Methods, systems, and apparatuses, including computer programs encoded on a computer storage medium, for providing data related to conversion paths. In one aspect, a plurality of conversion paths are received. Each conversion path includes one or more user interactions that include a plurality of dimensional data. A priority sorted list of dimensions is received and dimensional data is selected from each user interaction based on the sort list of dimensions. Each conversion path is converted into a dimensional path, and each dimensional path includes dimensional elements that corresponds to user interactions of the conversion path. Each dimensional element comprises the selected dimensional data from the corresponding user interaction. The plurality of dimensional paths are aggregated together based upon the number of dimensional elements within each dimensional path and the dimensional data of the dimensional elements. Reports can be generated using the aggregated dimensional data.
