# Jack vs Jill complementary products #6

I hope that you already know about [split tests](https://docs.helixo.co/en/article/whats-a-split-test-ab-test-how-to-use-it-effectively-1jd8cpv/) and the only way to fine-tune your sales funnel is to split test it!

Let's discuss the strategy! 

|| **Core Logic:**  Testing different versions of the **upsell / cross-sell products**

In this strategy, we are going to split test 2 versions

1. **Version #1:** Showing `product #A` while clicking on `Add to cart` button on `Product Page`

2. **Version #2:** Showing `product #B` while clicking on `Add to cart` button on `Product Page`

So at the end of split test, we will get to know which **product has high demand!** 

Then you can further use [Discount vs No discount + Coupon #3](https://docs.helixo.co/en/article/discount-vs-no-discount-coupon-3-zgsbhy/) or [Popup vs In-Page #4](https://docs.helixo.co/en/article/popup-vs-in-page-4-1n8fi59/) strategy to fine-tune the offer and displaying style.

### Step 1: Create an offer widget 

We've already know how to 
[Create a Simple Discounted Cross-sell Offer?](https://docs.helixo.co/en/article/create-a-simple-discounted-cross-sell-offer-10bpme/)

So let's move to the second step. This widget is the version #1 of split test.

### Step 2: Create the version #2 Split test

* Click on `Copy Widget` of version #1 > `Copy As Split Test`

* This will make the first widget as `Split test #A` and creates `Split test #B`

Now same copy of the widget has been created!

### Make changes to version #2

* On `Split Test #B`, Change the offer product to `Product #B`

* Make sure to keep everything else same, like the discounts, widget styles on both split tests, so the results will be solely depends on the products.
You can try other split tests with translation copy, discounts etc after find the results of this split test.

* `Save & Publish` the funnel

### Give some time for split tests to run!

* It's recommended to give at least `7 days` to run split test or at least `1000 impressions` to get the results

* If you give more time for split tests to run, will get better results.

### How to analyse performance?

* Click `View Analytics` on the funnel

* Check the numbers there, see the revenue and conversions

* We can clearly see that `split test #A` performs better

### What's next?

* You can run split test another 7 days - 14 days to get better results.

* If you still see massive rejection in a split test, it's doesn't make sense to keep it live.

* `Edit Funnel` and remove the **losing split test**, here it's `Split test #B`
