Seido Knives Buy Box Optimization & PPC Scaling
When Seido Knives’ 8-Piece Knife Set (ASIN: B0B3ZY44YY) was handed over, the product was underperforming due to low sales, high ACOS, and unstable Buy Box ownership caused by multiple MAP-violating sellers.
We started with a full account and competitive analysis to identify inefficiencies across pricing, fulfillment, listing content, and advertising structure.
The strategy focused on stabilizing Buy Box control while improving both traffic quality and conversion performance. We implemented a dynamic pricing strategy to compete with MAP sellers, while optimizing both FBA and FBM offers to increase Buy Box share and delivery competitiveness.
At the same time, we fully optimized the product detail page by improving titles, bullet points, backend keywords, and overall messaging to better highlight product value, craftsmanship, and real use cases.
A+ content was redesigned to strengthen brand authority and trust, while SEO improvements expanded keyword coverage and improved organic visibility. PPC campaigns were restructured to eliminate wasted spend and focus on high-converting keywords.
By aligning pricing, fulfillment, ads, and listing optimization, we created a system where the product could compete effectively — and scale consistently.
