What to test

Change a thing. Let the sales decide.

Show two versions of the same page to your real shoppers. Zyro counts the sales from each and tells you which one wins, no maths degree needed.

Copy

Try a new headline or value prop. "Free shipping" versus "Ships in 24 hours", decided by your buyers.

Imagery

Swap product photos. Does a lifestyle shot beat a plain white background for the way your shoppers actually buy?

Layout

Move sections around. Put reviews above the fold or rework your buy box, then see what it does to revenue.

The clever part

Instagram people and Google people don't buy the same way.

Most A/B tools treat your traffic as one blob and hand you one average winner. Zyro checks every test for each place your visitors came from, so the version that wins for Instagram can differ from the one that wins for Google. Each shopper then sees the right one.

Same test, split by where your visitors came from

The stats engine

Built to call winners you can trust.

Zyro reads results with Bayesian statistics, targets the audiences you care about, and protects your revenue while every test runs.

Bayesian stats

See the probability one version beats the other in plain English, so you stop tests when they're genuinely settled.

Audience targeting

Run a test only for a chosen source, device or visitor segment, then read the result for that audience on its own.

Auto-pause on losers

If a version starts losing sales, Zyro pauses it automatically and your original comes straight back. Your revenue is protected.

How it works

Three steps to a winning test.

Launch experiments without a developer.

1

Set up the test

Create an experiment in Zyro and pick what you want to try, a headline, an image, a layout.

2

Build the variant

Set up your alternate version and choose which audiences and sources should see it.

3

Launch

Split your traffic and start. Zyro handles routing, counts the sales and calls the winner per source.

Fair questions

The things you're right to ask

What is A/B testing, actually?

It means showing two versions of the same page to find out which one really sells more. Half your visitors see version A, half see version B, and the sales decide. No opinions, no guessing.

How is this different from a normal A/B test?

Standard tools treat all your traffic as one blob and give you one average winner. Zyro checks each test for every traffic source, so the version that wins for Instagram shoppers can differ from the one that wins for Google, and each visitor sees the right one.

What if a test loses me money?

Zyro watches every test while it runs. If a version starts losing sales, it gets paused automatically and your original comes straight back. You see what happened in plain English.

Do I need a developer?

No. Paste one snippet, the same way you added Google Analytics, or use the 1-click Shopify or WooCommerce app. Everything after that happens in your dashboard.

Turn opinions into data.

Stop arguing about which headline is better. Put one snippet on your store and let your customers decide with their wallets. The free plan is real.
