Strategic Approach Behind the Results

This campaign was built for profitability from day one.

1. High-Intent Search Strategy

Campaigns structured around commercial buying intent, not broad traffic terms.

2. Negative Keyword Discipline

Continuous filtering to eliminate non-buying traffic and reduce wasted spend.

3. Geographic Refinement

Targeting aligned to profitable delivery regions.

4. Budget Reallocation

Spend shifted toward top-converting products, ad groups and search terms.

5. Conversion Rate Alignment

Ad messaging aligned tightly with landing page experience to increase conversion rate.

6. Data-Driven Scaling

Budget changes were performance justified rather than arbitrary.

Total Impact on the Business (April–December 2025)

Total Google Ads Revenue: $129,401
Highest total store revenue: $46,659 (October)
Acquisition cost reduced month after month

This demonstrates sustainable ecommerce growth driven by structured Google Ads management.
