file-type list; it does not define a universal aspect ratio, resolution, maximum file size or video duration.
Ask the campaign team to confirm the destination screen's current specifications and review process before producing final artwork. The team may request adjustments for fit or legibility.
Review before submission
Check spelling, offer dates, contact details, contrast, captions and any required advertiser disclosures. Ensure the landing page works on mobile and that QR codes, if used, are large enough to scan in the intended context. Preview a still frame at phone size and ask someone unfamiliar with the brief what they understood after a quick look.
Read the campaign process and plan a campaign. For advertising content, consult the ASCI Code.
