  • 10x+ ROI — And We Keep Pushing

    10x+ ROI isn't the finish line — it's where we start looking for more. We never settle for stable results. Every campaign is optimized for growth, every dollar is pushed harder, and every win gets scaled. Average is the enemy.

  • Global Market Exposure

    Your buyers don't shop in one place. Seller Splash runs full-service campaign management across Google, Meta, TikTok, Bing, and Walmart, and tailors the strategy to how buyers behave on each one. Walmart is live in our AI tools now, with more platforms on the way.

  • AI That Creates, Optimizes & Scales

    Our AI doesn't just monitor — it builds campaigns from scratch, optimizes every bid in real time, and scales aggressively when something works. It pushes for growth 24/7. With Walmart live now and more platforms coming, the AI keeps finding new ways to grow your business.

  • Years of Operating Experience

    Trends come and go. Fundamentals win. Seller Splash has managed millions of dollars in advertising across Google, Meta, TikTok and Walmart. We've seen algorithm changes, platform crashes, and failed hype cycles. As a result, we make fewer mistakes, optimize faster, and devise strategies based on what actually works, rather than what is popular this week.

  • Custom E-commerce Marketing

    Seller Splash builds custom E-commerce marketing strategies for each client based on their margins, categories, lifecycle stages, and growth goals. We design every campaign around your business reality, not recycled agency tactics.

  • Expertise Across Every Channel

    Google Ads, Meta, TikTok, Bing, plus SEO and Answer Engine Optimization for the AI search era. We don't dabble — we run each channel deliberately and make them work together across the full buyer journey, from Google search to ChatGPT recommendations to checkout.
