Creative Specs

The OpenRTB spec now supports the same basic meta elements for all native ad transactions.

The specs below will generally apply to all buying platforms accessing Sharethrough, but it is recommended buyers reference the DSP-specific guides in this wiki for additional requirements. 

The standard elements for all in-feed native ads are as follows:

Headline
The most important part of the native unit. OpenRTB provides for 3 lengths (25 characters, 90 characters, 140 characters - including spaces). Sharethrough supports all three, but recommends using headlines no greater than 90 characters to avoid cutoff. 

Description
Additional copy below the headline — maximum 140 characters, including spaces. Note that the description does not show up on all placements.

Content URL
The URL where the ad will drive traffic (display ads only).

Thumbnail
Sharethrough recommends providing one thumbnail for both mobile and desktop, while our recommended ratio is 1000x750 we can accept any size as long as they meet the minimum requirements. 

Minimum size by device: 
- Mobile: minimum 320x180 
- Desktop: minimum 600x315

Brand Name
The name of the brand associated with the ad.

Brand Logo (optional, but recommended)
The icon that shows up next to the brand name. 48x48 min

Video
No larger than 1GB
