A method and apparatus for enriching metadata are disclosed. For example, the method implemented via a processor monitors metadata associated with a first webpage of a plurality of webpages, the first webpage having been determined to be similar to a second webpage of the plurality of webpages, detects a change to the metadata associated with the first webpage, determines whether the change to the metadata associated with the first webpage invokes an update to a metadata associated with the second webpage, and processes the update of the metadata associated with the second webpage when the change invokes the update to the metadata associated with the second webpage.
