A/B testing for Shopify

A CRO team made of AI agents.

They find why shoppers leave your product page, build the fix in your theme, check it with simulated buyers and watch every live test around the clock. You approve what goes live.

How it works

Watch one fix go from finding to winner.

Each AI agent hands the work to the next. Step through one fix, from the first finding to the shipped winner.

Step 1 · Researcher agent

Finds why shoppers leave

10 to 50 simulated buyers, matched to your customers, shop your live product page and say where they stopped, in their own words.

Example finding and numbers, for illustration.

Test twice

Simulated buyers test the fix first.
Your shoppers see it second.

An A/B test learns whether a change works from weeks of live traffic. eLLMo checks it with simulated buyers first, before a single shopper sees it.

Stage 1 · Simulated buyers

The buyers who found the problem shop the fix.

What you can test

New sections and new words, on your product page.

Page tests

Add what buyers said was missing. Your current page stays as it is while the test runs.

  • Reviews block
  • Size guide
  • Materials and care
  • Shipping promise by the button

Copy tests

Same product, same URL. When you promote the winner, eLLMo writes it to the product and keeps your old copy.

  • Title
  • Product details
How eLLMo compares

Custom fixes on your store, without hiring anyone.

An agency builds custom code for you, on a retainer. A testing app is self-serve, and your team still does the work. eLLMo's AI agents do that work for you, inside a self-serve app.

Where A/B testing options sitAcross: cost, rising to the right. Up: how much of the work is done for you. eLLMo sits top left: low cost, most of the work done for you. CRO agencies sit top right: they do the work, on a retainer of $2,000 to $15,000 a month. Variant sits in the middle. Shoplift and JavaScript A/B tools sit low: your team brings and builds the test.Cost →Work done for you →eLLMoAI agents find, build and check the fix,ready to ship the same dayCRO agenciesDo the work for you, on a retainer$2,000 to $15,000 a monthVariantAI writes each test as JavaScriptthat edits the page in the browserShopliftRuns the test you bringJavaScript A/B toolsYour team finds and builds each test

Built into your theme

Drawn by ShopifyThe fix is real theme code. Shopify draws it like the rest of your store. Nothing rewrites the page in the browser.
No rebuild after the winThe page shoppers saw is the page that ships. No developer ticket to rebuild the winner.
Counted from your ordersRevenue per visitor, from your Shopify orders matched to the version each shopper saw.
Your current page stays safeIt is not edited during a test. Pause, stop or roll back at any time.
