How it works

Fix the leak nearest the money first.

No big-bang redesign, no 40-page audit. Just a calm, repeatable loop: measure, find the biggest leak, fix it, check it, and move on to the next one.

Step one · about 2 weeks

The Ad-to-Sale Diagnostic

Numbers first. Before anyone touches your site, we figure out whether your ad spend can pay back at all — and what it would take.

Book a diagnostic
  1. Before we start

    Checklist & access

    You share a few numbers (margin, average order, ad spend) and read-only access. We check your tracking is telling the truth before we judge anything.

  2. Week 1

    Your numbers

    We work out what a customer is worth to you, the most you can pay to get one, and the ad return you need to break even.

  3. Week 1–2

    The path from ad to sale

    We pull 90 days of ad and store data and follow your top 3 ads on a phone, all the way to checkout, the way a customer would.

  4. Week 2

    Find the leak

    We work through each step in order — click, page, bag, checkout — and stop at the first one that’s clearly broken. Plus a quick look at email, Google and two competitors.

  5. End of week 2

    Walkthrough

    A recorded call where we go through your scorecard, top 5 fixes, 90-day roadmap and “not yet” list. Then you decide what’s next.

Step two · every month

The monthly loop

Advisory and Growth Partner both run on the same simple monthly rhythm. One goal per 90 days; everything else goes on the “not yet” list.

  1. 1

    Measure

    We refresh your scorecard against your break-even cost per customer and your starting point.

    Us

  2. 2

    Spec

    We write two ready-to-build fixes — what to change, why, exactly how it should look, and how we’ll know it worked — with a short video for each.

    Us

  3. 3

    Build

    Your person builds the fixes, ideally within 14 days. On Growth Partner, we build the small ones ourselves (up to 4 hours a month).

    You (or us, on Growth Partner)

  4. 4

    Verify

    We check each change on your live site — phone and desktop — and confirm tracking still works.

    Us

  5. 5

    Report

    A one-page report and a 45-minute call: what changed, what moved, what didn’t, and which leak is next.

    Together

  6. A typical month

    • Week 1 · numbers, 2 fix specs, monthly call
    • Weeks 2–3 · your team builds; quick questions by email
    • Week 3 · we check what shipped
    • Week 4 · one-page report, pick the next leak

“Experiments” here are mostly careful before-and-after changes with a written reason, not lab-grade A/B tests. Every readout says how confident we are — and unshipped fixes never count as tested.

What we need from you

Your part is small, but it matters.

Advice only works when it ships. Here’s what makes the difference.

A few numbers

Your rough product margin, average order value, how often customers come back, and monthly ad spend. Ballpark is fine to start.

Read-only access

Shopify (or your platform), your Meta ads account, Google Analytics, and your email tool. Nothing we can break.

A person to build

Someone — staff, your ad person, or a freelancer — with a few hours a month to make changes. Less on Growth Partner.

You, once a month

The owner or manager on the monthly call, and approving fixes within about a week so they don’t stall.

Timeline

Your first 90 days

  1. Weeks 1–2

    Diagnostic and walkthrough.

  2. Month 1

    Fix the leak closest to the money — often where your top ads send people.

  3. Month 2

    Re-measure. Move to the next leak once month one’s fixes are live.

  4. Month 3

    Compare honestly against your starting point and decide together: keep going, change course, or stop.

What we don’t do

Staying in our lane keeps the advice honest.

We’d rather do one thing well. If you need help with any of these, ask — we’ll point you to good people.

  • Run your ads, make creative, or change budgets — we brief your ad person instead
  • Redesign or rebuild your site
  • Install new apps or build big new features
  • Write all your copy, shoot photos, or upload products
  • Run SEO content or link-building programs
  • Promise a specific sales lift

Start with two weeks and a clear answer.

Start with a two-week diagnostic. You’ll know what a customer is worth to you, where the sale is slipping away, and the five fixes that matter most — whether or not you keep working with us.
