Google Ads for ecommerce, structured around profit, not just revenue

Many store accounts chase revenue and lose money on low-margin products. We structure Google Ads around your margins, best sellers and stock, so growth stays profitable.

In short: Google Ads for ecommerce combines Shopping, Performance Max and Search campaigns to sell products online. As an ecommerce PPC agency, Web Zodiac groups products by margin and performance, fixes the product feed, tracks purchases with values, and sets return-on-ad-spend targets from your real margins.

Why margin matters more than ROAS

A 4x return on ad spend sounds good, but it can lose money on a product with a thin margin and make a fortune on one with a high margin. We set targets per product group from your real margins, so Google's bidding chases profit, not just revenue.

Platforms we work with

Shopify, WooCommerce and most store platforms that can send a product feed to Google Merchant Center and purchase data to Google Ads and GA4.

What is ecommerce PPC?

Ecommerce PPC is pay-per-click advertising for online stores, mainly Google Shopping, Performance Max and Search ads, where you pay per click and measure success in sales and return on ad spend. As an ecommerce PPC agency, we manage the product feed, campaigns and tracking together, because each one affects the others.

Often, when the product feed is clean and purchase tracking includes values. Many stores run it alongside Shopping or Search campaigns for more control.

What ROAS should my store target?

Your break-even ROAS depends on your margins and costs. We calculate it per product group, then set targets above it.

Do you manage Google Merchant Center?
