For simple opt-in campaigns, there are now two creative types that you can split test against each other; the Text-Based and Image-Based creative types. These two creatives work well on individual campaigns and are highly recommended to split test the text-based version against the image-based version to see which type works best for your campaign.
What it is: An image-based layout that looks like a display ad. This layout allows you to have all of the same marketing text as the text-based version, in addition to display ad benefits such as customization and GIF animation.
Why should you use it: Increasing the CTR opt-in percentage on your existing campaign increases your eCPM organically, so you don’t need to raise your bids to increase your eCPM.
Key Benefits: Image-Based SOI gives you the ability to split test by creative type.
How to implement: Upload image-based creative into the platform.
