Back to original languageAbout Mathieu
I have been supporting e-commerce businesses and brands on Google Ads and Meta Ads for nearly 12 years.
Specifically, my job is not to generate traffic. It's to make your campaigns profitable.
Over time, I've seen many accounts. And the observation is often the same: they spend, but they don't really scale.
Today, the real lever is no longer targeting. It's Ad creative (UGC, videos & static).
If the ad doesn't capture attention, doesn't create desire, doesn't trigger action... the algorithms won't work miracles.
On my end, I work methodically, quickly, and simply:
1. we establish a clear strategy,
2. we produce the advertising assets (UGC/video/Static),
3. we test quickly,
3. and we manage with concrete figures (CPA, MER, LTV).
AI helps a lot, but without a framework, it can also accelerate losses.
I mainly work with small and medium-sized e-commerce businesses. Pragmatic people who want results, not slides.
We talk frankly. We test. We adjust.
Generally, we work together for 3 months.
Then, either you internalize, or we continue.
No dependency. No unnecessary layers.
If you have already invested in Ads and feel there's a plateau to overcome, I can help you break through it.
A quick 15-minute call to understand your challenges,
then I'll give you clear feedback with recommendations and a quote.
Simple, fast, concrete. Talk to you soon :)
Mathieu.
