Set of sitelinks (SitelinksSet)
The SitelinksSet object contains from 1 to 8 additional links. For more information, see Sitelinks in the Help for Yandex.Direct.
An ad can only have one set of sitelinks (or none). The same set of sitelinks can be assigned to multiple ads.
Use the Sitelinks service for creating and deleting sets of sitelinks.
Sitelinks cannot be edited. If you need to change sitelinks, create a new set and assign it to the ad.
A set of sitelinks undergoes review only when it is assigned to an ad. See Result of reviewing extensions.
A set of sitelinks can be deleted only if it is not assigned to any ads. To get a list of ads that a particular set is assigned to, use the Ads service.
