Definition:

Yandex is a search engine used to find web pages, images, videos, news, places and other Internet resources. It has a strong specialization in the Russian language and in searches related to Russia and nearby markets, although it can also process queries and documents in other languages.

Yandex Search is the search product. It should not be confused with the technology company that develops it or with other products under the brand, such as Yandex Browser, Yandex Metrica or Yandex Direct.

How the Yandex search engine works

Yandex uses its own systems to discover documents, add them to an index and select answers for each query. The general process has four stages:

Crawling: Yandex crawlers follow links and retrieve accessible pages and resources.
Processing and indexing: the search engine analyzes the content, identifies its elements and decides which documents to store in its indexes.
Query interpretation: it examines the words, their linguistic form, the language, the intent and, when relevant, the user’s location.
Retrieval and ranking: it selects the documents and modules it considers most useful and organizes them on a search results page.

Crawling and indexing are different processes. A page that the robot can access may be left out of the index or may not be relevant to a particular search.

What appears in Yandex search results

Yandex combines results from its web index with information from other services. Depending on the query, it may display:

Web results: links accompanied by a title, description, address and other document data.
Direct answers: information presented on the results page when the search engine can resolve a specific need.
Images and videos: visual results related to the searched topic.
News: reporting connected with events and current topics.
Maps and local results: businesses, places, addresses and routes connected with Yandex Maps.
Advertisements: sponsored results distinguished from organic results.

Organic results, proprietary modules and advertisements perform different functions within the search experience.

Search filters and options

In addition to entering a standard query, Yandex provides tools for narrowing the results:

Region: searches can be limited to documents associated with a particular location.
Language: documents can be limited to one or more languages.
Date: users can find content published within a particular period.
File type: filters are available for formats such as PDF, DOC and XLS.
Operators: specific syntax can find phrases, particular words or documents from one site.

These options are part of Yandex Search and help reduce the set of documents that answers a query.

Differences between Yandex and Google

Yandex and Google share the function of finding information on the Internet, but they operate independent infrastructures and ecosystems:

Index and algorithms: each search engine crawls, processes and ranks documents with its own systems.
Language specialization: Yandex has developed particular expertise in Russian morphology and context.
Regional component: Yandex distinguishes between location-dependent queries and general searches.
Result presentation: their modules, snippets and integrated sources are not identical.
Associated tools: Yandex has its own platforms for webmasters, advertising, maps and measurement.

Yandex is not a browser either: the search engine retrieves information, whereas a browser is the application used to access web pages and services.

SEO for Yandex

SEO for Yandex aims to make a website easy to crawl, understand and index while providing useful answers for its intended audience. Its areas of work include:

Technical accessibility: pages, resources and links should respond correctly for the robot and users.
Architecture: internal links, URLs, the sitemap and crawling directives should represent the real site structure.
Content: each page should meet a specific need with clear, original and sufficient information.
Language and region: localization should match the audience, language and geographic scope of the project.
Search presentation: titles, descriptions, favicons and page data contribute to the visible snippets.
Diagnostics: Yandex Webmaster provides information about crawling, indexing and appearance in results.

Yandex also supports sitemaps, robots.txt, reindexing requests and IndexNow to communicate URLs and changes to its crawler. These signals support discovery, while inclusion and ranking depend on the search engine’s evaluation.

Yandex as a company and its other services

The Yandex search engine was presented in 1997 by Arkady Volozh and Ilya Segalovich and became the basis of a company and a broader technology ecosystem. Its products and business areas include:

Yandex Maps: maps, navigation and place search.
Yandex Browser: a web browser developed by the company.
Yandex Translate and Yandex Mail: translation and email services.
Yandex Metrica: measurement and analysis of website and application usage.
Yandex Direct: an advertising platform for search and other placements.
Alice: an assistant and a family of artificial intelligence technologies.
Yandex Cloud: infrastructure and technology services for organizations and developers.

Yandex Search is the search engine within this ecosystem; the other products have their own functions.
