E-commerce: 40% Lower CPA at Scale
The challenge
A premium home goods brand was spending $85K/month on Google Ads with diminishing returns. Their ROAS had dropped from 3.2x to 1.5x over 6 months due to rising CPCs, poor audience targeting, and landing pages that didn't convert. They were considering cutting their paid budget entirely.
Our strategy
Account restructuring
We reorganized their Google Ads account from 3 bloated campaigns into 12 tightly themed campaigns with single keyword ad groups for their top performers. This immediately improved Quality Scores from an average of 4.2 to 7.8.
Shopping feed optimization
We rebuilt their product feed with optimized titles, descriptions, and custom labels. We implemented a tiered bidding strategy based on product margin and historical conversion data.
Landing page overhaul
We created dedicated landing pages for each product category with lifestyle imagery, trust signals, and streamlined checkout flows. Page load time dropped from 4.2s to 1.8s.
Smart bidding & audience layering
After accumulating sufficient conversion data, we transitioned to Target ROAS bidding with audience layering — remarketing lists, similar audiences, and in-market segments.
The results
Within 3 months, CPA dropped 40% while ad spend remained constant — meaning significantly more customers at the same budget. ROAS climbed from 1.5x to 4.2x. Over 6 months, the campaigns generated $1.8M in revenue from $430K in ad spend. The client increased their paid budget by 60% based on the improved efficiency.
"We went from questioning whether paid ads were worth it to making them our most predictable revenue channel."
