How it works

Test 3 pages.
Keep the winner.

Your current page is the baseline.

Three new versions run against it. Your page only changes when one of them wins.

  1. 01GENERATE PREVIEWS

    Enter your URL.
    Get 3 previews.

    A product URL feeds three different page designs for gold hoop earrings: dark editorial, social proof with reviews, and minimal.

    Paste your product URL and review three new page designs. Nothing goes live until you start the test.

  2. 02SPLIT TRAFFIC

    Start the test.
    Split your traffic.

    A funnel of visitors splits three ways into the three new page designs: dark editorial, social proof with reviews, and minimal.

    Press start. Traffic splits between your page and the three challengers. Real conversions pick the winner.

  3. 03WINNER → BASELINE

    Use the winner
    as your baseline.

    The dark editorial design stands on a plinth as the winner while the two other designs recede behind it. NEW BASELINE

    The winner goes live as your new baseline. Three new challengers are built from it.

The next round starts from the winner

The one-point effect

Same traffic.Same ad spend.150% more profit.

Ad spend does not change when more visitors convert. So one extra point of conversion lifts revenue 50%, and profit 3× that.

The Darwiny engine

What AI does to your products.

From the first frame to the final fact check, every improvement is built to help the product sell without losing what makes it true.

01Motion

Turn every still into motion.

Product images become on-brand videos, sized for every part of your store.

02Imagery

Make every image worth stopping for.

Lifestyle scenes replace flat catalog shots while keeping the real product at the center.

03Speed

More product. Less waiting.

Lean pages load fast, stay responsive, and protect the attention you already paid to earn.

04Trust

Generate. Then verify.

Catalog-aware checks help flag suspect claims and image mismatches for human review.

05Markets

Any language. Any currency.

Rebuilt in your storefront's own language, with its currency and money format carried through.

Performance context: Akamai retail performance study. Load-time figures shown in the card are illustrative.

Case notes

Most variants lose.The one that wins takes over.

Seven stores, one card each. Of the 72 variants they tried, 50 lost. The quote is the operator on one that didn’t.

01Leeds, UK
Six thousand pounds for a conversion audit and what I got was a 42-page deck, half of which was screenshots of my own site. The one change it was confident about was moving the guarantee badge up, which I’d already shipped. Darwiny tested it in week one, and it lost. What actually won was putting the size chart above the buy button. Nobody on that project ever said the words “size chart”.

First two weeks I hated it. It kept promoting a variant I thought was ugly: huge price, small photo, all the copy shoved to the top. I only let it run because I’d already paid for the month. It’s been my control since March. Nothing I’ve drawn beats it. I still think it’s ugly.

I keep my own numbers in a spreadsheet, so I ran the six weeks against it expecting to catch it lying. Revenue per visitor 22.40 to 26.80. Same spend, same audiences. It reconciles.

The variant that beat us moved the shipping cutoff next to the price instead of burying it in the footer. That was the whole change. We’d spent a year arguing about the hero image. I won that argument.

Set it up the Thursday before a long weekend and forgot about it. Monday there were four pages running and one was already ahead. That was April. I’ve opened it twice since, both times to check it hadn’t broken.

It’s not magic. Roughly two in three things it tries don’t beat the page already running, and it’ll happily spend a fortnight proving that. It never gets bored of trying. I managed three tests in four years.

FAQ

What merchants
actually ask.

The questions every Shopify operator asks before saying yes - answered straight, without the marketing fluff.

Your underlying store stays 100% the same - no theme edits, no replaced data, no migrated photos. On the product page itself, Darwiny renders a complete overlay: new hero imagery, copy, FAQ, layout, badges. Your header, footer, variant picker, price, and buy button stay exactly where shoppers expect them:

How the optimized page works

· Catalog & photos
· Pricing & inventory
· Customer data

Overlay renders client-side. Disable the script and your original page is back instantly.

No - every variant goes through the approval gate before it ships. The AI uses your live copy as reference when generating, and you reject anything that sounds off. Hero SKUs can stay manual indefinitely:

Approval gate · 2 approved · 1 needs edits · 0 pending
V1

Benefit-led bullets
V2

V3

Objections above fold

No - Google's own docs say A/B testing is fine as long as you don't trick the bot. Googlebot and your shoppers see the same set of variants. We don't show one thing to crawlers and another to people:

How variants are served
No UA sniffing
Googlebot
Crawls every variant at the canonical URL
Shopper
Cookie assigns one variant, sticky for 30d
Per Google Search Central - "A/B testing & your website"

It speeds it up. Each variant ships as leaner HTML - only the CSS this page actually uses, images sized to the visitor's device, and the variant decision happens at the CDN edge before any JS runs. Typical Core Web Vitals come out faster, not flat:

How variants come out faster
Only the CSS this page uses - inlined, not bundled
Images right-sized to the visitor's device + format
Variant chosen at the CDN edge - no client-side flash

One line. You paste a single `<script>` tag into your `theme.liquid` - that's the only change. Sections, snippets, templates, product data, and your other apps stay untouched. To uninstall, delete that one line and your original page is back on the next load:

Agencies ship 1–2 tests a quarter for $5k-$15k each. Shopify native splits traffic but won't write the variants. Darwiny generates, tests, and keeps evolving - for the price of a Klaviyo seat:
