Here is a streamlined client guide to ensure your mobile ad campaigns are visually compelling and high-performing. This document outlines essential creative requirements, including format specifications, dimensions, and best practices, to help you deliver engaging, mobile-optimized content that resonates with your audience and drives results.

Getting Started

  • FeedMob will provide static creative services, however some media partners may require non-standard ad sizes and we will ensure dimension accuracy in the onboarding process.
  • Please provide the following to your AM team in order to start creative work:
    • Vectorized logo (.ai format)
    • Your company brand guidelines
    • Brand specific font files
    • For any images required, please provide stock photography with appropriate licensing

Copy Guidelines

  • When creating CTA button copy for your ad, please provide several variations of copy for testing. A good rule of thumb for CTAs is 15 characters or less.
  • For main banners, main titles should have a character count of 25 or less, and subtitles should have a character count of 30 or less. Some media partners will allow more than this but we advise these limits to ensure that your message is clear, concise, and readable on small screens.
  • A general best practice for push notifications include main titles under 20 characters, subtitles under 25 characters. The shorter the better to ensure clarity and design optimization.
