If you look closely, the Russian Yandex takes the text of the anchor links on the page.
For example www.nix.ru/price/
— here is a link with the text "Price list".
And then on this page there are links to other subsections. To be sure, take for example laptops Roverbook, a link to which are not separately allocated. Type in Yandex: laptops roverbook nix. And see that Yandex is now not provides so beautiful a link instead: nix.ru "Price list" notebooks_roverbook.html
So you should have similar pages with all the topics that you would like to select.
