Image creative is a typical square-shaped image ad — from a small-sized banner to a full-screen interstitial. To maximize user reach and advertising performance, preparing image banners of all recommended sizes for your target country is essential. Optional sizes can improve your campaign performance, but it has a smaller impact than the recommended sizes.

Image ad best practices

• Some exchanges don't review image creatives without a brand logo.

  

  Tip: Avoid placing your brand logo in the upper right corner as it may interfere with the ad information button.

• A CTA button increases ad performance by inducing audiences to click the advertisement. 

  

  Tip:

  • Use a contrasting color for the CTA button with the background.
  • Use appropriate phrases for each campaign's characteristics and purpose.
  • Maintain a minimum of 10pt font size with letter-spacing for better legibility.
    
  • Avoid using excessively bold or thin fonts.
    
  • Abbreviate ad copy if there is limited space for the CTA button.
    
  • Keep logo > text > image > CTA format for clear delivery.
    
  • Use plain text, without any extravagant effects.
  • Use high-resolution images for the creatives.
  • Use uncropped images.
    

• Promotions such as discounts, special prices, and limited sales can prompt users to respond quickly to advertisements. By highlighting such promotional information, you can improve advertising performance.
