Serrano Digital Verified Company

Most agencies start by asking which platform you want to advertise on. We start somewhere else: margin, average order value, and how often a customer comes back. Those three numbers decide how much you can actually afford to pay to acquire someone. Until you know them, picking a channel is guesswork with someone else's money.

Serrano Digital is a performance marketing and growth agency for ecommerce, founded in 2022 in Córdoba, Argentina, by Walter Fernández, who brings over 7 years in the industry. We work with SMBs and online stores across Argentina and Latin America.

How we work:

Business before channel. We define what a customer is worth over time and what you can pay to get one. Only then do we decide where the budget goes.

Fix the funnel before pushing it. If the store doesn't convert or customers never come back, more budget only makes the same leak more expensive.

One specialist per channel. No generalist rotating between accounts: each discipline is run by someone who does only that.

We measure to the sale, not to the click. Tracking is built before the first campaign goes live. If a number can't be tied to a sale or a qualified enquiry, it doesn't drive decisions.

We test on ourselves first. Every method we sell, we run on our own agency before offering it. That is how our AI search visibility service started: we measure every month whether ChatGPT, Perplexity and Gemini recommend us, using the same questions we later run for clients.

We publish a benchmark built on real data from our own portfolio, over 100 million Argentine pesos in ad spend analysed across seven months, because an agency should be able to show its own numbers and not just ask for yours. Published case ratios: 13.51x ROAS sustained over a quarter for a supplements ecommerce, 6.25x for a niche brand, and more than 4,000 qualified enquiries for a consultation-driven business.

We run ads on Meta, Google, TikTok and Mercado Libre, email marketing and CRM, and work mostly with Tiendanube stores. Certified Google Partner, verifiable in the official directory under ID 2065464005.
