A DTC growth audit should show you where revenue is leaking, what to stop right away and which fixes to make first. It should be built from your own sales, margin and stock data rather than from what each ad platform reports. An audit that cannot do that gives you little basis for deciding what to change. A useful audit also lets you assess an agency before signing. You see how the agency interprets your own numbers and which actions it recommends.
The audit matters most when growth has stalled and nobody can agree on why. Paid media, email, the store and search each have their own report. Each can show healthy results while total sales stall.
DTC sales can stay flat while ad spend rises when the extra budget reaches people who would have bought anyway. The same happens when it goes to products with thin margin or low stock, or sends shoppers to a store that loses them before checkout. More creative testing does not address those causes. The audit needs to examine stock, margins and the store too.
Rising media prices make the gap wider. Meta's second quarter 2026 results reported a 12% year-on-year increase in the average price per ad. When each impression costs more, budget spent on returning customers or on products that cannot ship becomes expensive quickly.
New-customer revenue can reveal a problem that total revenue hides. Northbeam's benchmark of its own clients found that new-customer MER, the revenue from new customers for each dollar of ad spend, fell 5.21% in January 2026 even as total revenue grew. A brand can report higher sales and still be buying them less efficiently each month.
Run a growth audit before a decision that is hard to undo, such as a budget increase, a change of agency or a peak season plan. Each of the moments below calls for one.
An audit at one of these points also sets the baseline you will use later to judge whoever runs the plan, measured the way our guide to measuring DTC growth beyond platform ROAS describes.
A DTC growth audit should review each channel against the store's own records, so the findings rest on orders and margin rather than on platform claims. Review the following areas using data from more than one system.
Start with what each channel brought in according to the store, then set it against spend, discounts and fees. Platform dashboards will each claim a share of the same orders, so the totals they report add up to more than the store sold. The audit should reconcile those claims with store orders and show the costs behind each channel.
Split revenue into new and returning customers before judging any channel. Common Thread Collective recommends comparing MER for new customers only with total MER, to see whether a slowdown is an acquisition problem or a retention one. The fix for each is different, and a single blended number hides which one you have.
Check which products the budget actually goes to and compare that with what is in stock and what earns a margin after ad costs. Check last month's best sellers too. Their stock and margins may have changed. The audit should flag spend on items that are about to sell out, already out of stock or too thin on margin to justify the cost.
Miz Mooz shows what fixing this can be worth. In 2023 we set the footwear brand's Google Ads bids and product placement by stock and margin, using our PlayMaker tool and Conative, and Google Ads revenue rose 39.3% on our account reporting. That result covers one channel in one year and does not prove cause by itself.
Review the product, collection, cart and checkout pages for speed, surprise costs and friction. If traffic rises without more orders, check these pages. The audit should name the pages and steps where shoppers leave.
Review automated welcome, browse, cart and win-back flows alongside the campaign calendar. Sending more campaigns to the whole list can wear subscribers out while the flows that earn the most go untouched. The audit should show what each flow earns and which segments it reaches.
Check how the brand's products appear when shoppers search Google or ask ChatGPT, Perplexity or Google's AI Overviews what to buy. Thin product data and missing category pages leave room for competitors in those answers. This part of the audit may be small. It should still show where competitors appear in place of the brand.
You should walk away with a document that tells you where revenue is leaking, what to stop now and what to fix first, in that order. The stop list can be the fastest win, because cutting spend that earns nothing frees budget without any new work.
Each item should name the product, campaign or page involved. Include the evidence, the likely cause, who owns the fix and the result that will show whether it worked. Rank the items by the revenue at stake and how much of the fix sits within your control. Your team should be able to act on the plan whether or not you hire the agency that wrote it.
Three made-up items, not drawn from any client, show the shape such a plan takes.
| Item | Evidence | Likely cause | Owner | Result that shows it worked |
|---|---|---|---|---|
| Stop Shopping spend on sizes that sell out | Spend continues after stock reaches zero | The product feed still lists out-of-stock variants | Paid media | Spend on out-of-stock items falls to zero |
| Show shipping costs before checkout | Shoppers leave at the shipping step | Costs appear only at the last step | Store team | More started checkouts are completed |
| Restart the browse abandonment flow | The flow has sent nothing since a platform change | The trigger broke during the migration | Email team | Flow revenue per recipient returns |
A useful audit works from your data, names specific things and admits its limits. Benchmarks and a budget recommendation alone do not give your team specific work to act on.
The same questions help when you compare agencies more broadly. Our guide on how to evaluate a growth agency for a DTC brand covers what to ask about the team and the contract.
CB/I Digital is a performance marketing and AI search agency for DTC and ecommerce brands, running paid media, email and SMS, conversion, development and search on one plan.

We reply within 1 business day and deliver the audit within 10 business days of access. The document is yours to keep whether or not we work together.
We start with margin and stock to assess which spend is worth keeping. We connect store, inventory and ad data through Conative, the AI platform we built for ecommerce brands. That lets the audit show marketing return by product as well as by campaign.
You can see the full scope of our DTC growth services. Get a clear picture of where your store is losing revenue, which channels earn their spend, and what to fix first with our DTC Growth Audit.
Read access to your ad accounts, analytics, store platform and email platform is enough to start. An export from your finance or inventory system is enough to add margin by product and current stock levels. Those details make the findings more specific. No one needs permission to change anything during an audit.
A PPC audit checks one paid channel, such as account structure, search terms, bids and feeds. A growth audit includes that review and compares every channel with the store's revenue, margin and stock. It can help establish whether the ads are the source of the problem.
No. A good audit is written so your own team, or another partner, can act on it. If an agency makes the findings conditional on a contract, treat that as part of the sales process rather than the audit.
