Abstract: A computer-implemented system and method allow an analyst and/or automated system to dynamically adjust the allocation of marketing results among a plurality of categories of marketing items such as channels and/or campaigns. According to various embodiments, a continuous control element, such as a slider, is provided, allowing the analyst to specify an allocation at any point along a continuum. A displayed report is updated substantially instantaneously in response to the analyst's manipulation of the control element, so as to provide dynamic, real-time feedback. According to other embodiments, adjustments to allocations can be made automatically. The displayed report can indicate, for example, revenue, order allocation, average order value (AOV), profit, return on investment, or any other quantitative result(s), and can update these results substantially instantaneously in response to changes in allocations. Graphical and/or textual representations of the quantitative results can be presented and updated.
