Yandex is testing a double block of quick responses in search results. The experiment was noticed by Ilya Gorbachev, head of SEO Rocket, who shared screenshots on his Telegram channel. In the new form of the quick response block, Yandex search results display data from 2 sources at once.
Such a block is quite rare and appears only for the most common requests that can be divided into subtopics, Ilya noted.
