Amazon PPC vs Walmart Connect: How to Allocate Budget

They are not the same system

Amazon’s advertising ecosystem is mature and highly competitive. Walmart Connect is younger and, in many categories, cheaper per click — but its volume is lower. That difference matters more than a simple cost-per-click comparison.

Amazon typically offers more refined targeting and faster feedback; Walmart often offers lower competition and a channel where early, disciplined investment compounds as the marketplace grows.

A simple allocation framework

Start from the channel’s strategic role, not from a fixed percentage.

• Fund defending the revenue you already have on each marketplace first.
• Then fund growth where the channel is a strategic priority for the next two quarters.
• Keep a defined share for testing new keywords, categories and campaign types.
• Review monthly: shift budget toward the channel producing profitable growth, not just volume.

Signals that you should shift budget

• Rising cost per acquisition on one channel without a matching conversion improvement.
• Walmart Connect volume growing while efficiency stays healthy — a sign to scale.
• Listings on one channel underperforming organically, which limits how hard ads can work.
• Seasonality where one marketplace sees structurally stronger demand.

Do not skip the prerequisites

Advertising amplifies what already exists. If listings, catalog data and pricing are weak, more spend simply buys more expensive traffic. Fix the fundamentals before scaling budgets — it is the single most common reason ad spend underperforms.
