About Theme Scientist A/B Tester

A/B testing is key to maximizing your conversion rate.

Theme Scientist is an easy to use A/B testing app for Shopify.

Increase sales without buying more traffic

Improving conversion rate maximizes the value on your website traffic. A single successful experiment can lead to massive long term gains in revenue.

How to increase conversion rate?

Use A/B testing to compare site elements and product attributes, then get data driven results and implement the winners.

How does website A/B testing work?

  1. Duplicate your live theme
  2. Make a change to the new theme (maybe the add to cart button color)
  3. Choose the 2 themes to test and start the A/B split test
  4. Check back in a few days and analyze your stats

The app will automatically rotate the 2 themes every day at midnight and track the stats: Orders, Sales, Adds to cart, Visitors, Sessions, Page views.

Free theme A/B test setup

If you need help editing a theme to perform your first test, contact us and we'll make the adjustments for free.

How does product A/B testing work?

  1. Use the app to select a product
  2. Change the product attributes or image order on version B
  3. Start the test and let it run a few days
  4. Check the stats in the app to see which version is winning

How long to split test?

2 weeks is a good minimum time frame (so each version sees all 7 days of a week).

The longer a test runs and the higher the statistical significance level, the more accurate your results will be.

What is statistical significance?

This is a mathematical formula to predict the probability that 1 version is better than the other.

Theme Scientist includes statistical significance calculations for every A/B test.

Theme scheduler feature

You can set a theme to publish at a specific time in the future.

This is great for publishing promotions at exactly the time you want without having to be online to make changes or set a new theme live.

The scheduler is also useful for running daily flash sales where new themes / graphics need to be swapped every hour.

Who this app is for

  • If you want to increase your conversion rate
  • If you want to maximize the value of your inbound traffic
  • If you want to learn what customers in your niche respond to best
  • If you like automated tools

Built with performance in mind

Everything with the A/B testing features happens on the backend, so this app won't affect your load speed like other apps.

In the store front, there is 1 analytics pixel that's lightweight and loads at the end of the page so it does not cause render blocking.

Chef's Vision

Super clean, powerful app that lets you alternate between themes for split testing. Being able to customize an entirely separate theme gives you almost unlimited flexibility to tweak and test.

It tracks the views, add to carts, conversion rates, and provides statistical significance levels so you know when to choose the winning version.

The team behind the app are great, I hired them in the past to speed up my site and add lazy loading to images. They're very responsive, always improving and building new features and products based on suggestions.

I used this app to run a test on the color of the buy button. It was easy to set up and it ran without a hitch. I did get a clear winner. I had an idea to make it work better and reached out to Joe, the founder. He was very responsive and did implement my suggestion. I highly recommend this app.
