1Why a Foundation Roadmap Matters

Most ecommerce brands fail at Google Ads because they skip the foundation. They launch campaigns without proper tracking, targeting without strategy, and optimize without benchmarks.

The Foundation Problem

Common failure patterns:

  • Launch campaigns day 1 without conversion tracking
  • Copy competitor strategies without understanding them
  • Scale before proving profitability
  • Make changes based on 2 days of data

The 4-Week Solution

This roadmap provides:

  • Week-by-week actions with clear deliverables
  • Milestone checkpoints before moving forward
  • Realistic expectations at each stage
  • Foundation that supports long-term scaling

Calculate Scaling Room:

7Common Problems and Solutions

Troubleshoot these common issues during your 4-week foundation build.

Problem 1: No Impressions

Symptoms: Campaigns approved but not showing ads.

Causes & Solutions:

Key Takeaways

A proper 4-week foundation prevents costly mistakes and enables sustainable scaling

Week 1 is infrastructure only—tracking, feed, research—no campaigns yet

Week 2 launches 3 core campaigns (Brand Search, Non-Brand Search, Shopping) with simple bid strategies

Week 3 focuses on search term refinement, negative keywords, and initial optimizations

Week 4 refines structure, sets up remarketing, and prepares for scaling

Resist optimizing in Week 1-2; data collection requires patience before meaningful decisions

The goal of month 1 is learning, not profit—profitable scaling comes from applying those learnings

Frequently Asked Questions

Experienced advertisers can compress to 2-3 weeks, but the stages remain the same. The main time-gated element is data collection—you need 7+ days of data before making optimization decisions. Rushing the data collection phase leads to decisions based on noise, not signal. Compress setup days, not learning days.
