When CAC climbs, the usual answers are more ad creative, a redesign, or a test another brand swore by. Each one costs months and budget, and none of them tells you where your store loses buyers.
SplitBase's CRO audit answers that first. It's a two-week review of your store's data that shows where visitors drop off and why they leave. Every finding comes with what to do next: a fix your developers can ship, or a change worth A/B testing.
A conversion rate optimization audit is only as good as its data. We start with your tracking, then follow your shoppers from the ad to the order confirmation.
Does the page match the ad that sent them, and how does each campaign’s traffic behave once it lands?
What new visitors click first, and how fast they reach your best sellers.
Filters, sorting and product cards, and the point where shoppers stop comparing and leave.
The buy box, offer and price display, reviews, and the objections the page leaves unanswered.
Shipping costs, free-shipping thresholds, upsells, and the step where orders drop.
Subscription take rate, entry offers, and the path to a second order.
We check GA4 events and revenue against Shopify before we read a single report.
Mobile and desktop, new and returning visitors, each channel and each top landing page.
Mobile load times, app bloat, and errors by device and browser.
Every test we run comes out of three kinds of research. Your CRO audit covers the first one in depth.
In your audit
Behavioral data from GA4, Shopify, heatmaps and session recordings that shows where revenue leaks.
When you continue
Customer surveys, reviews and competitor research that show how shoppers see your brand and what holds them back.
When you continue
A/B tests that confirm which changes make you more money.

Example. Yours is built from your own data.
An audit deck you keep. Every finding comes with the data behind it, a screenshot of the page and what we’d change. A recent one ran 38 slides.
A fix-now list. Tracking gaps, bugs and clear wins your developers can ship without a test.
A test plan. Hypotheses for your first 90 days of A/B tests, with the page, the metric and the traffic each test needs.
A live walkthrough. 60 to 90 minutes with your team to go through the findings and answer every question. Bring whoever signs off.
You give us read access. We do the rest.
Day 1
Kickoff. A short call on your goals, your numbers and what you’ve already tried. Then read access to GA4, Shopify and your heatmap tool.
Week 1
Data. We check your tracking, then break down your funnel by device, channel, new and returning visitors, and landing page.
Week 2
Analysis. We watch heatmaps and recordings on the pages that leak the most, then decide what to fix and what to test.
End of week 2
Walkthrough. We present the findings live for 60 to 90 minutes and leave you with the deck.

Many audits hand you a list of best practices. Tests built on another brand’s best practices often lose, because nobody checked them against your customers.

A CRO audit is a review of your store’s data that shows where visitors drop off, why they leave, and what to fix or A/B test to win that revenue back. At SplitBase it takes about two weeks and ends with a live walkthrough of every finding with your team.
It covers your tracking, your funnel by segment, and every step from the ad to the order: landing pages, homepage and navigation, collection pages, product pages, cart and checkout, subscriptions and post-purchase. We use GA4, Shopify data, heatmaps and session recordings. You get an audit deck, a fix-now list, a test plan and a live walkthrough.
Ours is one fixed fee that we share on a free 30-minute call, and it comes off your first month if you start a CRO program within 60 days. If the walkthrough isn’t useful, we refund it. Across the market, what an audit costs depends on how deep it goes: a heuristic review of a few pages costs far less than one built on your analytics, behavior data and customer research.
About two weeks, from the day we get access to your data to the walkthrough. If you don’t have a heatmap tool yet, we set up Microsoft Clarity first and let it collect data, which adds time.
A short kickoff call and read access to GA4, Shopify and your heatmap or session recording tool, such as Microsoft Clarity, Hotjar or Heatmap. Ad account access is optional. Nothing on your site changes during the audit.
A UX audit asks whether shoppers can use your site without friction. A CRO audit covers that, ties each finding to your data and your revenue, and ends with a plan of fixes and A/B tests. A UX review is one input into a CRO audit.
The audit is the diagnosis: what to fix and what to test. A CRO program acts on it every month with research, design, copy, development, QA and A/B tests. Many brands start with the audit to see how we think before they commit to a program.
Yes. We write the fix-now list for your developers, and the test plan works with your A/B testing tool, such as Intelligems. Some brands ship the quick fixes themselves and hand us the tests.
No. The audit focuses on behavioral data from GA4, Shopify, heatmaps and recordings. Customer surveys, review mining and competitor research happen in the CRO program, where they feed the next round of tests.
No. We audit Shopify and Shopify Plus stores. Plus gives you more control over checkout, so the checkout recommendations depend on your plan.
Fixes don’t need a test, so they help at any traffic level. A/B tests need volume. For each test in the plan we note the traffic it needs, and we flag where your traffic is too low to test and a straight change makes more sense.
If you can, yes. The audit shows what already converts and what loses money, so the new site keeps what works. Redesigns that skip this step often look better and sell the same.
You choose. Your team can act on the findings, or we can turn them into a CRO program. If you start a program within 60 days, the audit fee comes off your first month.
Yes. Conversion Blueprint is the name we’ve used for our CRO audit on sales calls. Same scope, same price and the same credit.
Our CRO strategists, the same team that runs testing programs for brands like Dr. Squatch, Hyperice and Kiehl’s. Together they’ve run more than 10,000 A/B tests on ecommerce stores.
In about two weeks you’ll know what to fix, what to test, and the data behind each one. Bring whoever signs off to the walkthrough.
