RSS feed restrictions

Tip. If your site contains a large amount of data, you can send information in parts. To do this, create an RSS feed that doesn't exceed the limit, and upload it to Yandex.Webmaster. When the RSS feed is processed (within an hour), update it — add the item elements for other pages. These changes are sent to Yandex automatically.
