An ecommerce audit is a structured review of where a store loses revenue between the ad click and the repeat order. It covers tracking, traffic quality, product pages, offer, checkout and retention. Paid audits from specialist agencies usually cost a few thousand dollars; some agencies, including ours, run a free written audit.
What an ecommerce audit covers
A useful audit follows the money from the first click to the second order and asks the same question at every step: where are shoppers leaving, and what is that worth? It is not an SEO crawl or a design critique, although it touches both. The output is a ranked list of fixes with an estimated revenue impact for each.
| Area | Key questions | Typical finding |
|---|---|---|
| Tracking and data | Are orders, add-to-carts and checkout steps counted correctly? | Duplicate or missing purchase events |
| Traffic and landing pages | Does each paid click land on a page that repeats the ad’s promise? | Cold traffic sent to the homepage |
| Site, speed and product pages | Can shoppers find, understand and choose a product quickly on mobile? | Price, shipping and proof below the fold |
| Offer and pricing | Do the shipping threshold, bundles and discounts earn their margin? | A threshold set below average order value |
| Cart and checkout | Where do shoppers drop, and why? | Surprise costs and slow express pay |
| Retention and post-purchase | What happens after the first order? | No post-purchase offer, weak second-order flow |
Ad accounts get their own review. For the paid side, see our guides to the Facebook ads audit and the Google Ads audit.
Start with tracking and data
Every other finding depends on the numbers, so a good audit checks them first. In the audits we run, half the stores we see are optimising on bad numbers. Common faults include purchase events counted twice, add-to-carts missing from the cart drawer, and ad platforms and analytics that disagree by more than anyone has noticed.
Shopify stores had extra reason to check this year. According to Shopify’s help center, the additional scripts section in checkout settings has been view-only since August 28, 2025, and August 26, 2026 was the deadline for non-Plus stores to upgrade their Thank you and Order status pages. Any tag that lived in additional scripts had to be rebuilt as a pixel, and a tag rebuilt both as an app pixel and as a custom pixel counts every order twice.
The audit should reconcile four weeks of orders across Shopify, GA4 and each ad platform, with Shopify’s order count as the reference. Until those agree within a known margin, every later recommendation is a guess. Fixing this first also speeds up the rest of the audit, because every later estimate uses the same numbers.
Traffic, landing pages and product pages
Next, the audit follows paid clicks to where they land. In our audits, mismatch between the ad’s promise and the page is the cheapest fix with the biggest lift, and it creeps in because ads change far more often than pages. With the cost of a single website visit up 30% over three years, according to Contentsquare’s 2026 benchmark, every mismatched click costs more than it used to.
Product pages come next. Benchmarks help separate a page problem from a checkout problem. Littledata’s 2026 study of Shopify stores puts the median add-to-cart rate at 6.6%, falling to 5.3% on mobile. A store well below its category on add to cart has a product page or traffic problem; our guide to add to cart rate explains how to read it.
Speed belongs in this section too. Deloitte’s study for Google found a 0.1 second improvement in mobile speed lifted retail conversion rates by 8.4%. The audit should name the specific scripts and assets slowing the pages that take paid traffic, not just report a score. It should also flag apps that load on every page but are used on only one.
Cart, checkout and offer
The late funnel is where the most money leaks. Baymard puts the average documented cart abandonment rate at 70.22%, and Littledata’s store-wide benchmark shows a median checkout completion rate of just 47% among sessions that start checkout.
Extra costs are the main cause. In Baymard’s research, 40% of US shoppers who abandoned did so because extra costs such as shipping, tax and fees were too high, 18% because the site wanted them to create an account, and 12% because they could not see or calculate the total cost up front. An audit should check whether shipping cost appears before checkout, and whether express payment sits high enough on mobile to skip the forms. Baymard estimates the average large ecommerce site can gain a 35.26% increase in conversion rate through better checkout design alone.
The offer is part of this review. An audit should check whether the free shipping threshold sits sensibly above average order value, whether bundles and multi-packs exist, and whether discounts are doing work or giving margin away. Offer changes are some of the highest-value tests a store can run: for Momentous, one shipping test added $2 million in profit.
Retention and post-purchase
Most audits stop at the order confirmation. That misses the cheapest revenue in the store. A shopper who has just paid is the most willing buyer you will ever have, and a post-purchase offer cannot lose the order it follows.
The audit should check what happens on the thank-you page, whether a post-purchase upsell is running, how email capture works, and how quickly the second order comes. For subscription products, it should review the subscription buy box, because what is selected by default and how the saving is framed decide take rate.
This is where some of the biggest results come from. For Salt & Stone, conversion testing and post-purchase offers added $7 million in annual revenue. Post-purchase upsells alone added about 10% to average order value for Optimize Minerals. Neither shows up in an audit that treats the order as the finish line.
For repeat-purchase products, the audit should also measure how long the second order takes and what share of first-time buyers come back at all. Those two numbers decide what a new customer is really worth, and therefore how much the store can afford to pay to acquire one.
What an ecommerce audit costs
Paid audits are often priced as a fixed project. Conversion optimization agencies on Clutch commonly list $100 to $199 an hour, with minimum projects from $1,000 to $50,000 and up. At those rates, an audit that takes 20 to 40 hours of senior time lands between about $2,000 and $8,000. Larger stores, multiple storefronts and custom builds push it higher.
| Option | What you get | Best for |
|---|---|---|
| Self-audit with a checklist | Your own review against a list such as our CRO audit checklist | Teams with analytics skills and time |
| Free agency audit | A written review of the main leaks and the first tests to run | Stores deciding whether to hire help |
| Paid audit | A deeper review, often with session analysis and customer research | Larger stores or complex stacks |
What matters more than the price is the deliverable. A good audit names each problem, shows the evidence, estimates the revenue at stake from your own numbers, and ranks the fixes. If it ends with a generic checklist and a sales pitch, it was a brochure. Our guide to CRO pricing covers what the work after the audit should cost.
How to get value from the audit
Before the audit, share read-only access to Shopify analytics or GA4 and, if you run them, ad accounts. Add a short note on what feels wrong and any changes made in the last 90 days. The more context the auditor has, the less time goes on rediscovering what your team already knows.
After the audit, act on the top three findings within two weeks, not all of them at once. Fix tracking first, ship the quick wins that need no test, then test the bigger changes in order of revenue at stake. Our post on Shopify conversion rate optimization sets out a testing order that works for most stores.
Our free CRO audit covers twelve areas, from analytics and traffic match to post-purchase and test readiness. You get a written report within five working days, from read-only access, with the revenue impact of each leak estimated from your own numbers. Andrew Cowan runs every audit himself and walks you through it on a 30-minute call, and you keep the document whether or not you hire us. If you would rather have the fixes run for you, see how our ecommerce CRO program works.
