Case: How Konnect Shop achieved +55% conversions and 22% lower CPC by switching to Producthero CSS
Challenge & goals
With over 20 years of experience in the thermal installation trade, Konnect Shop has built its reputation on technical expertise, reliable service, and customer-first thinking. As the company expanded into e-commerce, its online platform became a key growth driver, serving both professional installers and individual customers across Romania.
However, Konnect Shop operates in a highly competitive market, where cost per click (CPC) can quickly erode profitability. Therefore, the goal was to increase volume and improve ROAS without raising advertising spend. With their campaign strategy already well-optimised, the team saw switching to Producthero CSS as a low-effort, high-impact move that could drive meaningful results quickly.
Approach & Implementation
To scale their Shopping campaigns more efficiently, Konnect Shop partnered with Web Ventures, a full-service digital marketing agency based in Bucharest. Known for their human-centric approach and performance-driven mindset, Web Ventures was already managing campaigns with strong foundations: well-structured accounts, relevant audiences, and optimized product feeds.
The Web Ventures team started looking into Google CSS Partners as a simple way to improve campaign performance without changing the entire setup. After reviewing several options, Producthero CSS stood out due to its simplicity, transparency (no hidden fees), immediate cost-saving potential and additional suite of tools to boost Shopping campaigns.
Instead of making major changes to campaigns, the team implemented one simple yet impactful change: switching Konnect Shop from Google CSS to Producthero CSS. This allowed them to access up to 20% lower CPCs in Shopping Ads while keeping the campaign setup unchanged. No other Producthero tools were used at this stage.
Results
Switching from Google CSS to Producthero CSS delivered immediate and measurable performance gains. Over a one-month comparison period (May 30 – July 4), the results were:
- -22.34% CPC
- +55.58% Conversions
- +31.61% Conversion Value
- +48.15% ROAS
- -24.25% Total Cost
This outcome was achieved without using any additional Producthero tools like Title Optimizer or Labelizer, proving the standalone power of the CSS switch for merchants already running well-structured campaigns.
Next steps
Encouraged by the results, Web Ventures plans to integrate more tools from the Producthero PRO plan to boost their campaigns even further. The next step will be to test Title Optimizer for underperforming SKUs, followed by Labelizer to help segment products based on real-time performance and bidding opportunities.
