If youâve ever felt like marketing advice is just recycled nonsense from one âguruâ to the next, youâre not alone.

Most marketers obsess over the technicalitiesâad formats, button colors, audience insightsâwhile completely missing the actual point: driving traffic that converts into sales.
Thatâs why I wrote Math-Rules and Formulas in Marketing, a book that ditches the fluff and gives you the core principles that make advertising (especially on Facebook) actually work.
And no, this isnât another âultimate Facebook Ads guideâ stuffed with vanity metrics and generic tips you could find on a LinkedIn post. This book is the guide I wish I had when I startedâstraight to the point, tactical, and backed by real-world business experience.
I started learning about Facebook Ads in 2018 while working in an oil factory in Buenos Aires. Great salary, solid career path, and the full support of the companyâs president. But I hated every second of it.
So, I started a side hustleâAssedare EcolĂłgica, an ecological cleaning company. Problem? I had zero budget, no marketing team, and only the hours outside my 9-to-5 (plus extra overtime) to figure out how to get clients. I needed results, fast.
What did I do? I ignored the noise and focused on what actually makes ads profitable. No blog posts, no social media content calendars, no 2,000-word SEO articles. Just a strong offer, clear messaging, and a strategy designed to make sales.
Two months later, we had 81 clients. I quit my job. (A bit prematurely, but thatâs another story.)
This book is built on those principlesâthe ones that made a struggling side hustle into a real business. And whether youâre spending $500/month or $500K/month on ads, these principles apply at every level of marketing.

Marketing is not about trends, hacks, or blindly following âbest practices.â Itâs math, logic, and psychology. And when you understand the rules that govern it, you can apply them anywhereâwhether youâre running a local business or a billion-dollar brand.
Math-Rules and Formulas in Marketing is still in the works, but if you want to be the first to get a copy when it launches, sign up below.

1. Clear > Clever
Your ads donât need to be witty or âcreative.â They need to be understood.
Formula:
Understanding = (Clarity / Cleverness) ^ Audience Receptiveness
The clearer your message, the easier it is to turn attention into conversions. If your audience has to think about what youâre selling, youâve already lost.

Most businesses copy their competitors, who are just copying their competitors. The cycle never ends, and nobody innovates. If you copy them, youâre just replicating their mistakes.
Formula:
Differentiation = Innovation – Copying
If you want to stand out, stop looking sideways and focus on offering something better.

People donât have time for mediocre ads. If your content isnât interesting or valuable, itâs invisible.
Formula:
Engagement = Interest Ă Value
High-value but boring content? No engagement. High-interest but zero value? Useless. You need both.
In math, you canât divide by zero. In business, you canât create growth without prioritizing your customers. Every decisionâpricing, branding, positioningâshould be built for them.
Formula:
Trust = Care Ă Confidence
The more you care about solving their problems, the more theyâll buy.
