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:
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.
Additional copy below the headline — maximum 140 characters, including spaces. Note that the description does not show up on all placements.
The URL where the ad will drive traffic (display ads only).
Sharethrough recommends providing a thumbnail for both mobile and desktop:
- Mobile: minimum 320x180
- Desktop: minimum 1000x750
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
No larger than 1GB
