Intimate goods stores, not in Yandex's top 100?

Question

Google

Good day! Faced a problem. There are two sites for the sale of intimate goods (they are not related to each other, different owners, content, etc.). The texts on them are unique, there is no spam, the meta tags are correct, all the main technical problems have been fixed.
On both sites, the positions are over 100, I haven’t come across the topic before, I can’t understand the reason.
If someone had a similar experience, please tell me what could be the problem, or in which direction to "dig".
Unfortunately, I can't name the domains.
