Method and apparatus for identifying common interest between social network users

A non-transitory computer-readable medium storing instructions that, when executed by at least one processor, cause a computer system to:

• detect, by a social networking system, a first user of a social networking system interacting with a first content object;
• determine a first keyword phrase by conducting a reverse keyword search utilizing the first content object as a search input such that inputting the first keyword phrase into a foreword keyword search identifies the first content object as a forward search result;
• associate, by the social networking system, the first keyword phrase with the first user based on the first user having interacted with the first content object;
• identify one or more users of the social networking system that are associated with keyword phrases correlated to the first keyword phrase as candidate users;
• and
• provide a list of one or more of the candidate users that includes the first keyword phrase and a selectable option to communicate with the one or more of the candidate users.
