NMPi and Dune stepped up their paid search strategy in the highly competitive fashion footwear and accessories market. Realizing that over 25% of their conversion paths had more than one touchpoint and over 50% of their sales had at least one interaction with Google Shopping campaigns, they concluded that last click was undervaluing Shopping campaigns.

The team at NMPi got off on the right foot. They refined the structure of the Dune Shopping activity by segmenting the campaigns by device, product type and traffic volume. In addition to this segmentation, the entire Dune paid search account was labelled with five channel groupings: Brand, Brand-Generics, Generics, Product and Shopping; in line with Dune digital business measurement goals.

With these five channel groupings, data driven attribution in DoubleClick Search was set with automated rules in place to automatically apply the channel grouping labels to newly created campaigns. Confident of the right campaign segmentation, comprehensive channel grouping and insights from DoubleClick Search data-driven attribution, the final step was to set a ROAS target bid strategy to deliver 44% ROI improvement YoY for the Dune Shopping activity.

At NMPi, we use DoubleClick Search because features like data-driven attribution make it easy for us to implement market leading strategies with our clients, like Dune London. Combining algorithmic bid strategies with intelligent attribution helped us achieve unprecedented success through Google Shopping. It also streamlined our workload, allowing us to assign resource to the areas where human curation matters the most.

As a business, a priority for 2017 was to drive revenue from new customers at the top of the search funnel. I've been very happy with NMPi's approach, using data-driven attribution within DoubleClick Search to more accurately measure and optimize our Shopping activity to capture these users.
