• Code should include the mandatory macro {CONVERSION_ID}. This is used to track your App/website events and ensures that GSM360 is able to track unique bid ID.
• Code should include the click macro {HTML_CLICK_URL}. This is to ensure GSM360 is able to track clicks and display those clicks in the dashboard.
• Code should not contain <iframe> due to rendering and reporting issues.
• Code should not include single-line comments: // or <!--
• Code should be minified, which is the process of removing unnecessary characters and white spaces from a source code file without affecting its functionality.
• All references to external assets must be absolute URLs instead of relative URLs and HTTPS instead of HTTP.
  

• Loading Screen: Playable Ads must have a loading screen, which is ideally clickable (especially in cases where an ad takes a significant amount of time to load) and populated with the target URL directly. You can use the loading screen of the game/app to increase the recognition factor and branding effect.
  
  
• Tutorial: Create a tutorial for the first 2-3 steps to instruct users how to engage with the game. For instance, add a text-box informing the user what they need to do in order to start playing. A good idea is to add animated pointers or arrows.
  
  
• CTA Screen: It is recommended to make the whole screen clickable, and to add an engaging end-screen CTA to improve engagement rates.

Video

• Video Assets
  • Come in various sizes and duration, catering to a wide range of ad formats.
  • Increase brand awareness for new or little-known brands.
  • Drive click-through performance with engaging video and end cards.
  • Guarantee a completed video view through Rewarded, unskippable placements (for first 15 seconds of video)
  • Increase reach at an efficient cost through Interstitial placements.

• Interstitial vs Rewarded:
  • Interstitial placements are skippable, usually after 5 seconds. This varies across exchanges, e.g. Chartboost provides a 3-second skip delay while AppLovin provides an 8-second skip delay. Interstitials are typically cheaper compared to Rewarded placements.
  • Rewarded placements are non-skippable during the first 30 seconds. Make the most of this time and the user's willingness to view the creative!
    
    
• End Card: End Cards provide an additional way for the user to interact with your creative, hence increasing engagement. They may close immediately or after 5-6 seconds.
  
  
• Orientation:

  Portrait is preferred; most mobile users use their phones in a vertical / portrait position. As such, the majority of bid requests generated correspond to portrait-oriented impression opportunities. However, to maximize reach (in terms of eligible bid requests), it is recommended to run both portrait and landscape versions.
  

  
  

  
  
  

• Resolution:
  
  • Portrait creatives will be eligible for ALL portrait oriented bid requests.
  • Landscape creatives will be eligible for ALL landscape oriented bid requests.
  • Squared creatives will be eligible for ALL portrait and landscape oriented bid requests, though resulting in poorer experience due to the introduction of black borders.
  
  
• Duration: Avoid videos shorter than 5s, as this is usually the minimum duration for many ad exchanges. Doing so will guarantee maximum reach for your creative. Videos below 30s have the highest potential reach across all ad exchanges.
