Why does Yandex not index pages like site.ru/lechenie-alkogolizma/alcoholism-and-dipsomania/ with this robots.txt file:
User-agent: Yandex
Disallow: /administrator/
Disallow: /cache/
Disallow: /cli/
Disallow: / components/
Disallow: /includes/
Disallow: /installation/
Disallow: /language/
Disallow: /libraries/
Disallow: /logs/
Disallow: /media/
Disallow: /modules/
Disallow: /plugins/
Disallow: /templates/
Disallow: / tmp/
Disallow: /share42/
Disallow: /wm/
Disallow: /404/
Disallow: /component/
PS for Google, the same installation costs and everything is OK, pages of this kind are in the Google index. Please help me figure out what is the reason?

Answer 3

In the webmaster panel in the added and verified project, there is a "check url" section. Throw your page url there and write here what's there.
