Building high-ROAS ecommerce search campaigns in Google Shopping and Amazon Ads

In the ever-evolving world of ecommerce, paid search has emerged as one of the most effective growth channels for businesses. Unlike other advertising platforms, paid search offers a unique combination of high intent and detailed data, enabling ecommerce retailers to convert search queries directly into revenue. Google Shopping and Amazon Ads, in particular, capture high-intent demand and provide the necessary data to scale these campaigns efficiently. The key to success lies in organizing these campaigns to act on the insights they offer.

Paid search excels for ecommerce because it leverages two critical advantages: intent and data. Firstly, Google and Amazon are search-driven environments. When a customer searches for a product, they are explicitly stating their intent to purchase. This eliminates the need for inference, audience modeling, or interrupting users mid-scroll. As a result, paid search provides a direct response to a customer's query, making it an ideal channel for ecommerce.

Secondly, both Google Shopping and Amazon Ads offer keyword-level revenue data, which is rare among advertising platforms. Retailers can track which search terms generate sales, their conversion rates, and the associated costs. Amazon goes even further by providing clearer and more direct revenue visibility at the product and category levels. This level of transparency creates a powerful feedback loop. By identifying search terms that drive revenue, retailers can reallocate their budgets toward higher-converting queries, improving their return on ad spend (ROAS) over time. On Amazon, this loop extends further, as improved conversion rates can enhance organic rankings, thereby reducing future acquisition costs.

To maximize the effectiveness of search campaigns, retailers must build multi-funnel structures that cater to different campaign types, settings, and bidding strategies. The architectures outlined below utilize wide-net, low-cost discovery campaigns to map the full search landscape, then funnel high-intent, proven converters into dedicated performance campaigns with optimized bids. This approach results in stronger ROAS, improved rankings, and more scalable growth.

Discovery campaigns serve as the foundation for understanding the search intent and landscape. These campaigns use broad match keywords and low bids to capture a wide range of queries. The goal is to gather data on which terms resonate with customers and drive sales. By analyzing this data, retailers can identify high-performing terms that warrant further investment.

Once high-performing terms are identified, retailers can create dedicated performance campaigns focused on these specific keywords. These campaigns employ more precise match types and optimized bids to capture the highest-intent traffic. By allocating budget to these high-converting terms, retailers can improve their ROAS and drive more sales.

In addition to optimizing keyword selection and bidding strategies, retailers must also consider the unique features of each platform. For example, Amazon's data transparency allows retailers to track revenue at the product and category levels, providing valuable insights into which items are driving sales. This information can be used to adjust product listings, improve inventory management, and refine marketing efforts.

Google Shopping, on the other hand, offers features like product ads and rich snippets that can enhance visibility and trust with consumers. Retailers should leverage these tools to improve their search presence and drive more clicks and conversions.

Success in building high-ROAS ecommerce search campaigns on Google Shopping and Amazon Ads requires a strategic approach to campaign architecture, keyword selection, and bidding strategies. By utilizing discovery campaigns to map the search landscape and funnel high-intent traffic into dedicated performance campaigns, retailers can harness the power of paid search to drive sales and grow their businesses. The key is to continuously analyze data, adapt strategies, and leverage the unique features of each platform to maximize ROAS and scale effectively.
