Ratings are calculated based on multiple factors including the number of published reviews, specific user ratings, and other data.

When you correct details of an organization, its place card on Yandex Maps is updated automatically. However, your edits will have to pass moderation. Until then, you're the only person who can see these changes (as well as the message “Thanks for updating information about this organization!”). Your edits will become visible to all users after the moderator determines they don't infringe any rules or regulations on the disclosure of information. If you are a company representative, use Yandex Business to make changes to your organization.
