Growing the business, or just harvesting it?

Account ROAS counts returning customers as new growth. I run Google and Meta ads on aMER, new customer revenue against total spend. Fourteen years, done personally.

What actually moves the number that matters

Google and Meta Ads

Search, Shopping, Performance Max, Demand Gen, YouTube and full funnel Meta, run as one system instead of channels bidding against each other. Microsoft and TikTok where they earn their place.

Product Feed Management

The feed drives roughly 70% of Shopping performance, and most accounts leave it on defaults. Merchant Center audits, disapprovals fixed at the source, and AI feed enhancement that rewrites titles and attributes against proven Shopping frameworks.

Server-Side Tracking

Most accounts bleed 20 to 40% of conversions to broken tracking. Blotout and EdgeTag, server-side CAPI, Consent Mode v2, and new versus returning splits, so aMER is something you can actually measure.

Not sure which of these you need?

Talk to the person who runs the account

Not an account manager, not a junior

AI trained on my playbooks, not generic prompts

Every audit follows my methodology

Most agencies bolt ChatGPT onto 2020 workflows and take whatever the model guesses. I built a system on Claude Code trained on fourteen years of my own SOPs, so audits, search term classification and negative mining follow a tested process every time.

AI where it compounds, not where it demos

Feed rewrites against proven Shopping frameworks, creative generation on my own offer angle frameworks, daily automated account health checks, and custom scripts deployed per account. The work that repeats is the work AI should own.

AI for your team, on your data

I also help in-house marketing teams and C-suite implement AI properly, on your SOPs and your data instead of another tool that collects dust. Audit the sprawl, turn playbooks into agents the team uses daily, and train people to move faster without losing brand voice.

Another year of trusting account ROAS is expensive.
