10 A/B tests worth running first. With the prompt for each.

Ten setups worth running first on a webshop or a SaaS site, and the exact prompt to give your AI agent for each. Not a list of proven winners: each setup says where to test and why, what A and B could look like, which goal decides it, how much traffic it needs and whether autopilot may launch it.

What's inside

How much traffic a test needs, then ten setups, each with a prompt you paste into Claude, ChatGPT or Cursor.

  1. 1

    Before you start

    Why many of these tests will end not conclusive, how the prompts work, and what your agent does and never does.

  2. 2

    How much traffic each test needs

    The planner's numbers per conversion rate, what a detectable change means, and why a goal close to the change needs fewer visitors.

  3. Test 1

    The headline above the fold

    Lead with the outcome the visitor wants, in their words. Decide on the click under it.

  4. Test 2

    The main button: say what happens next

    "Book a demo" instead of "Submit": the label names the next step.

  5. Test 3

    Real reviews where people hesitate

    Move the reviews and ratings you already have next to the price and the button.

  6. Test 4

    The product page above the fold

    On phones: the price, the key facts and the button on the first screen.

  7. Test 5

    Delivery and returns next to the buy button

    Your own policy's words, where people decide.

  8. Test 6

    A sticky buy button, on phones only

    The same button, pinned to the bottom of a long page.

  9. Test 7

    The collection page: less in the way of the products

    Intro texts and banners below the grid, filters up.

  10. Test 8

    The pricing page: which plan stands out

    Highlight and describe plans differently; prices never change. A person approves this one.

  11. Test 9

    The lead form: the friction around it

    The heading, the button and what happens next; removing fields is a code test.

  12. Test 10

    Guarantee and trust wording near the decision

    The guarantee or trial terms you really have, in one sentence under the button.

Why an account

Read it, then try it on your own site.

Every prompt in it runs against Duelpilot. With your account you can connect your AI agent right after reading and let it check test 1 against your own numbers: choose a plan, connect Claude or ChatGPT with one prompt, and it installs the script and prepares a first test you approve. Autopilot is on Pro and up.

There is no free plan, but there is nothing to pay for the 10 tests, and every plan is €0 until you launch your first test: setting up is free, and your plan (from €9/month) starts when you launch. No launch within 30 days? We cancel it and you pay nothing.
