Guillaume was a decisive lever for accelerating our SEA growth. Already strong in SEO, we needed expert management to develop our campaigns across several training themes. From strategy to execution, Guillaume managed everything: account structuring, A/B tests, clear reporting, weekly KPI tracking, and measurable results. He quickly understood our persona and customer segments, which allowed for optimized targeting. Results: Increased CTR, thanks to refined messages and keywords. Decreased CPC, through better-controlled Quality Score. Increased leads, with a clear reduction in CAC. We highly recommend Guillaume Adrian and his long-term support. Working with a true SEA expert makes a difference. We will call on him again for our future campaigns and their ongoing monitoring.
