1,130 Sales, One Campaign.
The Power of Google PMax and how One Campaign Delivered Real E-commerce ROI
How We Scaled an E-commerce Brand from Zero to 1,130 Conversions Using Just One Performance Max Campaign
When we took over this Google Ads account, there was absolutely no ad history zero campaigns, zero conversions, and not a single interaction. Our goal was simple but ambitious: generate real revenue through profitable online sales, and do it only using Google’s Performance Max (PMax) campaign. We weren’t just chasing impressions or random clicks, we aimed to drive high-quality, purchase-ready traffic that would help rapidly grow an e-commerce business from scratch.
Campaign Goals and Why We Chose PMax?
The main objective of this campaign was to start generating tangible conversions that is, online purchases at the most cost-effective possible rate. Along with that, we wanted to build reach and brand presence across all of Google’s ad inventory. That means Search, Shopping, Display, YouTube, Gmail, and Discovery all in one, unified campaign.
What We Did (Our Winning Strategy)
- Delivered rich creative assets including video ads, product feeds, headlines, and CTAs.
- Uploaded first-party audiences like CRM lists and cart abandoners to improve early campaign efficiency.
- Switched to value-based bidding (Max Conversion Value/ROAS) after reaching data thresholds.
- Used the Insights tab daily to monitor top assets, search terms and optimize performance.
- Leveraged seasonality adjustments to increase spend during high-conversion periods.
