Zintego: Cutting CPA by 73% While Scaling Spend
Case Study • GOOGLE Ads • DIGITAL PRODUCT SCALING
Zintego is an invoicing and billing platform offering invoice templates, receipt templates, estimate templates, and an online invoice generator designed to help businesses create professional invoices quickly. The product serves users actively searching for ready-to-use billing tools, making Google Ads a high-potential acquisition channel. Zintego came to us with strong demand but inconsistent performance. While traffic volume was healthy, conversion rates were low and acquisition costs fluctuated, making it difficult to scale spend profitably. They needed a more structured Google Ads strategy that could capture high-intent searches and convert them efficiently.
The Challenge
The primary challenge was intent alignment and inefficient campaign structure. Zintego's account was targeting broad keyword coverage without clear segmentation between templates, generators, and billing tools. This resulted in wasted spend, inconsistent performance, and low conversion efficiency. In addition, the connection between search queries, ad messaging, and landing pages was weak, causing users to land on pages that didn't fully match their intent. The result was high CPA and limited ability to scale.
Our Strategic Approach
We implemented a structured Google Ads turnaround focused on intent segmentation, relevance, and conversion optimisation. First, we rebuilt the account around core search categories such as invoice templates, receipt makers, estimate tools, and generators, allowing for clearer targeting and better budget control. Next, we refined keyword coverage to prioritise high-intent searches while eliminating low-converting traffic. We also improved ad messaging and landing-page alignment so users consistently found exactly what they searched for. Finally, we introduced continuous optimisation across search terms, bidding strategy, and conversion tracking to scale performance while improving efficiency.

Why It Worked
The turnaround came from aligning Google Ads directly with user intent. By structuring campaigns around how users actually search, we reduced wasted spend and focused budget on high-converting traffic, cutting cost per acquisition by 73%. Improved query-to-page alignment increased relevance and lifted conversion rate 3.37x, while continuous optimisation let us scale what worked — growing ROAS from 1.24x to 4.79x along the way. Instead of chasing more clicks, the strategy focused on attracting the right users and converting them at a higher rate.
Final Outcome
Zintego moved from inconsistent paid search performance to a scalable and efficient acquisition channel. With a 506% increase in revenue and a 3.37x improvement in conversion rate, Google Ads became a reliable growth driver. The new structure now supports continued scaling, allowing the brand to capture high-intent search demand while maintaining strong performance.
