Free before/after CRO evidence check for 3 Shopify stores

I’m the co-founder of UX Agent, and I’ve spent nine years working on Shopify CRO. I’m offering a free, fixed-scope before/after evidence check for three Shopify stores planning one meaningful theme, app, product-page, cart or checkout change.

This is for merchants who want to know whether the change improved the buying path, not just whether the page still loads.

What I’ll review:

  • one funnel transition connected to the change;
  • mobile versus desktop behavior;
  • a small set of anonymized sessions before and after;
  • the difference between observed facts, likely explanations and what still needs validation.

What you get: a one-page note with the strongest evidence, the main uncertainty and the next test. This is not a redesign and there is no guaranteed conversion lift.

To participate: install UX Agent – Checkout Replay before the change, enable the App Embed / checkout data, and collect enough relevant sessions on both sides: UX Agent ‑ Checkout Replay - Find why shoppers drop off and what to improve first. | Shopify App Store

It is free to install and does not require Shopify Plus. Reply publicly with your store category, primary market, planned change/date and the one funnel transition you want checked. Please do not post passwords, customer details, payment information or private session links. Third-party payment-provider internals are outside the review unless separately verified.

Hi @Icey.Lane
I really like the fixed-scope approach here, especially the distinction between observed facts and likely explanations.

One thing I’d be careful about with before/after CRO checks is attributing the change to the theme/app update when other variables changed at the same time.

For example, if mobile conversion improves after a product-page change, it’s tempting to call the change successful. But traffic source, device mix, campaign activity, product availability, pricing, discounts, or even the type of shoppers entering the funnel can shift between the two periods.

I’d personally want the evidence check to separate:

1. What changed → the actual UX/funnel behavior
2. What moved → conversion/drop-off/session behavior
3. What else changed → traffic, device mix, offers, campaigns, inventory, etc.
4. What can actually be attributed to the release → and what still needs validation

That would make the one-page report much more useful than simply showing that the numbers went up or down.

Also curious: when you compare the before/after sessions, do you have a way to segment them by device + traffic source + funnel step, or is the comparison mainly based on the overall session set?

That distinction could make the evidence a lot stronger.
