Yandex have added new XML sitemap declarations for applications and games to their robots.txt file:
Sitemap: https://yandex.ru/games/sitemaps/sitemap.index.xml
Sitemap: https://yandex.com/games/sitemaps/sitemap.index.xml
This could be a sign that they are working harder on having their app store indexed, and given the number of moving parts at Yandex around personal finance, entertainment, and FMCG/personal shopping – I wouldn’t be surprised if they made more gains in the personal entertainment sector with video games and applications.
