I analyzed Ozon's main competitors—Wildberries, Yandex.Market, and Megamarket—and compared their product search and purchase scenarios for both new and registered users.
I had to revisit and update this analysis several times, as marketplace apps have complex structures and a huge number of use cases. Even for a single user, the same screen can vary significantly depending on the context.
Marketplaces update frequently and introduce new features, which was noticeable even during this short project. The most successful solutions are quickly adopted by competitors, while others remain unique to a single service.
