Google Ads for E-Commerce — ROAS optimization at scale.

E-commerce Google Ads live or die on margin management: Shopping campaigns, Performance Max, and search must be calibrated against your actual product margins, not average ROAS. QuantForge HQ deploys agents that build Google Ads infrastructure around your margin architecture — protecting high-margin SKUs, suppressing low-margin products, and optimizing LTV cohorts rather than blended ROAS.

WHY E-COMMERCE GOOGLE ADS IS DIFFERENT

Performance Max Cannibalizes Branded Search

PMAX campaigns serve across all Google surfaces including branded search — often cannibalizing traffic you would have gotten at near-zero cost organically. Without brand exclusions and campaign priority controls, PMAX inflates reported ROAS by claiming credit for returning customers.

Margin-Blind ROAS Optimization

Standard ROAS targets apply equally to your 70% margin bestseller and your 12% margin clearance item. Agents that optimize against blended ROAS push budget toward high-AOV, low-margin products instead of high-margin, lower-AOV ones.

Feed Quality Determines Shopping Performance

Google Shopping campaigns are only as good as your product feed. Missing attributes, inconsistent titles, and poor image quality degrade ad relevance, increase CPCs, and prevent your products from appearing for high-intent shopping searches.

New Customer Acquisition vs. Retention Blending

Standard campaigns serve ads to existing customers returning to buy again — inflating ROAS with transactions that would have happened organically. True new customer CAC is often 2–3× reported CAC when existing customer transactions are excluded.

WHAT WE RUN FOR E-COMMERCE CLIENTS

01

Margin-Weighted Bidding Architecture

Product groups segmented by actual margin. High-margin SKUs get aggressive ROAS targets; low-margin products excluded or managed separately. Bidding strategy optimizes for gross profit, not revenue.

02

Performance Max Configuration & Controls

PMAX set up with brand exclusions, asset group segmentation by product category, audience signals from your highest-LTV customer cohorts, and search theme guidance to prevent broad waste.

03

Product Feed Optimization

Agents audit and optimize your feed: title structure (primary keyword + product type + brand), attribute completion, image quality scoring, and price competitiveness vs. Shopping auction benchmarks.

04

New Customer Acquisition Campaigns

Separate campaigns with customer match suppression for existing buyers. New customer ROAS targets set independently. True acquisition cost calculated against first-order margin, not blended account ROAS.

05

Dynamic Remarketing & Cart Abandonment

Dynamic product ads serve exact SKUs abandoned in cart or viewed without purchase. Agents manage bid multipliers by recency tier: 1-day abandoners vs. 30-day window shoppers.

06

Shopping Auction Intelligence

Agents monitor Shopping auction insights weekly — Impression Share, Overlap Rate, and Outranking Share by product category. Budget concentration shifts toward categories where you can outbid competitors on high-margin searches.
