Case Study
From roughly 14000 to 42000 dollars in monthly sales
Growing a supplement business while focusing acquisition on stronger customer economics.
Four15 helped a specialty supplement brand develop its paid acquisition program during a period of substantial business growth. The supplied sales chart shows monthly total sales rising from approximately $14,000 in February 2021, before the engagement, to approximately $42,000 in September 2021, roughly three times the starting level.
The work combined Google Shopping, product campaigns, creative testing and website improvements. As the engagement progressed, the team used repeat-purchase behavior, customer lifetime value and product margins to decide where to focus acquisition spend. Google emerged as the stronger channel.

Four15 began work in March 2021 with an existing Shopify store and active advertising. The initial review found that only eight of the site’s 15 products were in Google Merchant Center, with one of those disapproved. The team also needed to connect the product catalog, organize campaigns around purchases and improve the shopping experience.
Early changes included Google-Shopify integration, product and bundle updates, Facebook campaign restructuring and product-feed work. The team introduced a slide-out shopping experience for individual products and worked through issues affecting bundles.
The later notes show substantial sales into 2022: January recorded $35,846 in net sales, February $29,355, and March reached $36,936 by March 30. These figures establish a higher business scale well beyond the initial campaign rebuild, although sales fluctuated and did not increase every month.
The team compared purchase performance across channels and shifted budget from Facebook to Google in May 2021. Smart Shopping became a major acquisition campaign. By the September 2021 review, Google reported $16,314.83 in attributed revenue on $7,560.08 in spend, a 2.16× return.Â
In early 2022, Four15 moved the shopping structure to Performance Max, separating the main multivitamin from other products so the team could manage their targets independently. Later notes describe steadier conversion volume after the split and additional tests for individual products.
The most popular product was not automatically the most valuable acquisition opportunity. Lifetimely reporting showed meaningful differences in first-order value, repeat purchasing and accumulated customer sales by first product purchased. The team used those differences to identify products worth testing more aggressively.Â
In April 2022, this became a specific test plan for products with higher margins but lower sales volumes. Ads were tailored to individual products and sent shoppers to the relevant product page. This connected campaign decisions to product economics instead of relying only on overall return on ad spend.
Four15 tested product-focused images, customer review videos, new-product creative and promotional ads. The team reviewed performance by creative, paused weaker ads and refreshed stronger concepts. Shopping feeds, product approvals and seasonal promotions were managed alongside campaign changes.
Website work included the slide-out cart, product-page and landing-page improvements, and mobile and desktop consistency. The team identified broken product links and missing landing-page images; ads to the affected landing page were paused while the issue was addressed.
Later analysis showed a large gap between Google and Facebook in reported new-customer acquisition. The team continued testing Facebook, but the June 2022 handoff recommended keeping it paused and retaining the most efficient Google campaigns. The resulting structure was deliberately simpler for the client to manage.
Monthly total sales roughly tripled from the pre-engagement low to the 2021 peak, with several later months still exceeding $30,000 in net sales. Four15 supported that expansion through paid acquisition, product strategy and improvements to the path to purchase. The strongest documented channel contribution came from Google; the broader sales increase also reflects returning customers and other business channels.
