Correct and improve traffic bucketing on uneven Split URL Experiments

 

Sometimes, it occurs that you get uneven Split URL experiments where you see that the Original shows much more visitor traffic than the Variation does. Some of the traffic that was bucketed by the Site Area and Audience conditions might not make it into the variation, because it does not match the Original URL Pattern, resulting in more traffic on the original. 

Solution

To solve this, the following regex formula matches every URL bucketed by the Site Area and appends any parameters from the visitors' URL to the end of the Variation URL. This prevents uneven experiments caused by the default Transfer Query Parameters option.

It also transfers URL query parameters present on the URL in which was bucketed onto the experiment.

Change the Variations configuration to: 

Original URL:

([a-z]{1,2}tps?):\/\/((?:(?!(?:\/|#|\?|&)).)+)(?:(\/(?:(?:(?:(?!(?:#|\?|&)).)+\/))?))?(?:((?:(?!(?:\.|$|\?|#)).)+))?(?:(\.(?:(?!(?:\?|$|#)).)+))?(?:(\?(?:(?!(?:$|#)).)+))?(?:(#.+))?

Variation 1:

https://myvariationurl$7$6

The modal should look like:Summary_-_CRO-176___n_checkout_Offer_Table_Optimisation_Series___v1b_-_fixed_regex_-_Convert__1_.png
