Stage 2 · Testing and CRO

More tests that move take rate and revenue per visitor.

CRO used to spend most of its time on design and development. Our engineers and PMD Cortex AI have sped that part up, so our time goes on shipping more and better tests, pages and offers that let you scale paid spend.

Where the time goes

Less time building. More time testing.

Our engineers each run a bench of AI bots that handle the design and build legwork. An engineer checks every output, so the hours you pay for go on deciding what to test and shipping it.

How CRO used to run

Most of the month went on making things

  • Most of the hours spent designing and developing each new page or variant
  • Few tests live at once, because building was the bottleneck
  • Results judged on conversion rate alone
  • Learnings kept in slide decks and people's heads

How we run it now

Most of the month goes on what to test

  • Bots draft the design and build work, engineers review and ship it
  • More tests, pages and offers live in the same time
  • Every test judged on subscription take rate and revenue per visitor
  • Every result feeds the CRO Brain inside PMD Cortex AI

The numbers we answer to

Two metrics decide if a test wins.

Subscription take rate

The share of first orders that start a subscription. Lift it and each customer you pay to acquire is worth more over their lifetime, so you can afford to bid harder on ads.

Revenue per visitor

Conversion rate and order value in one number. A test that lifts conversion but cuts order value does not count as a win here.

Real tests

Why it won

The one-time price now sits next to the subscription price, so the saving is visible at the buying decision. It set the pattern for how savings are shown across the whole funnel.

Where your budget goes

One budget, six kinds of work.

What your testing programme pays for, in the order a test gets made.

  1. 1 Research Customer surveys, reviews, heatmaps and your analytics, read before anything is designed. CRO strategist
  2. 2 Copy Angles, headlines and offers written from what your customers actually say. Copywriter
  3. 3 Design Page and variant designs in Figma, checked against your brand. Designer
  4. 4 Development Pages and tests built on your theme, with bots doing the legwork. Shopify developer
  5. 5 QA Every build checked on every device before it goes live. QA specialist
  6. 6 Testing A/B tests run, read and rolled out, judged on revenue per visitor and take rate. CRO strategist

One programme budget pays for all six. Our build bots now do most of the design and development legwork, so more of your budget goes on the research, copy and tests that grow revenue. We agree the split with you in your audit.

Our own testing app

We built AB Genius to run tests inside Shopify.

Price, theme, template and checkout tests inside your Shopify store, reported on revenue and profit. Our pods use it on client stores, alongside Intelligems where a brand already runs it.

  • Tests read on revenue per visitor and profit, not clicks
  • Built and run by our own team
  • Every result, win or loss, goes back into the CRO Brain
