Goals
Oneisall, a China-based smart pet product brand, wanted to increase customer engagement across European countries. They aimed to launch full-funnel advertising campaigns spanning multiple product lines and seasonal promotions but were constrained by slow and costly creative development processes.
Commissioning photographers and graphic designers for each product and locale was expensive and time-consuming—resulting in delayed campaign launches and a limited ability to test new concepts quickly. Oneisall wanted to A/B test different creative elements such as backgrounds, product settings, and styles, but the high production costs made generating variations for statistically significant testing impractical. Maintaining consistent brand aesthetics across hundreds of products without extensive manual oversight was also a challenge.
Oneisall wanted to accelerate the production of high-quality, on-brand image creatives while reducing costs and enabling data-driven creative optimization. This led them to explore AI-powered image generation capabilities in Amazon Ads as a transformative solution for their advertising workflow.
Approach
Oneisall implemented a comprehensive full-funnel advertising strategy using AI-powered image generation across Sponsored Brands, Sponsored Products, and display ads to drive brand lift and new-to-brand sales. The strategy centered on using AI-powered image generation capabilities to create a dynamic, data-driven creative engine that could rapidly produce high-quality, tailored creative assets at scale.
At the top of the funnel, Oneisall focused on brand storytelling through Sponsored Brands ads. The team developed premium, on-brand image creatives to establish trust and recall. They created master prompts incorporating brand guidelines (e.g., color palette, lighting, and mood) to generate a cohesive creative library that maintained consistent brand aesthetics across campaigns. This helped Oneisall rapidly develop seasonal (e.g., holiday decorations) and themed image assets while maintaining unified messaging—essential for building brand awareness and attracting customers early in their journeys.
For their mid-funnel campaigns, Oneisall prioritized maximizing click-through rates (CTR) by conducting extensive A/B testing of Sponsored Products ads. The team used AI-powered image generation to produce numerous creative variations for each product. They tested different backgrounds, product-in-use scenarios, and contextual elements, then ran these variations in parallel campaigns to identify top performers based on performance data. This data-driven creative selection process helped Oneisall scale effective visual themes across product campaigns and reduce customer acquisition costs.
To resonate and drive conversions, creatives must feel relevant to each segment's motivations—a difficult challenge to overcome at scale through traditional production methods. Oneisall used AI-powered image generation to develop a large quantity of tailored display ads creatives for specific audience segments. By pairing tailored creatives with interest-based audience targeting for their lower-funnel campaigns, they significantly increased relevance and conversion rates.
