Solution

Hello Bello partnered with Teikametrics, a Walmart Connect Partner Network Tech Partner, to optimize their ad performance.

Strategy and Tactics

Hello Bello leveraged AI-driven campaign technology from Teikametrics to help boost performance across its Sponsored Products and Sponsored Brands campaigns, delivering strong results.

  • Targeted ad types: Sponsored Products promoted all Hello Bello products with automated and manual bidding, while Sponsored Brands focused on high-priority items, such as diapers.
  • Optimized bidding: Tiered bidding (broad > phrase > exact) prioritized high-performing terms with aggressive bids. Manual campaigns shifted from branded to generic keywords to drive category traffic.
  • Placement targeting: Low-performing placements were excluded. Single Image Group placements and app-focused bids received aggressive bid multipliers to maximize ROAS and boost conversions.
