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.
New for 2021
We're dedicated to providing the best A/B testing tool on Shopify and have already added new features this year. 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?
- Use the app to select a product
- Change the product attributes on version B
- Start the test and let it gather data
- 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?
- Duplicate your live theme
- Make a change to the new theme (maybe the add to cart button color)
- Choose the 2 themes to test and start the A/B split test
- 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.

Soin Amalthée, le savon au lait de chèvre naturel et fait en France
It's the perfect tool to run AB Test on the Theme, simple and efficient. Unfortunately, at the moment I start an AB Test, I have visitors from the US, tons of visitors and all my KPIS are skewed. That's very sad.
We appreciate the compliment on our app, but not sure exactly how to respond here :) ... All our app does is swap the test versions, read the data, and report the statistics on the actions they take (visitors, page views, orders, etc). We can't control the people in a specific country that visit your site (would love to help send you more traffic but that's impossible).
Tried reaching you by email, we like stats and analytics so would be happy to help you out.
Not sure why we're getting the blame here but we're friendly folks, just contact us and we'll do our best to help out.
The best split-testing app I've tested so far, there is everything I need and the customer service is super reactive!
I also suggested a new feature and it got added !! 100% recommended
Love the enthusiasm, thanks! We appreciate the feature suggestions and will continue adding more :)
