App details

Theme Scientist A/B Tester

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.

Community driven

We're dedicated to providing the best A/B testing tool on Shopify and continue adding new features. We take requests and build features for you.

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 Product A/B testing work?

  1. Use the app to select a product
  2. Change the product attributes on version B
  3. Start the test and let it gather data
  4. Check the stats in the app to see which version is winning

The app will swap the 2 versions every day at midnight and track the stats.

How does Theme 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 and analyze your stats to see which website features / version performs better

The app will swap the 2 versions at the interval you choose (daily, hourly, etc) and track the stats: Orders, Sales, Adds to cart, Visitors, Sessions, Page views.

How long to split test?

2 weeks is a good minimum time frame but 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.

Free 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

Built with performance in mind

Our A/B testing works in the backend so this app won't affect your load speed like other apps.

In the store front there is 1 small analytics pixel that loads at the end of the page so it does not cause render blocking.

    Great app! Our team has been using this app for over a year to run A/B tests on products and website features - always testing something. We use a set it and forget it style: create a test, wait a few weeks or so, analyze the results, then start another test. The best for us has been testing product prices. Finding a better product price is golden!

    I really like the interface and i am nearly fully happy! BUT i would like to set the swapping times to something uneven, like 1/3/5/7/9 hours in order to really give every option the same time frames during a day.
    If i put my A/B test to swap every 4 hours for example, A would get 8-12 and 16-20 o clock every single day, which would mix up by swapping them every 3 hours. I would love, that you update this feature in the near future and ill happily give you 5 stars Great job guys! Love the update! Cheers :)

    Thank you for the feedback. We often implement new features based on request, and this sounded like a great idea. Our team went ahead and added the additional interval options to both Theme A/B tests and Product A/B tests the very next day!

    If you have any other feature requests, please email us. Our team is here to make Theme Scientist better for all Shopify Merchants!
