Prior to closure, webmasters used the Catalog to improve the position of their sites in the issuance of Yandex: registration in the Catalog affected the SEO performance of the site. As a result of applications for additions became so many that this led to the collapse of the service. At the same time, the quality of content on many sites began to decline, and Yandex.Catalog ceased to be a platform for quality resources.
After the Catalog was closed, its functions were transferred to Yandex.Webmaster.
