Systems and methods of adopting data across different sites are disclosed. In some example embodiments, a data adoption system configures a first networked site to adopt data from one or more other networked sites, detects new data on the other networked site(s), with the new data being associated with a data item on the other networked site(s), determines that a record of the data item is being stored on the first networked site, and stores the new data from the other networked site(s) on the first networked site in association with the data item based on the detecting of the new data on the other networked site(s) and the determining that a record of the data item is being stored on the first networked site.
