This page contains information about site violations that Yandex detected. These may be, for example, overly-optimized pages or concealed text on pages. For a list of unfair methods of site promotion that may incur restrictions on your site, see Low-quality sites.
If violations were found on your site, notifications appear on the service's page, along with recommendations for correction.
To notify Yandex that you have eliminated the violations, click I've fixed everything. This sends an additional signal to the Yandex algorithms that the site needs to be re-checked. If the site was checked successfully, the restrictions will eventually be lifted, and the information about violations will be removed.
