The challenge and
the strategy

When Genkii came to Growzz Media in early 2024, they weren't starting from scratch. They were an established company in the solar energy sector with a solid customer base, strong reviews and a commercial process that was already working. The challenge wasn't to rescue a business, but to accelerate one that already had traction.

The objective was clear: grow lead volume while maintaining —and improving— lead quality, and thereby increase total sales without driving up the cost of acquisition.

To achieve this, we designed a two-pronged strategy. On one side, optimisation of Google Ads and Meta Ads campaigns, refocusing targeting and messaging to attract leads with higher purchase intent. On the other, we incorporated Email Marketing as a nurturing and closing tool, working on communication with captured leads to improve conversion rate throughout the commercial process.
