Caraway Increased Revenue 46% With Performance Max
When Google decided to sunset Smart Shopping campaigns in favor of Performance Max, OuterBox was ready. We used a phased transition to help Caraway protect its strict return on ad spend goals while moving campaigns that accounted for nearly two-thirds of its Google Ads delivery. Comparing the first two weeks of Performance Max deployment with the final two weeks of Smart Shopping usage, Caraway increased conversion volume 37%, ROAS 31%, and revenue 46%.

The Context
Caraway is a popular maker of high-quality home cookware. As an eCommerce business, Caraway frequently used Google’s Smart Shopping campaigns to advertise its wares.
Google planned to sunset the Smart Shopping campaign format by the end of August 2022, with Performance Max as the determined replacement. The transition would be automated, but advertisers had an opportunity to transition manually in advance. We considered Performance Max campaigns beneficial for improving delivery and increasing shopping reach.
Because Smart Shopping campaigns accounted for nearly two-thirds of Caraway’s Google Ads delivery, a smooth and structured transition was vitally important for maintaining the client’s strict return on ad spend goals. This was especially pressing because we believed Google was likely to favor Performance Max delivery over Smart Shopping during the transition period. The longer we waited, the harder it might become to achieve Caraway’s monthly revenue expansion goals.
Our Solution
To transition Caraway’s campaigns, we needed to aggregate all necessary creative assets and determine the most effective campaign structure under the new format. We determined that a phased approach to the Performance Max transition would limit the likelihood of a negative impact on delivery, given the volatility that often occurs during automated transitions.
We worked closely with the Caraway team to get all the necessary image, video, and text creative to form the campaigns. Then we leveraged product-type keyword data from their search campaigns to form custom audiences for each asset group. This would better inform the Performance Max campaigns about who to target with each type of creative.
We rolled out our transition plan, beginning with a lower-volume campaign to study the differences between Smart Shopping and Performance Max in detail. We used insights from the initial transition to inform the subsequent campaign updates. These learnings allowed us to properly allocate budget across the old and new campaigns during the transition period, controlling for volatility despite significant upheaval in the account.
Adhering to our phased approach, we began transitioning campaigns two months before the automatic transition deadline, giving Caraway’s account significant time to benefit from the lack of other advertisers using Performance Max. Finally, we created separate Performance Max campaigns based on different product types. This allowed for custom creative, well-defined audience signals, and more effective control of bids and budgets.
