A growth audit is a structured review of the revenue levers of an online consumer brand (paid acquisition, email, conversion rate, and retention) to identify where revenue is leaking and which fix has the highest impact. Unlike a brand audit, which examines perception and positioning, a growth audit examines numbers: ROAS, CAC, email revenue share, repeat-purchase rate, and LTV. The output should be a prioritised action plan, not a scorecard.

That's the definition. The rest of this post covers what a good one actually includes, what it isn't, and how to tell a real audit from a disguised sales pitch.

Growth audit vs brand audit vs marketing audit

These get conflated constantly. If you search "growth audit" you'll mostly find brand-audit content. The distinction:

Brand audit. How your brand is perceived: identity, positioning, customer sentiment, competitive image. Qualitative-heavy. Useful, but it won't tell you why revenue plateaued.

Marketing audit. A broad review of marketing activity: channels, campaigns, messaging, often including brand elements. Wide, and usually shallow per channel.

Growth audit. Narrow and quantitative on purpose. It looks only at the levers that move revenue for a consumer brand, and ranks fixes by expected revenue impact. The test of a good one: every finding has a number attached.

What a good growth audit covers

For a D2C or B2C consumer brand, six areas:

  1. Paid acquisition. ROAS and CAC by channel, creative fatigue, audience saturation, ad-to-landing-page alignment.
  2. Email. Which core flows exist and which are missing, email's share of total revenue, segmentation, list health.
  3. Conversion. Checkout friction, mobile UX, pricing presentation, funnel leaks from first click to purchase.
  4. Retention. Repeat-purchase rate, churn signals, win-back and replenishment mechanics, AOV.
  5. Free→paid (apps and subscriptions). Time-to-value, activation milestones, upgrade triggers, paywall design.
  6. Measurement. Whether the numbers above are even trustworthy: MER vs platform-reported ROAS, new vs returning revenue split, LTV against CAC payback.

What a growth audit is not

It is not a website teardown, a free "SEO scan" generated by a tool, or a discovery call with a slide deck. The tell-tale signs of a disguised pitch: no access to your actual numbers, findings that apply to any brand, and a deliverable that only makes sense if you buy the retainer.

The three properties of a real audit

It's built on your data. Its recommendations are prioritised by revenue impact. And the output is usable without hiring the auditor.

Who needs one, and who doesn't

Useful when a brand is doing roughly $10K–$500K/month and growth has plateaued despite active spend. That's when the constraint is usually one specific lever, not effort. It's also the right first step before choosing between a fractional growth marketer and an agency: the diagnosis tells you which model you actually need.

Not useful pre-revenue or in the first months of trading: there's no data to audit yet, and the constraint is traction, not optimisation.

FAQ

How long does a growth audit take?

Formats vary. Ours is a 60-minute live review of your numbers followed by a written roadmap within 24 hours. Longer consulting engagements exist; length doesn't determine quality. Data access does.

What should a growth audit cost?

Anywhere from free (as an entry offer, like ours) to five figures from consulting firms. Judge it by the three properties above, not the price.

What do I need to provide?

Access to your real numbers during the review: ad accounts, email platform metrics, store analytics. An audit without your data is a guess.
