In this experiment, popular search terms were added at the bottom of a long e-commerce homepage. Hence, the variation showed additional search triggers that lead to results pages. (Translated from Russian using Google Translate)

In this experiment, the discounted price was shown along with an active promotion. The control only showed that the relative -8% discount was present with the pre-discounted price.

In this experiment, products which were out of stock were removed from listing pages and replaced with in stock ones (not visible in the screenshot).
