What is the specific function of the 'Fetch as Yandexbot' tool beyond simply showing how the page renders?

Beyond simply showing how a page renders, the 'Fetch as Yandexbot' tool in Yandex Webmaster serves the specific function of diagnosing indexing and crawling problems by allowing you to see the page as Yandexbot sees it. Specifically, it reveals whether Yandexbot can access and render all the critical content on a page, including JavaScript-rendered content, CSS styles, and images. It provides insights into potential issues preventing proper indexing, such as blocked resources, rendering errors, or slow loading times. The tool allows to identify if crucial page elements are not visible to Yandexbot, which could negatively impact rankings. For example, if important text content is rendered by JavaScript and 'Fetch as Yandexbot' shows that this content is not visible, it indicates a need to optimize JavaScript rendering for search engines. Furthermore, 'Fetch as Yandexbot' displays the HTTP status code, confirming whether the page is accessible, and highlights any server errors. It also lets you see the raw HTML code that Yandexbot receives, allowing you to verify that schema markup and other structured data are implemented correctly. You can also submit the fetched URL directly to the index after a successful fetch.
