Ranking algorithms using unique bucketing identifiers

A non-transitory machine-readable storage medium storing instructions which, when executed, cause a processing device to perform operations comprising:

• identifying a set of content items to be included in a feed displayed to a user of a social network platform in a user interface of the social network platform, wherein the set of content items are hosted by a content sharing platform;
• for each content item from the set of content items, identifying one or more bucketing tokens provided by the content sharing platform, wherein each bucketing token comprises a unique identifier that identifies a plurality of content items as being associated with a group of users of the content sharing platform that have similar interests;
• and
• improving a ranking score of each content item from the set of content items that has at least one bucketing token matching a bucketing token associated with the user of the social network platform, wherein the set of content items to be included in the feed displayed to the user in the user interface of the social network platform is to be modified based on improved ranking scores of respective content items from the set of content items.

A system comprising:

• a memory;
• and
• a processing device, coupled to the memory, to:
• identify a set of content items to be included in a feed displayed to a user of a social network platform in a user interface of the social network platform, wherein the set of content items are hosted by a content sharing platform;
• for each content item from the set of content items, identify one or more bucketing tokens provided by the content sharing platform, wherein each bucketing token comprises a unique identifier that identifies a plurality of content items as being associated with a group of users of the content sharing platform that have similar interests;
• and
• improve a ranking score of each content item from the set of content items that has at least one bucketing token matching a bucketing token associated with the user of the social network platform, wherein the set of content items to be included in the feed displayed to the user in the user interface of the social network platform is to be modified based on improved ranking scores of respective content items from the set of content items.
