A/B testing and profit optimization

Test everything. Grow profit, not guesswork.

Run experiments on price, content, offers, shipping, and checkout, and see which version earns the most profit per visitor. Because the platform owns the whole stack, the numbers are exact, not estimated.

Most testing tools sit on top of your store as scripts. They estimate profit from numbers they cannot see, they lock price and checkout testing behind an expensive plan, and they fight the storefront cache, so shoppers catch a flash of the old price before the test version loads.

Mercemur runs experiments natively. It holds your real prices, cart, checkout, orders, and product cost in one place, so every test measures true profit per visitor from your actual costs. Price and checkout testing are on from day one, and the winning version is chosen on the server before the page paints.

You get decisions you can trust, not a dashboard of estimates.

Test the whole funnel

From the moment a visitor lands to after they buy. Every stage of the journey is a lever you can test or personalize.

Content

Headlines, hero sections, and page content. Test what a visitor reads from the moment they land.

Pricing

Product prices, subscription prices, and per-currency prices. Find the price that earns the most profit per visitor.

Offers

Automatic discounts and gift-with-purchase. Test the incentive that lifts the order without giving away margin.

Shipping

Flat rates and free-shipping thresholds. Turn shipping into a profit lever instead of a cost.

Checkout

Order bumps, reassurance copy, and trust badges. Turn more carts into orders.

Post-purchase

One-click upsells charged to the saved card after the order. Make more on every sale.

Profit per visitor, measured for real

Other tools estimate what a test earned. Mercemur knows. Because your real cost, discount, shipping, and tax all live in one system, every experiment reports true profit per visitor and holds a high bar before it calls a winner.

  • Deterministic profit per visitor, computed from your real product cost, discounts, shipping, and tax, not an estimate.
  • Bayesian and frequentist statistics with a sequential correction, so you are not fooled by an early peek.
  • A sample-ratio guard that flags a broken split instead of quietly reporting a wrong winner.
  • A minimum-runtime gate, so a test never declares a winner on a day of noise.
  • Results broken down by device and country, not just one blended number.

Describe a test. Understand the result.

You do not need a growth team to run experiments. Describe the test you want in plain words and it is built for you, ready to review and launch. When results come in, ask why a version is winning and get an answer grounded in your actual numbers.

Build it from a sentence

Type "try 10% off hoodies for mobile shoppers" and get a valid experiment draft, the right type and change, filled in and ready to launch.

Ask what happened

Ask which version is winning and why, in plain language, answered from this experiment's real results, never a made-up story.

The right experience for every visitor

Target a test to the visitors that matter, by new versus returning, device, traffic source, or customer group. Or turn a winner into permanent personalization, so the right audience always gets the right experience without an ongoing split.

Fair by design

The features that other platforms gate behind their most expensive tier are on from the start, and the platform never profits from your wins.

  • Price testing and checkout testing on every plan, not locked behind an expensive enterprise tier.
  • Zero transaction fees. The platform never takes a cut of the sale a test helped you win.
  • Server-side, flicker-free assignment. The right version is chosen before the page paints, so a shopper never sees the old price flash to the new one.
  • One sticky experience per shopper. A returning visitor always sees the same version, never a jarring flip.

Frequently asked questions

The whole funnel: content and headlines, product and subscription prices, per-currency prices, automatic discounts and gift-with-purchase offers, shipping rates and free-shipping thresholds, checkout content and order bumps, and one-click post-purchase upsells. You can also run several changes together in one combination test.

From your real numbers, not an estimate. Because your product cost, discounts, shipping, and tax all live in the same platform, each experiment computes true profit per visitor. That is the headline number, so you optimize for what you keep, not just revenue.

No. The winning version is chosen on the server before the page is drawn, so a shopper never sees the original price or content flash and then jump to the test version. Each shopper also stays on one consistent version, so a returning visitor never flips between prices.

No. Price testing and checkout testing are available on every plan, including the free tier for a single running experiment. Other platforms gate price testing behind their most expensive tier; here it is a starting feature.

Every experiment uses proper statistics, a Bayesian probability alongside a frequentist test with a sequential correction so an early peek does not mislead you, a sample-ratio guard that flags a broken split, and a minimum-runtime gate so no winner is called on a single noisy day. Results also break down by device and country.

Yes. Target a test by new versus returning, device, traffic source, or customer group. You can also switch a winner into permanent personalization, so a chosen audience always gets the chosen experience rather than a continuing split.

No. Describe the test you want in plain words and it is built for you as a ready-to-launch draft. When results are in, ask why a version is winning and get a plain-language answer grounded in the real numbers.

No. There are zero transaction fees. The platform never takes a cut of a sale your test helped you win.
