What works in e-commerce – A meta-analysis of online experiments [pdf]
tl;dr: The 3 items possibly statistically significant are:- Saying there are just a handful items left in stock (+2.9% revenue per client)
- Saying other people are watching this product (+2.3%)
- Time limited offer (+1.5%)I did not see mention of combining these factors. I doubt the gains are cumulative.My main takeaway is that most optimizations are not worthy if you have the opportunity to spend your time/money on something else to bring value to the consumer.Also, I think #1 and #3 are dick moves and #2 needs some good crafting to not be. I doubt the cost in reputation is worth the increase in revenue.
