# Expensive vs Complementary Product #7

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 widget offer type 
|| (upsell offer #1 vs cross-sell offer #2)

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

1. **Split test Version #1:** Showing `complementary product` (cross-sell) for the main product

2. **Split test Version #2:** Showing `upgradable product` (upsell) for the main product

So at the end of split test, we will get to know whether customers are more likely to prefer buy ***upgradable version*** of the product or ***existing product with add-ons*** 

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 a version #1 Split test offer widget 

We've already know how to 

* Create a widget with `cross-sell` offer

* Select complementary product as offer product

So let's move to the second step. 

### 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 type to `upsell`

* Change the product with the `upgradable product` and remove the old product from `split test #B`

* Don't forgot to change the `Translations texts`

* `Save & Publish` the funnel

So our **split test #A** **contains** **cross-sell** offer and **split test #B** **contains** **upsell** offer

### 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`
