In one embodiment, a method includes receiving, from a client system associated with a first user of the online social network, an indication of a check-in at a geographical location by the first user, generating multiple reaction-cards based at least in part on the check-in, each reaction-card being associated with a structured query referencing the geographical location, each reaction-card including one or more search results matching the structured query associated with the reaction-card. The method also includes sending, to the client system, in response to receiving the indication of the check-in, instructions for presenting one or more of the reaction-cards, wherein the reaction-cards are presented in ranked order based on a relevance of the structured query associated with the respective reaction-card to the geographic location.
