Deleting a site
How do I exclude a site or some pages from the search?
Remove the pages from your site (so that the server returns the404 Not found HTTP status code when the URL is requested) or prohibit their indexing in robots.txt. Then use the Delete URL form.
Next time the robot crawls your site, the pages you deleted or prohibited from indexing will be excluded from the search results.
The Yandex search output contains information removed from the site for copyright violation. Please take action.
Once the robot detects that the page is deleted, it will remove the page from the index. To speed up this process, use the Delete URL form.
