The progressive delivery of targeted secondary content may include determining that primary content requested from a particular distribution point of a distributed platform includes a first tag to integrate targeted secondary content as part of an initial presentation of the primary content, and a second tag to integrate targeted secondary content outside the initial presentation. The progressive delivery may further include modifying the primary content by replacing the first tag so that the primary content and targeted secondary content for the initial presentation (e.g., third-party content associated with the first tag) are provided from the particular distribution point without accessing a third-party content provider, while targeted secondary content outside the initial presentation (e.g., third-party content associated with the second tag) may be selected and provided by one or more third-party content providers as originally specified in the primary content.
