Reddit has announced it is launching native promoted posts in its mobile apps, as reported by Marketing Land. The in-app promoted posts will behave like a standard Reddit post, and will be available as early as next week.

In an email to advertisers, Reddit said that the app now accounts for 41 percent of all time spent on Reddit, with 330 million monthly users accessing the site via mobile devices. Of these users, those who are logged in spend 30 percent more time per day on the site than those who log in via desktop. About 80 percent of those who access Reddit on mobile do not visit the site on dekstop.

The mobile ad posts should integrate into the existing Reddit experience, with the ability to upvote, downvote, and comment. Previously, users were not able to comment on mobile ads. Advertisers will be able to target their ads based upon user interest, subreddit, location, device, and time of day.

Reddit’s mobile promoted posts will start for iOS on Monday, March 19th, and will come to Android within the next few weeks.
