245% Revenue Growth for a French Fashion Label
A premium French fashion e-commerce was running Google Ads with a 1.2x ROAS — effectively losing money. Their campaigns had no structure, poor match types, and zero conversion tracking.
In 3 months, revenue from paid search grew by 245% while ad spend increased by only 40%.
68% Drop in Cost Per Lead with Meta CAPI
A B2B SaaS company was struggling with Meta Ads after iOS 14 decimated their tracking. Reported conversions were down 60%, campaigns were optimizing on bad data, and CPL had tripled.
Event Match Quality Score improved from 2.
#1 Rankings for 40 Keywords — Local SEO Domination
A multi-location aesthetic clinic had zero organic visibility. Their website was technically broken, had no local SEO setup, and was losing patients to competitors ranking for their exact services.
Within 6 months, the clinic ranked #1 for 40 target keywords.
What Clients Say
The metrics are important. But the relationships are what I am most proud of.
“May transformed our entire digital marketing operation. Before working with her, we were running Google Ads with a 1.4x ROAS and had no idea where our sales were actually coming from. Six months later, our ROAS is 5.2x and we have full attribution visibility. She is the best investment we have made in our marketing stack.”
“After iOS 14, our Meta campaigns fell apart. May implemented the full CAPI setup and rebuilt our audiences using first-party data. Our CPL dropped 68% in 6 weeks. What impressed me most was her ability to explain complex technical concepts to our non-technical board — she is both a strategist and a communicator.”
“May is the rare expert who understands both the technical implementation side AND the business strategy side. She built our entire GA4 measurement framework, set up GTM properly for the first time, and created dashboards that our entire marketing team actually uses daily. Our data quality went from chaos to clarity.”
