Expensive vs Complementary Product #7

I hope that you already know about split tests and the only way to fine-tune your sales funnel is to split test it!

Prerequisite
— You should have knowledge about creating widgets

Let's discuss the strategy!

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 or Popup vs In-Page #4 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

How to use translations editor properly?

• 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
