CRO Agency Case Study
Sunology

Sunology is a leading solar panel and electronics retailer, providing high-quality eco products for the luxury market.

Throughout 2020, we optimized Sunology's lead generation process, identifying the most profitable audiences and testing different kinds of advertising content. In addition to auditing their acquisition strategy, we provided wireframes for a number of key product and landing pages, improving the website's lead-to-conversion rate.

By the end of 2020, we had reduced the cost-per-acquisition by over 65%. Additionally, we increased revenue-per-customer by incorporating upsells at key points in the customer journey.

CRO Agency Case Study
Piscine Center

Piscine Center is the largest supplier of swimming pool equipment in Europe.

Between 2016 and 2017, we studied visitor behaviour on the site's home page in order to increase both sales and revenue per customer. Using a combination of heat maps, session recording and analytics, we identified a bottleneck in the site's navigation structure.

In the summer of 2017, our A/B tests produced a conversion rate uplift of + 14.01%. At the same time, revenue per customer increased thanks to the introduction of targeted cross-selling and bundled purchases.

Our approach begins with data. We work with clients to build up a picture of who their customers are and how their website works. Our team conducts heat-mapping, session recording and segmentation procedures. But numbers don't make decisions...
