To run a native display campaigns on DBM, users must build their native creative.
Once logged in, here’s how to create a native ad banner:
1) Select "Format Gallery" from the Creative sidebar
2) Select "Native" tab, and choose “Native Display”
3) Enter creative information
Brand logo: 1:1 ratio (min 100x100)
Image: Use rectangular image here, 1200×627 pixels
Here is a tool to help you resize your images to the DBM specs : http://generator.sharethrough.com/thumbnails/new
Square Image: Though it says optional, DO NOT PUT AN IMAGE HERE
Long headline: 50 character max
Short headline: 25 character max - required field, though it won't display on Sharethrough inventory
Long body text: 140 character description
Short body text: 90 character description - required field, though it won't display on Sharethrough inventory
Note that each placement on Sharethrough's inventory is made to host up to 90 characters, so we will always serve the long headline (50 characters in DBM) when provided.
That's why we recommend always implementing a long headline/body, and use a placeholder in the short headline/body.
