We have a few banners on our homepage for promotional campaigns. We would like to measure the total order amount of our customers who clicked on our banner and purchased a product. This way we can see how the banner performs.
You could set up a goal per banner and segment your sales by goals (“Visit converted a specific goal ID”).
You could also set a CustomDimension (Visit not Action) and write the banner identifier in that CusDim and segment by that.
