This document describes how you can consolidate two Quantcast tags with different IDs (p-codes) into one tag. For example, if you wanted to aggregate reporting on a network of blogs, while still allowing individual blogs owner to have full control (public visibility settings, site descriptions, access controls, etc) over Quantcast profiles, the technique shown here is useful.
Publishers wishing to consolidate two Quantcast tags can use a modified version of the standard Quantcast tag as shown below. In this example, the first set of
_qoptions could belong to the blog network operator, whereas the second could belong to the individual blog owners.
Labels in each set can be the same, different, or omitted all together. Blogs that are not measured via Quantcast can obtain their own ID (p-code) by creating a free account.
The result of the above tag would be traffic being equally attributed to the sample account IDs p-12345abcde and p-678910abcde , both of which would contain the label ‘Technology’. This occurs in a single request to Quantcast.
