The Problem

What usually
goes wrong

Scaling across European markets is harder than it looks. These are the three patterns I see most often.

💸

Wasted Ad Spend

Campaigns that look beautiful in reports but quietly hemorrhage budget. Clicks that never become customers.

🌍

Lost in Translation

Google Translate isn't localization. Native speakers can tell instantly when ad copy feels generic. And they leave.

👻

Agency Ghosting

Month one is magic. By month three, you're talking to someone new. The specialist who won your trust has disappeared.

Ad Copy

Rewrote the ad headlines.
Sales return jumped 57%.

Ad Strength Myth

"Excellent" Ad Strength.
Zero Conversions.

Every asset group scored "Excellent". Google's highest rating. The campaign generated 9,653 impressions, 79 clicks, and exactly zero in conversion value.

Mafer, Digital Advertising Strategist
About

Meet Mafer

I've spent 8+ years in digital advertising, managing everything from single-brand accounts to large multi-country setups across Europe, North America, and Latin America.

Before going independent, I managed Google Ads campaigns for an agency handling premium e-commerce and luxury brands across multiple markets. That gave me cross-industry pattern recognition most solo consultants simply don't have.

What makes me different? I speak your customers' language. Literally. Native Spanish, fluent English, fluent French. When I write ad copy for your French market, it's not a translation. It's written by someone who thinks in that language.

She is a complete paid advertising specialist; strategically and operationally strong, but also very technically skilled. She has extensive experience with multilingual cross-border campaigns. What characterises her most is that she treats projects as if they were her own business. Nothing is too much for her. In short, I highly recommend her.
