For US Shopify and D2C brands

A Shopify CRO agency for US brands that tests what the data points to

Most CRO programs fail because they test opinions. We start from your analytics and your customers: where visitors drop off, what they say stops them, and which fixes are worth a test at your traffic level.

For US Shopify and Shopify Plus stores that means looking closely at the things US shoppers compare before they buy: total price with shipping and sales tax, delivery dates, returns, buy-now-pay-later and wallet payments, and trust signals on mobile.

What US brands need to get right

Price transparency at checkout

US prices are shown before sales tax, so the total jumps at checkout. Showing estimated tax and shipping earlier, or a free-shipping threshold in the cart, is one of the most common tests worth running for US stores.

Delivery promises by date, not days

Shoppers compare against fast national delivery. A specific “Get it by Thursday” estimate, cut-off times and clear holiday shipping deadlines often move conversion more than design changes.

Wallets and buy now, pay later

Shop Pay, Apple Pay, PayPal and BNPL options such as Afterpay, Klarna and Affirm change both conversion and average order value. We test where and how they appear instead of switching them all on.

Subscriptions and repeat purchase

For consumable brands, subscribe-and-save offers, bundles and post-purchase upsells often raise revenue per visitor more than the first conversion rate. We measure tests on revenue, not only on orders.

Accessibility as conversion work

Contrast, focus states, form labels and error messages help every shopper finish checkout, and US stores also face ADA accessibility claims. Accessibility issues found during the audit go into the roadmap with everything else.

Tests sized to your traffic

Each test is planned with the effect it can detect at your traffic, and read with Bayesian analysis. If you do not have the traffic for a test, we tell you and use research-led changes instead.

  1. Problem

    Sales tax and shipping appear only at checkout, so the total jumps at the last step

    Solution

    Estimated tax and shipping, or a free-shipping threshold, shown in the cart and tested

  2. Problem

    Delivery is promised in “business days” while shoppers compare against a dated delivery

    Solution

    A dated “Get it by” estimate with order cut-off times and holiday shipping deadlines

  3. Problem

    Every wallet and buy-now-pay-later option is switched on, with no test of where each one helps

    Solution

    Wallet and BNPL placement tested on both conversion and average order value

  4. Problem

    Checkout forms and error messages that keyboard and screen-reader users cannot get through

    Solution

    Accessibility issues from the audit fixed as part of the same conversion roadmap

Frequently asked questions

How much traffic does a US Shopify store need for A/B testing?

Enough conversions per variant to detect the effect you care about, which usually means a few hundred conversions per variant per test. Below that, research-led changes and qualitative testing are a better use of budget, and we will say so.

Which testing tool do you use on Shopify?

We work with the tool that fits your store, such as Shopify-native testing apps, VWO, Convert or Optimizely, and with theme-level tests where an app is not needed.

Can you test the Shopify checkout?

On Shopify Plus, checkout extensibility allows changes and tests inside checkout. On other plans, most of the gains come from cart, shipping and payment messaging before checkout, which we can test.

How soon will we see results?

The audit and roadmap come first. How fast tests conclude depends on traffic; quick fixes that need no test can ship straight after the audit.

You are based in India: how does the work run with a US team?

Research and test builds happen asynchronously, results are shared in a written report and on a call scheduled to overlap with your working day, and every test is QA’d before launch.
