Recommendations for shareable links to content items stored in an online content management service. In one aspect, a recommendation is sent to a first user to create and share a shareable link to a content item with a second user. The content item to share via a shareable link is identified as one that is currently not shared by the first user and that has one or more characteristics in common with a “popular” content item as determined by monitoring the popular content item for a threshold number of requests to access the popular content item via a corresponding shareable link to the popular content item.
