An official campaign has been endorsed by the moderators of that subreddit as an official product representing their community.
Official campaigns may receive complimentary ads on reddit for the subreddit they are associated with. These ads are a bonus provided if there are impressions available, but the number of views they get may vary, and we can't guarantee they will be shown at all if a subreddit's ad space has already been sold. These ads will be automatically generated by our system, so there is no additional work for you to do.
At this time, official campaigns must be charitable.
