In short. Yandex documents indexed pages as the source for automatic Yandex AI answers.
Definition: Yes. Yandex's Webmaster guidance says that Yandex AI answers are generated automatically from pages indexed by Yandex. The documentation describes indexing as the process that stores and processes page data before Yandex builds the database of pages that can enter search results.
Key facts
- Yandex AI answers can appear automatically or after a user activates the feature manually, according to Yandex's Search with Yandex AI guidance.
- Yandex defines indexing as saving pages to its database and processing them with algorithms, as described in its search indexing documentation.
- Yandex says a page restricted in
robots.txtcan still participate in search, according to its robots.txt documentation. - Yandex's page visibility guidance points to the Check page tool for checking whether a page is indexed as needed.
Does Yandex require indexing before using a page?
Yes, for the automatic use described in Yandex's AI guidance. Yandex states that its answers are generated from pages that were indexed by Yandex. Its search documentation distinguishes crawling from later loading and processing, then from creating a database of pages that can be included in search results.
The documented prerequisite is that the page is indexed by Yandex. The AI guidance does not state a separate requirement that the page must already appear for a particular ordinary search query.
What does Yandex mean by indexing?
Yandex's indexing documentation describes four stages: crawling the site, loading and processing the data, creating a database of pages that can be included in search results, and generating search results. During crawling, the robot uses known pages from internal and external links, Sitemap files, Yandex Metrica data, and robots.txt directives.
During processing, the robot analyzes page content such as the description meta tag, the title element, Schema.org markup, text, images, and videos. Yandex also says that a noindex directive in the robots meta tag keeps a page out of search results. At the database stage, pages with indexing disabled or duplicate pages are excluded from the database.
How can a site control and check AI use?
Yandex's AI guidance provides a site-level control for this use. A Disallow rule for either YandexAdditional or YandexAdditionalBot in robots.txt prevents the targeted content from appearing in Yandex AI answers.
User-agent: YandexAdditionalBot
Disallow: /cats/mycat.html # prevents the content of the page from appearing in Yandex AI answers
Yandex's general robots.txt documentation says that pages restricted in robots.txt can participate in Yandex search. It directs site owners who want to remove a page from search to use the noindex directive in the HTML or configure the HTTP header. The AI exclusion rule and the general search controls therefore address separate documented outcomes.
For inspection, Yandex's page visibility guidance points to the Check page tool under Indexing, and to Tools, Robots.txt analysis, Check if URLs are allowed. These tools show whether a URL is allowed for indexing or blocked from it.

FAQ
Must a page appear in ordinary Yandex search first?
Yandex documents the prerequisite as being indexed by Yandex in its AI guidance. The guidance does not state that a page must already be visible for a particular query.
Can robots.txt control Yandex AI use separately from search inclusion?
Yes. Yandex documents YandexAdditional and YandexAdditionalBot as robots.txt targets for preventing information from appearing in Yandex AI answers in its robots.txt guidance. The same guidance separately explains how noindex or an HTTP header removes a page from search.
How can you check whether a page is allowed for indexing?
Use Yandex Webmaster's Check page tool, or open Tools, Robots.txt analysis, Check if URLs are allowed, as described in its page visibility guidance. The tool reports whether the URL is allowed for indexing or blocked from it.
