Challenge
Reducing costs without slowing growth in a booming education market
In an increasingly competitive education sector, the UOC faced a clear scenario: each lead was more expensive and competitors were multiplying. With the increase in acquisition costs and channel saturation, it was necessary to change the digital strategy.
The goal was not only to reduce the CPL, but to do so while maintaining volume, improving lead quality and achieving greater efficiency throughout the funnel, from the first impact to the final conversion.
Solution
AI, automation and proprietary data to scale acquisition efficiently
The UOC redesigned its Google Ads strategy by combining the technology of the Adsmurai Marketing Platform (AMP) with Gemini's generative AI. This combination made it possible to create creative content tailored to each stage of the funnel, improve personalisation and increase the efficiency of advertising investment.
Specific Pmax campaigns were developed for each educational programme, powered by resources generated by Gemini within AMP. These campaigns were connected to dynamic data feeds, ensuring maximum relevance in the ads.
In addition, mid-funnel actions were activated with audiences based on first-party data (1PD), reinforcing the impact at key moments of consideration and bringing the user closer to the final conversion.
Results
More leads, better quality and greater efficiency with less extra investment
The changes introduced with Gemini and Pmax transformed the UOC's performance. Compared to Q1 2024, the results spoke for themselves:
-
🔥 +122% in conversion volume.
-
💸 -45% in CPL, allowing them to capture more for less.
-
📈 +253% in conversion rate, increasing the quality of leads.
All this with an investment increase of just +21%, demonstrating the improvement in efficiency. In addition, Pmax optimisation had a positive effect on Search, where CPL was also reduced by -43%.
The results speak for themselves. At the UOC, we would like to highlight Adsmurai's excellent execution of the PMAX campaigns, both in terms of their strategic approach and tactical implementation. The PMAX campaigns have undoubtedly been a key driver of the campaign's overall performance. In a highly competitive and demanding environment, Adsmurai's expertise, combined with close and constant collaboration with our team, has been instrumental in successfully achieving our objectives.
