Insights on Performance Marketing and AI

Not textbook theory. Frameworks, decisions and learnings built from +$5M MXN/mo in managed investment, three telecom operators and fourteen years of real operations.

What I build, what I learn

Performance Marketing
How to build campaigns that scale without breaking CAC

Frameworks and operational decisions on Meta Ads, Google Ads, bid optimization, campaign structure and controlled scaling. All built from real operations with budgets from $800K to $3.3M MXN/mo.

  • Why CPL is not the right KPI for telco
  • Platform ROAS vs MER: when to use each
  • How to scale without the algorithm losing optimization signals
  • Campaign structures that last: not those that work the first week

Applied AI Marketing
AI that reduces operational time and improves decisions

Not AI to do what you already did faster. AI to do what you couldn't do before: massive creative performance analysis, audience fatigue prediction, segmentation hypothesis generation and copy optimization at scale.

  • How I use LLMs to analyze 200 ads in 10 minutes
  • AI to generate copy variants the team wouldn't consider
  • Smart automation in Meta and Google: when it helps and when it hurts
  • The risk of delegating strategic decisions to AI

Growth Systems
Designing systems that generate revenue predictably

The difference between a campaign and a system is predictability. A system has defined funnels, per-layer KPIs, feedback loops and the ability to scale without reinventing itself. This is how it's built.

  • Why the best campaigns are not an acquisition system
  • How to design a funnel that survives algorithm changes
  • The CRM → platform feedback loop: why it's the differentiator
  • Always On vs seasonal campaigns: how to build both layers

Acquisition Architecture
The technical foundation: diagnosis, tracking and real attribution

Before scaling, you must diagnose. How to audit a system in 48 hours, build tracking that doesn't lie (Pixel + CAPI, enhanced conversions) and detect when the algorithm is learning from the wrong data.

  • How to diagnose an acquisition system in 48 hours
  • Tracking and attribution: the infrastructure nobody builds well
  • How to detect when Meta is optimizing for the wrong event
  • What happens when the CRM doesn't feed signals back to the algorithm

Performance Marketing
How to scale Meta Ads without breaking CAC

The costliest mistake in paid media: raising budget on an architecture that doesn't scale.

CAC vs CPL: why optimizing CPL destroys the business in telecom

The dashboard metric is not the one that matters. This distinction has cost margin to many carriers.

Generative AI in performance marketing: what works and what doesn't

The real applications that moved KPIs on $5M MXN/month of managed spend.

How to predict creative fatigue before CPL rises

Ads fatigue 5-7 days before CPL shows it. Here are the early signals.

Growth Systems
What is Always On and why seasonal campaigns don't replace it

70% of revenue in pharmacy retail does not come from Hot Sale or Christmas.

Growth Systems
The real difference between a campaign and an acquisition system

A campaign gets spent. A system scales, learns and improves its CAC over time.

How to diagnose an acquisition system in 48 hours

The audit process I run with every new client before touching a single campaign.

Tracking and attribution for performance marketing: the foundation nobody builds properly

Without clean tracking there is no system. Pixel, CAPI, enhanced conversions, GTM: the infrastructure that matters.

Performance Marketing
Por qué el CPL barato destruye la operación de ventas

CPL $12 + 4% conversion = CAC $300. The arithmetic is obvious. Why operations keep falling for it.

Arquitectura
How to spot when Meta is optimizing for the wrong event

The dashboard shows conversions climbing. The business isn't growing. Four signals that confirm the diagnosis.

Growth Systems
The real problem with always on campaigns in retail

Baseline budget gets reallocated in season. The algorithm loses the model. Re-entry after the season is always more expensive.

Arquitectura
What happens when the CRM stops feeding signal back to the algorithm

Meta: 500 leads. CRM: 180. Sales: 11 customers. Each gap is a different problem with a different solution.

Growth Systems
The difference between scaling budget and scaling architecture

Doubling the budget without changing the architecture doesn't scale the system — it stresses it. CAC confirms it by week 3.
