The Kniha.cz e-shop, owned by the Mladá fronta publisher, wanted to make shopping easier for its customers, so they decided to personalize the website.

First, we tested Persoo in an A/B test, where 50 % of users saw the personalized variant and 50 % did not. Total turnover got an increase of 35 % during one month of A/B testing. This happened mainly due to the higher number of books purchased per transaction.

Where was the problem?

On the websites, there were places for cross-selling and upselling, containing a default offer of books that was the same for every visitor.

How did it end up?

Thanks to personalized recommendations, people often buy multiple books from the same author in one purchase, whether it’s a sequel book or just an impression of a favorite author’s name.
