83 | Notify returning visitors: still products in shopping cart | Mobile

This hypothesis is grounded in the following psychological principles:

1. Motivation: The impulse to act is often triggered by personal relevance and perceived benefit. In the context of online shopping, this translates to the desire to acquire items that a user has already considered buying. A reminder can reignite the initial interest, leveraging the natural human tendency to complete tasks that have been started.
   
   
2. Ability: The ease with which an action can be performed directly influences the likelihood of that action being taken. In e-commerce, simplifying the checkout process makes it more probable that a visitor will proceed to purchase. A direct reminder about items in a shopping cart can act as a shortcut, reducing the steps to completion.
   
   
3. Attract attention: In a crowded digital landscape, capturing a user's attention is crucial. A notification (in this case a popup) can serve as a visual cue that brings the user's focus back to the items they were interested in, thereby increasing the chance of conversion.

Based on this theoretical background, we believe that providing a reminder to returning visitors on mobile devices about their abandoned cart items, will increase their propensity to complete the purchase. We will know this when we see online transactions increase.

The experiment results shows that we have evidence that targeted notifications can successfully convert intention into action by harnessing existing motivation and facilitating the transaction process. It also highlights the importance of attracting attention and relevance in communication with website visitors.

General
All A/B tests in Evidoo have been analysed using Bayesian Statistics. The most important advantage of Bayesian statistics is that it is easy to understand. If there is a difference between the control and the variant, we determine the probability that there is a difference. The probability that the variation differs from the control, is indicated in a percentage.

An A/B test labeled as ">80%" (winner), indicates that the hypothesis has a high probability (>80%) of being true.

An A/B test labeled as "21 - 79%" (inconclusive), suggests the hypothesis has an intermediate chance of being true. This probability range indicates that there is still uncertainty regarding the hypothesis. Therefore it can not be clearly categorized as true or false.

An A/B test labeled as "< 20%" (loser), likely represents a hypothesis that has less than a 20% chance of being true. This suggests that the hypothesis is likely false.

If the primairy KPI is ‘transactions’, there is no impact on average order value, unless mentioned in the learnings.

All A/B tests in Evidoo are also analysed on secondary KPIs, for example 'add to carts'. If we found remarkable results on other KPI’s, check the tab 'learnings'. We also analysed different segments, for example 'new visitors' or 'returning visitors'. If we found remarkable results on specific segments, check also the tab 'learnings'.

All conducted A/B tests in Evidoo comply with:
- conducting sample size and power checks.
- performing the experiment only after an A/A test has been completed.
- implementing Sample Ratio Mismatch (SRM) checks.
- maintaining a minimum runtime of 2 weeks.
- measuring A/B tests only when they are visible to the website visitor, such as counting an A/B test in the middle of the product page only if the visitor has scrolled to that point.
